Help needed with the Arduino HP-IL mass storage and 41c

[Klaus Overhage]

Congratulations for the successful build of an Arduino HP-IL Drive. If you ever store more than two LIF files with the extension *.dat on an SD card, there is a surprising behavior: The order in which the files are selected is not alphabetical but depends only on the order in which they were copied to the SD card. The one copied first is assigned to hdrive1 after power on and the one copied after that to hdrive2. The next LIF file selected with DDL16 is the *.dat file copied to the SD card third. The file name of the LIF files has no influence on this order.
