I was just wondering if you have actually had a problem with your Crucial mSATA drive not being recognized after a reboot.
I have both Crucial M4 and mSATA drives. I did have a problem with one of the M4 SSDs not being recognized, but was able to fix it using the power-cycle technique described by Crucial, followed by initializing the SSD by inserting it into and taking it out of a StarTech dual port docking station. I did not lose any data. However, there is no docking station I am aware of that has an interface or adapter for an mSATA drive. If the mSATA drive were to "lock up" like the M4 SSD drives, then I'd be forced to send it back to Crucial to repair or replace. I would also lose all the data on the drive. Therefore, it would be, I believe, beneficial to all users of the Crucial mSATA drives to know if there is a similar issue with their drives.
