The name of windows-partition changed without any reason!

[Petar Milin]

Sorry for posting this question again, but I am getting nervous and
afraid of some serious further problems and/or crashes.
The day before yesterday, strange thing happened in mu Ubuntu 6.06: I
lost the name of my win-partition, under the icon on my Desktop.
Previously, and from the beginning of the Dapper-instalation, the name
of win-partition was '/media/hda1', and now, strange character appeared:
''. The only thing I have done is defragmentation of
win-fat32-partition (from windows, of course), but nothing within Linux.
I haven't touched fstab or something of that kind.
How is that possible? Can I have the proper name back?

Sincerely,
Petar Milin
