usb drive wont mount (input/output error)
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
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.
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......'
