problems mounting external drive
I am trying to mount my external drive. I think it had a FAT32 partition of 80Gb (the whole drive), but I am not able to.
.
The drive may haver had powering problems (low power supply not a spike).
.
Based on the output to the tried commands, what is happening to it?
.
How can i fix my drive? As I scarcely remember you could use qparted to solve these kinds of problems, but I don't know about the details.
.
How can you fix the drive using knoppix or any other utility for that matter?
.
Thank you
