Question/Problem creating a live USB

[JD]

Using liveusbcreator to dump a linux (not of any distro) iso image onto
a 256GiB flash drive (Made by Kensignton).

After selecting the linux ISO image, and setting the
value of the persistent storage, I click Create Live USB.
I get this error message:

Unknown filesystem. Your device may need to be reformatted.


The usb flash drive has partition 1 as a fat32 filesystem. It was
rejected by liveusbcreator with same error message as above.

So, I formatted it as a Ext3 filesystem. Got the same error message.


Next I tried
/usr/bin/livecd-iso-to-disk cd100627.iso /dev/sdc

Verifying image...
/sdb4/Download/OfflineNTpassword/BootCD/cd100627.iso: Could not get pvd data
Unable to read the disc checksum from the primary volume descriptor.
This probably means the disc was created without adding the checksum.Are 
you SURE you want to continue?
Press Enter to continue or ctrl-c to abort
I press enter, and it exits without creating the bootable usb.

So, I tried to use windows and follow the iso creator's instructions to
transfer the iso to flash disk. My winxp-sp3 does not recognize the
drive. And when I try to format the drive,  windows says it was not
able to format the drive.

It is indeed strange that I can format it under Linux, and mount it
and use it the ordinary way. But I cannot transfer the iso image to it.

Any ideas what to do next?

Thanx for your help.
