I had a dead computer. I just wanted to take some important files out of its SATA hard drive. So I bought a usb to SATA cable and adapter on ebay. Getting all the connections rightly plugged, and the ext hard drive has its power on and everything working, my laptop detects the USB, when I open my computer, 4 new hard disk partitions appear as I, J, K and N, along with the partitions of my the drive in my laptop, i.e., A,C, L and M. But the new drive partitions' icons do not show up with its "storage and used space" bar and also when I try to open one of the new partitions the computer freezes for a moment and then a message pops up saying "I: refers to a location that is not available" adn that network and all crap message. Also the drive partitions' icons keep disappearing and reappearing each minute. Once I was lucky enough to quickly try to open one of the partitions, before they vanished, then for 2 seconds I could see the files that I had on that drive(Oh that feeling of seeing the dear files you saw an year ago)but the window automatically closed saying the the drive (I has been removed although the usb detector in bottom right taskbar correctly shows the usb as connected. HELP.specs- DELL 14z laptop, i5 2.5 GHz, 6GB DDR3 RAM etc.(Don't worry about the specs they are good enough). HELLLLPPPP!!!
