Q: What are these hard drive error messages dmesg?

ata1: translated ATA stat/err 0x51/04 to SCSI SK/ASC/ASCQ 0xb/00/00
ata1: status=0x51 { DriveReady SeekComplete Error }
ata1: error=0x04 { DriveStatusError }

A: Many times these errors indicate drive failure in the near future. If you are unfortunate enough to witness these messages there are a few steps that can be taken.

First: Begin backing things up starting with the most critical. If the drives are dying, the less disk activity there is, the longer it may live so choose wisely.
Second: If the drives are still running after backing up essential files, it's time to check if the drives truly are failing. To do this, install sys-apps/smartmontools if you haven't already. After installing them, check IDE (hdX) drives (where X is your drive letter) by
Code: Select all
```
smartctl -a /dev/hdX
```
For SATA (sdX) drives, try:
Code: Select all
```
smartctl -a --device=ata /dev/sdX
```

Third: If no errors are reported, you may have escaped drive failure and a simple kernel config option may cure the errors. For kernel versions >=2.6.19, try enabling:

Code: Select all

CONFIG_IDEDISK_MULTI_MODE:
If you get this error, try to say Y here:

hda: set_multmode: status=0x51 { DriveReady SeekComplete Error }
hda: set_multmode: error=0x04 { DriveStatusError }

If in doubt, say N.

Symbol: IDEDISK_MULTI_MODE [=y]
