That seems to be what my google searches revealed. After all, nothing is perfect. I'm sometimes surprised that drives aren't shipped with a couple of these. I'll keep my backups up to date as usual tho. ;-) >> >> Given the low number and it showing it corrected that error, and then >> passed a short and long test, is this drive "safe enough" to keep in >> service?

My understanding is that SMART detects media problems and sometimes even when a electronic component is getting out of spec. However, it is unlikely to detect that the spindle motor or the mechanism that moves the heads is about to go out. It can detect some things but not everything. From my understanding, it is mostly about monitoring the magnetic media itself. It is however, better than nothing at all. >> >> Thoughts.

It's down to 10% on long selftest and no errors reported yet. I'll keep the drive unmounted until Friday tho, just in case. Thanks for the opinions. Dale :-) :-)
