2 Medalist XE Family Product Manual, Rev. B Note. Some DOS and BIOS pairings can limit the accessible hard disc capacity to 528 Mbytes. These systems do not acknowledge more than 1,024 cylinders in the translation geometry. If more than 1,024 cylinders are specified in the System Setup, the system may ignore the additional cylinders or overwrap the initial 1,024 with the additional cylinders. In an overwrap condition, only the overwrapping cylinders are used to determine the drive capacity. The overwrap condition for the ST3660A is: 1,057 - 1,024 = 33 cylinders for 17.3 Mbytes. There are several solutions for this limitation: • Use a BIOS that supports logical block addressing (LBA) or extended cylinder-head-sector (CHS) addressing. • Use a host adapter that supports more than 528 Mbytes. • Use installation software or a software device driver that allows access to the drive's full capacity to install the drive. 1.2 Physical organization Heads Discs ST3295A 2 1 ST3660A 4 2
