Trying to upgrade capacity of LS421

[LewM]

Hi,

My first post on the forum was likely made to the wrong section.  I will try again:

I bought an LS421DE and initially installed 2x1tb disks.  I now want to upgrade to 2x2tb disks, which I recently bought.  I installed the new disks and expected the OS to go through the initialization process.  Instead, I get an E07 error.  After checking on the web, it appears an upgrade is not a trivial task (!!).  I can't find any info on the Buffalo web site. 

Is it really so strange that someone would want to upgrade capacity?

I would appreciate some suggestions from someone who has done this before.

BTW, I bought the LS421 2 years and 9 months ago (in the USA) and is still in 3 year warranty.  The *&@ support system requires a serial number and it says my system is now out of email support, so I can't even get an email address to ask this question.

You need to press the function button in the front of the device to have it load the firmware from the internal flash memory to the hard drives.  The NAS OS is installed on the disks so without doing this proces, it won't do anything.

If he has E07 with the new disks inserted then he needs the TFTP image to be loaded onto the new disks.
