I want to resurrect an old amiga 600 hard drive

[Thomas]

USB adapters don't work with these really old drives. You'll need to connect it to an IDE port.

It should work in an A1200 or A4000. For the A4000 you need an adapter from 2.5" to 3.5".

Thomas: Many USB enclosures use IDE - why would they not work?   New enclosures are probably almost exclusively SATA but it shouldn't be too hard to find an IDE version...

Believe me, it does not work if the drive is too old. ATA standards have changed and USB adapters don't support the very old standards.

An enclosure will not work, either, because the drive does not fit into it. Original Amiga drives (40 MB or less) are full-height drives (twice as high as modern 2.5" drives).

I have such, too. I works with every drive I own except the really old one from the A600.

And there are many other people on other forums which have the same experience.

I must admit that I never saw such a double-height 2.5" drive before I opened the A600.

Yes, it did work in the Amiga. I finally used Amiga Explorer to make a backup. Now I am no longer interested in it.

I just wanted to warn that it does not work with just any USB adapter because I am not the only one who experienced this. You seem to own the only USB adapter which works with these drives.
