I use a Haas GR510 gantry mill and accidently deleted all programs on it one day while in a rush. I did have a back up floppy, but it doesnt contain any of my new programs resently written. Are the programs on the hard drive? Do I need a Haas Rep? or am I screwed and have to rewrite them again? Any help would be appriated.

try undo you r probably screwed

Files are not usually deleted, the directory name is changed so that the name does not appear and indicates that this space can be used by any new file, so as long as you do not write to the HD or as little as possible, there is a good chance the file still exists, just this directory name has to be restored.
There is shareware and different programs out there that will do it, Norton Utilities should also have a utility that does it.

Bad news, it take 3 keystrokes to deleted something, so that being said your best bet is rewrite those program. Unless you have backup.

On CNC's with I have had success recovering Deleted files using the following Method.

First, You must not have used the Machine for any New jobs. If you have some or all of the deleted files may be lost.

The CNC hard Drive is Ghosted to an Image. ( this means taking the hard drive out, adding it as a slave to another systems, and making a duplicate copy of the CNC drive)

The CNC drive is then re-installed (untouched in the same condition as it was)

The Image is restored to a Secondary Drive.

Deleted files are then recovered from this Secondary drive.
Their are many different programs that can attempt to do this,
I use Forensic's based software for this.

The Deleted files can them be uploaded via rs-232 or Floppy.

Don't attempt to work on the Original CNC drive or you might screw things up worst.

You are screwed! (If you did not have a backup). 'Al the man' is right about program pointers and the smoke and mirrors that can be performed on deleted programs, but face that facts that a lesson has been learned hard way on your part. - MAKE BACKUPS -.

Our company uses a version control revision library system for CNC program storage. It is a system that uses a commercial program revision library that was modified ( by me ) to store the previous version of the program in a library system. The previous CNC program version can be retrieved if needed.

Not to say that it is best system to use, but the fact that our company was one of the top 10 machine shops in the USA in 2006 (according to American Machinist) is not a point to ignore. Sorry, but you have to crow while the sun shines.

vpcnc,

You should give a close look at True Image software for HD Imaging.

Norton (Ghost) software is 'crapware'. Norton (Symantec) tries to take over your entire OS system.
