hard drive errors

[Craig Pemberton]

Hello everyone,

My computer has been freezing up quite a bit lately, especially during long compiles. Strange things happen with large copies or file decompressions. I recently moved to Houston, and it has been stuffy so maybe it's overheating. I moved my hard drive to a shorter IDE ribbon and opened the case and one of those things seemed to help but now my case is back together and crashing.

Here is a script I used to pull the relevant information out of the logs concerning my hard drive. What can I do? Is this a simple issue or am I looking at a sudden loss of all my data?

Thank you.

Hello Craig

Seems to me that your Harddisk is defective maybe because of you moved it - i suggest you backup important data you have, and than do some checking on the drive...

you could try doing fsck which checks for problems on the filesystem and tries to fix them , BUT:
it is slow and you have to do it when all you filesystem is unmounted ( use a rescue cd or something)

I have done fsck on my ext3 and e2fsck on my ext2 and fsck.vfat on my FAT32. They seem to find errors fairly often. Is this common?

How would I check my swap partition?

How would I figure out which sectors map to which partitions of my hard drive anyway? Can't I turn those sectors which are bad 'off' somehow?

I guess mainly what I don't know how to figure out is if this is *really* a hard drive problem or something else. Right now I'm a broke college student and don't need to be buying another hard drive if I don't absolutely have to.

Thanks!

Its not common, usually linux is very stable and fsck rarely needs to be used.

i dont think you could check a swap partitions, anyways its being rewritten every time the linux boots

how could you mark bad sectors using linux is a good question , i dont know (the windows scandisk does that but its irrelevant for us )

if those problem and errors in fsck arise again it is most probably a defective drive
