[TriLUG] 4TB GPT Disk fails to Mount with Tomato 2.6.22.19 Kernel

[Alan Sterger]

Hello Listers,

I use Tomato firmware on my USB equipped Linksys E3000 router.  Tomato 
development recently released a kernel update to allow GPT disks (> 2TB) 
to be mounted.

I have a Fantom Drive G-Force3 MegaDisk USB 3.0 Dual Drive RAID 
storage.  The drive contains 2-2TB Advanced Format disks that can be 
configured as RAID-0, RAID-1, JBOD or SPAN (concatenated).  Fantom 
Drives/Micronet uses third-party JMicron JMS539 (ID 152d:2509) 
USB-to-SATA bridge.

Windows Vista detects the RAID-0 (4TB) configured device and initialized 
as a GPT disk using JMicron drivers flawlessly.  Tomato's Linux 
2.6.22.19 kernel does not.  I have tried several different Tomato builds 
with no luck.

I do have the device working as RAID-1 (2TB) formatted as ext3.  But 
would like to have the device's full 4TB capacity available.  The drive 
will be used for short term backup retention.  As I'm in test phase, 
there isn't any data to worry about.

I can PAY someone who suggests successful kernel quirks, I/O parameter 
changes or a complete new kernel that enables Tomato to detect my 4TB 
GPT initialized Fantom Drive.

If interested contact me personally.
