How to run fsck or e2fsck (solved)

[ICMike]

I have an external backup drive (/media/Iomega500GB/ or dev/sdd NTFS file system) This is not my boot drive.

Can fsck or e2fsck check an NTFS formatted drive? This drive was a gift and even though I reformatted it, I'd like to verify its integrity. I know I can do this in Windows but want to learn something.

Can fsck or e2fsck check an NTFS formatted drive?

Not according to this: http://linux.die.net/man/8/e2fsck

Try GParted -- right-click the partition and see whether it offers a check function (i.e. I don't remember).

If that happens not to work, you might try this:

Install the package "ntfsprogs", then use the command "sudo ntfsfix /dev/xxxn" to scan an ntfs filesystem, where xxxn is the device to scan (such as sda1).

However, since NTFS is a Microsoft proprietary system, the method of choice would be this: http://kb.wisc.edu/helpdesk/page.php?id=5097

Thanks. gparted has the option to "check" an NTFS partition or device once its unmounted. It only ran a couple seconds and provides a nice report too.
