Hi Pluggers,
I have a (rather quirky or obsolete? non-branded) IDE-to-USB converter
connected to my 80GB hard disk so I could use it as external USB HDD.
A couple of days ago, I was copying several GBs of data to my external
drive. After I have copied the files, I tried to unmount it by
right-click --> Safely Remove (I'm using Kubuntu Dapper LTS). It
wouldn't unmount. It sometimes happens to my other USB drives so I
thought it was OK to pull the USB cable anyway.
Now, when I tried to reconnect the external HDD to access my data, it
wouldn't mount. I check dmesg and I see something like this:
[17180236.324000] usb 4-6: new high speed USB device using ehci_hcd
and address 4
[17180236.456000] scsi2 : SCSI emulation for USB Mass Storage devices
[17180236.456000] usb-storage: device found at 4
[17180236.456000] usb-storage: waiting for device to settle before
scanning
[17180247.180000] usb 4-6: USB disconnect, address 4
[17180247.180000] 2:0:0:0: scsi: Device offlined - not ready after
error recovery
[17180247.180000] usb-storage: device scan complete
There was also a message (sorry I forgot to copy it) saying some
reiserfs error code (the filesystem of the external drive is
reiserfs). Could anyone tell me how I could work around this
problem? Or does it mean I've just lost my 80GB forever?
You might be able to recover some data by doing,
# fsck.reiserfs /dev/sda1 (or whatever is your device name)
Then, mount your device.
Ensure your reiserfs-utils is installed.
When you tried to unmount and there was no reponse, you have to wait
until a response is made by the system. There was no immediate response
because your disk was still syncing (transferring data from disk-cache to
physical disc). This is normal because you were copying large amount of
data.
Hope this helps.
