A simple way to wipe the 1st MiB of data is using the dreaded dd command (actually this is what mkusb does, but its UI provides warnings and better protection against mistakes). With the use of mkusb utility I successfully recovered the flash drive back to normal.īut of course you can do the same without any utility, just from the linux command line. But if the drive works under linux, it should be no problem to make the backup before.) (However the drive must be re-formatted afterwards and the data is lost. This cleaning should help to bring the USB flash back to normal. (For Ubuntu, there is a good help page here.) Among others, one of its functions is to wipe the first megabyte (MiB) of the drive. There is a wonderful and reliable linux utility named mkusb, the "tool to create boot drives". So what is needed is a sort of clean-up, which would wipe the remaining traces of the other (iso9660) file system.

While linux does not care about these leftovers, Windows are probably more strict when checking the inserted flash drive, and they refuse to access it. My understanding is that some live linux installers format the flash drive to an iso9660 file system, and re-formatting the drive back to FAT32 does not fully remove the tracks of the previous file system. For linux, on the other hand, everything worked without problems. Also formatting the drive was not possible in Windows. After I formatted it back to FAT32 (in linux), Windows could not access the drive, though they detected it. I ran into this problem several times after I had used the flash drive for a live linux installation. I am rather late with my answer, but I believe people still come across this problem, so it might be useful. And is there any way to fix it? If yes then how? What can be cause of this? Given that the device is working okay in Ubuntu, I assume that the hardware itself is not damaged.
WIN TO FLASH DRIVER
I read that it might be a driver problem. In addition, I tried to plug this flash drive into freshly installed Windows 7 圆4 Ultimate. FYI the filesystem was NTFS, reformatted as FAT, so that's hardly the issue. However, under Ubuntu 10.04 on my netbook, the flash drive is fully operational: I could easily back up data from it, format it (however formatting did not help to get it running on Windows).
WIN TO FLASH INSTALL
Windows 7 also fails to find and install drivers for Unknown Device.
