Seagate SeaTools for DOS is a free hard drive testing software that runs independent from your operating system. Seagate provide a iso file which needs to be burned to a CD. Considering that CD/DVD drives are fast disappearing, and most computers these days support booting of a USB drive, it makes life easier if the the iso get converted into USB bootable. It is actually easy to do it on a Mac using the following steps:
a) Download Seatools for DOS from Seagate site (http://www.seagate.com/support/downloads/seatools/)
b) Open the iso file downloaded. Simple double clicking should mount the file on your desktop. Open the mounted folder, and extract the SeaTools.ima to your desktop.
c) Rename SeaTools.ima to SeaTools.img (Accept the warning dialog box)
d) Insert a USB drive that you will use. Note that any data on this drive will be completely erased.
e) Start your terminal window and find the USB drive identifier:
. Make sure that you get the correct disk identifier. In my case it was /dev/disk1.
/dev/disk0 #: TYPE NAME SIZE IDENTIFIER 0: GUID_partition_scheme *500.3 GB disk0 1: EFI EFI 209.7 MB disk0s1 2: Apple_HFS Macintosh HD 249.4 GB disk0s2 3: Apple_Boot Recovery HD 650.0 MB disk0s3 4: Microsoft Basic Data BOOTCAMP 250.0 GB disk0s4 /dev/disk1 #: TYPE NAME SIZE IDENTIFIER 0: FDisk_partition_scheme *16.0 GB disk1 1: Windows_FAT_32 KINGSTON 16.0 GB disk1s1
f) Unmount the usb disk folder using the following commands in your terminal window:
diskutil unmountDisk /dev/disk1
g) Copy the contents of the SeaTools.img file to USB drive
sudo dd if=Desktop/SeaTools.img of=/dev/disk1
That’s it. Your USB drive will now boot to SeaTools. One thing that I have observed with the SeaTools is that if you have set the drives to be discovered through AHCI mode in your bios, it might not always detect the drives. It is better to change the drive detection to IDE for it to work reliably.
For those looking to use the same procedure on a Windows machine, this link should help your out:

One thought on “Convert SeaTools iso file into USB bootable on Mac”
Nice tips, got it done but the Mac can’t recognise the USB at start-up holding down option but still no seatools usb.
Grateful for some feedback.
