Yesterday I upgraded my hardware from a Pentium2 400mhz setup (running freebsd 5.4) to a Sempron 2.8ghz and installed freebsd 6.1 on it (the 32bit version). There are 4 harddisks attached to the IDE-controllers: ad0: 6150MB <Seagate ST36421A 6.01> at ata0-master UDMA66 ad1: 38166MB <Seagate ST340823A 3.39> at ata0-slave UDMA100 ad2: 78167MB <Maxtor 6Y080L0 YAR41BW0> at ata1-master UDMA133 ad3: 38166MB <Seagate ST340823A 3.39> at ata1-slave UDMA100 ad1 and ad3 are the same and both contain important data. After the installation of freebsd I noticed a lot of UDMA-errors: ad1: WARNING - READ_DMA UDMA ICRC error (retrying request) LBA=63 ad3: WARNING - READ_DMA UDMA ICRC error (retrying request) LBA=63 ad1: WARNING - WRITE_DMA UDMA ICRC error (retrying request) LBA=63 ad3: WARNING - WRITE_DMA UDMA ICRC error (retrying request) LBA=63 After decreasing the speed of UDMA (on ad1 and ad3) in the BIOS-Setup, ad1 worked fine, without any errors, but ad3 still produces the same error-messages and is not mountable: (14:51) root (/home/septi) %mount /dev/ad3s1 /test mount: /dev/ad3s1: Input/output error Here the dmesg output: ad3: WARNING - READ_DMA UDMA ICRC error (retrying request) LBA=12063 ad3: WARNING - READ_DMA UDMA ICRC error (retrying request) LBA=12063 ad3: FAILURE - READ_DMA status=51<READY,DSC,ERROR> error=84<ICRC,ABORTED> LBA=12063 g_vfs_done():ad3s1[READ(offset=6144000, length=4096)]error = 5 ad3: WARNING - READ_DMA UDMA ICRC error (retrying request) LBA=63 ad3: WARNING - READ_DMA UDMA ICRC error (retrying request) LBA=63 ad3: FAILURE - READ_DMA status=51<READY,DSC,ERROR> error=84<ICRC,ABORTED> LBA=63 I also replaced the IDE-cable but it changed nothing... Does anybody have an idea? -- everyone's pink on the inside - http://www.nuffinsirius.de
