ScanDisk on RedHat Partition


How can I use scandisk on /dev/hda1 instead of c: because it is not in a c or d drive.

Is there a program like scandisk for Linux?

To enter it like that you'd have to open a terminal window, I believe. (Menu/ System Tools/ Terminal)

When I tried it bash didn't recognize it, but that's probably because I don't have that program installed. You can still give it a shot.

Any idea where to download the program?

it is saying the command is not found because of probably:
a) your not running it as root
or..
b) your running it as root but /sbin is not in your path

so in order to run this to solve both circumstances you will have to:
su to root
type the full path
/sbin/fsck /dev/hda

WARNING!!! Running e2fsck on a mounted filesystem may cause
SEVERE filesystem damage.
I take it that means don't use it?

That means don't use it 'then'. You should never run a disk check on a mounted filesystem because of the read-write issues. Umount the drive (if this is your root drive boot up into rescue mode with your CD) and then run fsck on it.

Cool

Most likely it's going to be:
Drop in your INSTALL cd to your cdrom, start up your system, once you get to the point where you "press enter to continue or F1 for help" you press F1, type in rescue and it loads rescue mode. However, that's for a mandrake system, I'm sure RH isn't far different, but the documentation should discuss it.

Something to note:
Your drives are automatically checked with fsck after so many reboots or a given amount of time (usually 20-30 reboots and 50-70 days) to ensure data is not getting corrupted. This is done during bootup when the drives are not mounted.

Cool

You don't have to have /etc/fstab to run fsck. Once you are in rescue mode, be sure your device that you want to scan isn't mounted (you can check with:
mount
If it's listed, umount it with:
umount /dev/hdx)
And then run fsck on it:
/sbin/fsck /dev/hdx

HTH

Cool

In rescue mode? Make sure you aren't in the directory that it's mounted to...

Cool
