HP DAT8 (C1533a / c1528a) DDS2
The HP DDS-format drives have been developed by Hewlett Packard for data storage drives that build on DAT technology. The DDS-2 drive has 4-GB native capacity, yielding up to 8 GB of stored data and has data compression functionality.
The HP C1539A implements the DDS-2 format. This includes all of the features of the DDS-1 and DDS-DC formats, plus the ability to read and write with much higher
• Reads and writes using DDS-1 and DDS-DC formats when using DDS-1 media
(60 m and 90 m). Has all of the features of the DDS-1 and DDS-DC formats.
• Reads and writes with much higher capacity when using DDS-2 media (120 m).
DDS-2 Drive Environmental Requirements
The DDS-2 drive has the following environmental requirements:
• Ambient Temperature
Operating 5 C to 40 C (41 F to 104 F) Non-Operating –40 C to 70 C (–40 F to 158 F)
Operating 0 km to 4.6 km (0 to 15,000 ft) Non-Operating 0 km to 15.2 km (0 to 50,000 ft)
Operating 20% to 80%RH (non-condensing) Non-Operating 5% to 95%RH (non-condensing) Maximum wet bulb temperature = 26 C
