I can't access the image via this link since I don't have a login for that page, but if it's a Fujitsu SMD drive with 14", then it can only by a M2284, M2294 or M2298. They didn't do more models than that with 14" platters. And they indeed have to heads per platter side. http://bitsavers.informatik.uni-stuttgart.de/pdf/fujitsu/disk/M228X/B03P-4580-0100A_M228x_Apr81.pdf Cheers, Pierre
