Thanks for all the replies, I am waiting on the next ISO to download 
before I burn another CD. The key components of my system are as 
follows (all 1-3yrs old).

Motherboard: Abit KT7A-RAID/AMD 1.1GHz/1G ram
/dev/hde: Maxtor 6L080J4  (master)
/dev/hdf: Western Digital WD102AA (slave,  /tmp)
/dev/hdg: Maxtor 5T040H4 (master)
/dev/scd0: YAMAHA CRW2100E (really on hdc as master)
No drives attached to hda, hdb, or hdc

Executing hdparm on each drive:
#/sbin/hdparm -c3 -d1 /dev/hde
/dev/hde:
 setting 32-bit IO_support flag to 3
 setting using_dma to 1 (on)
 IO_support   =  3 (32-bit w/sync)
 using_dma    =  1 (on)

# /sbin/hdparm -c3 -d1 /dev/hdf
/dev/hdf:
 setting 32-bit IO_support flag to 3
 setting using_dma to 1 (on)
 IO_support   =  3 (32-bit w/sync)
 using_dma    =  1 (on)

# /sbin/hdparm -c3 -d1 /dev/hdg
/dev/hdg:
 setting 32-bit IO_support flag to 3
 setting using_dma to 1 (on)
 IO_support   =  3 (32-bit w/sync)
 using_dma    =  1 (on)

# /sbin/hdparm -c3 -d1 /dev/scd
/dev/scd0 not supported by hdparm
**scd = hdc!
# /sbin/hdparm -c3 -d1 /dev/hdc
/dev/hdc:
 setting 32-bit IO_support flag to 3
 setting using_dma to 1 (on)
 IO_support   =  3 (32-bit w/sync)
 using_dma    =  1 (on)

I will let you know if this helps,
