Hi guys.. I'm trying to make a rather advanced batch file.. I have a bootable USB device with DOS 8 and NtfsPro (read/write).. When booting from the USB device I want it to copy the SAM and SYSTEM file from the Windows OS to the USB.. But doing so in a special way.. Example: When booting PC1 from USB it should copy SAM and SYSTEM files and save them as SAM1 and SYSTEM1.. Now I go to PC2 and boot from the USB.. this time it should also copy the SAM and SYSTEM files and save them as SAM2 and SYSTEM2 as I dont want the first one to be written over.. I want the bat file to be able to copy from 10 PC's without any files to be overwritten.. How do I do that? .. I have tried to start a bat file: @echo off ntfspro.exe c: if exist a:\sam9 copy c:\windows\system32\config\sam a:\sam10 if exist a:\sam8 copy c:\windows\system32\config\sam a:\sam9 if exist a:\sam7 copy c:\windows\system32\config\sam a:\sam8 if exist a:\sam6 copy c:\windows\system32\config\sam a:\sam7 if exist a:\sam5 copy c:\windows\system32\config\sam a:\sam6 if exist a:\sam4 copy c:\windows\system32\config\sam a:\sam5 if exist a:\sam3 copy c:\windows\system32\config\sam a:\sam4 if exist a:\sam2 copy c:\windows\system32\config\sam a:\sam3 if exist a:\sam1 copy c:\windows\system32\config\sam a:\sam2 if exist a:\sam copy c:\windows\system32\config\sam a:\sam1 else copy c:\windows\system32\config\sam a:\sam if exist a:\system9 copy c:\windows\system32\config\system a:\system10 if exist a:\system8 copy c:\windows\system32\config\system a:\system9 if exist a:\system7 copy c:\windows\system32\config\system a:\system8 if exist a:\system6 copy c:\windows\system32\config\system a:\system7 if exist a:\system5 copy c:\windows\system32\config\system a:\system6 if exist a:\system4 copy c:\windows\system32\config\system a:\system5 if exist a:\system3 copy c:\windows\system32\config\system a:\system4 if exist a:\system2 copy c:\windows\system32\config\system a:\system3 if exist a:\system1 copy c:\windows\system32\config\system a:\system2 if exist a:\system copy c:\windows\system32\config\system a:\system1 else copy c:\windows\system32\config\system a:\system This bat however, will overwrite the first copied SAM and SYSTEM files .. do I really need to set some kind of GOTO command on the end of each line?

On second thought it would be nice if the copied SAM file would have a name like SAM-TIME_DATE_YEAR .. Then one could make a command like: if exist a:\sam* copy c:\windows\system32\config\sam a:\sam(WHAT EVER THE CMD FOR TIME_DATE_YEAR IS)

The bat below will set a var called YMD, using BIOS. If your NTFS driver allows LFNS you can: copy SAM SAM%YMD% ==================================== ::== YMD8.bat @echo off > d.d >> d.d echo E 0100 B4 2A CD 21 B4 4C CD 21 >> d.d echo N DAY.COM >> d.d echo RCX >> d.d echo 8 >> d.d echo W >> d.d echo E 0100 B4 2A CD 21 88 F0 B4 4C CD 21 >> d.d echo N MONTH.COM >> d.d echo RCX >> d.d echo A >> d.d echo W >> d.d echo E 0100 B4 2A CD 21 89 C8 B4 4C CD 21 >> d.d echo N YEAR.COM >> d.d echo RCX >> d.d echo A >> d.d echo W >> d.d echo E 0100 B4 2A CD 21 88 D0 B4 4C CD 21 >> d.d echo N DAT.COM >> d.d echo RCX >> d.d echo A >> d.d echo W >> d.d echo Q debug < d.d > nul del d.d dat for %%a in (1 2 3 4 5 6 7 8 9 ) do if errorlevel %%a set dat=0%%a for %%a in ( 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31) do if errorlevel %%a set dat=%%a echo Date %dat% day if errorlevel 0 set day=Sunday if errorlevel 1 set day=Monday if errorlevel 2 set day=Tuesday if errorlevel 3 set day=Wednesday if errorlevel 4 set day=Thursday if errorlevel 5 set day=Friday if errorlevel 6 set day=Saturday echo Day %day% month for %%a in (1 2 3 4 5 6 7 8 9 ) do if errorlevel %%a set month=0%%a for %%a in ( 10 11 12) do if errorlevel %%a set month=%%a echo Month %month% year if errorlevel 215 set Year=2007 if errorlevel 216 set Year=2008 if errorlevel 217 set Year=2009 if errorlevel 218 set Year=2010 echo Year %Year% del day.com del month.com del year.com del dat.com set YMD=%year%%month%%dat% ::== DONE ===================================== If at first you don't succeed, you're about average.
