My computer has 1 main (primary) IDE drive of 250GB. Recently I have added anothe 250GB drive onto the same cable as secondary. At a set time during the night changed files from the primary drive are backed up onto the secondary drive using Find/CPIO. When this backup happens I get many of the following errors in my logs:
Mar 3 07:35:16 dataman1 kernel: hda: dma_intr: error=0x40 { UncorrectableError}, LBAsect=440937085, high=26, low=4729469, sector=232525840 Mar 3 07:35:16 dataman1 kernel: end_request: I/O error, dev 03:02 (hda), sector 232525840 Mar 3 07:35:16 dataman1 kernel: hda: dma_intr: status=0x51 { DriveReady SeekComplete Error }
The values vary but the messages are basically the same. After the backup at 1:00 AM there are no more messages until Cron Daily is run at 7:30 AM when they repeat.
However after that, whatever I do on the computer, there are no more DMA error messages until the next backup. This did not happen at all until the new drive was installed and the backup sessions started.
Both drives are set for UDMA5 (it says in the BIOS).
I don't see why these errors should occur for hda as it is only being read during the backup whereas hdb is being written to but then I don't know anything about DMA.
I tried changing UDMA5 to UDMA3 on hda to no effect. It is now back to UDMA5.
I would dearly like some suggestions from the experts.
