recommended to maintain proper pin one orientation.

6.4 Software Installation Procedure
With the SC3500 installed, the user can now treat the device as a standard Direct
Access SCSI device. Standard implementation of the SC3500 will include building a
partition table with FDISK and high-level formatting. Low level formatting is not
required or recommended as the drive is low-level formatted at the factory. Refer to
your system documentation for detailed OS installation instructions.
