server is killing my harddisks


If have a Tyan-server with linux os isntalled, CENTos. Everytime I try to install linux my harddisks get corrupt and have to be replaced. Tyan cannot find anything wrong with the motherboard so they say its not their problem.

Does anybody know what can cause these problems, it already distroyed 6 harddisks?


Best regards,

Jasper

are you using the intergrated Hardware raid controller or using
linux MD software Raid?

if the former maybe CENTOS doesnt support your raid controller 100%%


check the website of the maker of your raid controller
or try the linux MD software raid.

Hi,

One of my machines has a Tyan motherboard (S2668 Tiger i7505) with 3 western digital (200Gb) disks attached. Haven't had any problems, but I don't use the raid option. It currently runs (B)LFS and the first few weeks it ran Slackware.

carl0ski could have a very valid point if you use (hardware) raid.

HI,

No, I'm not using a hardware raid. The first hd's where distroyed without software raid, later on I installed a software raid, that just saved me some data loss when one of the hd's died.

Today I was again trying to get the server to work, but today I plugged the server in a socket without earth. I know the server should be connected to a socket with earth but it was just for a moment. When I started up the server the second hd was not seen by the BIOS. This should not happen I think even when I don't have earth connected. I think this shows that something is wrong with the hardware.

After that I connected the server to a socket with earth and than the hd was seen again by the BIOS

What do you all think about this?

Regards,

Jasper

Hi,

This does not look like a problem that is OS related.

Did you build this machine yourself and/or added hardware parts yourself? I'm asking because it could be that one part (or more, but the motherboard and HD's comes to mind first) isn't grounded correctly/isn't connected correctly.

If you bought it pre-assembled, let the store that sold you the box have a look at it, if you build it yourself re-check all the parts (cables/connectors/boards inserted correctly, screws missing/loose etc.).

Also: Do you hear any odd beeps when starting up your box and/or are there any strange BIOS POST codes (there's a LED indicator on my Tyan board that shows these codes, take a look at the Tyan user's manual for details).

Hope this helps.

i need you to elaborate

are your file systems getting corrupted or are the drives getting physically damaged?
aka a faulty power supply made two of my HDD's literally smoke and spark.

FaULTY ram, faulty CPU, overheated RAM of CPU can result in data and file system corruption


so far there is little possibility this is a software issue

The drives are getting physically damaged according to the seagate and maxtor tools and need to be replaced.

Jasper

damaged sectors ? bad heads?

i have seen damaged heads caused by
faulty power supply or other device disrupting the power cycle
faulty fan, CDRom, etc


however it isnt possible for a computer to damage individual sectors without wear/tear/age/falling

Theoretically
WD Maxtor Seagate
have different number of heads/sectors/LBA blocks
and will be recognised differently by the raid controller.

You must use all Maxtor or all WD in you hardware raid array otherwise you will get bad sector errors since they dont line up equally.
eg my WD is 186GB
my Maxtor is 197GB
my Seagate is 190GB

put the suspect disks in 1 at a time do a full sector scan again.
fsck.ext3 -c -f -y -v
