irq/DMA timeout på ny disk.

Jeg får følgende på en ny disk (1mdr gammel.)

hdc: dma_timer_expiry: dma status == 0x61
hdc: dma_intr: status=0x51 { DriveReady SeekComplete Error }
hdc: dma_intr: error=0x40 { UncorrectableError }, LBAsect=2621519, high=0, low=2621519, sector=2621456

Den fortsætter med den fejl sålænge maskinen er tændt.
Er disken kaput, og/eller kan jeg nøjes med evt. at disable noget i bios?

På forhånd tak.
