ST3295A. The Medalist 545xe isreferred 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. (You can verify the number of cylinders,sectors per

track and heads and the total number of sectors using the Identify Drive

(ECH) command.) The table below shows the factory configurations.

ST3295A ST3660A

Cylinders 761 1,057

Heads 14 16

Sectors per track 50 63

Formatted capacity (Mbytes*) 272.7 545.5

Total sectors 532,700 1,065,456

*One Mbyte equals one million bytes.

You can use other values to configure the drive provided the following

conditions are met:

•The number of sectors per track does not exceed 256.

•The number of sectors per track and the numberof headssatisfy the

following relationship:

≤

(sectors per track)

(heads)

≤

4,096.

•Thetotal sectors donot exceedthe physicalcapacity of thedrive. You

can calculate the total sectors with the following formula:

total sectors = (logical heads)

(logical sectors per track)

(logical

cylinders).

Medalist XE Family Product Manual, Rev. B 1

Note. Some DOS and BIOS pairingscan limit the accessible harddisc

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 theadditional cylindersoroverwrap the initial

1,024withtheadditional cylinders.Inanoverwrapcondition,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.

•Useinstallationsoftwareorasoftwaredevicedriverthatallows

access to the drive’s full capacity to install the drive.
