Strange Problems with Pendrives

65 posts in this topic

I'm having a strange problem with one of my flash drives.

Running Win98SE, NUSB 3.3 installed. (also verified this same error on 2 other computers running NUSB)

I have 2 flash drives, one is 256mb and the other is a new Kingston 16gb Data Traveler.

When I first installed NUSB, they both worked fine, and I could read/write to/from both of them. A few days ago, I tried to use the 16gb disk and it is recognized properly as a disk drive, but when I click on it in Windows Explorer it says

"The disk in drive G is not formatted. Would you like to format it?"

The other (256mb) flash disk is not affected. The 16gb disk shows up fine in Windows XP and in openSUSE 11, is read/writable and shows as being formatted with FAT32.

Any ideas on why this disk is suddenly not recognized properly by Win98?

On a last note, I did notice that the 16gb disk now has over 2gb of data on it. Could this be causing some sort of error based on the 2gb file size limit (the data is NOT in one file though) ?? I know that the size of DVDs are incorrectly reported as 1.99GB, but all of their data still shows up and is accessible. Thought this info might be of assistance.

Hi LoneCrusader,

I have EXACTLY the same problem (3 month old 8 GB Kingston Data Traveller and several years old 1 GB Extrememory USB keys). But I do not have NUSB installed, but the WINTRICKS Driver from this Italian guy: http://www.wintricks.it/faq/usbpen98_2.html (you need to klick thorugh the whole explanation to find the dwonlaod link at the end).

I believe it's a default of the Data Traveller which has to do with different international setups. (At the beginng everything worked fine, like also described by LoneCrusader). But after three month, the Data Traveller gave the same message than the one described by LoneCrusador). I managed to get the key to work again with USBDeview (please google) and recovered my saved files (you need to restart after having used USBDeview), but I wanted to clean the whole thing up and formatted it (after having recovered my saved files with USBDeview), but then the volume was reduced (something like 2 GB less). So I made a THOROUGH scandisk (native windows 98SE tool - takes many hours, because you have the double size, do it overnight). Somewhere in the process there was a question "whether I had a different international language setup". Unfortunately, I clicked to ignore (I am used to this kind of message, because my computer is multilanguage - German, French and English), but I remember that it proposed a solution to this .. can't remember. At the end scandisk said that everything was ok, but asked whether it was a problem, if the key was not labeled. At the very end I saw several (no even a lot of) folders on the USB key, which all had names in (I beleive) Chinese letters. I thought that this was necessary to have them and did not delete them. But now the Data Traveller is not recognized at all anymore. If I click on my removable disk shortcut on my desktop with the data traveller pluged in, it says that there is no USB key ???

However if I use my old 1GB Extrememory, everything is ok !

Does anyone has an idea, how to resolve this strange thing ?

Could it be that the key is not recognized, because it has no label ? I think I will try to repeat the whole procedure again (beginning with USBDeview) and then when it asks for the label, put in the name "Data Traveller" ? Do I need to add "8 GB" to the labeling. Does someone has a Data Traveller can and give me the exact labbeling when the key is plugged in ?

Thank you for your help.

Roger

I run a San disk 8Gig stick with NUSB3.3 with over 2 Gig of data without any problems.

@RogerOver and LoneCrusader:

Before anything, apply KB240075 UHCD.SYS hotfix and see whether that solves your problem.

If that's not enough, post here the VID and PID of your Kingston pendrives, and we'll see what can be done.

ChipGenius http://www.mydigit.cn/mytool/ChipGenius.rar, run under Win2k/XP (not under Win98), is probably the easiest way to find out the VID and PID of your Kingston pendrives, BTW.

Thanks Dencorso,

tried the Microsoft fix and the pendrive was recognized :) , but as an unknown device :( . Tried to reinstall the driver but it does not want to accept the driver (??). What is also strange (and that is perhaps the reason why the driver does not want to install) is that in the Device manager, the pendrive is now shown under USB controllers (crossed out, i.e. showing a sign that somethhing is wrong) and not under Disk drives anymore. Tried also ChipGenius (under WIN 98SE !), but it gives the following message:

Device Name:

PnP Device ID: VID = PID = (Invalid)

Serial Number: (Invalid)

Revision: (Information not returned)

Device Type: Generic USB Host Controller - USB2.0 High-Speed

Chip Vendor: (No match record)

Chip Part-Number: (No match record)

Product Vendor: (No match record)

Product Model:

Tools on Web: (N/A)

Then tested with the old pendrive, same message. So I think I need to find a computer with at least WIN 2000.

It's unrelated. But RLoew has released a freeware fix for the DVD issue. You can get it at his site: RLoew's Software Homepage. As for the pendrive, I'd suggest first you try the fix I suggested two posts above. If it doesn't work, save the 2GB of data elsewhere and accept Windows offer to reformat it. If it gets working again, OK. If not we can look deeper at it. Good luck.

@RogerOver: ChipGenius doesn't work well on 98 anyway, but it even might detect the VID and PID for you, all the same, but it didn't. USBVIEW.EXE v. 5.1.2600.2180, available at MDGx's, on the other hand, works OK under 9x/ME and can tell you the VID and PID, too. Do try it. Unless the pendrive isn't getting even mounted, it should work.

Ok, tried the KB240075 UHCD.SYS hotfix, didn't change anything.

Here's the readout from ChipGenius:

Device Name: +[G:]+USB Mass Storage Device(Kingston DataTraveler 2.0 USB Device)

PnP Device ID: VID = 0951 PID = 1603

Serial Number: 000AEB91BD07F980A50F09D5

Revision: 1.00

Device Type: Standard USB device - USB2.0 Full-Speed (USB1.1)

Chip Vendor: skymedi(??)

Chip Part-Number: SK6281/SK6211

Product Vendor: Kingston

Product Model: DataTraveler 2.0

Tools on Web: http://bbs.mydigit.cn/read.php?tid=4345

While in XP to run ChipGenius, I verified again that the drive was read/writable in XP, no data loss or problems of any kind.

I remember when I first put the new blank drive in Win 98, it showed up with 14.(xxx something) GB free, so I assumed there wouldn't be any problems, guess I was wrong.

With VID = 0951 PID = 1603 and a Skymedi controller, yours is a bona fide DataTraveler, so my suspicion it might be an el cheapo contrafaction turned out to be wrong. However, it may be formated as FAT-32 but may have a XP boot sector and/or Boot Sector (PBR). That might possibly be the problem. You may correct that with MBRFix, take a long breath and delve into cannie's tutorial, looking for info on MBRFix and its use. Also you may search the forums for posts by jaclaz on MBRFix. Give it a try, with MBRFix you may substitute the MBR and PBR, without having to reformat.

NO.

He is NOT trying to boot.

He doesn't need the actual MBR CODE and PBR CODE.

All is needed is MBR DATA and PBR DATA.

If another system can access the filesystem (mind you NOT booting from the stick) these DATA must be correct.

@Lonecrusader

Start a new thread.

Use HDhacker on your XP or dd from Linux and post in a .zip file a binary dump of your MBR and PBR (in hdhacker respectively first sector of PhysicalDrive and first sector of LogicalDrive)

Welcome onboard, jaclaz! :thumbup Your expertise is much needed here!

As for your suggestion to LoneCrusader to start a new thread, it's no longer needed, for I've just split all relevant posts into its own new thread.

Hi,

found this: http://bbs.mydigit.cn/read.php?tid=61480

and this: http://bbs.mydigit.cn/read.php?tid=62781&uid=495034

in the Chinese forum to which the link in LoneCrusador's last thread refers. Translated with Google. But I do not understand (at least not everything), because I do not have the technical knowledge.

At the end of the second link, repair tools can be even downlaoded, but one need to be registered in the forum ... and I do not really know how to log in a Chinese forum :whistle:

You may be luckier on a Russian site ;):

JFYI, the good thing about Chipgenius is that it has a database with links to topics on the (Chinese) Forum:

http://www.boot-land.net/forums/index.php?showtopic=4661

but of course... it's Chinese ;)

jaclaz

Ok, I used HDHacker and got the Logical Drive no problem. (Text output had Kingston in it). The Physical Drive output I'm not 100% sure of, I couldn't select it by drive letter or type, just had numbers 0-9. Numbers 0, 1, 2 returned a sector output. The first one (0) was obviously my primary hdd because i saw some text in the output that obviously was my boot loader. The second (1) I assumed to be my second hdd, and the third (2) output must be the flash drive. :unsure: Hope this is what you needed.
