Who said anything about "indefinitely"? It's very possible for a user to pull out the drive within seconds after hitting "save" - or even at the same time.
Everybody in the thread were talking about 'indefinitely' - you are forced to hit 'eject' to safely remove USB storage. This is required even if its many seconds or minutes after use.
Hm, I thought that was just in case some other process was using the disk. I mean most of the time, you can yank a FAT32-formatted drive out without losing data.
Others on the thread report otherwise. I'm with you; I will take my drive when I'm done, and never am going to ask 'mother may I'. If it fails, I'll file a bug report. Its a minimum standard of function in my viw.
