Today I found this that at my /var/log/message (kernel 2.6.10):
Dec 26 21:35:14 s1 kernel: ata5: status=0x51 { DriveReady SeekComplete
Error }
Dec 26 21:35:14 s1 kernel: ata5: error=0x84 { DriveStatusError BadCRC }
ata5 is md raid1 with ata6, both are sata drives connected to a promise
SATA controller.
at /proc/mdstat, the raid 1 is still active with "[UU]"
Is my raid 1 safe and should I replace the "ata5" drive? Also, why the
raid-1 still up with status "[UU]" ?
Thanks

BadCRC is usually cable noise. The kernel will retry such an event
several times, then fall back to PIO and try that before it gives up.

Are you sure? This is Promise SATA driver not IDE one.

In other words: The data to disk and from disk is consistent, so the data is
safe.
