Does this mean anything to anyone?

The disks are Seagate 160GBs:
hda: ST3160023A, ATA DISK drive
hdc: ST3160023A, ATA DISK drive

The machine is a dual
model name      : AMD Athlon(tm) MP
stepping        : 1
cpu MHz         : 2000.474
cache size      : 256 KB

with 1GB RAM ...

So is that good?  I don't really care because I ran on one disk for 6
days last week when hdc failed with a loose power cable ...
