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 AT3515 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 selection jumper on the
AT3515. The jumper configuration controls the drive selection and write protection. The
jumper required is a 2-pin shorting plug on 0.1in centers.
