had a usb device that when inserted in a windows 7 pc keeps prompting the below. Tried to run elvated dos command to chkdsk g: /f, but it gives msg "cannot open volume for direct access"

Do you want to scan and fix your (F)?

There might be a problem with some files on this device or disc.
This can happens if you remove the device or disc before the files have been written to it.

Scan fix (recommended)
This will prevent future problems when copying files to this device or disc.

Continue without scanning.

Do you have any other flash drives that you can try?  It may be that the drive itself is failing.

Have you tried copying any files off of the drive and formatting it, then putting them back (obviously on a PC where it works)? It sounds like the file system on the drive is somehow corrupted.

it is simply reporting an error on the drive, and you should run the scan to terminate the error
what drive is it?

Try with an external utility like HDD-LLF-Low-Level-Format-Tool or HP's USB Disk Storage Format Tool

http://hddguru.com/software/HDD-LLF-Low-Level-Format-Tool/

And then take it off, put it back on and format it using windows 7. Check from the Disk Administrator that the drive is recognized by the OS.

And if that doesn't work, try it in another 2 PC's if it doesn't work in any PC, then your problem it's the USB.

Actually sometimes the Windows does it even if there is no error on the drive. It simply got a "dirty bit" as you removed it once without using safe removal. So you can easily ignore this message.
Or simply press Fix Now. And see that it says - no error found.

you can also use the fsutil command to query the state of your disk (g being your disk)
fsutil dirty query g:       then type :   CHKNTFS /X G:    

if you want you can then run chkdsk to be sure :   Chkdsk /f /r g:
and finally type fsutil dirty query g:   to check if the bit is cleared

***you best run this from an elevated command prompt

hi,

check inside the usb connector of flash drive for any debris which might be preventing a good connection, (it had happend to me once :) .

 or as noxcho it might just be a "dirty bit".

Does it still ask for formatting?,
has it been recognized in other PC's?,

sorry for the late reply. wanted to try the above steps but the device is now not detectable at all in the pcs, no error message shown now. tried on other pcs still the same. checked with the manufacturer, most likely is the pcb board faulty.
