Hi,
I've got a big problem concerning my second hard drive. Sometimes, let's say
once a week, my Linux unmount an hdb partition with this message:
>>================================
EXT3-fs error (device hdb5): ext3_journal_start_sb: Detected aborted
journal
Remounting filesystem read-only
journal commit I/O error
__journal_remove_journal_head: freeing b_frozen_data
__journal_remove_journal_head: freeing b_committed_data
<<================================
fsck.ext3 can fix the problem, but it writes many errors like this one:
>>================================
end_request: I/O error, dev hdb, sector 22558875
hdb: dma_intr: status=0x51 { DriveReady SeekComplete Error }
hdb: dma_intr: error=0x40 { UncorrectableError }, LBAsect=21791542,
sector=21791483
ide: failed opcode was: unknown
end_request: I/O error, dev hdb, sector 21791483
hdb: dma_intr: status=0x51 { DriveReady SeekComplete Error }
hdb: dma_intr: error=0x40 { UncorrectableError }, LBAsect=21791511,

end_request: I/O error, dev hdb, sector 21791491

sector=21791499
ide: failed opcode was: unknown
end_request: I/O error, dev hdb, sector 21791499
<<================================
I've read it's a DMA problem. Here's my hdd params:
>>================================
# hdparm -i /dev/hdb

<<================================
This automatic read-only remount is quite annoying. What can I do?
Bye,
Belbo
