Fujitsu Erase Utility

Note: This program works only with any FUJITSU IDE/ATA hard disk drives

This procedure performs a pseudo-formatting to the drive. It erases all of your previous data and reinitializes it to "00" pattern. By performing this task, you will be able to erase the whole user area including your Master Boot Record, Partition Table, FAT (File Allocation Table), and all the files and data it refers to. Use this program if you want to be sure your drive is clean.

Hitachi / IBM

Hitachi / IBM Drive Fitness Test:

Drive Fitness Test (v4.05)
This download creates a self-booting DOS diskette to run the DFT utility. The Drive Fitness Test (DFT) provides a quick, reliable method to test SCSI and IDE hard disk drives. The Drive Fitness Test analyze function performs read tests without overwriting customer data. (However, Drive Fitness Test is bundled with some restoration utilities that will overwrite data).

Maxtor (includes former Quantum product line)


The Powermax utility is designed to perform diagnostic read/write verifications on Maxtor and Quantum hard drives. These tests will determine hard drive integrity. The Powermax 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.

(The utility is distributed as a Win32 utility that writes to a bootable floppy.)

Note: PowerMax v 4.21 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 March 1st 2005 all versions of PowerMax prior to v4.22 will no longer be supported. Maxtor recommends that you update to version 4.22 before testing your hard disk.
