Ah, foo.  I have 6 systems at home running IDE disks all old and smaller
than 500m.  At work I have 40 clients and 2 servers with IDE disks, many
with more than one disk.  While I've made great efforts to insure cooling
is good I cn also say reliablity has neem that I've only one failure in a
year (really old WD2120).   Most fo the drive are in teh 500m to 4.3gb
range and of the system 18 have disks that were new in last May as I
upgraded a bunch of system for disk space reasons and reused the old 535mb
drives in other systems.  The drive mix includes IBM, JTS, WD, Quantum,
Maxtor and Seagates (mostly).  I can't support you claim IDE is
unreliable though for the other two server we opted for SCSI for maximum 
reliablity and other considerations.

The drives I've had fail over the years (20):

 St506 (3)
 St412 (2)
 St225 (1)
 ST251 (everyone I ever had, 5)
 Micropolus 13xx (head bumper stick, 4).
 CMC (all bad crashes, 3)
 and a few of the really old stepper ST157s.
