I am having the same issue many people have posted on here about before, my BIOS will not see my mSATA SSD. I have tried power cycles of 20-30 minutes on, 2 minutes off. I have also tried a power cycle with my laptop switched on for 12 hours, and off for 5 minutes.
As this is a mSATA drive, I cannot hook it up with only power and leave the data cable unpluged.
I have tried power cycles with the SATA controller switched off.
I have tried booting from a Partied Magic LiveCD.
Can anyone please help me sort this? is there anymore tips? other advice?
I don't recommend doing this, but I had a backup and I'm just fed up with the M4. I booted into Parted Magic, which usually makes the SSD visible again, but this time it didn't. While booted in Parted Magic, I removed and plugged back in the M4 in my laptop and suddenly a few programs in Parted Magic were able to "see" my M4 again. I was then able to start Win8 again and run chkdsk which again found more Bad Sectors.
