comment Should I worry about the noise my PC makes after installing a second GPU?
It seems normal for being under some load: hardocp.com/article/2009/10/12/… I'm not a gamer though, they'd know better.

comment Should I worry about the noise my PC makes after installing a second GPU?
It sounds okay to me for speed and temperature. The engineering specs would have the details. I clean this kind of thing by shutting the machine down, unplugging it and using a small stiff paintbrush to brush the dust off each blade of the fan. It may not be possible to get under the fan. Try the top only first, plug it in and see if the sound is there. If it is... try again or try canned-air. If it's still a problem, you're looking at removing the fan/heatsink and cleaning it thoroughly or replacing it. (BTW, if you can live with the noise, the machine is probably ok.)

comment unreadable hard drive partition. is partition table corrupted?
@XXL agreed, it depends on the importance of the data though. If the C: drive has the only copy of the family photos... then take a dd. Technically, reading should be safe. Any attempts to perform recovery might trash the C: and D: partition, particularly if you're unsure of the tools.

comment unreadable hard drive partition. is partition table corrupted?
Accessing it, no. But be paranoid... I would not attempt to repair your C: partition until your D: partition is backed up. The two partitions are recorded on the same partition table. What does testdisk say? I ran a test against my own system. I added the output of a scan of my own partitions to my comment. Could you post what it says about your messed up drive?

comment Why is passwordless ssh not a terrible idea?
Depends what you mean by "passwordless". Public-private key authentication in SSH is common practice and is far superior to password-only logins. The trick is that your private key must be protected. Most people protect this with a passphrase sufficiently complex to protect against offline brute force attacks, and use strict online protections (e.g, a well patched and monitored admin machine) to keep even the encrypted private key secret. "more secure manners" depends on the security architecture. In small environments, public-private key ssh is often the best solution.

comment Is it possible to create a software RAID 1 with different sector sizes?
So your clone was successful but now when you try to mirror to your new Seagate it is telling you that your WD has 512 byte physical sectors?(!!)

comment Are USB hard drives really reliable enough to backup to?
@Paul, They're the same HDDs inside your computer. Aside from being carried around and bumped and stuff, there's no difference. The USB-SATA adapter and the external power supply are your most likely electrical problems. There are a lot of cheap manufacturers with weird names who produce bad enclosures, but in my experience, when they fail, they fail the first time you try to move a few gig back and forth or leave them on for a few hours... buy from a good computer store with a good exchange policy and test some heavy transfers before you rely on an enclosure.

comment Is it possible to create a software RAID 1 with different sector sizes?
The "allocation unit" is the cluster size for NTFS. Functionally, I think it's the same as what you mean by "virtual sector size"... it's what the filesystem is using as the minimum allocation size. You won't be able to reformat one to match the other, but cloning should work if your disks are well supported. I'm surprised at the limitation... no idea how to fix it.
