A disk-I/O error has occurred; Guild Wars 2 will now Terminate.

[Avraham.8504]

As of today (5/28/19) I'm getting this error (see Title) every time I attempt to download the new update. Thus, I cannot play.Anyone else have this issue or know of the fix? I've already tried re-starting my PC.

Update: I downloaded CrystalDiskInfo 8.1.0 and both my SSD and HDD have a rating of "Good."Thankfully, I don't think my SSD is going bad (from what I've read, that's a prime cause of a Disk-I/O Error.

2nd Update: Uninstalled GW2 and re-installed it in another location (Program Files (x86).re-installation was successful and I was able to log in and play.

Will try again tomorrow to see if I have any issues (again).

3rd (and last) update. I was able to play w/no further issues.If anyone else receives the Disk-I/O Error, I highly suggest you check your HDD or SSD first.However if you don't find a problem, try uninstalling and then reinstalling GW2. It seemed to work for me.

I suggest you create a folder specifically dedicated to Games and install all your games there, as the Program folders are also used for some of the OS related programs.

Thank you TheQuickFox & Ashantara for the suggestions!

And what do you think this would do?

They are still on the same disk and still in the same blocks, a folder or location in the UI has nothing to do with placement on the physical disk. Now, if you wanted to make a separate partition for games so in the case of corruption you can do a block by block wipe to see if it will fix the problem without having to wipe the whole drive and as such OS and have to reinstall everything else, that might help in some very limited cases. Other than that, making a folder just for games will not do anything for disk related problems.

Bring order to your system. ;)

P.S. Should have added suggestion to add a separate logical drive (partition) for your games (and perhaps non-system related programs as well).
