We used this disk for several years as a boot disk for Windows. It performs very well with Windows XP.
Unfortunately this disk did not last very long. The 5V TVS diode failed leading to the demise of the disk.
We replaced the disk with a larger capacity model and using this disk as a backup until it failed. The ST3500320AS which failed after 24,655 hours which did hurt MTBF values in our reliability study.
Lucky for us the disk was still still under warranty. Seagate replaced this disk with the ST3750525AS. We own serveral hard disks, we have long ago learned to use backups of the backups. DVD disks are cheap, and now Blu-Ray are even bigger in capacity. Zip files can be burned to DVD.BD and they are safe.
We have upgraded power supplies after determining that the 5V TVS diode failed. We suspect that transients may have affected the part. Power supplies in 2008 were still comparatively crude and cheaply designed.
