Well, the replacement for the DOA unit I got to back up the 705N with the failed drive finally arrived.

I've updated the Dell 3.4.790 software to the SNAP 3.4.805 successfully. I've also upgraded the RAM from 64MB to 256MB. I installed 4 new Seagate 160GB drives, and one of them has failed so I'll need to replace it, but I have a couple of spares so that shouldn't take long.

Can anyone tell me what's the best way to allocate the RAM? A posting on the Dell 705N forum suggested that after upgrading the RAM to 256MB, and if you're not using Java, to do a "config raid cache 160MB" to allocate the RAM to the RAID cache. Anyone know if this is a good idea? Or should I leave the raid cache at the deafult 1/4 of physical RAM?

As soon as I get the new unit up and the files from the old one backed up, I'll start playing with the old one to see if I can figure out why the raid refuses to rebuild. Some things I've read here, and the posting alluded to above, make me think that putting more memory into the unit may get the rebuild to work.
