I have just recently installed a Hitachi 1TB hard drive and chose to format it using exFat. All seemed to work fine initially but after a couple of days I can no longer write to the drive. Itt reports the message:
The disk is write-protected. Remove the write-protection or use another disk.
Did your drive come with drive management software? Have you installed any programs that allow you to lock the drive or something similar? Being able to read from a drive that's write-protected is normal behavior btw.
ExFAT switches volumes to read-only on the fly if it detects corruption. This is presumably indicating that MS' exFAT driver doesn't believe your format tool is quite correct.
Thanks all, for the responses. I am not knowingly running any software that could have locked the drive in such a manner. Indeed there are times when I would have liked to have a utility to protect a hard drive by offering whole-disk locking.

Oh! Well that's probably it then. As the drive's first useage I was carrying-out a large file transfer process of some 500MB during which the PC hung mid-way. I could not gain keyboard or mouse access to revive it so it was hard reset. I can see ther logic in locking the drive under crash scenarios but what is one supposed to do following such a lock Does Microsoft offer an exFat suite of tools?
I just built a new pc and I have two data drives where are 1 TB WD hard drives. Each time I boot up it is a crapshoot if the drives will work or not. They are recoginized by windows just fine but someones the first drive is listed as write protected, sometimes just the 2nd one, sometimes both, and sometimes both are fine. I have Windows 7 Pro 64 bit so I didn't know if that had anything to do with it. The main op sys drive (Which is a WD raptor drive) always works fine however.
