fsck.ext3, badblocks, memtest86+
Maybe you want to know how we examined RAM problem in the previous post. We have tried several ways to do it:
- fsck.ext3 -c, ex: as root run fsck.ext3 -c /dev/hda6, it will check ext3 filesystem in the logical partition number 6 with badblocks checking.
- badblocks, this is separated program used for searching badblocks in a storage device. The recomended way to run this app is by using option -c via fsck.ext3. But if you want to run it directly never mind, it’s your choice, I’ve told you. Just run: badblocks -n /dev/hdaX for non-destructive mode instead of running it with option -w. You can’t combined the options in a single command.
- mem86test+, this program which usually shipped with your distro, used for checking memory errors, provided in bootloader options, GRUB menu or kernel parameter passed to LILO. The program is really nice and did the job well.We knew we have a problem with our “extended” RAM is from mem86test+. We just booted Knoppix 5.1.1 and gave a parameter memtest, the program will check the memory errors and yes, we found so many errors with the red indicator. But if we unplugged the additional memory and check it again with the same program, the errors gone.
You may have a question like: how do we do if our partition isn’t ext3? the answer is use fsck.reiserfs and read the manual.
By the way, why we aren’t use Kuliax to do memtest? the answer is simple, we didn’t ship memtest86+ in Kuliax 6.0 but we will include it in the next 7.0!
