I bought a-data premier pro sp900 256GB m.2 ssd and I have problems installing win8 to it, even detecting it in existing win8 installation on hdd. SSD is detected in bios, but when I boot windows8, it disappears from device manager after cca 30 seconds and then it is missing in the bios after restart. It is only detected again after full shutdown and turn on using power button. When I tried to install windows 7 on it, I've had no problems, win7 runs fine from this m.2 ssd, so the ssd is not faulty, but I want to use windows 8. The only way that this ssd is working in win8 is when I set sata controller in bios to compatibility mode, but I don't want to run ssd in IDE emulation without ahci or trim support. What is interesting, that ssd also disappears in linux (archlinux with latest 3.16 kernel), so it must be caused by some feature that is supported on win8 and newer linux kernel, but not on windows7. I installed unlocked bios and tried to change some sata controller settings, but nothing helped.

Did someone managed to install windows 8 on this laptop on m.2 ssd?

I have 7 days to return this ssd with full refund, so it would be great if some solution could be found in this timeframe

I found these two events in event log right before disappearance of the ssd

Reset to device, \Device\RaidPort0, was issued.
Disk 0 has been surprise removed.

i have exactly the same issue, except that the ssd model is a-data premier pro sp900 128GB.

have you find a solution?

thank you!
