I have an older My Book Essential 1TB USB 2.0 external drive (older, plug in power adapter)
Anyway the disk is empty, formatted for NTSF and no WD software on it. When I run Crystal Disk I get a Caution error:
Yet when I run a DLGDIAG quick test it passes.
I started an extended one and so far it’s been running for 7.5 hours and says time remaining is 1.21 hours.
First, how accurate is crystal disk (which gave me that report upon launching the program, didn’t seem like it “ran” anything)
Second, how long should an extended DLGDIAG test take? Is 7-9 hours normal?
