I have used IDE ATA cables as long as 36 inches without any problems.  =

the time, so I always thought that was the upper limit.   I didn't have =

and the images.

  Subject: Max IDE Cable Length?


  I purchased some of those new-fangled "round" IDE
  cables the other day.  They're much easier to work with
  and they probably do allow better air flow in the cabinet.

  These cables are 24" long.  I was under the impression
  that the IDE Spec limited cables to 18".  The salesman
  said "I'm sure that they're OK, otherwise no one would
  be making them and we wouldn't be selling them".
  Well, with logic like that I promptly opened my wallet
  and ....

  Has it got anything to do with the old ATA/33/66 vs. the
  new ATA/100/133?  Or the old 40 conductor vs. the new
  80 conductor?  Anyone have any clues about this?

  The system *seems* to work fine.  Perhaps, my data is
  quietly being corrupted, bit by bit ............ :-(
