4.3.3 POWER ROUTING

Bad power can lead to bad data. To avoid “glitches” or noise on the Vcc and ground

lines, power in the system should be routed so that all peripherals are sourced from the

power supply in a star configuration, as opposed to routing a single continuous supply

line to each device in the system. Routing power in the star configuration, as is done on

most desktop PCs, will minimize the effect on one device’s current draw on another

device. This is key to maintaining data integrity on the AT3515. See diagrams below.

5. MAINTENANCE

No maintenance is required during the normal use of this drive.

If data is to be archived for long periods of time (> 10 years), it is recommended that the

data on the drive be refreshed every 5 to 10 years. The manufacturer of the NAND

PROM devices will only guarantee data integrity for a period of 10 years. Programs

such as Norton Speedisk

, which reallocates all sectors on the drive, or Microsoft

Scandisk, which writes and reads every sector on the disk during its surface test,

achieve this end very well.
