Hello, and I apologise if this question has been asked a billion times already. I just remembered I used to code for a living, and was idly wondering if that huge ...um... "mistake" has been fixed yet.
You know the one, where everyone has now moved on to fast but small SSD's and MS wants to dump about 50Gb of stuff on your C: drive, no options, so suck it up.
I actually quit programming because of that and now wear steel-cap boots and a hi-viz vest to make ends meet.
But I want to return to the stuff I love the most - coding.
Yup, I could choose another platform and IDE, but I don't want to.
Is there any hope?

Well, SSDs have grown in size and a 500 GB is within reach for most folks. The drive space that VS 2017 requires varies, depending on which features you install. I installed it for C# + WPF as well as UWP apps. It took about 8GB of my 500 GB Samsung SSD - virtually negligible.
I can highly recommend going for an SSD, as it just runs so much faster. I would not bother with any IDE other than Visual Studio 2017. And keep in mind the fully functional Community Edition is completely free.

You beat me to it! (I had to lookup vs 2017 typical footprint)
I really need to get with the times and move on from VS 2010. I use 2015 for a few projects, but dislike it due to load times/resource consumption. One of my new year resolutions is to install and start using 2017 instead of 2010/2015...figured the kinks should be worked out by now. 
Enjoy your weekend!

I have used VS 2010, 2012 and now 2017. The latter is by far my favorite. I did try 2013 for a short while, but did not like it. 2017 rocks!
Oh: Have a great weekend yourself!

Plus VS2017 2nd latest update has project load on demand, so it doesn't take all week and load each project in the solution on startup, but it only loads a project when you want to debug or work on it.

I disabled this. Found that when performing a search across the solution, it had to wait for everything to load. I'll take the hit from my SSD and have the whole solution ready to work.

Aaah, yes, I suppose I never noticed that because my solutions are normally very small, and it doesn't unload projects, so I probably only ever do a solution wide search once all projects are loaded.
I don't have the luxury of an SSD so I wait ages even for small solutions to load all projects.

Mostly, everyone has moved on to SSD's due to increased capacity at a lower cost. Currently, you can get a 480GB SSD for < $150 USD. You don't have to worry about a license for VS anymore, so get VS 2017 CE and forget about the 20-50GB it's going to occupy. btw, welcome back to coding!

I've had a 1TB (well, 960GB but close enough) for 2 years, and it cost £160 then - about twice the price of an equivelant HDD.
It's nowhere near full, and I have Vs 2010, 2013, 2015, and 2017 installed...
They are so worth it - the speed at which apps load is phenomenal - it can change the way you work because you don't need to keep apps open, so you get more ram to play with.

Just a few more thoughts:
If you are starting afresh, consider installing two drives in your machine: A SSD drive for the operating system and apps, and the second drive for data, including your Visual Studio projects. The second drive can be either a SSD, or a less expensive traditional HDD.
This will make it easy for you to back up your systems drive with an imaging utility, like Macrium's Reflect or AOEMI Backupper. Both of these have free versions.
Your data can be backed up by simple copying to an external drive. Your images should also be backed up to the external drive.
Leave the external drive(s) normally disconnected, in case you become the victim of malware that corrupts your internal drives.

For VS2017 I have pretty much everything installed except Android/iOS utilities and UWP. I don't remember exactly the size but it wasn't that bad (definitely wasn't over 40GB). Plus as others have mentioned you can dynamically add and remove components from your install which is extremely convenient.

While others have pointed out the benefits of using Visual Studio with one or more SSDs, my opinion is that VS and SSD should play little to no factor in your decision to return to software development. Depending on how long you have been away from software development, you may find the languages, development frameworks/libraries and architecture have undergone considerable changes. This may present a large and formidable learning curve for you, especially if you must continue working full time at construction while studying on the side. I do not know what your circumstances are but my two cents worth of advice is that a return to software development will necessarily entail consideration of more important issues than VS and SSD.
History is the joke the living play on the dead.

I sure hope that's a joke.
I don't have SSDs and do just fine at work. None of our developers have SSDs.

I've too gone all SSD, my initial worries were more about the lifetime of SSD's under heavy use, well basically even for heavy home users that was just fake news. The consumer grade samsung evo's will handle years of work.
But something else I can report regarding SSD's: a client had some software running on XP they wanted moved to somebody else's machine - 2 years back they moved to new win 7 boxes. So it was off to their hardware graveyard to find a working XP machine, every single HDD failed, every single one, just because they had sat idle for 2 years. Found 1 machine with an old Intel 60GB SSD, (had vista on it). Moved that SSD to a smaller machine, installed xp (luckily it was a dell, say what you like about dell but they still have all of their old drivers on-line, and that handy sticker with the windows licence number on every machine.) I tried VM's but something in this app didn't like VM's - xp mode, virtualbox and wmware - all problematic, running direct on win 7 also rain weirdly.
Summary: Out of a stack of 11 used HDD's and 3 used SSD that had sat idle for 2 years: only SSD's still worked - all of them! Not one spinner worked - not a single one! (The smaller cap HDD's sort-of worked for a bit but would soon fail with bad blocks, the 250G and up spinners were all 100% lifeless and wouldn't even report presense to the bios.
Seems to me SSD's are in fact more durable than spinners, and for that little bit more a way smarter investment for your next upgrade. (Yes the speed diff is hugely noticable.)
On that even my earlier idea of using spinners as a backup is out the window, (and new external SSD's are all USB 3.1 ready which given their speed makes proper sense.) Not only are they smaller but I feel way more confident both chucking them into a backpack for commuting as well as putting them on a shelf for 6 months as long generation backups.
Signature ready for installation. Please Reboot now.

To my dismay when I installed VS2017 Community Edition some weeks ago, the bulk was installed on the C: drive, despite telling the installer to install on D:.
I have a notebook with a 128 Gb SSD and a 1 Tb hard drive, the SSD is now half full already !

I kind of doubt that was the only reason. Nothing really in modern hard drives that would cause them to fail after a couple of years.
It isn't like letting a car sit in the garage for two years. Unless of course it is exactly like that. For instance the computers were left sitting in a garage-like room (little or no environmental controls and piled up on shelves.) That would probably have some impact. Or if they have been bounced around, physically, over time.
Or perhaps the computers were not all that great to begin with. And the hard drives were not good either.
For that matter were the connections resitted? Maybe constant haphazard moving around just jiggled. So fairly decent computers but the connectors were not great and they jiggled loose.

6 months isn't that long. Keep in mind if you go longer that technology does change. So even if the hardware works in 20 years (if you want longer) you might not be able to spin up a system to read it.

Yeah, the graveyard was in a warehouse, but the equipment had not been abused, just stuck on a high rack 2 years back and not touched since. No air-con, I'm told it's 25 - 30 degrees year round.
I've experienced similar before, brand new equipment can handle being stored for quite long, whereas used equipment (used daily) that is a few years old doesn't store very well.
And it still makes my point, used SSDs seems to outlast used HDDs.

As mentioned the new portable SSD's are USB 3.1 (Type-C) connector - I can't imagine these being unusable that soon. You do know motherboards still have serial and parallel ports and many even floppy drive connections, even though they don't expose them in today's cases the header cables and mounts are still available. (not to mention USB to serial/parallel/floppy/banana dongles are out there.) They still sell ps2 keyboards/mice. Many companies use dot matrix/thermal printers daily (and supplies available), I've seen dumb terminals for sale and still in use. There's companies that will help you recover magnetic tapes, heck I've seen farmers in Holland that still wear wooden clogs for certain tasks.
Technology will always be superseded/improved, yes my 500G portable SSD's will probably look small and probably be considered slow in a few of years, but will still be usable.

All true, but that is stretching "usable" a bit.
I have some games that have 5.25" floppies but that doesn't mean that they are going to work if I just dig out a 5.25" drive. Both due to the material and to the way I am accessing them.
And consider what happens in a office, where one must find the 2002 (16 years later) accounting records. Presumably one is doing that because there is a certain amount of urgency in finding them, so rooting around to find the hardware and software needed to actually get to those can be problematic due to the time needed. That doesn't mean it can't be done but rather that one should take care in assuming how suitable it is.

I've had the same experience though. I have a ton of used hard drives from various machines that we scrapped and while they hard drives were working when they were taken out, about 1 out of 10 were still working when I tried to re-image them for reuse. Most of them were Seagates. Some of them were remanufactured. At the time I chalked it up to old harddrive firmware not being compatible with new systems.
