EDITED - Updated to be more specific
I think a may have a faulty HDD, but I'm not sure - I'm getting some interesting symptoms. I need help identifying and diagnosing the source of the problems. I'll give some background information which may help.
The machine has an SSD (c) and 2 HDDs (e,f).
- C: Samsung 830 SSD 256GB (OS)
- E,F: 2 x Western Digital Caviar Black 1TB (Data & Backup)
I think F may be faulty - it often takes an hour or two to mount after Windows has started (see screenshot 1). When it mounts, it is almost as if Windows is mounting it as an external harddrive, because the "select action" dialog comes up.
However, I don't see why a faulty data HDD would cause the following symptoms:
- System boot is extremely slow (minutes when it used to be seconds)
- System tools are slow to load (e.g.: msconfig, regedit, backup)
- Windows explorer often becomes unresponsive and needs to be restarted.
May be my imagination, but the system seems to be more responsive after F has mounted.
I have antivirus software (ESET), which is fully up to date. I have also run Malwarebytes and taken the actions that it suggested.
I ran AS SSD Benchmark and the results, while unspectacular, are OK - I think. see screenshot 2.
EDIT - test results
Ran SMART tools against F as suggested. Went with HDTune. The results show that F is indeed faulty:

I shut down and disconnected F. When I booted up again the boot time returned to the 6-7 seconds that I used to get. Just to eliminate everything I shut down again and reconnected F with a new SATA cable. Boot was slow again. So I'm pretty sure that F is faulty.
I still don't understand why a fault in F would cause the OS to boot slowly. I'll try some of the suggestions in this thread on slow ssd boot times. Failing that I'll get a replacement (it's still under warranty).
