I installed 7.10b3 (64 bit) on a 40 gig IDE drive on an ASUS board with an AMD Athlon FX processor and ran it as a hybrid. No problems, worked fine.
Then I installed three brand new WD 320 gig SATA drives and the machine went nuts. The admin page won't let me configure all three as a RAID 5 array (gives "damaged" error) and it doesn't give me the option of formatting the drives. LinuxMCE recognizes the drives and lets me add them as public storage, but then after rebooting the UI does not respond to commands. The cursor operates as normal, but the Flickr art loads and displays very, very slowly.
I have tried reinstalling the ISO from scratch without luck. If I leave the SATA drives (or even just one or two drives) in the machine during installation, LinuxMCE recognizes them as a damaged RAID. Deleting the RAID array from the system admin page and recreating a new array doesn't work- RAID creation fails with an error. If I try to use the SATA drives as storage (without RAID) then the UI freezes up.
Drives are good (tested them on both XP and FreeBSD systems). Any clue?
