usb drive wont mount (input/output error)

[edzillion]

As usual I went ahead like a blunderbus and did lots of things I had no idea what I was doing.
Anyway I had a problem accessing the internal drive on my laptop and was getting the same error as the OP:

Unable to mount device
Error org.freedesktop.Hal.Device.Volume.UnknownFailure

So tried to mount it various ways and then used the command:

mount -t ntfs-3g /dev/sda1 /media/sda1 -o force

which worked fine.

Step 2:

Tried to get the USB hard drive to be recognised so I could copy the data off the drive, so again:

mount -t ntfs-3g /dev/sdb /media/sdb -o force

which worked. Copied all the information off the internal drive and then put the usb drive into my windows machine (didnt dismount). When added it recognises a usb mass storage device but doesnt appear in my computer. Also I tried remounting it in knoppix but I get the error 'input/output error. NTFS is either inconsistent, or you have hardware faults......'

any ideas?

Try to reformat the USB drive, this time don't use NTFS. If you want it to be read/write by both Linux and Windows, use FAT instead.

CAUTION: reformatting the drive will erase all of the files on it. Don't do this if you need to recover more of the files.
