To me, all the hassle a failed disk (or other hardware) will give me isn't worth saving a bit of money on it. Since you got it cheap, why not buy another one and use RAID-1 (and/or zfs)? When one fails, shutdown, replace the failed disk, restart --- no hassle involved. > That aside, the drive that failed is a Crucial m4.

When you get sector errors reported in the log file when accessing the disk, the disk has failed (provided that the cabling and power supply are ok). This goes for hard disks --- are SSDs any different in that? Other than that, I don't need any more diagnostics. It would only tell me what I already know. > I usually send them back for warranty, but this time I'm curious. Without physically destroying it, I won't give any disk out of hand which has had my data on it. Unfortunately, that probably means that there is no warranty on disks. I only take the duration of the warranty as some indicator of what the manufacturer entrusts the disk with, as in "5 years may be better than 3". In practice, hard disks either fail not long after new, or after about 3 years, or virtually never because they are replaced for other reasons before they fail. SSDs might be different; I don't have much experience with them yet. -- Again we must be afraid of speaking of daemons for fear that daemons might swallow us. Finally, this fear has become reasonable.
