Hello, I have tried to solve this problem trough several ways, along several days, but this is impossible for me. When my computer boots, this message is showed: "Initializing VFBACKUP device. Protection Windows Error. You must reboot the computer. System stopped" After this I cannot restart in safe mode. I only can restart with the emergency diskette and entry in MS-DOS mode. I have all my data and directory there, and I can navigate and run some "no-windows" executable programs. Scandisk not find any problem in the fixed disk, and the fans run correctly. I have restored a previous system version running SCANREG...... Nothing. The last thing that I did before error shows, was a CD-Copier program installation. ¿Some problem with a driver o IRQ? Perhaps, but I d´ont know how I can solve it. When I boot in "Step by Step" mode, the error appears after give OK to the Mouse driver... and apperas when I denied the drivers as well. I hope somebody had this error before me... and perhaps wouldn' t necesary re-install Windows or (AAAAGH)... format the fixed disk. WHAT CAN I DO? HELP PLEASE !!! Thousands thanks in advance.

hello too early to reformat yet. you still have a few good options to try. it looks like the error mesage is for a old type tape backup starage device.i could be wroung i take it you dont use main frame or net work server type back ups? ok i,m posting a link on some good things to try in your case it will have info on scanreg /restore ect. m.e wont start http://computing.net/windowsme/wwwboard/forum/30687.html

Thank you Dave for your help. I found very interesting your suggestions, and specially useful the reference page linked from you. There were a lot of excellent ideas there. But I have try all of them and my computer doesn´t work. I cannot start in Windows. I will try re-install Windows-Me again and so, if the problem remainds... But lot of thanks for your help, you are very kind. "Saludos".
