This isn't really a Centos question but it affects the systems so I'll ask here anyway. I've noticed when swapping disks around on IBM 3550 boxes that some of them see one more cylinder on drives than others but I can't find any settings or differences that might control this. It's an obvious problem when you fdisk/format on the one that sees the additional cylinder, then move or copy this disk to one that doesn't. Does anyone know what controls this or if it is just a hardware or firmware version difference? -- Les Mikesell lesmikesell at gmail.com
