[solved] mounting usb stick

[MarkGrieveson]

Hello.  I have two usb sticks.  One is 4 GB while the other is 8 GB.  The 4 GB stick is automatically mounted, and appears on the desktop, but not the 8 GB stick.  Anyone have any speculation about this?

open a console log in as root. Then type:
tail -f dmesg

Plug in your usb key. See if there are any errors. You can
also look at lsusb after you plug in the key.

It still is not finding the 8 GB stick (but it does find the 4 GB stick).  I tested the 8 GB stick in a Windows XP machine, and it was found there.

Sorry,

As root

tail -f /var/log/messages

then plug in your USB key.

Do you know what filesystem is used for that USB key?

When I did that, I got the following result, which went on forever until I pressed Ctrl-C:

I think it is FAT32.

I installed usbview, and here's the readout I get from it:

However, as mentioned previously, I can't seem to access it.  It doesn't show up on my desktop or within Thunar.

The problem is with the USB key.

The error may occur if you did not remove the
key properly.

One thing to try would be to run a scan from Windows
to check for any errors on the drive.

The other possibility is to save your data and reformat
the USB key.

I tried scandisk in a Windows XP machine, but it didn't have that program.  I then tried chkdsk, which told me that the stick had no problem.  I also tried the defragmenter, and it said the usb stick did not need to be defragmented.  I made sure to remove it properly.  I also tried a different 8 GB stick, and the same issue occurred.

I'm wondering if my hardware is the problem.  It's only got usb 1, rather than two or three.  Does usb 1 not handle sticks over 4 GB?

[MarkGrieveson]

In retesting stuff, I did discover that the new 8GB stick does in fact work with Vector.  The other 8 GB stick I still can't get to work, however.  It does work in Windows (XP), but not in Vector.  I reformatted it as FAT 32, and tried it, but it still doesn't work in Vector.  Mystery.

I'm going to chalk it down as a faulty stick.  So, this thread is solved.
