At first I thought I had a failing external drive as it starting clicking and being all around sluggish in 9.2.8 on my Raspberry Pi 4. I took the drive and put it in my PC, using HDD Sentinel the drive is 100% with no reallocated sectors. I took the drive and fired up my old 3b and no issues. The only difference is the power brick and cable. I'm waiting on a microUSB to USB C converter but for now I have an Anker USB type C cable going into a iPad wall charger. So it appears that it's something with the 4 build or hardware related.. I also tried both USB 2.0 and 3.0 ports and getting the same issue. Has anyone seen this issue?
