comment How to delete a file that's no longer in the directory?
Of course dot is allowed; every file has one on windows. Think *.exe, *.doc, etc.

comment Anything I can do about erratic hard disk drive speeds
Seems seagate has been making some shi*t drives lately. According to their specs, this drive is only rated for 2400 power on hours ( wtf? ) and yours has 7151. Combined with all of the bad sectors, looks like the drive is shot. I guess the lesson here is don't buy seagate.

comment Anything I can do about erratic hard disk drive speeds
@BiTinerary, no, 7200 rpm is the "standard" speed these days ( well, for the last 10 years nearly now ) for desktop marketed hard drives, regardless of capacity. Drives marketed for backup, near line, nas, or low power ( like WD green/red/purple ) operate slower ( 5400-5900 rpm ). You can tell these drives because the manufacturers avoid specifying the rpm. Also drives use less than 10 watts, so even with 3 of them, that is still far less heat than you are going to get out of a busy cpu or gpu -- quite easily cooled unless they are all crammed tight with lots of cables blocking airflow.

comment Raw reading USB mass storage or SCSI
@Otheus, nope.. ECC is performed on blocks as well ( at least the reed-solomon type used in hard disks ). They are designed to correct longer bursts of errors rather than the single odd error scattered here and there ( like a hamming code ). The only way hard disk capacities have been able to scale the way they have in the last 15-20 years is by being able to correct numerous errors inherent in packing bits ever closer together, not just one bad bit in 512 bytes.

comment Raw reading USB mass storage or SCSI
@Otheus, I pointed you there to show just how common knowledge this is and how easily you could have found it had you bothered. It is clear now that you would prefer to engage in ad hominum attacks rather than actually learn something.

@Otheus, do you really need that much handholding? You couldn't be bothered to search the page for CRC?

comment Raw reading USB mass storage or SCSI
@Otheus, nope, doesn't work that way. Before the CRC there is an ECC. Up to a certain number of bad bits, it corrects, but as soon as you go over that, it starts spitting out garbage.

comment When do I need a pure sine wave UPS?
That bottom waveform is what the output from my 15 year old cyberpower 1000 avr looks like. It's ugly, but it's never caused me any problems. The dual 8ah batteries ( in series for 24v ) cost me only $20 each to replace every 3-4 years and I think I paid $100 or $150 for it new.

comment When do I need a pure sine wave UPS?
@PlasmaHH, really? I can see a square wave overloading and/or damaging cheap wallwarts, but modofied sine wave is usually "close enough". Come to think of it, I've never had anything damaged on a crappy square wave inverter; they just put out a bit more heat, which they can tolerate just fine for a few minutes when mains fails.

comment Restore HDD state after making it all one partition
If you chose the third partition, then you blew away the data on that partition. The other partitions should have been unaffected.

comment Stabilize massive heat sink before shipping PC
@Tetsujin, you're supposed to pad it enough so that if the box takes a reasonable knock, it won't shock the computer that much. Enough force to dislodge a properly fastened heatsink is enough to damage the hard disk.

comment Stabilize massive heat sink before shipping PC
If the heatsink is properly fastened on, and the whole case is boxed properly with padding, then it won't come off.

I assume you were using the SSD to cache the HDD. It sounds like the HDD simply died.

comment WD Blue Hard Drive - BIOS Shows 0
Sounds like a bad drive. Test it in another computer and/or RMA it ( they will probably ask you to run their diagnostic software first ).
