Check for physical errors on /dev/hda?


Hello, I have to ask - is there any way to check a whole volume for physical errors like broken sectors? In Win you can use CHKDSK, and I got a tip to use fsck on my Ubuntu-machine. But as I'm running ReiserFS, someone told me I couldn't use it because it's an jounarl filesystem.

And even if I try, I get the error "Partition /dev/hda is mounted with write permissions, cannot check it." And I guess I can't unmount it when I've booted my system on it?

Thank you!

go to your lowest runlevel ("telinit 1" I think), then remount your filesystem readonly:
Code:
mount -o remount -o ro /
Tehn try running fsck on it.

You goto the website of your hard drive manufacturer and get their diagnostic utility. You make a floppy, and boot from it. Then, the diagnostic utility will find all bad sectors, which is usually none, and remap them to good sectors. You don't lose any data, and it is fast.
