SCSI issue on a Dell 1500SC (Solved)

Hi all, I experience a strange problem with my 1500SC. It seems as my HD is going offline after a couple of minutes and does not come back online. It all started out a couple of days ago, I installed Linux (SME Server) in a Raid1 configuration with 2 HD. After 3 days one of the HD gave me error messages. I took out the HD and re-installed the OS in a non-raid configuration but now that HD will go offline after just a couple of minutes. Also, sometimes the HD and the backplane is not found during boot. I do not have a RAID controller in this server. At this point I'm not sure if the problem is the HD or the backplane. Here are the last entrees from /var/log/messages :

Aug 5 18:01:16 office kernel: (scsi0:A:1:0): No or incomplete CDB sent to device. Aug 5 18:01:16 office kernel: scsi0: Issued Channel A Bus Reset. 1 SCBs aborted

And here is the last dmesg:
