Hard drive recovery questions

This particular manifestation of a hard drive problem is not classic, but since it could just as easily happen on a classic computer, might as well ask it here. If you think it's inappropriate, please say so. The machine in question is a Mac Quadra 610, which has been running as a fileserver for a 15-machine network for many years. It has an 8GB hard drive, probably one of the first to get into catalogs. It was working OK, but tended to freeze when four people started to transfer 10MB files. So, we replaced it. And now, the hard drive stopped working and we can't get the documents stored on it back. Here is the hard drive problem: it spins up ok (takes about 15sec. and sounds like a hair dryer when it does), and then tries to seek. The heads sound OK for about 1 sec. and then make a clicking noise and stop. It then tries again. Does this mean some servo data has been overwritten or something? We don't want to spend $1000 on recovery, and I thought this might be a good time to try some alternative methods. Would it help if I opened the drive and manually moved the heads? ______________________________________________________ Get Your Private, Free Email at http://www.hotmail.com
