hdparm questions on some errors

[Nephlim_rx7]

I'm reading through the forum finding many topics on hdparm, how this may increase performance, etc.

When I run hdparm, should I be attempting to make changes to te settings to /dev/hdb or /dev/hdb1?

I error out when I run it on /dev/hdb1
I successfully accomplish settings change when running it on /dev/hdb

example...

hdparm -c1 -d1 -k1 /dev/hdb1

/dev/hdb1:
setting 32-bit I/O support flag to 1
HDIO_SET_32BIT failed: Invalid argument
setting using_dma to 1 (on)
HDIO_SET_DMA failed: Invalid argument
setting keep_settings to 1 (on)
HDIO_SET_KEEPSETTINGS failed: Invalid argument
I/O support = 1 (32-bit)
using_dma = 1 (on)
keepsettings = 1 (on)


hdparm -c1 -d1 -k1 /dev/hdb

setting 32-bit I/O support flag to 1
setting using_dma to 1 (on)
setting keep_settings to 1 (on)
I/O support = 1 (32-bit)
using_dma = 1 (on)
keepsettings = 1 (on)

Am I too assume that hdparm is to be run on the entire drive - /dev/hdb, rather than the linux parition itself /dev/hdb1??

If thats the case than /dev/hdb has been updated by the looks of the settings thereby making the appropriate changes to the linux partion??

Thanks.

hdparm effects changes on the hard disk -- it has nothing to do with file systems or partitions. That's why attempting to set values on /dev/hdb1 will give you errors while /dev/hdb does not.
