3.1.6 PARTITION
The drive must be partitioned using the system’s FDISK utility. For operating systems other
than DOS, please refer to your OS operating guides. Note that changing the partition
information will erase all data currently on the drive. Refer to your OS manual for information
regarding partitioning a hard disk.
3.1.7 FORMAT
The AT2515 is low-level formatted at the factory, which establishes the 512-byte sector size.
A high-level format is required after the partition has been established on the drive. Refer to
your OS manual for information regarding hard disk drive format procedures.
3.2 JUMPERS
The following diagram illustrates the location of the drive configuration jumpers on the AT2515.
The jumpers control the drive selection - master, slave or cable select. The jumper required is
a 2-pin vertical header on 2mm centers.
