|If everything is working fine it would ignore I for the time being. SMART does tend to be a little over enthusiastic at times. A lot depends on exactly which criteria SMART is complaining about and the are around 20 of them. I have run a hard drive for over twelve months with an imminent failure warning.|
First thing to do is go to the drive manufactures web site and download their diagnostic tools. That will give your hard disk a more thorough check out and give you a more comprehensive idea of exactly what the problem is.
Or you can download a SMART monitor which will keep an eye on things. If it is something like bad sectors than that is something to be concerned about. If it is just something the the drive spin-up rate being a bit long then that's no so much of a problem
Just to be safe make sure you keep backups of any irreplaceable data.
