HI to all. I am gonna crazy with this problem! its like this: A few days i got an error message "a system disk error occurred, press Ctrl ALt Del". After maaany tries to recover, i decided to setup again with WInXP..so far ok. So everything went ok with XP setup but when i go to my computer now i cant see my two drives (BTC DVD-R and BTC DVD-ROM).I went to BIOS and i can see the two drives fine!!! I thought that maybe it was something wrong with the IDE cable..i changed it but nothing happend, i even plug another DVD-ROM to see what would happend but i cant see this too! I have downloaded firmware updates for both drives but nothing. some info:I have ASUS board.my HDD is SATA, and the two drives are connected to Primary IDE1.So there is no RAID problem i think since there is nothing connected there. Can anyone whats all about ? Please help.
