- IDE
-
- Imbedded or Integrated Drive Electronics. This drive type was
- introduced in late 1989 and early 1990. It was soon discovered that
- the design had a difference in timing and was very susceptible to a
- wide variety of errors including data corruption, failure to boot,
- etc. A work-around for this timing problem was implemented in the
- April 9, 1990 release of AMI BIOS. Any machine containing an IDE
- drive and AMI BIOS dated 1989 or earlier should be upgraded to at
- least the 1990 version.
-
- IDE drives are designed to run with a BUS speed of 8Mhz and will
- not operate properly at any other speed.
-
- IDE drives have a basic interface card (paddle card) that goes
- into a slot in an AT class machine and serves as a bridge between the
- drive and the computer. It is not a HDD controller. the actual control
- electronics are on the drive itself.
