 Posted: Mon Dec 24, 2007 10:54 pm Post subject: hdparm cant turn on dma... [SOLVED] |
 |
|
got a new harddrive for storage and hdparm doesnt seem to be able to turn on dma. gives a timer expired and device busy error at boot...
also the read outs are extremely slow (drive is 7200rpm 16mb cache)
| Code: | localhost reksav # hdparm -Tt /dev/hda
/dev/hda:
Timing cached reads: 928 MB in 2.00 seconds = 463.17 MB/sec
Timing buffered disk reads: 12 MB in 3.33 seconds = 3.61 MB/sec
|
my hdparm in /etc/conf.d... (sets dma to on for hdc and hdd, but wont for hda)
| Code: | hdc_args="-d1"
hda_args="-d1"
hdd_args="-d1"
|
| Code: | localhost reksav # hdparm /dev/hda
/dev/hda:
multcount = 16 (on)
IO_support = 1 (32-bit)
unmaskirq = 1 (on)
using_dma = 0 (off)
keepsettings = 0 (off)
readonly = 0 (off)
readahead = 256 (on)
geometry = 38913/255/63, sectors = 625142448, start = 0
localhost reksav # hdparm /dev/hdc
/dev/hdc:
multcount = 16 (on)
IO_support = 1 (32-bit)
unmaskirq = 1 (on)
using_dma = 1 (on)
keepsettings = 0 (off)
readonly = 0 (off)
readahead = 256 (on)
geometry = 16383/255/63, sectors = 160836480, start = 0
localhost reksav # hdparm /dev/hdd
/dev/hdd:
multcount = 16 (on)
IO_support = 1 (32-bit)
unmaskirq = 1 (on)
using_dma = 1 (on)
keepsettings = 0 (off)
readonly = 0 (off)
readahead = 256 (on)
geometry = 19590/16/63, sectors = 19746720, start = 0
|
and finally, errors from my /var/log/dmesg
| Code: | hda: max request size: 512KiB
hda: 625142448 sectors (320072 MB) w/16384KiB Cache, CHS=38913/255/63, UDMA(100)
hda: cache flushes supported
hda:<4>hda: dma_timer_expiry: dma status == 0x61
hda: DMA timeout error
hda: dma timeout error: status=0x58 { DriveReady SeekComplete DataRequest }
ide: failed opcode was: unknown
hda: DMA disabled
ide0: reset: success

I'd say you might have an IRQ sharing problem but I'm no expert. Have you tried PATA for your chipset instead of the old ATAPI/RLL/MFM drivers? PATA sets DMA when appropriate and makes hdparm useless since it doesn't handle serial drives (PATA makes your old /dev/hd? drives appear as /dev/sd?). You might as well post the results of lspci.

It could be a bad cable, since /dev/hdc and /dev/hdd seem to be working OK.
Or it could be a buggy cdrom drive at /dev/hdb sharing the cable with your harddrive at /dev/hda that is causing problems. |

To be sure the disk is dead try it on another machine if you can. It also looks like your motherboard is SATA-capable. You might try a SATA disk if ever this one was dead.
