One of my 2 pc is composed by an Abit Kr7a 133 raid 133. I installed 2 Maxtor 60 gb on HPT 372 raid ide controller. I created a raid 0 system. I tried to install Win XP and everything works. When instead I try to format ext2 partition it fails! It does not metter if the hd's are in raid or not. It depends only on the fact they are plugged to raid controller. when i plug them on the normal ide controller the operation succeeds. I try to format both using Suse installation dvd and by Partition Magic 6 from inside Win XP. In both cases it can only format swap partition. Mobo Bios is a modded one with a version of HPT controller bios supporting linux. Now I'm trying to flash it again with the last abit version that comprehends it too. Can anyone help me to use raid 0 with linux? THNX Blackimp
