Conclusion

The following results are from formatting the Fujitsu MHV2120AT to FAT32. You may notice the "0%" CPU Utilization figure. Since HD Tach has a +/- of 2%, this could mean the drive was using 2% of the CPU. Since the drive was tested on a dual-processor motherboard (Abit VP6 with 2-1Ghz processors), HD Tach may have been confused. For example, once processor may have been using 0%, while the other processor was using 2%. Depending on the software application, one or two processors may be used. In either case, this demonstrates the very low power requirement of the Fujitsu MHV2120AT.
