Repairing Counterfeit Flash Drives

Posted by KittyFireFlash on October 25, 2008

SOSFakeFlash has been asked by many victims of fake flash drive purchases - how to restore to the original true capacity? Electrostorm has provided excellent information to the tools you would need to deprogramme FrankenFlash.

See Repairing Counterfeit Fake MP Players For MP Players.

Mentioned previously (see: Did You Manage to Reprogramme a Fake Flash Drive Bought on eBay?), to repair a drive you need to know about the controller and the flash chips. To do this you need software that will provide this information. Once you have it, you need to find the right software to reflash the chip and perform the low level formatting of the drive. We are providing the links and steps submitted by Electrostorm. Understand that this could repair a fake – but not in all cases. You could lose the drive in attempting to repair – especially if you chose the wrong tool. Not all drives can be rescued and returned to their real capacity – but many have been.

To restore most fake capacity USB flash memory devices.

Step 1:

Download chipgenius, this program will automatically detect an inserted flash drive and read out the 4 digit VID code and 4 digit PID code.

http://www.mydigit.cn/mytool/ChipGenius.rar

If you don’t have a software that can unzip the “rar” format, please get the software 7-zip from:

http://www.7-zip.org/

Step 2:

Go to the iFlash website and search for a matching VID and PID, download the corresponding software from the site.

Translated to English (recommended)

In most cases I have been able to use the software provided to reflash the controller chip and do a low level format and restore correct capacity.

Once you have repaired the drive using the steps and software above – you need to format the drive in your operating system. After operating system formatting you should once again test the capacity of the drive to ensure that you have truly succeeded. Use the tool H2testw 1.4 once more again. If you are able to write, read and verify without errors – you now have a flash drive you can store data on. It may be a lot smaller but the capacity will be real.

If you chose to try and repair your drive using the information presented here, please return and leave your feedback indicating your success or failure in returning a drive back to it’s original capacity.

Update 20091023: Please consult the new FAQ at FixFakeFlash Inspectortech for important information on repairing fake flash memory items before you attempt to repair.

    TO InspectorTech-

    Thank you so much for you quick reponse. Sadly, I can’t explain how much this hurts me to hear that I’m unable to retieve my files back. I did just what you said. I pulled my photos and videos straight from my memory cards to the USB drive . I pulled the files off the memory cards because I needed to free up memory. I didnt save or copy ANY on my hard drive becasue I didn’t want a cluttered computer because I just got a new Dell Studio 15. I was in tears all day yesterday when I was unable to view my files and photos. So you’re telling me theres nothing to be done? I can’t get them back? Youre 100% sure? I had VERY important files! Photos and videos of family and friends. I just lost my uncle a few months ago and photos of him that family wanted. I had documents for court, all gone?

    Is this all true? I cant get anything back?

  4. I tried using udtools 1.0.4.9 and at the end of scanning i got a message write config table failed. Now the drive is showing 0 mb size . Ud tool have reported 512 MB . Not able to format also , giving an error writw protect switch is enabled , release it eventhough it doesnt have any switch for write protection. not sure what to do next. Can any one guide me ?

  5. Guys I did it agian with udtools 1.0.4.6 now the drive is operayional with 351 MB ,its identified as 512 MB , i guess the rest is gone bad sectors. One interesting thing is before running the dtools chipgenius retuened me below out put.

    Device Name: +[J:]+USB Mass Storage Device(USB2.0 Flash Disk USB Device)
    PnP Device ID: VID = 1221 PID = 3234

    Revision: 2.30
    Device Type: Standard USB device – USB2.0 High-Speed
    Chip Vendor: Ameco
    Chip Part-Number: MXT8208

    But Now i m getting different PID and VID as below

    Device Name: +[J:]+USB Mass Storage Device(Generic Flash Disk 2.0 USB Device)

    PnP Device ID: VID = 5136 PID = 4678
    Serial Number: 5&&134C9627&&0&&8

    Chip Vendor: (No match record)
    Chip Part-Number: (No match record)

    Product Vendor: Generic
    Product Model: Flash Disk 2.0

    Did i make any mistakes ? How come the PID and VID got changes now ?

  6. InspectorTech said

    Hi Tomy

    The vid and pid can easily change. In the manual configuration, the codes are set. So it depends on what the person who used the tool before you had when they uploaded the tool. This information is usually stored in an *.ini file. We don’t recommend that people change the manual settings for most it is hard enought just to use the tool.

    Your observations on the differences in the two versions of the tool (recognizing the flash chip drive or not) is correct. Some of these tools are beta’s – much depends on the configuration list they have for flash chips. Each has to be listed in a parameters table. Sometimes newer tools will drop older chips.

    Good to hear you suceeded!

    Why bother repairing a fake flash drive, when the result may be a 2GB flash drive that you should not trust with your data.

    Current retail in store prices for 2GB flash drives, in North America range start at $6 at Walmart (current flyer). Internet prices (@Walmart.com) are in the $6 to $10 range.

    What to do with the fake flash drive? Save for evidence in Mail fraud complaint?

    I had a Kingston DTI/512 DataTraveler which some how became write protected, although the unit does not ship with a write protect switch. I tried all the tools, methods, etc to get this drive working again until I came across this page, followed instructions…

    I had a Kingston drive:
    PnP Device ID: VID = 0930 PID = 6533
    Chip Vendor: Kingston
    etc etc …

    went to the iFlash website armed with the VID and PID info, downloaded the tool, followed instructions and discovered that this drive is an Imation Flash Drive with new VID and PID …
    PnP Device ID: VID = 0718 PID = 0083
    Chip Vendor: Imation

    Imation Data Traveler KINGSTON 512 Gb

    So I have a rebranded Imation drive in Kingston clothes…

    Needless to say, I have a working drive again :D

    THANKS to SOSFAKEFLASH !!!!!!!!!!!!!!

    On post #136 InspectorTech recommended

    It should NEVER EVER be fully trusted again, even if you can repair it and it passes H2testw. Always make sure you have a back up of files transferred to it.


    I would also recommend that you use a program/utility that will detect errors when you read data from the repaired flash drive. 7Zip uses CRC checking to verify that data being read has not been corrupted. The CRC is created when the data is added to the ZIP file and checked when the data is read from the ZIP file.

    There are other programs available that provide similar capabilities. Don’t rely on a Windows copy / paste commands to preserve data integrity.

    Also, when using a ZIP utility, create the Zip file on your hard disk then copy the Zip file to the flash drive. This will be faster, and extend the life of the flash drive.

    You may also want to put some markings on the repaired flash drive so that you will remember that it is not “trustworthy”.

    Dear InspectorTech

    My FAKE Drive:
    Kingston
    CCORE 32GB
    VID =DC08
    PID =EF0B
    CM3110

    After Detailed Analysis, I have come to the conclusion that: State CCore CCM3110 core volume production tool: MPT V2.4.0007 beta MAY Work on fixing the correct size of the FAKE Flash Disk.

    I have searched high & low for this App, but did not find it. I even tried Registering on the Chinese Website, but did not succeed.

    Please send the Program to me.

    I bought the Pend-Drive being AWARE that it WILL BE a Fake (From a LOCAL Vendor for a sum of NR300 (@$6.5)). But the desire to experiment lives on.

    I am not afraid of experimenting OR loosing the data (I have not stored anything on the drive). Awaiting the App, to check & fix the real capacity of the drive.

    Thanks & Regards
    Alap

    Hi, i managed to fix my fake 500GB Sony USB. Chips used where the Solid State Systems.

    I was expecting maybe around 2GB after fixing but instead it was only 256MB. Wow! Just when I thought it couldn’t get any worse.

  13. InspectorTech said

    Hi Rachel

    Those sony fakes at 500GB are actually very old fakes. The best true capacity size ever found in the end was about 512MB. Still you didn’t do too bad, some people only had a 128MB capacity.

    FlashChipTutor has a very large collection of Sony fakes at his site. People can find them all under the categories on the left side menu see http://flashdrivefacts.wordpress.com/category/brands-flash-devices/counterfeits-sony/ It is even broken down in to sub categories.

    Did you retest with H2testw 1.4 to verify that your repair was sucessful?

    Bought a counterfeit KINGSTON 64GB Datatraveler 150 via ebay (seller icemanpeterepete)

    This thief (who obviously not replies to emails) reassured me that it was a genuine product that comes with a full 5 year KINGSTON warranty – bullshit !
    I few days after receiving it I encountered problems and got in touch with KINGSTON – and sure enough it turned out that I’ve been flogged a counterfeit product.

    I have followed the suggestions above

    The url above takes me to a Chinese bulletin board – no solution what I can find.

    After opening up the thumb drive I read the following on the chip.

    S6668
    D5-M6C
    HLLFK-001K
    0917

    I’m not sure, but it looks like the chip actually is a 1K chip.

    I bought 2 fake pen drives in Ciudad del Este, Paraguay.

    Thay came in fancy package: http://img36.imageshack.us/my.php?image=1kenvase.jpg

    Even they both look much like the same, one is different from the other.

    I could fix the first one with MPTools.
    It was a Micov MW6208E – Samsung 8443 K9G8G08UOB 1 GB
    PCTools gave me VID 1221 PID 3234 – Micov MXT8208.
    As far as I could read chinese, seems that Micov MW6208E is the same than Micov MXT8208.
    If not, anyway, it works.

    I can not fix the second one.

    PCTools gives me this values:
    VID 1043
    PID 8012

    It is OnFlash 5188B – 56-1B08070047
    Looks like Hisun or Hynix.

    Already downloaded alcor tools, Ameco UDTools, iFormat2 1.32, MPTools, PortFree Production Program PDx8, and UDTools 1.04. I guess no one is recognizing it right.

    MPTools claims it’s HY27UT088G2M_1GB or K9GAGO8UOM_2GB
    Please, heeeelp.

  22. Randy said

    To Baobab

    Try Chipgenius to determine the controller model number. Some Chinese sites indicate the OnFlash 5188B to be an ICreate controller.

    The next challenge would be to determine the type of memory. The manufactures tools may not report the exact model number. They make some guesses or report the last memory type that was used.

    You may have to so some experimenting after you have determined what model number the controller is.

    Except for the techie-hacker who has totally NOTHING to lose, the ONLY “fix” for a fake drive is –

    THROW IT AWAY!!!

    You CAN’T trust the programming or components in that drive!

    Folks, this much more than just about being swindled or having your book report or Excell files scrambled in a fake flash drive.

    Thousands of these fake drives have been purchased on eBay and Amazon as graduation and birthday gifts and party flavors and are landing in the unwary hands of those who jobs cannot tolerate data corrupted by one missing digit. When you walk past a hospital or construction site or industrial plant, someone there is plugging a flash drive into computers for precise medical and drug formula info or to feed instructions to heavy machinery or control a chemical plant or an aspect of our communications infrastructure. Maybe even computers aboard military aircraft and ships! This is an insidious blight that deserves FAR more attention by media and government than it has.

    Please write to your local TV station and political representative about this pernicious blight! The person you eventually help might be you! Would you want the doctor or med tech managing your mother in a hospital to be carrying a fake flash?

    Further to Jame’s comment.

    There are numerious post on this blog about treating repaired flash drives as “untrustworthy”. The quality of the chips used in them is questionable. The repair process can reduce the lifetime of the flash memory and after repair the “bad block table” may be full.

    So yes destroy the drive and throw it in the garbage.

    However, the drive can have some uses. If you are going to repair and use one these fake flash drives, my recommendation is to put a visable label on the drive and only store files on the drive using Zip or Microsoft compressed folders.

    I recommended Zip and/or Microsoft Compressed folders for storing any files on flash media. This provides an “end to end data integrity” check. If you have a data error you cannot recover the file from the flash but you don’t propogate invalid information. You should never have a flash drive being the only copy of your important data so not being able to recover the file should not be problem.

    In the case of repairing a Music player is “data integrity” and issue?

    Hello,

    Great site! I discovered your website trying to understand why my new 8 GB Kingston Data Traveler does not work- I bought it a month ago in Thailand, it was working fine and I had put some pics etc. in it, but now I find that no computer (windows) can read the drive- they say it needs to be formatted, but they cannot format it! I bought it from a seemingly good shop. Now I tried your suggestion to use ChipGenius, and this is what the program says about my drive:

    To Sarkar

    Your next step is to go to the http://fixfakeflash.wordpress.com/ site. Check the categories for the usb controller. Then to download a recent tool.

    Much will depend on the flash drive storage chip, how recent. We have been getting reports that some can not be fixed with software most people use.

    The AMECO MXT6208/MXT8208 UDiskTools 1.0.4.6 (20081010) (see the post and link) tends to fix most recent usb flash drives. Older ones an older tool is sometimes needed.

    The two flash chip vendors of interest for you are:

    AMECO and Micov (older).

    No need for any fancy special software in Linux . If you have a fairly new kernel or Live cd distro you can just type

    lsusb

    that should easily give you the 4 digit VID code and 4 digit PID code.

    or do a
    fdisk -l
    if your drive is modified it should give a messy output that does not look normal to othere drives on your system

    lastly try a dosfsck i dunno if you should try to repair just leave it alone just to see what it thinks. if your drive is show fake info it will show there..

    Go to the categories:

    Flash Chip Vendor
    Flash Chip Part-Number

    and review the articles and links for software downloads. Your vid and pid do not match but that does not mean the software micov will not work. You may also need to consult AMECO (same family but newer).

    Don’t for get to let SOSFakeFlash know what works and also let me know at my site. I would post a new article for the vid and pid if you succeed to help others find it.

    In response to Alex’s comment.

    Unfortunately most of the manufacture’s tools are designed to work on Windows XP.

    Have a read of these posts.

    You may also want to open up the drive and confirm the controller model number. Chipgenus is usually correct on the manufacture but has difficulty with the exact model # in the manufactures product line.

    If you don’t have access to an XP system them you may have to resort to some of the non flashing solutions.

    I have a few doubts. In iFlash.ru it says this is a 8gb flash drive, but I see lots of people with different sizes… who should I trust, what’s the real size of this flash drive?

    I downloaded the software to fix this flash drive, but I got a message ‘not find chip info’ and ‘bad blocks too much’… what should I do? And one version says it’s a 256mb flash drive. Another version of the same software says it’s a 2gb flash drive.

    So, what’s the real size? And how do I fix it?

    In response to Garth

    What size does H2testw report for “ok memory” or real memory. This should be the approximate size.

    If you want to be 100% sure you will have to open up the drive and find out the details on the memory chip. Decodeing information is provide on this site.

    To Garth

    You need to test your usb flash drive for it’s true capacity using H2testw 1.4. It indicates the size of flash storage chip used. ChipGenius tells you about the usb controller chip used in the flash drive. To reflash you need to know the controller family to find the right software.

    The Russian site reports what victims have found with their fake. A VID PID is about the controller not the storage chip.

    Reflashing software contains a little database, on flash drive chips. Depending on the version it may or may not recognize the flash storage chip. It is a wrong assumption to think the lastest version of reflashing software contains more information on flash storage chips. Sometimes they drop older chips to be able to add newer ones.

    The only 100% guarantee to be certain on the “real size” of the flash storage chip used, is to open the flash drive. It can be difficult depending on the model. It is also possible to break a usb flash drive in the process. In some cases the bottom half is glued to the bottom casing to make sure it does not wiggle. Often it is the flash drive chip size of the board. So anyone who wants or needs to do this must be very careful and gentle!

    Once you find the rectangular flash chip, you then have to decode the entire serial and search for it on the internet. Most of the time you will find it, but sometimes not. See FlashChip Tutor site to read up on flash chip grading. Many people have found nothing more than hand written marker lettering – very bad sign! So the only true way to be sure of the flash drive chip is to take apart the item, decode the storage chip and then try to search it out. Be aware that manufacturers normally specify in bits, not btyes. If you see “Gb” they are talking bits, if you see “GB” they are talking bytes. 8 bits make a bytes so remember to divide by 8 if they use Gb.

    Back to the reflashing software. In a lot of cases when the chip is recognized, an algorithm is used, an approximation. There are too many chip variations to be 100% precise. Much then depends on the version of software used. It also depends on how it has decided to detect bad sectors and so on. Also nand flash chips do not like to be repeatedly reflashed, ie low level format. It is usually done once in a flash chip’s life time. It has been observed in testing that the more you do low level formats on a chip, the more it shrinks in final capacity, especially when you different softwares or the wrong one for the usb controller. Flash nand chips are a completely different technology, they are not like hard disks.

    The best comparision in true size is to test with H2testw 1.4 and also open the item and decode what the size is.

    It is very important for everyone to understand, that while a usb flash drive “looks” the same, it can have different storage chips used. We’ve see this a lot. Remember they are recycling low capacity chips and factory rejects that should have gone to the furnance.

    This brings up the last point. Trying to restore capacity can be an adventure, it can even be fun. However, any restored itme needs to be retested and never ever trusted. This means you can use it to transport files you have back ups of, or use to play movies or music that you have back ups of. Restored items should never be used to archive or store IMPORTANT INFORMATION ON! Not for one and only files! Ever!

    At some point if we don’t have to continue hunting down and investigating so many fake flash sellers we would like to publish more information on nand flash technology so people will understand it better in simple terms. Such as wear leveling, life span, how data is written, why it is very difficult to recover data compared to a traditional hard disk, why they can in theory be so much faster in access speeds…

    To Avi,

    Could you explain your problem in more detail.

    Are you having problems reflashing drive?

    See the two proceeding posts.

    hi ITGuy,
    i have 64 GB kingston datatraveler. most of saved data get corrupted.i think it is fake. it has FAT32 file system,but when i try to format it show only NTFS file system.so i use SP27608 software to formate it and successful to format it in FAT32, problem remains. i have use chipgenius and h2testw to diagnose problem and I am pasting the chipgenius and H2TestW reports below to better explain the situation.i have tried AlcorMP(081208) as advised on one site but unable to fix the problem.

    To Avi,

    H2testw output shows the drive to be fake.

    H2testw output also indicates real size 102MB! The size of the memory chip in this drive is most likely 128MB. The difference bettween the two values can be explained by overhead.

    I don’t think it would be worth your time and effort to fix such a small drive.

    Have you reported this as a fake to this blog and paypal / ebay?

    Hi,

    I bout a kingston datatraveler 200 128 GB stick from which I think it is fake:
    Chipgenius Data:

    VID: 1221
    PID: 3234

    Serial Number: 0001CFCFCFC5DCA1
    Revision: 2.40

    Chip Vendor: micov(???)
    Chip Part-Number: MXT8208

    Product Vendor: Udisk
    Product Model: Udisk 2.0

    H2testw formats up to a little more than 4 GB

    The Chip on it says
    MW8209
    IPM122541-1
    09HT0515

    The big chip
    M-ML-8G
    A511-0811001

    UDTools (Ameco_MW8209_1.1.1.0_090424)
    say: MT29F8G08MAD_1GB

    Which settings are correct now ? :-/

  47. Randy said

    To Jamie, when you said h2testw formats up to 4GB did you mean h2test2 tested to 4GB or that h2test2 reported 4GB OK?

    UDTools is indicating that it found a 1GByte or 8Gbit memory chip (micron). Unfortunately M-ML-8G is not a well known flash part number. But a reasonable assumption would be that 8G represents 8Gbit.

    The h2testw output will tell you it is a fake, also there are a number of post on comments on this site about how to verify kingston memory, have a look at them.

    In response to Murphy reguarding repairing / flashing a SDHC memory card.

    In my research I have not found a method of flashing memory cards on a PC using an USB card reader. My research indicated that upgrading the firmware on a SDHC & CF cards requires a specialised device that works with the ISP capabilities of the card.

    The VID / PID reported VID = 14CD PID = 8123 unfortunately is associated with number of devices from supertop and in your case most likely an usb reader not the memory card. It also is associated with a pen drive, which would explain the entry in flashboot.ru

    There are work arounds, but I don’t recommend them if you intend to use the card in cameras as you may loose your photos.
