I connected a Hitachi 4TB USB 3.0 drive to E4200 router using USB but get alert saying it does not support it.

Anyone has a fix or solution for it?

No. This product does not support drives > 2tb unless CISCO provide a new version of the firmware. The problem is that drives > 2tb use "GPT" (guided partition tables)/"Advanced Format" to be able to access more then 2tb with reasonable performance. The firmware for this device does not support GPT.

Have a look at

would e4200 V2 still have this restriction? If so would it recognize a 1.9TB partition on a >2TB device? Accourding to this site there are at least a couple larger drives that work: Do you have any experience using a powered USB hub on an 4200 V2 router? Would you expect that to be able to work? Thank you.

I am pretty sure USB hub would not work... partitioning a larger drive to 2TB partitions ought to work but I am not 100% sure. – Scott Yu - Front-End UX Feb 26 '13 at 19:32
