Hi All,
I've got some troublesome readings from two identical hard drives set up the
same. Does anyone know why they are performing so differently? I suppose
hda may be bad, but I was hoping to find some other way to test this. Thanks!

----THE DATA
Here are the hard drives:
hda: Maxtor 52049H4, ATA DISK drive (master ide0)
hdb: Maxtor 52049H4, ATA DISK drive (slave ide0)
Running hdparm I get:
[root@haldane scott]# hdparm -Tt /dev/hda
/dev/hda:
Timing buffer-cache reads: 128 MB in 0.87 seconds =147.13 MB/sec
Timing buffered disk reads: 64 MB in 31.17 seconds = 2.05 MB/sec
[root@haldane scott]# hdparm -Tt /dev/hdb
/dev/hdb:
Timing buffer-cache reads: 128 MB in 0.85 seconds =150.59 MB/sec
Timing buffered disk reads: 64 MB in 2.21 seconds = 28.96 MB/sec
[root@haldane scott]# hdparm /dev/hda
Here are the settings:
/dev/hda:
multcount = 16 (on)
I/O support = 3 (32-bit w/sync)
unmaskirq = 0 (off)
using_dma = 1 (on)
keepsettings = 0 (off)
nowerr = 0 (off)
readonly = 0 (off)
readahead = 8 (on)
geometry = 2482/255/63, sectors = 39882528, start = 0
[root@haldane scott]# hdparm /dev/hdb
/dev/hdb:
multcount = 16 (on)

unmaskirq = 0 (off)
using_dma = 1 (on)
keepsettings = 0 (off)
nowerr = 0 (off)

readahead = 8 (on)
