I had a SMART failed drive on my current machine with a RAID array. Event
appeared in windows Event log. (it was a SATA drive)
However, in fifteen years of using computers, and five running a network of
50 workstations and two servers, I have only ever seen two hard drives fail.
One of those was the SMART error noted above - which involved no data loss,
although some instability in the system before it was replaced. The other
was due to mishandling by me (moving the PC while it was running!). As I
said before, not worth losing sleep about, if your backups are reasonably
regular.
