I'm sorry to cause confusion like that, but I erased the partition table (and the MBR for that matter) to show you how the BIOS detects the stick geometry.

usb sticks can be formatted in two ways.
1) with a partition sector and partitions like a Hard Disk.
(embedded area exists)
2) with no partition sector and no partitions like a Floppy Disk. (no
embedded area exists)
Yes, the layout which was tried looks like the below (1), I did not give (2) a shot yet, since this would force me to have a disk layout that seems utterly pointless for this matter (I think).

Disk /dev/usb: 1042 MB, 1042284544 bytes
33 heads, 61 sectors/track, 1011 cylinders
Units = cylinders of 2013 * 512 = 1030656 bytes
Disk identifier: 0x7867a96c

   Device Boot      Start         End      Blocks   Id  System
/dev/usb1   *           1        1011     1017541   83  Linux

Sorry again for the confusion.
phcoder might be on to something though, please also see his recent mail in this thread.

If you still don't like it, that's ok: that's why I'm boss. I simply know better than you do.
