Installing difficult

Purchased for its attractive price despite features slightly down compared to last generation SSD. More than enough to boost a minicomputer, which was the goal! By cons, once the SSD physically set up, unable to install any operating system !!! In case a protected partition on the root disk, refusing formatting. Three days of hassle, and the use of multiple software to successfully deal with them. Good luck to new users. This bypassed the problem, the SSD gives me satisfaction in its context of use. My MiniCompaq finally launched at an acceptable rate, and almost instantly turned off.
By cons I think on a more robust configuration another choice would probably be more appropriate.
