possibly need scope too

this is computer system after all

because what about noise or fast dips


i'm not surprised of hw, that is, sbc, usb-sata adapter, hdd going shit

is there s.m.a.r.t. passthrough in usb bridge? but it might not help either. i now put my old/new disks through my custom test procedure. maybe this is due

sadly can't run memtest86+ on that platform

the hell, it could be everywhere


i've noticed you run on some tight owner/power budget hw there for long time for some reason. now it "pays" back
