I confirm this bug, a computer I have a prior 8.04 installation in a
partition and:
$ sudo hdparm -Tt /dev/hdg
/dev/hdg:
Timing cached reads: 386 MB in 2.01 seconds = 192.38 MB/sec
Timing buffered disk reads: 90 MB in 3.01 seconds = 29.88 MB/sec
but with the 8.10 installation in another partition... the udma100 mode
is NOT activated, /dev/hdg becomes /dev/sda, hdparm can not change the
dma mode, and working with the hard disk ends sinking the user into
desperation:
$ sudo hdparm -Tt /dev/sda
/dev/sda:
Timing cached reads: 274 MB in 2.00 seconds = 136.84 MB/sec
Timing buffered disk reads: 14 MB in 3.08 seconds = 4.55 MB/sec
