I ask this because I have a few BASIC/FOCAL programs that do this and I recently got some strange results from a program that was very reliable on physical hardware. The program read all nulls when reading the directory, but got mostly valid info from the header record.

The mass storage emulation is using the same protocol (the so-called "Filbert" protocol) than the HP82161/HP9114 and is compatible with mass storage operations of known controllers (HP41/71/75, HP Portable). However, the implementation may be slightly different, so if you found some deviations vs the real hardware, it's interesting to know.
Please describe your BASIC/FOCAL programs and results, preferably in a separate thread.
