Interfacing an IDE hard drive

Does anyone know how to interface an IDE hard drive? I don't know the pin layout (of the connector) or how to write/read data. It's an old Western Digital.

Thanks

for hw interfacing take a look at this page ...

https://www.pjrc.com/tech/8051/ide/

it shows how to interface an IDE drive using microcontrollers.

I know that new HDDs have built-in temperature sensors, so, how do I extract this information from the HDD?

Self-Monitoring Analysis and Reporting Technology (SMART)

In an effort to help users avoid data loss, drive manufacturers are now incorporating logic into their drives that acts as an "early warning system" for pending drive problems. This system is called Self-Monitoring Analysis and Reporting Technology or SMART. The hard disk's integrated controller works with various sensors to monitor various aspects of the drive's performance, determines from this information if the drive is behaving normally or not, and makes available status information to software that probes the drive and look at it.

Thanks, but if I had a microcontroller interfaced to the HDD, what commands must be sent to request the information and how must it be interpreted?

you can google for those mp3 projects, usually consisting of IDE interface for hard drives:

I suggest you to read the following book and the FAT16/32 specs from Microsoft

The SCSI Bus and IDE Interface
