You do not want or need these useless additional 3rd party apps for ImgBurn to work properly.\n\nWhen installing Imgburn, be sure to select "Custom Installation" on the two screens presented (if such an option\/screen presents itself) and un-check the boxes for (to prevent) the installation of unwanted 3rd party apps such as AVG Toolbar & others.\n\nImgBurn - Select "Write image file to disk" - \n\n\n\n\n\n\n3. Boot your system with the SeaTools CD. Run LONG test. You may need to change the BIOS "firing order" of the drives in BIOS to assure that the DVD drive is read first & prior to any internal hard drives. If you are unsure as to how to do this, simply post requesting assistance. We are more than happy to help you.\n\n4. If SeaTools comes up OK, run HDD manufacturer's diagnostics --> Hard Drive Diagnostics Tools and Utilities (Storage) - TACKtech Corp.\n\n\nNOTE: You may have to change BIOS settings from AHCI to IDE.\n\n\nFor SSDs - SSD life - tool for solid state drives health and endurance monitoring\n\nSSDs - SeaTools for DOS can now be used for SSDs.\n\nRegards. . .\n\njcgriff2\n\n\nEDIT: 1 October 2019\n\n\nI checked at the SeaTools site and found that they offer a tool\/app, filename = USBbootSetup-SeaToolsBootable.zip that you can download; run the EXE inside (SeaToolsBootable_RC_2.1.2.usbBootMaker.exe) and create a bootable USB stick for SeaTools with DOS on it.\n\nAs with the CD\/DVD, you will obviously be booting from the media device that you just created - the USB stick. To successfully boot from the USB stick, you MAY require a BIOS "Firing Order" change to ensure that the system looks to the USB ports first for bootable media - before looking to the hard drive or CD\/DVD drive.\n\nIf you require assistance to change your BIOS settings to ensure that the USB ports are first in line during boot-up, simply post your system manufacturer's name and the EXACT model number of the system. The model number can usually be obtained from the sticker found on the case of a desktop PC or from the label on the bottom of a laptop. It is very important to have the correct model number to ensure that you are provided with the correct instructions.\n\nHere is a listing of the BIOS key sequence by system manufacturer. On most systems, you press and\/or tap an F-key repeatedly during boot-up to bring up the BIOS menu.\n\nGet access to BIOS settings & Boot Menu: F-keys\/Hotkeys by System Manufacturer (OEM)\n\nINSTRUCTIONS FOR CREATING A BOOTABLE USB MEDIA DEVICE\nThe SeaTools USB creator app is the first selection on this page (under "Downloads") - SeaTools | Seagate Support US\n\n... and is called SeaTools Bootable \n\nHere is the direct link for the ZIP file download (not sure if it will work or not) - https:\/\/www.seagate.com\/files\/old-support-files\/seatools\/USBbootSetup-SeaToolsBootable.zip\n\nGood luck to you.\n\nPlease post if you have any questions.
