Unrecognized SSD

The material is definitely good and I have always been satisfied with the brand but to transcend this SSD there are problems I will wish to point out to prospective buyers.
I got 1 256 GB SSD that was not recognized by computers running win8.1 2: 1 lenovo yoga pro 2, 1 and 2 yoga samsung lap. I tried on Windows 7 computers with 2: 1 toshiba satellite where it was reconu and HP touchsmart which has not recognized. I returned to the Amazon ssd for an exchange.
For the second ssd received, always the same problem under win 8.1. I looked in device manager and found that the driver was not installed for this drive while the driver is up to date (microsoft disk.sys). I have not found a solution. Win 7 on the Toshiba SSD is recognized and paradoxically it is recognized on a Windows 8.1 tablet Acer W4 but not on an android tablet. On the Acer W4 I found that it was the same driver, but there he was recognized. As I wanted to use this ssd on many of these computers, I therefore refers to reimbursement.
I should mention that for that Amazon is top. Indeed delivery (next day with premium), the second reference ssd immediately after I posted the pbs (therefore received the next day). Unfortunately I will send the 2nd ssd because ultimately this material can not satisfy my needs. Fortunately I had ordered on Amazon otherwise it would have been otherwise a hassle.

PS I forgot to point out that when the SSD is not recognized it blocks the computer to reboot (you must press and hold the off key for the reboot) and it also has it problems with USB ports which the SSD has been connected (ask the same maneuver as above for remttre things running).
