A friend of mine just got Abit IC7 Max3 and he wanted to do SATA Raid 0+1 with (4) Maxtor 6y120 120GB SATA HDs. Last night, we installed everything correctly to each SATA port ie first HD goes to SATA1 etc. yet the BIOS only read 2 primary drives. I think lack of instructions in the book (or my knowledge thereof) confuses me when the other two becomes logical drives. What is logical drives and why the MoBo would not read them and accept them as HDs when I tried to set up RAID 0+1 (Raid10)? What in my installation procedure that was missed and/or skipped? Can somebody help me out?
