    I bought a Hitachi 500GB bare drive and put it into a acomdata enclosure about a month ago. Yesterday the drive suddenly stopped being recognized by my MBP after I plugged it in! I tried different USB cables, different MBP, and different enclosure. Still no access to the drive!

    This is my Time Machine backup drive, I really don't want to lose all my data. I plugged the drive into a Windows desktop and it is recognized and has the drivers installed when I first plugged it in. But after it did, it still would not show up under devices. What is going on? How can I salvage my drive?

    Phew. Caught a lucky break. Decided to try disk utility after I called Amazon and found I was out of their return policy. The drive had an error so I ran disk repairs and got it sorted. Verified it again and it seems to be ok. Wonder what went wrong...
