I have a samsung 40GB drive that appears to be "locked". Any files that I save to it are gone the next time I start up the computer. Likewise, any files I delete reappear the next time I startup the computer. I have tried to reformat the drive, but after completion and rebooting the drive is untouched. The same happens with using fdisk to try and remove the partition. I have run scandisk and NDD, both say that they have found and fixed an allocation error as well as a problem with the boot area containing invalid information about the amount of free space on the drive. But after rebooting and rerunning these same problems are reported again and again. Is it possible that something has locked this hard drive?
