Yesterday my secondary conventional HDD started acting weird. No throughput or even just a few KB and it'll lock at max disk activity.
Sometimes though I can transfer large files instantly but as of a couple days it's switching between 100% activity at idle and then allowing me to use the disk "normally" briefly before switching back to this odd behavior.
Given that the disk is a few years old, is the disk faulty? Or is this a software issue in Windows 10?
