hello guys, i really need some help on this one, a fellow tech went to a client to install a Data Security Kit MX-FR14 into a MXM363N,he told me that he removed the original ROMS and replaced it with the data security roms and put the product key into the MFP, as soon as the MFP rebooted he got Error E7-03, so i went back with him at the client site, tried installing the original roms, and got Error A0-15, i decided to then update to the latest firmware and then put the data security roms back in again, but still the E7-03 wont go away, i then got another HDD from a used MFp and it worked, came up with "Ready to copy"so i ordered a NEW hdd from our sharp dealers,went back to the client today put the new HDD in, same thing happened E7-03, is there some type off preparation i need to do with a NEW hdd from sharp, i thought maybe the hdd would automatically format itself when first put into the MFP,when i use another HDD from a used MFP it works, but not a NEW hdd, HELLLLLLLLLLLLP!!!!!!!!!!!!!, hope i dont get you guys bored with so much typing.
