Raid0 4 disks

Have you gone into the RAID configuration and check it?

Hope you are backing up your files to external media often runing 2 RAID 0 setups this way.

thank you hang-the-9
raid settings in bios are ok
ubuntu recognizes both drives
installing win7 64 shows both (2 raid) drives
after install the 1.5 tb drive is gone
hardware shows 2nd drive not initialised
and yes yes yes yes thank god, i backuped 1 tb of music and movies
