Step 2. Open STRCDC.INI in notepad.
Step 3. Search for a setting called (no quotes) "Rewritable_Support=1"
Step 4. Then change the 1 to 0 and save.
Step 5. Make new recovery discs that you need so much...
NOTE. I booted and did this with the Ultimate Boot CD for Windows, if it doesn't work within your local copy of XP just boot a copy of that or a Live Linux Distro..
