I recently got an XServe A1246 and am looking to install two 1TB Drives in a RAID in it. The issue that I am having is that neither of the 1TB drives are being recognized when trying to install an OS or looking for them in Disk Utility.
Before I got the two 1TB drives, I had a 500GB drive which is successfully recognized and shows up as an available drive when installing an OS.
I have included pictures which show all 3 drives and the caddies they are in. The 500GB is in the 80GB caddy and the two 1TB are in the 750GB caddies. I have tried swapping around the drives in the caddies, with the 500GB drive working in all 3 caddies and neither of the 1TB drive working in any caddy.
One thing that has worked for the 1TB drives is putting them in a hard drive dock, then plugging the dock into the server via the front USB port. I was able to see, format, and even put the drives in a RAID with Disk Utility using the dock, but even after doing that they wouldn't show up while in the caddies.
I haven't been able to find much information anywhere about what might be causing this other than maybe the caddies not being compatible with the drives, which I'm a little confused on considering the 500GB drive works with the 80GB caddy. Or possibly the speed of whatever SATA the 1TB drives use is too high for the server, or something like that. I read somewhere about using a jumper on some pins on the drive but haven't been able to figure out exactly what pins on my drives are which, or if that's even the issue.
If anyone has any ideas I'm open to trying anything at this point lol. I hope I've given enough information, but I'm happy to provide any info I might have left out. Thanks in advance to any ideas.
