Reddit mentions of WAVLINK USB 3.0 to SATA I/II/III Dual-Bay External Hard Drive Docking Station for 2.5/3.5 Inch HDD/SSD with UASP (6Gbps), Support Offline Clone Duplicator and Auto Sleep Function [12TB X2 ]-Black

Prevention is the best medicine, but for now, immediately disconnect the power, and look up a tutorial on how to remove the hard drive, as long as it's not encrypted, you should be able to just put the hard drive in an external enclosure like this: https://www.amazon.com/dp/B018FTE87S/ref=cm_sw_r_cp_apa_ucIQBb0FFQWEB

And just plug it into another computer, assuming the drive wasn't fried, it should work.

The first project I wanted to cover was NAS. I currently have two 3TB HDDs and wanted a concise way of linking them to the Pi. I've been looking into the cheap drive docks on amazon, but was unsure whether those would have software hangups when trying to connect those to a Pi. Anybody have experience with using these?

If you're just protecting against hardware failure (i.e. not something catastrophic like a fire) then an external drive enclosure is the cheap and cheerful solution. Something like this

Yep, this is what I do. I build 5-10 systems a week with a consistent, highly-specialized, time-consuming install. So I use this guy:

It works for me and we have the licensing for it to be legal. I can pop out a computer every 2 hours!

If its ok to spend 28$ you have this hardware ( https://www.amazon.com/gp/aw/d/B018FTE87S/ref=mp_s_a_1_11?ie=UTF8&qid=1518249157&sr=8-11&pi=AC_SX236_SY340_FMwebp_QL65 ) wich clones hard disks on standalone mode and also you can connect It to an USB port like an external hard Drive.
This is how It works: https://youtu.be/xcDEw05_XPA

I have one and, as the IT guy, this little thing has saved me a lot of work

Edit: not sure why the downvotes. OP said spending some money would be ok and this solution seems to fit better than having to purchase multiple software for each operating system and also serves as an external hard drive. On the other hand, I gave a solution that I've tried for a long time and I now it works. I'm not tiered in anyway with this brand/product and of course OP is free to purchase whatever solution he/she wants.

External monitor would be the way to go. Beyond that, you could pull the HD and plug it into another computer. They make adapters which are cheap on amazon that allow you to plug drives into other computers via USB.

Things like this: https://www.amazon.com/WAVLINK-Dual-Bay-Docking-Station-Functions/dp/B018FTE87S

Or this: https://www.amazon.com/Adapter-UNITEK-universal-Optical-Include/dp/B06WWLCYC3

But make sure it is compatible with your drive before buying.

If it's raw drives, one of these will work

I have a good system but I am guessing my issue with the drives (which happened before) is the wavlink i'm using to connect them to my pc.
