 Posted: Sat Jan 21, 2006 2:16 am Post subject: Hard drive seizures [SOLVED] |
 |
|
Recently my PC has started locking up. It seems to be a disk problem: the drive light comes on and stays on, and any running processes that need disk access hang, while those that don't appear to keep running.
This seems to happen primarily when the disk is writing big files: e.g. while doing portage downloads or running VMWare. I find that I can go a week with no problem, then it will happen three times before I can complete a large download. (E.g. I start a download, after a minute or so the PC locks up, I reboot, resume download, it gets a bit further, then hangs again... eventually I get the whole file.). Then it's fine again for a few days.
I wouldn't be surprised if it's a dodgy disk, since I sent this thing back to the manufacturer once before and they actually repaired it and sent it back. (Who repairs disks? I thought they would just send me a new one.) But I don't have any real evidence.
The disk is a 200GB Seagate SATA. I patched my kernel to enable support S.M.A.R.T. for SATA disks, and this works fine but none of the tests I do show any problem. I don't know what else to do. Any idas?
I'm running kernel 2.6.14-gentoo-r2 and amd64 arch. Mostly the disk is formatted to ext3, but there's also a swap partition and a small ext2 boot partition.

Thanks for the tip. (I went overseas for two weeks; just got back.)
I ran the Seagate diagnostics and the disk passed a Full Surface Scan with no problems. I rebooted into Linux, tried to 'emerge update', and the disk locked up halfway through.
Any other ideas? It's very alarming to have a Linux box that crashes all the time... so Windows-like. *shudder* |

Cooling. Is there any airflow around that disk? Overheating is a good and common way to kill disks.  |

Thanks for the reply.
I moved the hard disk away from the other disks and left the side of the PC case off to provide maximum air flow. Still the disk seized up halfway through downloading a 90MB file.
Any other ideas? |

By the way, I've noticed that the disk seems to handle READING just fine. I can 'cat' a 700MB file with no problems. It's only WRITING large files (bigger than 10 - 30MB) that leads to lockups.
Neither the S.M.A.R.T. and Seagate Tools tests seem to write large files--in fact I'm not sure they test writing at all; they just seem to test reads.
I would love to find some evidence that it is the actual disk at fault and not Linux, but can't think how to do this without, say, wiping the disk and installing Windows on it. |

I wrote to Seagate Seagate Tech Support and they replied:
| Seagate wrote: | Hello,
please make sure of the drivers for you Sata controller. make sure
the drivers are for your sata controller and not RAID. Refer to your
motherboard manufacturer.

What does this mean? I think this is my SATA controller:
| Code: | $ lspci
...
01:0d.0 Mass storage controller: Silicon Image, Inc. SiI 3512 [SATALink/SATARaid] Serial ATA Controller (rev 01) |
and I have support enabled for it in my kernel:
| Code: | | CONFIG_SCSI_SATA_SIL=y |
... so... what should I do? |

check out your hdparm settings... (hdparm -i /dev/hd?)
also anything in dmesg when this happens?
On my pata drives, it was auto falling back to no dma and was just whacking my computer. I setup hdparm to roll back to udma3 on bootup and no more issues (I've got the drives in trays with long cables, so they can't run full speed without crc errors. |

Thanks for the reply. Everything looks fine. DMA appears to be enabled. And the disk is nice and speedy 99% of the time... until it locks up. I have tried leaving it for a couple of hours to see if it comes back, and it doesn't.
I don't get any messages in dmesg or /var/log/messages when I run these commands.

| Don't want to speak too soon, but I upgraded my mainboard's BIOS (which also reset all BIOS settings to default) and I haven't had a lockup since, despite downloading big files. Fingers crossed... |

Two weeks with no lockups... I'm calling it a fix!  |
