This problem started to happen a while ago, its random so I tried to ignore it at the first. But I can't anymore, its extremely annoying. As you can see from the image below, that specific drive has a extremely low read speed - 4MB/s. The other drives on this PC are completely fine, no issues at all.
I've already tried a OS reload, changing SATA cables, connecting to other SATA ports on the MB, but none of those helped. A hard drive diagnostic has also been performed, but it showed there's nothing wrong.
Does anyone know what could I do?
