Lately I have been noticing the NTFS partition being slower than
usual: telling me I am not allowed to open that partition and/or the
OS doing it itself but taking its time (like 5 seconds). The other
partitions mount just fine, so it doesn't seem to be a hardware issue.
Is that disk partition somehow going bad or there might be something
else going on?
Also, the disk seems to be somewhat noiser now or I am not sure if I
have started noticing it to be so because it is failing.
The best thing to do is run some tests on the disk, like the long SMART
test.
If you see lots of disk errors - there's a good chance you're having
hardware or media issues, backup as quickly as you can and replace the
drive.
Also just check the total hours-in-service against the rated life for
your drive.
The thing to watch out for (learned the hardware):
- server-grade disks fail quickly, relying on RAID to take over
- commercial-grade disks, on the other hand, will keep trying to read a
sector - trying as hard as they can to retrieve data - even if it takes
100s of attempts, and tens of seconds
It can be really confusing to find that one's machine is getting slower,
and slower, and slower, for no apparent reason.
