#4937: USB stick not recognized when plugged before boot

Comment(by mmlr):
Replying to [ticket:4937 skfir]:
> If I insert a thumb drive before the systems is loaded, the drive is not
recognized, I have to take it off and insert again.
And by "not recognized" you mean not auto-mounted or not available to
mount from the mount menu? From the syslog, the drive and the FAT
filesystem on it are detected just fine.
> If I don't remove it and reboot the machine, drive is not recognized
after rebooting as well.
Again, what exactly do you mean by "not recognized"? Does it not show up
in the mount menu?
> And after reading from the drive, when I unpluged it, the system fell
into debug mode.
If you unplug it without unmounting this is perfectly expected and
indicates that you just lost and/or corrupted some data. From the
screenshot it looks like a read-write mounted filesystem wasn't able to
write back changes when it was unmounted because of the unplug provoked
media change event.
The second screenshot is very hard to read, but doesn't look related. It
indeed looks like a FAT problem where a block was modified where no
modification was expected. Might be a race condition and might be related
to the cluster != 0 assert.
