How To Create Bootable USB Disk For Seagate SeaTools For DOS

SeaTools is a well known utility from popular HDD manufacturer Seagate, SeaTools free hard drive diagnostic software comes in two flavors one for DOS and other for Windows OS.

While both hard-disk diagnostic tools are excellent, they are different as SeaTools for DOS is more powerful because it is able to access the disks more directly and natively to diagnose the problem correctly. SeaTools for DOS is provided as a standard bootable .ISO CD disk image but since all modern computers support the easier bootable USB medium, here is how to get "SeaTools For DOS Bootable from a USB drive".

To create a bootable SeaTools For DOS USB Drive follow the steps as below :

  1. Download (Filehosting Mirror's : 8.3 MB) and extract to desktop.
  2. Double-click Win32DiskImager.exe to launch "Win32 Disk Imager" which we use to create the bootable USB disc.
  3. Use the "Folder" icon in "Win32 Disk Imager" to browse the "SeaTools.img" file located in same folder.
  4. Make sure the removable disc is plugged into your computer and you are ready to loose any data on that disk, Click "Write" and let the bootable USB disk creation process start.

  5. Once completed your removable USB disk should have files like the ones below.
  6. Have your computer boot from this newly created SeaTools For DOS usb disk and you will launch directly into the interface as shown below.


file is corrupt

I tested the download and once the full-file sizing 8.3 MB is downloaded everything is working fine !!

downloaded second time, and tried to extracted with not luck, it tried to extract but said it is a brocken or missing file, am using winrar to extract.

Have tried twice downloading bootale USB and allways I have get same message, "the compressed (zipped) folder is invalid or corrupted" please advice

Why use just SeaTools when the "Ultimate Boot CD" includes SeaTools (both CLI and GUI versions), other HDD diagnostics utilities, and wait for it... over 50 other utilities ranging from partition management, cloning, hardware diagnostics and benchmarking and so on.
It's FREE, and updated almost monthly.
And... you can add your own software to it or customise it in other ways.

It writes to the USB drive, but I only have 9 items on the drive when it is finished, not 11 as shown above. And when I use the flash drive to try to boot the offending PC, it just says "Free DOS" and does not launch SeaTools. Unless someone has an answer pronto, I think I'm just going to go out and buy a CD-R. This is a ridiculous amount of work.


It's well documented that the GUI version of Seatools has issues with mouse/keyboard. Even if you use a PS/2 setup.

There is also a text version. It worked for me. 1980's ugly but it did work.

Can you create it as the bootable USB?



See quote from Seagate below:

v1.10 (Text)
Note: If you have system compatibility problems with the v2 GUI version, please use the v1 Text version. It has the same level of diagnostic capability and hardware support. These two versions are updated and released together.

I have the same issue where it stops with the "FreeDOS" message.

My disk is a Samsung PATA disk in an HP Compaq nx8220. No other computer here has PATA support, so I can't test it elsewhere. (And I don't have any CD-Rs handy)

And I saw 10 files including the hidden file "".

Also having the same problem as above. Just getting to "Freedos", and nothing else. Tried three different USB Drives of varying sizes to no avail. Any word on how to fix this?
