I have a hard drive, and when added, it will time out during parity checks and causing random parity check errors. I tried it in another hotswap bay and it still times out. The only thing I can think of is that the drive is bad but it seems to do everything correctly other than parity check. It will even do a parity sync, but as soon as I try to verify that sync with a parity check.. it times out.

 

I just transfered 1.5TB of data off of it, verified the data with CRC checks, and found no errors and it didn't time out. I have to cold boot, disconnect the drive, and plug it back in to get it to redetect the drive. Even restarting doesn't redetect the drive after it times out.

 

1) Smart is FINE.

2) Power Supply is not the issue, I tried adding another drive of the same model.

3) Passes SMART long test.

4) Cables are not the issue, I tried 3 different power and sata cables, and 2 hotswap bays with 2 different SATA controllers.

What were the pre_clear results?

Any chance this was a Seagate 1.5TB 7200.11 drive? ie, The ata15: hard resetting link was something I was seeing as well.

There were no errors on it. I'm going to preclear it again and see if anything changes.

1.5TB Western Digital Green (EADS)

 

I have 12 greens in my system, the other 11 are fine.

I setup an RMA for the drive.. but i'm still puzzled because the drive seems fine, and i'd hate to send it in for a replacement just to have the new one do the same thing. I don't see any other possible hardware issues though, everything points to the drive.

I'm not sure they're related then, but I did RMA the drive(s) based on a recommendation from Lime Tech and I wound still seeing the same problems with new drives. I wound swapping ALL of them for WD20EARS because Tom suggested it was a Seagate firmware problem.

 

Like you, I'm still puzzled by it. I haven't seen the problems I was seeing before with the WD20EARS but I'm seeing bug crashes that is really annoying me now.

 

ETA: Maybe you email Lime Tech too...if they're related problems it tells me it isn't the drives that are at fault.

I just tried to preclear the disc again and it failed almost instantly. Going to RMA it.

 

My logic is that the drive can handle reads and writes of around 50MB/s (transferring files off the disc, parity sync, etc). But preclearing (90MB/s) and parity check (80MB/s) is causing it to fail.
