Page 9: Specification Summary
ST3295A. The Medalist 545xe is referred to as the ST3660A. 1.1 Format configuration Seagate Medalist drives are low-level formatted at the factory. You do not need to low-level format the drive. The drives support LBA addressing and are configured in translation mode at the factory. -
Page 10: Physical Organization
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. -

Page 13: Conducted Noise
Medalist XE Family Product Manual, Rev. B 1.7.2 Conducted noise The drive is expected to operate with a maximum of: 150 mV peak-to-peak triangular-wave injected noise at the power connector. The frequency is 10 Hz to 100 KHz with equivalent resistive loads.* 100 mV peak-to-peak triangular-wave injected noise at the power connector. - Page 14 Idle mode, and the Standby timer, if it is enabled, is initialized. If the Standby timer reaches zero before any drive activity is required, the drive goes into the Standby mode. See the Seagate ATA Interface Reference Manual , publication number 36111- xxx for details.
