Contact Start Stop (CSS)
The drive is designed to withstand a minimum of 40,000 contact start/stop cycles at 40˚ C with 13-25% rela-
tive humidity.
The drive is designed to withstand a minimum of 10,000 contact start/stop cycles at operating environment
conditions specified in 6.4, “ Environment” on page 43.

Data Reliability
Probability of not recovering data ....... 1 in 10
13
bits read
ECC implementation
On-The-Fly correction, performed as a part of read channel function, recovers up to 12 symbols of error
in 1 sector. (1 symbol is 8 bits.)
6.6.4
Cable Noise Interference
To avoid any degradation of performance throughput or error when the interface cable is routed on top or
comes in contact with the H D A assembly, the drive must be grounded electrically to the system frame by
four screws. The common mode noise or voltage level difference between the system frame and power cable
ground or AT interface cable ground should be in the allowable level specified in the power requirement
section.
