IDE Devices

This section displays information about the IDE devices. Drives are displayed separately for each controller. The following information may be displayed.

Primary/Secondary Controller displays information about the devices attached to the IDE controllers for the selected drive.

Device Type displays the type of IDE device (hard disk, PD-CDROM, and so forth).

Model displays the model of the drive.

Serial Number displays the serial number of the drive.

Firmware Version displays the firmware version of the drive.

Drive Type displays the type of drive. Hard drives vary in the number of heads, cylinders, and other components. The system or client must know the hard drive parameters in order to control the drive. An example of a value that might appear in the Drive Type field is 51, which identifies the Compaq 210-megabyte drive.

Capacity (MB) displays the capacity of the drive in megabytes. For example, 210 identifies a 210-megabyte drive. A megabyte is defined as 1,048,576 bytes. The capacity value shown may differ from the stated size of the drive due to different definitions of a megabyte. Many hardware manufacturers use the value of 1,000,000 for megabyte instead of 1,048,576.

Cylinders displays the number of cylinders on this drive.

Heads displays the number of heads on this drive.

Sectors per Track displays the number of sectors per track on this drive.

Drive Action displays the action that is required for the selected drive. Possible values are:

An error number may also appear in this field. Include this number when reporting a failed drive.

Ultra-ATA Support displays the availability of IDE Ultra-ATA for each device. Ultra-ATA provides quicker drive access times and Cyclic Redundancy Checking (CRC) to validate all data transmitted across the bus. This feature is only available for hard drive devices. The following values are possible.
