-
- When splitting the channels up into 4 I belive they also lose half the speed.
-
- >The big difference between the two is smarts. Say you have a hard drive
-
- The big difference between the two types are not smarts :), they are of about
- the same intelligens, but the brain of an IDE drive is on the drive making it
- very cheap to implement the controller on a mother board, witch was the whole
- idea.

- >that", set and error code and exit. The IDE drive will say "ok" and
- >(attempt to) send the head out to track 10000, possibly damaging the drive.
-
- This is not true, no drive of today can do any damage to itself, and an IDE
- drive is just as intelligent to handle wild requests as any SCSI drive.
-
- >drives from clueless users that told the system they had bigger drives
- >then they actually did (or otherwise bungled the drive geometry).
-
- They have no idea what they are talking about, they can ofcource get many
- drives back when they send them out for user installation, but that would have
- nothing to do with the way users enter parameters for the drive. My guess is
- that they use that excuse to get costomers to send in their machines for drive
- fitting thereby getting the company an extra income :).
-
- >IDE is really a stickler for drive geometry, it *HAS* to know how the
- >drive is physically laid out. OTOH SCSI converts every read/write
-
- Most current IDE drives have UNIVERSAL TRANSLATE, witch means You can enter
- any drive parameters You like as long as You don't exceed total drive space.
