I've acquired a second hand Thinkpad T14 recently (gen 1, Intel version). Running Fedora Gnome.

The SSD seems fine.
I tested it with Gnome Disks; I filled the drive with files and checked their integrity; also copied files around, on drive and from USB. No issues.

But many downloaded files become corrupted. The download finishes normally, but if If I try to open said files they fail (in the middle of a video for example) and if I copy them I get an "input/output" error.
LAN or WAN, over ethernet or Wifi, it doesn't matter.

Could it still be the SSD? Or maybe a driver issue?

Thank you for reading!

Is there any chance this could be caused by malware on their router? I'm puking this right outta, well, you know where; just curious if the evidence would even fit my theory...

this can be tested by using some other machine, it is unlikely a malware infected router would serve differently for different client devices.

I mean, anything is possible, but that seems farfetched to me. The router is typically a hard target for malware unless you have physical or at least LAN access. They are generally pretty locked down and don't execute anything from remote access, they examine packet headers and send them on their way. If it was compromised I'd expect something more nefarious than ruining file transfers too.

The biggest strike against this being a network hardware/driver issue is that normal browsing works. If packets were being screwed up in transit, connections would drop, text and images would be corrupt as well (which the browser would probably choke on). It seems to have an issue only when the disk is involved, when data is being saved.
