So my late-2012 Mac mini i7 2.6ghz quad-core , 16gb RAM with 2 x 1 tb internal drives has been a rock-solid carrier for my music and plex libraries for years . I have 3 x 8tb and 1 x 4tb WD Thunderbolt Duo drives daisy-chained and again , worked perfectly for years . Cue Catalina 10.15.4 and now external drives will not mount at all although 'Recovery Mounted ' 'Recovery Unmounted' messages appear onscreen briefly . I tried the drives individually and with different cables to no avail .

I reformatted the drives to APFS and tried again but no difference so now I have 28tb of unusable space . Has something changed even more drastically than I originally expected with Catalina ?

Any other ideas or similar experiences ?

Thx
