ATA was Standardised by X3/INCITS committee t13 (werd). IDE is simply a synonymous abbreviation. This has to do with Western Digital branding the name IDE (later EIDE) to describe its drives. A standard others conformed to. As of 2003, the offical name for ATA has been changed to PATA (Parallel ATA), to differentiate it with SATA (serial ATA) and to better describe the method of data transfer.

Much to the same affect, the AT Attachment Packet Interface (ATAPI) was another branded standard by Western Digital (I think it is ANSI now) which is now known as the more robust term ATA/ATAPI which simply transcribes the differences between this connection and traditional ATA which was designed fro Hard disk drives only. This is the evolved version of ATA for other perifs basically.

In short, yes, it will work. Hardware wise there are a few more supported features that you will not really need to worry about.

I think this is all accurate, as it is going of some older information from teh brain, and I Did not bother to check the post for accuracy, but it should be close. Being a programming major, I do not know why I remember this, but I remember some of the stupidest <img src="/xxx.gif"><img src="/xxx.gif"><img src="/xxx.gif"><img src="/xxx.gif">.
