I have a Vista64 Ultimate machine with 4 phsical hard drives.
Seemingly ar random, the OS slaps write protection on an entire disk. I can go away for a coffee and come back BAM a key disk is write protected.
I am logged onas administrator, the attributes fot the disk show that it is not write protected, but every time I try to write to it I get a "write prtotected" dialoge box.
If I r reboot perhaps 3 times it clears and I am OK for a couple of days.
Any cures without multiple re-boots?
