I have a HP Ultrium 460 external tape drive that i'm trying to upgrade the firmware on - i ahve downloaded the LTT app from HP's site and downloaded the newest firmware available but i keep getting this error message:

Firmware update failed (wrong revision report: F5CD instead of F63D)

Its the one that the app tells me is for the drive so i'm confused as to why it wont work...

The reason why i'm upgrading the firmware is so that i can use my new LTO 4 tapes with 800GB storage otherwise it just ejects them...
