I should probably include some details about my IDE devices.

here's the controller for the devices in question. it's the second
controller on the mobo. (first controller is only ATA-66)

00:11.0 Unknown mass storage controller: Promise Technology, Inc. 20265 (rev
02)
Subsystem: Promise Technology, Inc. Ultra100
Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr-
Stepping- SERR- FastB2B-
Status: Cap+ 66Mhz- UDF- FastB2B- ParErr- DEVSEL=medium >TAbort-
<TAbort- <MAbort- >SERR- <PERR-
Latency: 32
Interrupt: pin A routed to IRQ 9
Region 0: I/O ports at 9400 [size=8]
Region 1: I/O ports at 9000 [size=4]
Region 2: I/O ports at 8800 [size=8]
Region 3: I/O ports at 8400 [size=4]
Region 4: I/O ports at 8000 [size=64]
Region 5: Memory at de800000 (32-bit, non-prefetchable) [size=128K]
Expansion ROM at <unassigned> [disabled] [size=64K]
Capabilities: <available only to root>

and here's the output of hdparm. (yes, I know it could probably get tweaked
a bit for performance. this is a brand-new drive arrangement, and I was
trying to run it in a 'safe' setting for a while to see if anything would go
wrong. well, it did).

~# hdparm /dev/hde

/dev/hde:
multcount = 0 (off)
IO_support = 0 (default 16-bit)
unmaskirq = 0 (off)
using_dma = 1 (on)
keepsettings = 0 (off)
readonly = 0 (off)
readahead = 8 (on)
geometry = 155061/16/63, sectors = 156301488, start = 0
~# hdparm /dev/hdf

/dev/hdf:
multcount = 0 (off)
IO_support = 0 (default 16-bit)
unmaskirq = 0 (off)
using_dma = 1 (on)
keepsettings = 0 (off)
readonly = 0 (off)
readahead = 8 (on)
geometry = 155061/16/63, sectors = 156301488, start = 0
