and here is why. I had a hard drive that just stopped working on a windows PC the data got corrupted or something because the computer froze and when I restarted it..it couldn't read the hard drive. I tried formatting this drive with the 98 start up disk, by putting it in a windows comp as a slave, and useing maxtor disk utility tools. Nothing seemed to work. Everything would just sit there forever and say it was formatting the hard drive, but the hard drive wouldn't be doing anything at all. I decided to put it in my mac as a slave just to see what would happen. My mac brought up the disk utility and I told it to erase the drive. It had it fully working in 5 minutes. I think I'm ready to make the switch now.
