    Hey everyone! I'm a recent PC to Mac switcher. I bought my first Mac yesterday morning and am thrilled with it. :D

    On my PC, I had an IEE (I think!) type hard drive with a large collection of photos and music, and I didn't want to spend the time tediously switching every file from my PC to my Mac. So I took out the hard drive with my music and pictures from my PC, and bought a hard drive case. Which was fantastic, until I realized that it didn't work on my PC or my Mac. Finally, I fiddled around with some jumper plugs on the hard drive, and the PC started to recognize it. The PC now works with it, but not the Mac.

    I plugged it into the MBP, and went to Disk Utility.

    The hard drive isn't mountable and it's telling me:
    "Verifying volume disk1s1

    Verify volume failed: Unrecognized Filesystem."

    What does that mean? All that's on the disk are pictures and videos, I believe. If anything else is on there, should I just clean it off?

    Thanks guys! :)

    It means that the Mac can't read the file system that the drive is formatted in. It's probably NTFS, which you can read on your mac with a variety of programs.

    IDE drive, sorry!

    Yes, I formatted the whole drive and rewrote it in Mac OS X (Journaled.) Does it make a difference if it's journaled or not? It works beautifully now.
