## NAME

ata\_dev\_read\_id - Read ID data from the specified device

## ARGUMENTS

*dev*

target device

*p\_class*

pointer to class of the target device (may be changed)

## DESCRIPTION

Read ID data from the specified device. ATA\_CMD\_ID\_ATA is performed on ATA devices and ATA\_CMD\_ID\_ATAPI on ATAPI devices. This function also issues ATA\_CMD\_INIT\_DEV\_PARAMS for pre-ATA4 drives.

FIXME: ATA\_CMD\_ID\_ATA is optional for early drives and right now we abort if we hit that case.
