Problems with ATA hard disk(s)

[Grega Fajdiga]

Good day,

I am a beginner when it comes to Linux, so please bear with me.

I have two ATA hard disks. Proc/../model says Maxtor 91021U2 and ST31722A 
respectively.  The /dev/hda one is  Maxtor 91021U2.  The mainboard model is 
P5I430TX TITANIUM IB and CPU is Intel P200 MMX. Softwarewise I am using 
ReiserFS and 2.4.16 version of the kernel. 
I tried to tune HDD performance, so I put this into /etc/rc.local:
/sbin/hdparm -c1 -A1 -m16 -d1 /dev/hda

When I look at the HDD settings after boot, I see that almost everything is 
turned off:
[root@tm-68-65 grega]# /sbin/hdparm /dev/hda

/dev/hda:
 multcount    = 16 (on)
 I/O support  =  1 (32-bit)
 unmaskirq    =  0 (off)
 using_dma    =  0 (off)
 keepsettings =  0 (off)
 nowerr       =  0 (off)
 readonly     =  0 (off)
 readahead    =  8 (on)
 geometry     = 1245/255/63, sectors = 20010816, start = 0

In the logs I have bunch of such errors:

DriveStatusError BadCRC }

If you need more info, don't hesitate to ask. Please CC me, as I am not on 
the list.
