Hi,
I'm using an external eSATA / USB / Firewire 2x1T RAID from WD in RAID1
configuration for backups with ext4 under 2.6.28.7. I've got a couple of
problems with it before, and today a backup aborted with error messages
below. Actually, those errors come from two backup attempts: the first one
over NFS, and the second one locally. The system is one year old with an
Intel chipset:
00:00.0 Host bridge: Intel Corporation Unknown device 29b0 (rev 02)
with a Core-2D 2.66GHz, so, it does have 3Gbps SATA, and below the driver
drops down to 1.5Gbps.
The problems I had before with the disk were, that it has a badly built
eSATA connector, the connector doesn't sit firmly enough in it. So, the
main question, I guess - cann errors below be caused by that? I think,
I'll have to contact WD for an update, or use Firewire for now...
Thanks
Guennadi
