|Good news... However... might be wise to make a backup (an image) of the drive as is to optical media.I ssggest using Acronis to this end; it's simple to use and "duz wit sez on the tin/label". Amazon often have a deal on it too...|
At the least ensure all data etc. is copied off to optical-media; and sed copies verified OK on at least one other system; and then regularly update the copies etc... That way if things do finaly go pear-shaped with the drive... data at least is secure?
Might also be wise to regularly check the HD - and if errors start a-popping up.. replace it sooner than later.
