Ca y est j'ai finalement trouvé la solution. Ce PC ne reconnait pas les ssd samsung, en lisant des forum étrangers j'ai vu que d'autres avaient le problème, tous avec samsung.
J'ai mis un disque ssd TRANSCEND et il est reconnu à chaque fois.
J'espère que çà t'aidera
Here are my observations regarding the SSD upgrade of ASUS E202SA laptop.
SSD Samsung EVO 850 250 GB turned out to be compatible with my E202SA (model FD0013T, with freshly updated BIOS version 302, 17/10/2016). In order to match the SSD size, the Windows 10 system partition on the original 500 GB Toshiba HDD was shrunk to ~200 GB and the recovery partition moved to the end of the reduced system partition - using free EaseUS disk tools. After that, the HDD was cloned to an old Samsung 850 EVO using Acronis True Image 2015. For cloning, the SSD was connected to USB 3.0 using an Icy Box IB-124CL-U3. The laptop BIOS recognized the cloned EVO 850 as a bootable drive , with all default BIOS parameters (I didn't change anything after BIOS reflashing). Win10 booted without problems and the system drive was automatically identified as SSDs. I only enabled the drive optimization and, for safety, disabled the defragmentation task in the task scheduler. The page file size was manually set to 4096-8192 MB for the original HDD and I did not change this setting on the cloned SDD.
Initially, I was going to use a new Crucial MX300 (275 GB) which was claimed to be compatible with Asus E202SA. (BTW, Acronis True Image came together with the MX300). I initialized the new MX300 using the IcyBox conected to the laptop, then mounted it on the E202SA and successfully installed a fresh Win10 on it, using the laptop installation DVD. Later, I decided to install MX300 on my Win7 desktop PC and used the old Samsung EVO 850 from that PC for the laptop upgrade.
One more observation: I switched to IcyBox after several failures to clone using a 2.5" SATA-USB3 enclosure Digitus DA-71030 (random write errors occurred in Acronis and other cloning programs).
Conclusions:
1. Crucial MX300 and Samsung 850 EVO are compatible with Asus 202SA laptop - at least, if the BIOS is updated to the latest version (available from Asus).
2, Cloning was done with Acronis True Image 2015 running on the laptop and the target SSD mounted on USB-3 Icy Box IB-124CL-U3.
3. Digitus DA-71030, very handy for archiving and small backup tasks, proved to be not good for HDD-SSD cloning.
