The Crucial M4 256 GB SSD on one of my secretary's PCs locked up after a momentary power failure last night. I got the unlock procedure from a Crucial support tech, and SSD unlocked on first try using another PC with SATA drives, but boot into Ubuntu (generic 48) gave a whole bunch of gibberish ending with an initramfs prompt. Entering help gave a whole list of commands without any explanation of what to do with them. I repeated unlock procedure and moved SSD back to my secretary's PC and same initramfs error came up. The SSD also has a Win XP Pro SP3 partition and it booted normally so drive is likely OK.
What to do next? All production data are backed up on SpiderOak so worst case is to reload 12.04 64-bit. My first choice of action would appear to be YannUbuntu's disk repair CD. Is that likely a good choice or is there something better. In laymen's terms, what has really happened?
