Hi Linda,
Are you having variable transfer rates based on the zone access point?
If this is the case it is correctly reporting slow on the ID of the LBA
range v/s the OD on the media.

To un
Again, the math
says it's a rate near 5. So it still doesn't make sense.

According to hdparm, dma was already on. It was also suggested I try
setting
32-bit mode and multcount (which I had tried before and not noticed much
difference).
Here's the current settings and results. Note that the timings still don't
make
alot of sense when comparing them to the vmstat numbe
check if DMA mode is still on, on your hard drive. I'm trying to remember if
that behaviour changed for 2.2.17

I just booted an Inspiron 5000. PIIX4. So in the kernel config, read
the help on PIIX support and make sure to turn on 'use dma by default'.
...And you probably still want to at least try Andre's patch.

Off the top of my head it sounds like you are using the wrong ide i/o

What nonsense. There is nothing special with extended
Some further information in response to a private email, I did hdparm -ti
under both
2216 and 2217 -- they are identical -- this may be something weird
w/extended
partitions...
/dev/hda:
multcount= 0 (off)
I/O support = 0 (default 16-bit)
unmaskirq= 0 (off)
using_dma= 1 (on)
