It let me Open one harddisk, then just stopped after I took it out, I've tried with my laptop and it works just fine. I've tried different harddisks and cables, ports and all the other stuff. It's my computer there is a problem with. I've cleared registers and fixed issues with CCleaner, still not working. If someone could he me I would be very grateful, as it would save me at least 20 hours of finding stuff online.
