Hi,
I've had a Crucial M4 64GB as my Windows boot drive since 2012.
The other day I got a warning in the BIOS to 'backup and replace' as the SMART data indicated something bad.
Crystaldisk shows 93% 'percent lifetime used' and a red dot by 'raw read error rate'.
It's the 93% used which concerns me! Is that to be expected?
Here's the start of the report from Crystaldisk:
