Looks like your replacement disk is no good, the SATA port is bad or other issue. I am not sure what SDB FIS means but as long as you keep getting that error, don't expect the drive to work correctly, I had a drive that did a similar thing (DOA Raptor) and after I got the replacement it worked fine. However, like I said, I am not sure what that error means SDB FIS.

Hi All,

I've got a degraded RAID5 which I'm trying to add in the replacement
disk.  Trouble is, every time the recovery starts, it flies along at
70MB/s or so.  Then after doing about 1%, it starts dropping rapidly,
until eventually a device is marked failed.

When I look in dmesg, I get the following...

I've no idea what to make of these errors.  As far as I can work out,
the HD's themselves are fine They are all less than 2 months old.

The box is CentOS 5.1.  Linux space.homenet.com 2.6.18-53.1.13.el5 #1
SMP Tue Feb 12 13:02:30 EST 2008 x86_64 x86_64 x86_64 GNU/Linux

Any suggestions on what I can do to stop this issue?

Steve.
