Re: Sending arbitrary ATA commands?

Peter --

I just got an enhancement request (via Radar) to add an API to ATASMARTLib to grab the ATA Identify Data. For some reason, I didn't include this in the original API. I will be adding it to the next major OS release and will probably implement it and push it out to Darwin in the next few weeks.

Hi all,

I'm currently working on a Darwin port of smartmontools. Right now, I'm using ATASMARTLib to enable SMART & read the relevant data and thresholds (thanks, Chris S., for pointing out this framework!) So far, so good. I ported over a bunch of the Linux SMART ioctls over to IOKit ....

One thing the Linux version of smartmontools does is send ioctls to the ATA devices to access the ATAIdentify structure. It heavily relies on this struct throughout the code to determine drive capabilities, model, etc. The raw BSD device drivers don't support these ioctls. Anyways - I worked with this stuff before in MacOS 9 & it was simply a matter of sending the appropriate ATAManager commands. I had a good dig through the list archives but I can't find anything on this subject.

My question: is there a framework for sending arbitrary ATA commands or something for accessing the familiar ATAIdentify structure?

Regards,

Pete C
