My usb drive is stuck in write protected mode after one use (used it to install wins 7 using microsoft tool).
I tried “repairing”, chkdsk, registry mod, ALcor, format, HP usb tool, gparted, all within XP, Vista, 7, 8 and Ubuntu.
Theres no way to use this drive.
I called msoft for support on repairing but they told me this is a known issue on sandisk and to contact them?
Model Sandisk ultra 16gb
