Personally, I never had trouble with bad disks, but with defective file systems (origin unknown), and follow-up trouble caused by background fsck that prevented me many years from accessing my data. Going the "old fashioned" way brought everything back. Long story short: A present .snapshot from the 1st background fsck (which was introduced as default in 5.0, as far as I remember) caused fsck from working as expected; after removing this file, I got all the missing data back. Luckily, the problem didn't seem to be related to actual disk failure, as SMART data didn't give a hint about that. I did work with a 1:1 dd copy anyway. > Modern disks die silently which I think is too bad. You usally see messages in dmesg / console that indicate disk trouble. In mos cases, those messages say that the disk is already dying - it's too late for "repair". So time for backup and replacement. Seems that this is the result of continuing bigger and cheaper disks... > If this is > happening and you have data you want to recover you > might try booting in single user move and using fsck > manually on each slice. The fsck program operates on partitions, not on slices. Terminology, dear Watson. :-) -- Polytropon Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ...
