I don't know if this is a hardware problem or what I have an older PC with 2 SATA ports, and the 2 IDE ports. IDE 1: 80 GB HDD (boot/OS) IDE 2: optical drive SATA 1: 1 TB storage SATA 2: 1 TB storage I was using this just as a "server" to access the storage drives with no monitor. I switched routers and it stopped working properly so I let it sit for a while because I was too lazy to check it out. Turned out that problem was just network settings. ANYWAY, the first time I booted it worked fine with all drives connected. I then decided to disconnect the 2 storage drives to do Windows updates and some other things so they didn't keep spinning up and down over and over. I reconnect everything and now Windows just freezes during boot. Freezes booting safe mode. I can't even re-install the operating system. (Everything shows up in BIOS) If I disconnect the 2 storage drives, everything works fine again. I dunno if this is Windows related or hardware related, but I did apply Windows Updates before this all happened. All security updates. I didn't install 3 available "recommended updates" I tested the IDE drive w/ MHDD everything was fine it's just slow (40-50MB/sec) Tested RAM with memtest it is OK. I guess I'll fresh install Windows 7 w/out the 2 drives connected and hope it boots when I plug them back in. (not hopeful) After that I guess I'll scare up another old IDE drive to put in it. Unless anyone knows what is going on? I mean I didn't do anything except Windows Updates. That's all I can think of. But why does the Windows Setup freeze on "Setup is starting..." ??? The drive just isn't working for some reason, and it did before. edit: I don't think it's a power issue, I disconnected the SATA cables and left the power connected to the 2 storage drives and everything worked fine edit: MHDD is working fine testing the IDE drive w/ all 3 drives connected edit: it booted into Win 7 desktop this time but one of the 1 TB drives had a problem. so now MHDD'ing those. this board does not support ACHI. these SATA's are showing up in MHDD and there's no BIOS options.
