I got this failure when inserting a card with files with too long filenames. Despite that I cannot believe that there are limitations in filename length, even if the fat32- or exfat-filesystem support long filenames, I would like to know, what the maximum filelength support of the ND 2901 is. This limitation is quite annoying, cuz I want to store files not only from my camera... I hope you fix this in a soon updated firmware.

Sincerely,
Pequi
