I just got my m240 last week, and I am using Win2000, SP4. I’ve only tried MSC mode, and copying music files to and from the m240 like a flash drive. I haven’t yet any problems transferring files, having the m240 update its library, and playing music. I am still trying to figure out how to get tracks on an album to play back in order, but I don’t think that’s related to using Win2000.
A related question is if anyone has tried syncing the m240 via Windows Media Player 9 on Win2000. I know the m240 officially requires Media Player 10 and WinXP, but I’ve come across Sandisk documentation that implies that Media Player 9 is ok, which can be run on Win2000. I might fool around with it myself [if I have time!], but has if anyone else has tried it?
I have used my m240 on both operating systems. They worked great right out of the box a year ago, but not anymore. Media 9 and 11 won’t even list the songs I have on the mp3. Won’t let me delete them, especially when I have put the same song on more than once. I am not pleased with this at all. I am sorry I am no help, but I just wanted to warn you before you try.
