Define correctly. I don't receive any suspicious messages in the
log, there is no obvious data/file corruption that I can tell, and
hdparm now reports DMA as on, and reports the following statistics:
/dev/hda:
Timing buffer-cache reads: 128 MB in 2.56 seconds =50.00 MB/sec
Timing buffered disk reads: 64 MB in 8.44 seconds = 7.58 MB/sec
[root@wr5z /root]# hdparm -tT /dev/hdb
/dev/hdb:
Timing buffer-cache reads: 128 MB in 2.54 seconds =50.39 MB/sec
Timing buffered disk reads: 64 MB in 6.43 seconds = 9.95 MB/sec
Relevant dmesg extract:

Beyond that, I'm not sure what to look for. Are there any other
tests/statistics I should get?
