I am in need of a SATA cable to connect my PC to another SATA drive. My problem is that i dont know if my computer has another SATA controller built in for it as the primary hdd needs to be running as well so i cant unplug it. My system specs are located on this site and more here: http://reviews.cnet.com/desktops/dell-inspiron-530-desktop/4507-3118_7-32486100.html?tag=mncol;psum On the link i posted, it says: Storage Controller Type 1 x Serial ATA - Integrated Controller interface type Serial ATA-300 Storage controller interface channel qty 4 RAID level RAID 1 I dont know if this means that i have 4 SATA Controllers or i need to go and buy one. Can someone point me in the right direction here? I will provide more information if needed. (also i am running vista home premium so if i need to buy a sata controller it needs to be compatible..) Thanks in advance for any help.
