The LoaderXpress incorporates many significant improvements in tape drive
and library design. One of the most important is the use of reliable, high-
performance DLT technology, featuring high capacity and long media life.

The LoaderXpress provides three levels of embedded diagnostics:
•
Power-On Self Test (POST) performs verification and memory tests on
the processor’s host interface and device control functions at power-up.
•
User Diagnostics help you change configuration options and control
cartridge movements manually to help diagnose faults.
•
CE Diagnostics are used by Customer Engineers for servicing the
LoaderXpress.

The DLT drive in the LoaderXpress applies a 16-bit parity check to each
record, a 64-bit CRC to each 4kB of data, and Reed-Solomon error correction
code overall. In addition, there is an internal parity check on the data buffer.
