Removal and Replacement Preliminaries
Maintenance and Service Guide
4–3
Before handling a drive, ensure that you are discharged of 
static electricity. While handling a drive, avoid touching the 
connector.
Handle drives on surfaces covered with at least one inch of 
shock-proof foam.
Avoid dropping drives from any height onto any surface.
After removing a hard drive, CD-ROM drive, or a diskette 
drive, place it in a static-proof bag.
Avoid exposing a hard drive to products that have magnetic 
fields, such as monitors or speakers.
Avoid exposing a drive to temperature extremes or liquids.
If a drive must be mailed, place the drive in a bubble pack 
mailer or other suitable form of protective packaging and label 
the package, “FRAGILE: Handle With Care.”
4.4 Preventing Electrostatic Damage
Many electronic components are sensitive to electrostatic 
discharge (ESD). Circuitry design and structure determine the 
degree of sensitivity. Networks built into many integrated circuits 
provide some protection, but in many cases, the discharge 
contains enough power to alter device parameters or melt 
silicon junctions.
A sudden discharge of static electricity from a finger or other 
conductor can destroy static-sensitive devices or microcircuitry. 
Often the spark is neither felt nor heard, but damage occurs.
An electronic device exposed to electrostatic discharge might not 
be affected at all and can work perfectly throughout a normal 
cycle. Or the device might function normally for a while, then 
degrade in the internal layers, reducing its life expectancy.
