The partition was not cleanly unmounted, you need to run chkdsk on the partition from Windows (if you have windows)

To do it in Ubuntu. First install the package ntfsprogs, then run the command ntfsfix

The ntfsfix program fixes some errors and not others. It marks the filesystem as needing checking by Windows. Because there isn't a fsck.ntfs, the ntfs filesystem isn't a good choice for use in Linux. If you don't have access to a Windows installation, don't use it.

You might want to read the kernel messages in /var/log/messages and search for messages pertaining to the usb device. Also, maybe try a different USB port. If you have a usb 1.0 device and a usb 2.0 device plugged into ports that are on the same internal hub, I can imagine that might cause problems. Another issue is power. Sometimes one group of ports can supply more power than the other. On my laptop, the ports on the left hand side work better for my wireless mouse's receiver.

A physically damaged port or cable could also cause intermittent problems. Pay close attention to the ends of the cable. Does it seem bent or spread out? Does the cable plug in snuggly, or is it very loose?

Run this to find out which disk/partition refers to your external drive.

Code:

$ sudo fdisk -l

You should find something like this:

Code:

Disk /dev/sdb: 80.0 GB, 80026361856 bytes
255 heads, 63 sectors/track, 9729 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x6909f232

   Device Boot      Start         End      Blocks   Id  System
/dev/sdb1               1         9729   80713463+   7  HPFS/NTFS

The command line would be something like:

Code:

$ sudo ntfsfix /dev/sdb1

Check out jschiwal's post above, like he said ntfsfix it does not fix every problem. It just does a basic reset for unclean shutdowns.

If you have a Windows box, I'd suggest trying chkdsk from there. If you don't have a Windows box, you really shouldn't be using ntfs.

It would be appreciated if you would use better English in your posts. It's more difficult trying to analyze the problem and propose solutions when one's mental energy is occupied trying to decode the question.

Try mounting the NTFS partition read only. You may be able to move the data you need from this drive to another.
