This is a report from S.M.A.R.T. which is built into the drive electronics. Usuallly you don't get a warning until the disk is already dead, so you're lucky. :)

By all means do a complete backup immediately. The warning might be premature but I wouldn't take a chance. After you have your backup then you can hope the HD lasts a while longer while you decide on a replacement.

As I remember from my BIOS days, the S.M.A.R.T. is supposed to send a warning when the HD's store of spare sectors is almost used up. Don't remember if it monitors anything else.

Way a modern HD works, when a data error occurs, that sector is mapped out and one of the spares is mapped in. The drive keeps track of how many spares have already been used.

A suitable program can query S.M.A.R.T. but I don't know any details - as indicated above, the 2 disks I ever saw give a warning were already unusable.

Maybe others can tell you more.

Go to ADIA32 and download this free tool. It has a SMART interrogation section that will list your drives and the status. Here's one of my disks from the program display, it is formatted much better when the tabs are correctly spaced locally:
