Good day, for the past like 4 months I have been getting this error: "error Reading/Writing: The Request could not be performed because of an I/O device error. (1117)"

I have no idea why this is happening. I had an external drive that I would move the files to upon completion and I recently changed my D drive and upgraded it with a new one, but aside from that, no hardware changes on my computer. I am using the latest version of tixati on windows 10 and I've even reinstalled tixati hoping it would fix the issue, but it persists.
Why does this keep happening and how do I fix it.

when it first started it was only a few torrents, now it does it for well over 70% of downloads

I/O device error comes from the system, not Tixati.
1) The storage medium is failing physically (your HDD is dying)
2) The connector is not properly seated
3) The USB-SATA controller is dying. It was an external HDD right?

Example of #1: Your HDD has a couple of bad sectors and when the system tries to access them, everything else from that drive freezes. Get a tool like CrystalDiskInfo to see if the SMART health values look good.
