appendix C HARD DRIVES Compaq Computer Corporation uses IDE/EIDE hard disk drives that conform to two different primary/secondary implementations. These are Conner mode and ATA-compatible mode. These two modes are incompatible with one another. Device 0/Device 1 Relationship A device 0/device 1 relationship exists when there are two hard drives connected to a single port. In this situation, one drive must be designated as the device 0 (primary) drive and the other as the device 1 (secondary) drive.
SMART The hard drives for the Compaq Deskpro 2000 Series of Personal Computers are all SMART compatible. Drives that are SMART compatible have built-in drive failure prediction that warns the user or the network administrator of an impending failure or crash of the hard drive. Automatic Soft-Drive Types An automatic soft-drive type is a mechanism where the system ROM and Computer Setup provide support for IDE/EIDE hard drives that are not supported in the hard drive parameter table.
In order to take full advantage of the higher transfer rates, the standard 40-conductor cable must be replaced with an optional 80-conductor cable. The Compaq Deskpro 2000 Series of Personal Computers will support up to four mass storage devices.
appendix D SCSI GUIDELINES This appendix contains helpful guidelines for installing Small Computer System Interface (SCSI) devices. For more detailed information, refer to the documentation that came with your computer. Guidelines for Installing Optional SCSI Devices When installing and operating SCSI devices, you must adhere to the following guidelines: ■ A single SCSI controller allows you to daisy-chain up to seven SCSI devices.
Termination 1. Every SCSI chain must be terminated at both ends regardless of whether it is an internal SCSI chain, an external SCSI chain, or a combination internal-external SCSI chain. 2. The PD-CD drive must be terminated by using a SCSI interconnect cable that has a terminating plug on one of its ends. This drive does not ship with terminating resistors. 3.
