有哪位高手告诉在下努力方向，或则干脆告诉我怎么解决

------解决方案--------------------
我注意到有如下信息，我以前移植SATA硬盘的驱动时也碰到过分区表读不了的情况，后来发现是字序问题。对你的问题，没有更多的信息，无法提供帮助。你何不一步一步地缩小范围？找到出错的代码在哪就好办了。
Partition check:
/dev/scsi/host0/bus0/target0/lun0: I/O error: dev 08:00, sector 0
I/O error: dev 08:00, sector 0
unable to read partition table
sda : READ CAPACITY failed.
