I was running my server on a AMD 2400+ w/ 2 gigs of ram. I installed another HD (Which became the parity) I then was able to purchase Unraid and was able to add another 2 drives.

So I have 3 Sata 500 gig drives and 2 Pata 250 gig drives. After the change I keep getting Errors on the Parity drive... I don't know what is causing it... I can run a check and it would come up with no errors, but then after running the test I would get errors on the parity. Me and my friend (That has Unraid too) decided that it might be my aging hard ware, so I moved it to a newer 939 board. Same ram, just the new mother board/processor and I am still getting the errors. I just checked it again last night (after not getting any new errors in over a week) and now I am getting more errors. I have attached the syslog.... Would anyone be able to tell me what is causing so many problems?

Have you run Memtest?

Have you run SMART tests on all the hard drives?

 

Memtest came back okay....I am going to check the smart as soon as I can

Are you preclearing drives before adding them using the unRAID addon? This is highly recommended because this method will usually weed out bad drives before you get them into your system.

 

I suspect one of these:

1) Bad Hard Drive

2) Bad Power Cable

3) Bad SATA Cable

 

I would run long SMART tests on all drives, make sure you disable spindown before doing this. It can be re-enabled after the tests finish.

 

I had a similiar issue and it was a faulty SATA cable. If your SMART tests complete with no errors, and you don't have any raw errors/reallocated sectors/bad sectors in your SMART logs.. it's probably a SATA cable or power cable.

A couple of these drives are older drives that were "just around".  They might be questionable.  One is from a previously running unraid system that has many hours but no troubles in 4 months of service.

 

This is the second motherboard in this machine and some cable replacements.  I'll talk him into checking out the smart reports and see if there's something obvious with a drive.

Yep... it looks like a bad drive... did go bad until we added another bigger drive  :'( now I need to get another drive in there... did pull the parity out so that it doesn't harm the data. I may be looking for a 1tb drive now.... I just wished I wasn't so strapped for cash.
