	Some day "they'll" admit that there are "other" O/S's out
there, eh??

	One of my paranoid problems is that I can't get Win98SE to
work with any flash/jump drive, only an USB mouse, even with the
driver supplied by Lexar's site, trying on three different machines..

	Now that I have it reformatted as vfat, 'dosfsck' gives it a
clean bill of health; giving more details than badblocks of course..
I find the drive I have is USB 1.0, so it's not up to speed so to
speak, eh?

	Yes a simple desktop, a machine that can be connected to wide
band for faster downloads than our rural home machines using antique
twisted pairs, lucky to get 3.0kBps.. I admit I cried wolf before
putting my brain in motion and didn't troubleshoot properly..

	Running Unix for years now I hope I know about umount but
have to be honest that we sometimes "forget," eh?? Am, really, not
sure of the complete details.. In the heat of "battle" I flipped and
didn't do many things I should have.. At least all is well now with
the vfat format.. I hope it's not an intermittent thingy.. Oh well..

	Everything I have here is ext3 but I used ext2 on that drive
because I didn't want to rock the boat away from a device that's
marked "Windoze" only... <grin> I'll keep it vfat and be done with
it, as all suggested.. Believe it or not I've actually talked to some
hardware vendors who haven't even "heard" of Linux... Ugh..

	Lexar support has been excellent otherwise with, actually,
too many messages, but they seem to want to try as long as I don't
mention Linux (maybe.) Wonder if they'll talk to me as to why I can't
get Win98SE to work with either flash/jump drive I have?? Lexar
support answers eMails within hours instead of the normal days of
others, if at all...

	Appreciate all!!
