To Reformat Hard Drive

If it ever becomes necessary to re-format your OmniTurn G4 CNC harddrive, you must first set the boot-sequence so the computer will boot from the original USB stick. If you have not done so, click here for that procedure. If you need to replace the original USB stick, click here for that procedure.

OmniTurn G4 CNC

When the control boots up to the File Backup prompt, press Ctrl-C instead of y or n and you will drop to the DOS prompt, which will be K:\CNC>

At the K:\CNC> prompt, type: c: then press Enter. You should now be at the C:\RUNFILES> prompt.

At the C:\RUNFILES> prompt type: cd\ then press Enter. Now the prompt should be C:\>

At the C:\> prompt type: dir /p then press Enter. The screen should show the files in the root directory of the USB stick. On the top line of the directory display it must show that the volume label is G498. If the volume label is not G498, the control didn’t boot on the new stick, so go back to the CMOS settings and re-check your boot sequence.

If the volume label is G498, press the space bar until the C:\> prompt comes back, then type: savfiles then press Enter. You should see a bunch of files listed as the configuration, offset, and part program files are copied from your internal drive to the USB stick.

When all the files have been copied the C:\> prompt will return. Type makehd then press Enter. The format program will run. When the format program runs, it will ask if you want to format the drive. You must answer with the whole word YES or it will not format the drive. It will then prompt you for a volume label for the drive. The control’s serial number makes a good volume label, or you can just press Enter to leave it blank.

When formatting a large USB drive such as the Sandisk drive in our current control, it can take a long time for the formatting to complete, and may make you wonder if the computer has locked up. Don't worry, it's doing the job. Just go and do something else until it completes. Once the formatting is done, all the system files, including the ones that were saved by the savfiles command, will be copied from the USB stick to the internal drive. You may want to start this process just before lunch. The C:\> prompt will return when the format is finished.

When the format has finished, as indicated by the return of the C:\> prompt, change the boot-sequence back to make the internal drive the boot drive. You can use this same USB stick to update any of your Omniturns.
