i am using magic boot disk, when i try to chang the security and press enter for everything else default it checking sum, it said device error. it wouldnt make the changes. why is there a device error? i did it on another HD before and it worked fine. should i be pressing 1 or 2 at the beginning the one with the SCSI adapter supported or not. It didnt make a difference anyways. Also before the disk tries to start up it scans for drivers and such and finds nothing. It is booting through the C:/MHDD. Its not through A:/MHDD. Thats a bad file name or incorrect command.

this is what it says

calculating new checksum...
writing changes to the drive
device error.
