I'm getting lots of read errors on the second=20 disk. They appear on the console as: (ada1:ahcich1:0:0:0): READ_FPDMA_QUEUED. ACB: 60 00 00 6b 02 40 00 00 00=20 01 00 00 (ada1:ahcich1:0:0:0): CAM status: Uncorrectable parity/CRC error (ada1:ahcich1:0:0:0): Retrying command dmesg: ACS-2 ATA SATA 3.x device ada1: Serial Number XXXXXXXX ada1: 600.000MB/s transfers (SATA 3.x, UDMA6, PIO 8192bytes) ada1: Command Queueing enabled ada1: 1907729MB (3907029168 512 byte sectors) ada1: quirks=3D0x1<4K> I've replaced the disk and the cable without improvement. Unfortunately,=20 I don't have a second CPU board to try. Is it possible that the board can't keep up with the data coming from=20 the disk? If so, can I try slowing it down somehow? Any other suggestions, please? Thanks, =C2=A0=C2=A0=C2=A0 Graham
