I've done some searching, and it appears that OS X should be able to read an NTFS formatted external drive. I've been using various Mac notebooks for the last several years, and finally decided to ditch my Windows box for one of the new Core 2 Duo iMacs. It has the latest version of OS X, because it just came out last week. I'm trying to hook up a known good drive through one of the USB ports on the back of the iMac. The enclosure is USB 2.0. It gives me an error saying "Disk Insertion: The disk you inserted was not readable by this computer" and I have Initialize, Ignore, and Eject as options. It shows up in Disk Utility, but refuses to mount. I'm sure it still works, because I can see the drive and files when in Parallels. Ideally, I'd like to be able to access it with OS X directly, but I'd settle for just getting the files off of it onto my iMac, so I can reformat the disk in FAT32 or HFS, and then put them back on. I'm open to creative solutions. Any help would be greatly appreciated.
