Эффект не проявился:
[root@threebears root]# hdparm -d1 /dev/hde
/dev/hde:
setting using_dma to 1 (on)
using_dma = 1 (on)
[root@threebears root]# hdparm -i /dev/hde
/dev/hde:

[root@threebears root]# hdparm -t /dev/hde
/dev/hde:
Timing buffered disk reads: 62 MB in 3.04 seconds = 20.38 MB/sec
Кстати, *udma5 всегда было но обоих винтах. Так что вроде не PIO.
