Linux HD problem

[SpookyEddy]

I get the following error from time to time, I think it has something to do with VIA chipsets & UDMA

"error=0x84 {DriveSeekError bad CRC}"

or something similar.

Any ideas?

TIA

hey spooky,
are you using a ATA100/ATA66 controller?
Also are you using the -X100/-X66 option with hdparm?
that error looks pretty scary...

[SpookyEddy]

Yeah, I am using a UDMA 100 motherboard & a 66 Drive. Just checked the error and it is:

"dma_intr: 0x84 { DriveStatusError BadCRC}"

followed by:

"dma_intr: 0x51 { DriveReady SeekComplete Error }"

I have suffered no problems from this so far but it is starting to scare me

I have swapped both the motherboard & drive (still VIA & UDMA) to different models but still get the errors (using Mandrake8.0).

Any help greatly appreciated

okay!
is this a promise technology controller card (or onboard IC)? If so do you have the promise driver installed as a module or as part of the kernel? I take it makdrake 8 uses kernel 2.4.somthing.

Though this isn't a solution, try:

Disable your DMA in your BIOS (And with hdparm) and see if that fixes your problem.
Be careful with 32bit and DMA as you can toast your drive quickly. I should know.. =]

As previously recommended, make sure you have the (proper) module loaded for your IDE controller, and if you are in doubt, try checking out the manuf.'s page to see if they have any info on there.

Dropped HD to UDMA 33 using "hdparm -d 1 -X 33 hda" and the problem vanished

How do I make my machine keep this setting on reboot?

TIA

hello,
okay to keep this setting add the line
/sbin/hdparm -d 1 -X33 /dev/hda to the end of the file /etc/rc.local, it may be /etc/rc.d/rc.local too, all custom sysinit stuff can go in there.

i have
/sbin/hdparm -d 1 -X66 -S 180 /dev/hda to have the harddrive spin down after 15 minutes, save some heat from being generated.

-S 180 /dev/hdb
