My raid controller is a LSI MegaRAID SAS 8344ELP with 4x7200.11 750GB Seagate harddrives. I have the drivers installed and the storage manager software. I can see that it is Array 0 on Virtual Disk 0, all the drives are visible in the storage manager software but nothing in Windows, not even under Disk Management. Looking at the manuals too I can't find anything so far. Hopefully someone knows what's going on.

Haven't got that far yet, I would normally think to format it from Computer Management in Windows. I tried booted off a Ubuntu 8.04 CD and use gparted to create a partition, but it only let me select 44GB and left 2TB untouched. Also it didn't do anything. If there is any other way I should go about formatting it please advise, I'm probably just being dumb :p

Well, I'm running vista, and the disk management thing that comes with vista is pretty good for formatting things. what are your options at this point?

Called LSI they're no help at all tell me to call HP, called HP, they're even more useless. Please say someone knows what's going on.

Might be a stupid question, but have you installed the drivers for the RAID controller? In device manager, does it show your RAID controller or do you have a yellow items (the yellow exclamation or question mark--can't remember which)?

It's been a while, since I no longer do RAID 5 arrays. But don't you have to initialize them before you can partition/format them? My recollection is that this takes a while with RAID 5.

If the array is created and it shows up in Ubuntu then it's a Windows driver issue.

I tried booted off a Ubuntu 8.04 CD and use gparted to create a partition, but it only let me select 44GB and left 2TB untouched.

That seems backwards but if you're using a PC BIOS partition table then the largest partition you can create is 2TB.

Figured it out, XP has a 2TB limit, that's why it couldn't see my array (slightly over 2TB)
