The only enclosure I have that works out of the box is one of those “SATA to USB adaptors” rather than a bona fide “3.5 inch drive enclosure”. It’s not ideal for long-term use.
I wonder if there’s a place to find out if any given make/model of enclosure will report the sector size as 512 bytes. Then, presumably, one could purchase an enclosure off that list and be confident the disk will be readable.
