Run Gparted and check Drive sdc. What does it say?

That's why Puppy can't mount it.

When did it last work? What data is on it?

I was going to suggest that you try to mount it in Windows. But if the partition table shows it as Linux, that's probably not going to work.

it was in my former pc which died about 10 days ago. I got a brief message about a cpu failure due to overclocking; then nothing. not even the flash screen. I removed 2 hard drives; one sata and one lde. The sata works via usb, the ide does not. the ide has most of the data on it. The loss of the data is not a major consequence, but it is a major irritation.

Is the data recoverable? Is the drive salvageable?

any ideas anyone?

Adaptor i use : needs usb-storage driver loaded . To change attached drives, usb-storage has to be unloaded to be able to refresh /proc/partitions .
