What's wrong with having drives named as /dev/sdX ?
Historically SCSI drives were named /dev/sdX, while IDE /dev/hdX.
Since some time ago any hard drive is named /dev/sdX regardless
whether its IDE/ATA, IDE/SATA or SCSI, there is one uniform interface.

Mind that hdparm is a tool which was tailored towards IDE drives only.
It is compatible with old interface (/dev/hdX) but only partially with
the new one (/dev/sdX).

There is no point in doing that.

dmesg will give you all the information you need. It displays kernel
messages (additionally they go to /var/log directory). So you can open
a terminal and try:

dmesg | less

to browse through all the messages. If you want to find out what mode
the hard drive is switched to search (to search press /) for lines
starting with:

ata1 (for the 1st controller) or ata2 (second). In my case I have

[ 0.517229] ata1.00: ATA-7: Maxtor 6L200P0, BAH41G10, max UDMA/133

... a few more lines here

[ 0.572323] ata1.01: ATA-6: WDC WD1200JB-00GVA0, 08.02D08, max UDMA/100

... a few more lines here

[ 0.572362] ata1.00: configured for UDMA/133
[ 0.572365] ata1.01: configured for UDMA/100

Which says what respective DMA modes are enabled for my hard drives.

The change you made is permanent, regardless of the updates.

No It doesn't. However, Preload does not do much from my experience
but it might depend on how much memory you have and how fast the
disk(s) is(are).
