I do however, with this particular device remember that I at one time had this device working with my Linux desktop, and I believe it was early to middle 2.4'ish, but even then I remember that it was very fickle. I could only mount it as 'msdos' (not vfat) and I could only do one thing at a time (eg. removing old files or copying new files over) before rebooting it, otherwise it would freeze. On my PC at work with WinXP I can with no specific software remove and copy files over without any problem, and I can see that it mounts is as vfat because I can for example create files with upper/lower case. Should I investigate which 2.4 kernel it was that I could use it with? I am not sure about what the binutils and other supporting software was, but if you think it would be useful I'll see if I can find the right combination again. I have had enough bad experiences reg. contacting HW manufacturers about Linux support of their devices, so I stopped doing that some time ago (I started using Linux in 1993, and funny enough, it has never really become easier to change their minds about starting to provide info or support for something they didn't already, and they couldn't care less about a potential consumer threating *not* to buy their product, sigh!).
