I've been meaning to make this list for quite some time. Some have windows and dos versions and others only have dos versions. I always recommend to use the dos version so the drive isn't being accessed at the time. So here it is. Western Digital Windows - http://support.wdc.com/product/download.asp?groupid=613&sid=3&lang=en Dos CD - http://support.wdc.com/product/download.asp?groupid=613&sid=30&lang=en Seagate, Maxtor and Samsung Seatools - http://www.seagate.com/support/downloads/seatools/ You can select either windows or dos version. I can't provide direct links to each as they have changed their layout. Fujitsu/Toshiba Windows - http://storage.toshiba.com/techdocs/fjdtwin.exe Dos - http://storage.toshiba.com/techdocs/fjdt_700.zip Must use a dos bootdisk Hitachi Dos - http://www.hgst.com/hdd/support/downloads/dft32_v416_b00.iso All ISO files must be written to cd in order to work correctly. If you don't have burning software that can burn ISO files you can download and install any one of these free programs. IMGburn - http://download.imgburn.com/SetupImgBurn_126.96.36.199.exe [email protected] burner - http://download.cnet.com/Active-ISO-Burner/3000-2646_4-10602452.html cdburnerXP - http://cdburnerxp.se/downloadsetup.exe Or if you have Roxio or Nero already installed, either will work just fine. The ISO files will create a bootable cd to where you can boot to the cd and it will bring up the program. You can run the short test if you want but I always run the extended test to fully test the drive. If you run the short test and it finds errors, it will tell you to run the extended test to fix them. I'll leave this thread open for discussion and editing when necessary. If you have trouble downloading, making the bootable cd or using the program feel free to ask.
