If you are encountering a disk write error while trying to install something from Steam there are a few steps you can take to troubleshoot the problem.
One of the nice things about playing all of your PC games through a Steam account is that you can download the game files and store them on your local hard drive, as opposed to trying to play a game through a potentially unstable cloud server. In order to get this benefit, though, you need to actually be able to download the game and write it to your storage. It’s when Steam randomly decides it doesn’t want to do that that you officially have a problem.
Sometimes, for no immediately discernible reason, you may receive an error message when you try to download a game through Steam that reads something to the effect of „disk write error.“ As long as this error persists, you won’t be able to download any new games to your computer, which means you obviously can’t play them. So, what causes this mysterious hiccup, and more importantly, what can you do about it?What is a disk write error?
Broadly speaking, a disk write error means that something has gone wrong in your computer’s efforts to download data and write it to your physical storage, be it a hard disk drive or solid state drive. As far as Steam is concerned, it means the same thing — you attempted to download game files from the Steam server, but something is preventing the files from being written to the designated Steam library directory on your storage.
The cause of this error is a bit tricky to discern because it can be any number of things.
