Table 1-2. HP C2244/45/46/47 OperatinQ Specifications (continued)
External Data Transfer Rate (Host/Controller)
Narrow Single-Ended/Differential _
Asynchronous .................. , .................................... 2.5 Mbytes per second
Synchronous ................................................. up to 10.0 Mbytes per second
Wide Differential
Asynchronous ....................................................... 5.0 Mbytes per second
Synchronous ................................................. up to 20.0 Mbytes per second
Recoverable Data Error Rate
Less than ten (10) errors in 10
13
bits transferred when the disk drive is operated within the
specified environmental limits.
Note: A recoverable data error occurs when a read or write operation successfully completes
with the execution of a recovery algorithm. The recovery action is reported to the host with a
Sense Key of 1. (Refer to the Request Sense command in Appendix A.) Mode pages must be in
the factory default states.
Unrecoverable Data Error Rate
Less than ten (10) errors in 10
15
bits transferred when the disk drive is operated within the
specified environmental limits.
Note: An un-recoverable data error occurs when a read or write operation does not sucessfully
complete with the execution of a recovery algorithm. The unsuccessful operation is reported to
the host with a Sense Key of 3. (Refer to the Request Sense command in Appendix A.) Mode
pages must be in the factory default states.
Seek Error Rate
Less than ten (10) seek errors in 10
7
seeks when the drive is operated within the specified
environmental limits.
Note: A seek error occurs when the drive does not successfully locate the desired cylinder and
head.
Recording Density
Bit Density: .......................................... 1968 bits per mm (49,987 bits per inch)
Track Density: ....................................... 91 track.s per mm
(2304 tracks per inch)
Coding System ............................................ 1,7 Run Length Limited (RLL) Code
Electromagnetic Emissions
Current Electromagnetic Compatibility (EMC) regulations do not specify or require testing at
the component (standalone) level since EMC is highly dependent upon the characteristics of the
system in which the product is installed.
Although regulatory testing is not required, these products have been characterized as
individual components using Hewlett-Packard standardized tests.
