So the first problem is the absence of instructions. I downloaded from the Internet. Then I also watched tutorials Sandisk and enthusiasts on the internet because unlike what puts Sandisk my laptop Hp has no accessible housing for the hard disk. With some trepidation, I started.
Already beforehand, you need a USB cable> Sata (not supplied) but you will find it on Amazon within 3 USB Adapter Cable 2.0 to SATA 7 + 15 Pin 22 for 2.5 "HDD Hard Drive for my laptop, it ' is what I needed. For a desktop PC, you need a slightly different cable.
So I easily cloned my hard drive with the software provided by sandisk.
Then I removed my laptop as the tutorial found on the net and have replaced the hard drive. I was lucky, the ssd drive returned easily, no need to use adapateur in the box.
I turn back the laptop and, miracle. It is lit about 40 seconds. I mean the office is displayed in 40 seconds. Well I have less storage. Hardly a 200GB against TB before but I put my old dd in a box for a memory expansion for photos and other large files.
