I ordered a bunch of 1GB usb drives from a. Most of them work just fine, but a couple of them won't let me format them because they are 'write-protected.' There is no write protection switch on the device. I have exhaustively tried the following: • Windows format: 'The disk is write protected' • HP USB Disk Storage Format Tool: 'Device media is write-protected' • Changing registry key HKEY_LOCAL_MACHINE SYSTEM CurrentControlSet Control StorageDevicePolicies to 0 • diskpart clear attributes readonly • diskpart clean: 'Diskpart has encountered an error: The request could not be performed because of an I/O device error. See the System Event Log for more information.'

Is there any way to get more information about the problem? One more important thing: Do not use those defective sticks anymore! You might be tempted to partition the stick to use the intact area (not sure whether that would make much sense on a 1GB stick anyway), but the wear-leveling of the flash controller will, over time and depending on write cycles, try to utilize all flash memory cells to spread wear evenly over the whole flash. You will have no control over which Flash cells are written, no matter how you might partition the stick.

(If the stick would be the cheapest of the fakes without any wear leveling, then this would be even worse.) – Dec 17 '13 at 7:16 4.
