USB thumb drive shows up twice

Dear all,
I have a 1GB USB thumb drive which always mounts in the finder twice:
i.e.
I am talking about the finder window and the desktop: once I have plugged in the usb stick it then shows two connections to the stick:
one is called:
USBDISKPRO
the other is called:
NO NAME

I just got my G5 and I have partitioned my disk, though I dont think this has any influence on my problem...

the problem is exactly the same as the one mentioned last october (please see here below) in this forum but has not been aswered.
I hope I have more luck.

thank you!

USB Thumb Drive shows up twice
Posted: Oct 11, 2005 10:07 AM

I have a 64MB USB thumb drive (the only name on it I can see is VeriTest, which might be the name of some company that was giving them away) which always mounts on the desktop twice. I have used drive utility to re-format it (but even in drive utility it shows up twice).

On a 10.3 machine yesterday I reformatted it while zeroing out all the data and it only showed up once. But today when plugged back into my 10.4 machine, it shows up twice again.

It also gets weirder... I can look at either "drive" and delete the file that is on there, but it does not get deleted on the second drive - so the two of them seem to get out of sync. I cannot, however, empty the trash because it says the item in the trash is in use.

I know it's just a 64MB little thingy, but I find it quite useful (but this is annoying when I have to reformat to erase a file)... Any ideas?

My guess is that the PC isn't showing you the second partition at all. If a drive is partitioned, the correct behavior is to show it as two separate volumes. If your PC is not showing the second volume, so showing them both as one volume, either way your PC is behaving incorrectly.

Did you install some software on your PC to use your thumb drive? When mine is inserted into a PC, it automatically installs software to manage the secure partition. Maybe yours has some kind of similar software that makes it appear as a single volume.

thanks a lot.
It really is the case, my USB stick is partitioned. Though it is partitioned strangely! I mean there are not two partitions under one heading, but two headings (each with its own main partition). One heading has 979MB the other just 1.4MB (that must be the formating info)

but why does it HAVE to show as two HD?

on my pc it shows only as one external HD. But on my mac it shows as two external HDs. Does it mean that I have to reformat it in order to show as "one" HD on my mac?
