Yikes! I had (yet another) freeze while attempting File Synchronization (w/ control panel, Sys 9.0.4) on my Apple 7300. After I force-quit, my boot hard drive (and all its partitions) disappeared.

I've unhooked all my SCSI devices, and can still only start up from a CD. I've not had any luck mounting the drive with any of my utilities. Disk First Aid can't find it, neither can Disk Warrior or Norton. Drive Setup indicates there is "no disk" on the drive, and SCSI Probe reports it can't find a valid driver.

Is there any hope for it? Thankfully, most of my work files are on another (internal) disk, but there's still so much information and time I'd loose starting over on this disk.

If possible, please let me know by direct email ( dfeather@aol.com ) if you post helpful information here.

Thanks so much,
Dan Feather

Cut connection of your HD, start computer from CD. Set "Start-up disc" to this CD (I had somthing similar once and only holding down the C-key at startup didn't do the same). Turn off computer. Connect HD and start again. Then run Disk Warrier. Of course, the CD must contain the Disk Warrier extension in it's system folder.
If you have access to another Mac, take your HD off your computer and try to mount (and repair) in the other one

Thanks for the suggestions. But I haven't made any progress. In addition to trying what you said, I even mounted the drive in an external box. I've changed the ID number, tried it terminated and unterminated, inside another computer, the original computer, power supply activated before startup, after startup . . . Agggghh!!!

I have run every version of every utility I have, and never have I been able to mount it or find any volume information on it.

I finally decided there was no way I was going to salvage anything, but then I realized that I can't even format it! Drive Setup reports there's "no disk" in the device; SCSI Probe returns a "sense" error of -7932 when it tries to mount it, and even FWB's Hard Disk Toolkit can't do a thing to it, saying there are no volumes, and, when I try to create a new volume, it says the device is not ready. The "info" FWB returns indicates there are no blocks on the device.

Is there nothing I can do with this drive now but use it as a paperweight? This is really terrible . . . Bad enough to loose data, but when I can't even reformat it, what am I to do??

Any advice appreciated.
