I currently have an Aurora R4 with two Seagate Momentus XT 500GB in Raid and just bought a Samsung 840 PRO 256GB SSD to run my OS and various programs off of. I installed the new SSD in one of my drive bays -- used an ICY Dock 2.5" to 3.5" SSD HDD Converter -- and it won't detect it in Windows 7 or BIOS. (Also tried plugging the drive via USB) I wanted to do a clean install and I've disabled Raid in BIOS and changed to ACHI, still not showing up. Wondering if I have a SSD that was DOA. Also heard a rumor that the new Samsung SSD's don't play well with Dell hardware. I'm going to return it if I can get it resolved. Any suggestions?
