disk drives can still give off signs that they are about to fail. Including:
Drive LEDs that never go off. There's no relationship between overt computer activity and hard
disk drive activity, as indicated by the drive LED. But if the LED used to come
on intermittently and now glows constantly, something is very wrong and is
probably going to get worse.
Disk takes a long time to come up. A hard disk drive that takes a long time to boot up is working
hard. Maybe it's working hard because a lot of stuff needs to be initialized.
But it could also be trying to compensate for intermittent read/write failures.
Disk cannot locate file table. If the disk can't find the Windows Master File Table (MFT),
especially after an unexplained crash, the disk is almost certainly dying.
CHKDSK shows bad sectors. Bad sectors used to be a fact of life. Not any more. These days,
any bad sectors showing up with chkdsk or similar disk test utilities usually
mean the disk is going away. This is doubly true if the number of bad sectors
is increasing, even very slowly.
Running hot. All drives get warm, but
if the hard disk drive itself is running unusually hot compared to others in
the enclosure, it is probably nearly the end of its useful life.
Consider the drive's history. A hard disk drive that has been dropped onto a hard surface
(running or not) or else has overheated should be regarded with suspicion. It's
a good candidate for failure. Overheating usually occurs when an enclosure's
main fan or fans fail, allowing temperature to build up. If the system gets hot
enough that you start getting read-write errors before the problem is spotted and
fixed, there's a good chance the lifespan of the drives has been drastically
