Richard,
You said that one rule can override other, but if you read udev
manual ( http://www.reactivated.net/writing_udev_rules.html ), you'll
realize that what you said I think is incorrect.
"Files in /etc/udev/rules.d/ are parsed in lexical order. udev will
stop processing rules as soon as it finds a matching rule in a file
for the new item of hardware that has been detected. It is important
that your own rules get processed before the udev defaults, otherwise
your own naming schemes will not take effect! I suggest that you keep
your own rules in a file at /etc/udev/rules.d/10-local.rules (this
doesn't exist by default - create it). As 10 comes before 50, you know
that your rules will be looked at first. It is important that the
filenames of your rule files end with the .rules suffix, otherwise
they will not be used."
Let me know if I am wrong too? :-)
Leandro.

1. You probably need the ":=" syntax to prevent later rules from
over-riding your settings. For example, in 50-udev.rules, I see:
50-udev.rules:KERNEL=="sd*", NAME="%k", GROUP="disk"
2. You should not have the "/dev/" part of NAME.
3. You probably also need to handle the partitions with the %n syntax
So those rules should be more like:
BUS=="scsi", KERNEL=="sd*", SYSFS{model}=="SAMSUNG SP123245", NAME:="sda%n"
BUS=="scsi", KERNEL=="sd*", SYSFS{model}=="SysOp ", NAME:="sdb%n"
BUS=="scsi", KERNEL=="sd*", SYSFS{model}=="Dados ", NAME:="sdc%n"
You might also consider using LVM on these disks, so you need not care
about sdX, or mounting them by fileystem label.
