Windows 2000 Performance Monitor

Setup: Dell Server running Windows 2000 Server with 512mb
ram; 1 hard drive with 2 partitions; O/S on partition 1 /
data on partition 2; 36gb hard drive with 75% free

Is it normal to have the Performance Monitor indicate that
the "Current Bandwidth" is at 100? I've got the Monitor
running with 3 Counters:
1) Bytes Total/Sec stays below 10

2) Current Bandwidth stays at 100

3) %Processor Time stays below 10

Is number 2 something I need to worry about?

Thanks
Kevin
