First of all I'd like to say props for all the hard work getting Areca controllers to work.

I'm also using the ARC-1261ML, but I couldn't find firmware version 1.46 (mentioned in the man page) on the areca ftp.  Is it possible for me to get a copy of that?

Or perhaps my "not an ATA/ATAPI device" errors are due to some noob mistake and not the firmware...I'm relatively new to this so bear with me.  I'm using the drives in pass through mode, if that makes any difference.
