Maxtor PowerMax is a small tool which you can test your hard disk like really. The POWERMAX.EXE utility is designed to perform diagnostic read/write verifications on Maxtor/Quantum hard drives. These tests will determine hard drive integrity. The POWERMAX.EXE utility is effective on all ATA (IDE) hard drives with a capacity greater than or equal to 500 MB. Maxtor recommends the use of this utility for troubleshooting potential hard drive problems. These problems include, but are not limited to the following:

- Potential hard drive surface problems (e.g., bad clusters, bad sectors, partitioning/formatting problems, etc.).
- Drive recognition problems (e.g. hard drive that is not recognized by the operating system).
- Software removal.

Note: PowerMax will not detect ATA or SATA hard disks connected to embedded or add in RAID controllers, NVIDIA Force 4, VIA KT 600 and KT800 chipsets. If the hard disk is connected to an unsupported controller, it will have to be moved to an alternate system, or controller for diagnosis. Please check the PowerMax download page periodically for updates. Beginning September 1st 2006 all versions of PowerMax prior to v4.23 will no longer be supported.
