Fedora has problems detecting second partition on my customized pendrive. Pendrive's controller is Phision PS2251-61, which I forced to display two devices - one is a USB-CD, and second one is USB-HDD (basically a normal pendrive partition with switched removable bit).
I have checked my drive against many systems/configurations - BIOS, Windows XP, Windows 7, Tomato 1.28 detect properly both virtual cd drive and second, rewritable partition.
On Fedora 17 however, only cd partition is properly detected and mounted as /dev/sr0 - the hdd device is detected as /dev/sdb but it fails to find any partitions on it (there is one vfat).
Here is what i know:

As I said before - all other systems/devices detect my modified pendrive with no problem - any ideas as to why and what should I do?

[ 5810.308190] isofs_fill_super: root inode is not a directory. Corrupted media?
Oh and by the way - yes, the ISO on the drive is not a valid ISO file, yet it boots flawlessly - data is not corrupted neither on CD part of flash nor on HDD.
SOLVED: I used testdisk, it allowed me to wipe the nonsense partition table and create a new one, after that /dev/sdb0 was detected and i mkntfs'd it.
Although it slows down terribly after copying first 500 MB (like, REALLY slows down, copying few MBytes and stops for 5 secs in cycles), it is recognized by all machines.
I will investigate speed problem further and keep this topic updated.
Also - please move it to the hardware section, seems that I was waaay to tired at night.
Thanks!
