The rest of the disc is very small, it is recognized without problems under Windows 7, not super fast but the backup is enough. The cable is a bit short but it is a problem encountered on all brands of this type of product. The finish is not bad for the price, but I find the cable connection on the drive a bit light though.
Finally, for the price it seems to do the job, but it takes a while to see if it will fail like the others, mysteriously, at the end of the warranty or not. I do not know if it's possible, but if it is, demand a package worthy of the name to not find yourself with a failed drive to delivery.
