My problem is that since upgrading to a B2000 (4.2 rev) the drive no longer wants to work as a 'PC' drive, though its's fine as a 40-track Amiga device. The symptoms are 'root directory full' from PCcopy and 'error -4' from PCformat. Oddly enough the drive still works fine in both modes on the old 1000. Can anyone shed any light on what 'error -4' might mean, what differences might exist between the 1000 and 2000 implementations of the external disk interface, and whether or not such a latch circuit needs any additonal 'tweeks' to operate on the 2000 ??
