Strange. My pendrive won't mount anymore
 

Very strange

My pendrive works under Windows, but I can't mount it on my Slackware at home (but the automount system at my Suse at work mounts it fine).

When I try to: mount /dev/sda1 /mnt/hd, I get:

mount: /dev/sda1 is not a valid block device


And when I try: mount /dev/sda /mnt/hd, I get:

mount: you must specify the filesystem type

And my kernel returns:

Sep 25 23:00:52 MACHADO kernel: sda: Unit Not Ready, sense:
Sep 25 23:00:52 MACHADO kernel: sda: I/O error: dev 08:00, sector 0 (twice)

and then

Device 08:00 not ready.
Sep 25 23:00:52 MACHADO kernel: UMSDOS: msdos_read_super failed, mount aborted.

I tried mount -t auto, -t vfat, -t umsdos, but none of them seen to work

could you post the output of sfdisk -l

Wow, I didn't know that command, and it seens that there really is a problem with my pen, here's the output:

Disk /dev/sda: 1023 cylinders, 64 heads, 32 sectors/track
read: Input/output error

sfdisk: read error on /dev/sda - cannot read sector 0
/dev/sda: unrecognized partition table type
No partitions found

Disk /dev/sdb: 1009 cylinders, 32 heads, 61 sectors/track
Units = cylinders of 999424 bytes, blocks of 1024 bytes, counting from 0

Hum... very strange indeed...

or perhaps grab all the data off of it, and reformat

already done that, didn't work :-/
