And no, I don't want to move ARMA over to a HDD because it is so freaking slow loading large mod or terrain content during gaming. I don't think my SSD is going bad but I don't have the funds to buy another SSD to test. I don't want it to kill my SSD as I know there is a life cycle to how many read and writes it can handle - Intel 960 GB SSD. I don't know what to do other than systematically go through the ARMA Launcher, manually uninstall the mods, then delete the files, then redownload it from somewhere else because it appears Steam Workshop is going into some kind of update/validation loop on my computer. Then I see 100+ GB free on the SSD, and have to re-download the 29.7 GB all over again, and validate it again. Then it stops, and indicates update needed. Then I watch my SSD free space shrink down from 100+ GB to ~ 15 GB (!!!) then Steam Client indicates it is validating the ARMA 3 Workshop Content. I subscribe to it and Steam client says there is 29.7 GB to download and update. So I tried to reinstall some of the bigger mods such as CUP. I physically goto my !workshop folder to take a peek and it shows 2500+ folders! It may be a Steam Workshop Subscription Limit?! It worked for all the mods that were listed but the launcher is still missing a bunch of mods, even though I checked and the files are physically on my SSD.Įdit - I look at ARMA 3 Launcher and it lists 300+ mods from Steam Workshop. Then Steam seems to update fix all the smaller mods, even though I had to RIGHT CLICK on the the mods in the ARMA LAUNCHER to repair it. I free up about 100+ GB off my 960 GB SSD. I kept some smaller mods as I didn't think it would be an issue or the mission files. I uninstalled the bigger collection of mods like RHS, CUP, IFA, and etc. I then attempted to fix my Steam Workshop collection by unsubscribing and deleting some mods off the SSD as I suspect it was a free space issue.

its mainly ARMA 3 and Steam Workhop, not Steam with ARMA 3. I don't have any issue with other games such as Killing Floor, any of the Valve games, BF, or etc.

I've had many Steam update issues with ARMA 3 only in the past, just check this sub forum and BIS Wizard has helped me a lot. So I had recently fixed ARMA on my computer and was able to play the basic game, no mods.
