The disk was indeed faulty !  Got my money back from Dell - reordered exact same model and it worked as it supposed to !  cheers, Kurt
I have an Dell PowerEdge R310 with a SAS 6iR Raid controller with a RAID1 volume of 2x 1TB SATA disks. The SAS Raid controller is a LSI1068E chipset. I now bought a new disk to replace a faulty one in the RAID1 volume. A bought the drive with Dell 400-18614 1TB SATA 7.2k 3.5" HD Hot Plug Fully Assembled - Kit It looks that this is a seagate ST1000NM0033. This is a 6GB SATA drive. When I replaced the faulty disk - the RAID1 set did not resync. In fact the controller didn't see the disk. When I plugged the disk into another (new) bay, then the controller did see the disk, however, it detected it as a disk with only 3950MB (4GB) ! Any idea's if this disk is : - broken ? - not backwards compatible with 3GB SATA ? - needs jumpers set to be compatible ? thanks in advance !
