In the past, I've found that a broken mp3 player's hard drive can come in handy as an external if you can find an adapter/enclosure to fit it. Recently, my friend's iPod ended up broken, so I decided to try it with the HDD that was in it. HDD: toshiba mk8010gah So here's the issue: I tried erasing/formatting the drive with Windows 7, XP, and OS X. XP doesn't even list the drive in the disc manager, but still lists it under hardware manager. Windows 7 lists it in hardware manager, but can't format or erase. OS X recognizes it and sees its size/model etc, but can't erase. I've done a lot of digging, and read that even HDDGURU's Wipe Tool and Atola's HDD Capacity Restore aren't effective. Apparently Apple has put an HPA/DCO on the drive, and then special firmware... and the only way to remove this is with special hardware. Any ideas or thoughts? I'd like to find a hard drive firmware repair tool that I can buy online, but it seems most companies only list product info on their sites (no online buying option).
