"Disk write error", at a complete loss on what to do

[Jonny]

So about 6 months ago, I got a new WD Blue 1TB SSD. I started noticing that downloading games to it would result in the download stopping multiple times due to a disk write error. Super annoying, but eventually after resuming it enough times it would finish. But the games would crash, and I'd need to verify game files, which would also give me a disk write error, but eventually would get the game to a playable state. So I went ahead and submitted an RMA on that SSD. Got the second one, brand new in the box (they actually gave me a 2TB replacement instead). Same issue. It's now to a point where basically nothing will download at all, there are 5 game updates in my queue that just break half way through the update, usually at the exact same percentage every time. I have 3 other drives, and games download perfectly to them. I also can download any game from any other launcher on this drive and it works with no issues. I've probably spent a few hours going through other posts, but every fix so far has been of no help to me. These are the things I've done:
- Reinstalled Steam (5 times now I think)
- Made an exception to Steam in firewall
- Ran as admin
- Cleared download cache
- "Repaired" Steam Library folder in the Steam settings
- Replaced the SATA cables with brand new ones
- Plugged it into every single SATA connector on my MOBO (including the ones my current, working drives are using)
- Reinstalled Steam onto the fault drive itself
- Thinking maybe it was somehow a PSU wattage problem, unplugged my other drives except for boot drive and the faulty drive
- Ran SMART diagnostics with perfect results

Does anyone have another suggestion? I've kind of just abandoned my desktop for the purposes of gaming because in the small amount of free time I've had, I just can't bring myself to look for anymore solutions.

Did you format the drive properly? (Steam works best with NTFS)
If so, disable File Indexing on the system. (right click the drive, go to properties and uncheck "the contents of this drive should be indexed" or whatever it says in your language)

You wish to make sure that the drive is always online. (not running Power Saving Mode)
I assume if you have sata connectors its a desktop, so there maybe no need for this.

Run defragmentation on the SSD. (this actually won't defrag the SSD, instead it will run TRIM once you hit Optimize.)

Try scanning the disk for errors using windows; this will fix file system issues (the journaling system maybe corrupt)

Go to services.msc and disable SysMain. (You don't need it. Less background processes, less errors.)

Once scanning the disk is done, try running sfc /scannow and make sure the core of your OS is good.

then try again, downloading I mean.

(notes: Steam shouldn't be run as admin. The Steam Client Service makes Steam bypass any permission requirements. It also helps if your drivers are up to date. Check for drivers on your MOBO website. Firewall has nothing to do with Writing Files, only with connecting to a server. You'd get different errors if that was the problem. Looking at the Logs helps (Steam/logs/content_log.txt for example. )
4KB cluster size is standard. Just use that. Also convert your drives to GPT, (not MBR, nor Dynamic) in disk management.)

have you tried repairing the steam client service? just google "steam client repair" and follow the instructions (before doing the instructions, i suggest exiting steam).

Dredging up an older post because I found a solution that worked for me which I couldn't find in here anywhere and hopefully it will help someone in a similar situation.

My situation:
Using a laptop with Windows
Steam saved in my laptop's C drive.
Running out of storage so started downloading games to an external drive but was getting "Disk write error" after downloading games and also on verifying files.
Tried a few recommendation in other posts about the issue but could not get past the error and of course could not get the games to load.

What worked for me (twice in a row so far):
Right click the game's shortcut icon on desktop
In the menu box that opens up, ignore the option to "open" the file that has a steam icon next to it.
Instead I clicked the option to "show more options", a different menu box opens up.
In this menu box I had an option to "open" the file (without any icons next to it).
Game files downloaded again but without error and than launched the game
After the first run of the game, I can now launch directly from within Steam.

Good luck.

Does anyone with issues use the C Drive for Steam Library storage and also have MS OneDrive (backup) active on said drive?
