When the "TAK" sound became more frequent, I got scared and copied everything to another drive. A subsequent check showed a damaged (and unrecoverable) partition, so yes, the drive was failing. Lucky me, I had enough time to backup. Even if your drive is failing (and it seems it is), trying several times could perhaps give you a "one time lucky shot", when you can recover something (unless there's something broken in hardware). > Disk Utility and Data Rescue > (DEMO) can't recognize.

Did you check if the drive is seen in System Profiler? Have you tried Drive Genius? It seems quite powerful. > Have in external Firewire/USB 2 case with Single/Master pinning. Having it connected internally is usually better for testing/recovering. When using an external case, go for FW and avoid USB (slower, less reliable) Did you try recovering it while connected internally? > Cable select make any difference? Don't think so. And the only time I used Cable Select (in a G4), I got hard disk troubles, so I'd avoid it. > Surprisingly, > perhaps, the only program I have success with in grabbing a drive that > no other could was the old Norton Disk Doctor under SystemWorks. I agree. Sometimes Norton (under OS9) did wonder. Can you still boot in OS9 to try it? -- You received this message because you are a member of G-Group, a group for those using G3, G4, and G5 desktop Macs - with a particular focus on Power Macs.
