You make me curious, and now I want to see what happens on my system.
On my harddrive, there are 4096 bytes per cluster. When I want to create
say 17000 small files, I need 17000*4096 bytes (about 66 MB) free disk
space. Well, I've got that free space, so it's now Euphoria's turn,
to create the files:

sequence number
atom t
integer fn

t = time()
for i = 1 to 17000 do
   number = sprintf("%05d", {i})
   fn = open(number & ".txt", "w")
   puts(fn, "This is file #" & number)
   close(fn)
end for
t = time()-t
? t/60
puts(1, " minutes")
if getc(0) then end if

It took about 18 minutes on my old PC. The last file is '17000.txt',
containing the line "This is file #17000". I looks as if everything is
correct on my system (Windows 98, FAT32).
I think you are using Windows 95, and FAT16, right? But using the FAT16
system shouldn't cause the problem, should it?
You wrote that Scabdisk didn't find an error. Maybe you should try a
tool such as Norton Utilities?

Sorry Kat, I think I can't be of much help ATM.
