    Just for your Info, if SMART has been tripped, it has been tripped, that's it. You can't repair any SMART errors or messages. It's time to have the disk replaced as soon as possible, even if it is still working for the moment. SMART is there for you to get alerted and have some time to make your backups before the disk actually fails. So generally it doesn't really help to know which parameters actually tripped SMART. It's purely informative and might be of use to the HD manufacturer for statistics and for info on how to make better disks in the future...

    CRC errors are normally read/write errors, which mean disk surface errors, and the other errors you have (reallocation errors, pending errors) are a follow-up of those CRC errors because the disk is trying to mark those sectors as bad, and can't...

    So your main worries should be to get the disk replaced as soon as possible, and have your data backed up!...

    SMART errors in themselves are not as critical as the frequency in which they are occuring.  A few now and then is not bad, but an increasing number in a short time (a few days) is cause for concern.

    >>  Just for your Info, if SMART has been tripped, it has been tripped, that's it  <<   Rindi, i also thought so; but i have found out it can be reset; but i'm not sure yet how, since i tried a lot of things on an older 200 GB sata drive that stopped at post time with a smart error (the platters were ok, tested)

    it looks like writing an image changed the smart to ok - but as said, i'm not sure yet

    stkadmin, what i do is run HDDRegenerator (not free) on the drive, and check that ALL errors are repaired, to be sure about the platter reading and writing

    of course - if some other hardware is bad - that no software can repair, and you need to replace the drive, as said

    Have you done your backups and ordered the replacement HD (or gone to the shop to buy one)? As I pointed out earlier, the disk will die, probably soon, and you need to replace it asap. There's no point in getting further analysis of it's current state and waiting. Once it has been replaced you may be able to keep on using it for some time for testing purposes and non critical data. But the CRC errors and the fact that SMART has been tripped means you have to take action. Also, if you wait and don't take action, any further use and exercising of the disk will make things worse.
