Hey guys and gals - I've been looking around these forums and google for days now, and am at a bit of a dead end, so I'm reaching out to the community to assist me in piecing this together. I have a few month old MB Pro running Lion. Problem: I have a WD My Passport 1TB with all my music, movies, TV shows, etc... anyone who knows the pain of backing up their extensive DVD libraries knows my struggle. I do not have a back up (I know, I know - I've learned the hard way and I shall repent and sin no more). The drive no longer mounts. When I plug it in, I get the dialog "The disk you inserted was not readable by this computer - Initialize... Ignore Eject" When I run disk utility and try to do a repair, it says: Invalid BS_jmpBoot in block: 000000 Volume Repair Complete Updating boot support partitions as required Error: Disk Utility can't repair this disk. ... etc It's a FAT32 Hard Drive and Disk Warrior laughed at me and spit in my face about it. Windows won't mount it. I used Data Rescue 3 - Quick scan: Nada - Deeps Scan - all the files! The problem is, I used it before and if I recover the files it doesn't keep any of the names. With tens of thousands of files, this doesn't thrill me. It's a last resort. I then turned to Drive Genius 3. Since the drive won't mount, I'm limited on options. I cleaned up the blocks, but it didn't help. The only other logical option I could try would be to clone it over to another external drive, just in case it was a hardware issue. I didn't have much hope, and the cloned drive comes up with the same issue. I also started TestDisk, but it was a bit confusing to me and seemed to want to take several days to scan, so I didn't know if I was wasting my time with that as well. So here I am, at your mercy. Is it the invalid BS_jmpBoot? If so, how do I fix? Google results return little for my situation. Thanks in advance for any direction you can offer. Comfort welcome, too.
