I recently installed Partition Magic. When I first tried to use it, I got the message:
Init failed: Error 117.
Partition's drive letter cannot be identified
I also got the following information:
Disk error(s) were detected on this drive. See the 'Errors:' list for more details.
Disk geometry error(s) were detected on this drive.
Error#105: Partition didn't begin on head boundary.
ucBeginHead expected to be 0 or 1, not 25.
Error#106: Partition didn't begin on head boundary.
ucBeginHead expected to be 1, not 21.
Finally, I noticed that I apparently have 110 GB, but the drive is supposed to have 320.
Other than that the drive seems to work with any other application that I have.
