The only suitable way to read a disk image is to use a software natively able to understand its format.įor me, I think it doesn't matter. Please understand that, depending on the DOS variant, the way that your script is restoring the image to a fixed byte string may leave the image altered as well. Therefore, they may only be good for an experiment and should always be discarded immediately after. They could be misleading for computing historians. ![]() Depending on the DOS variant, this could make the disk image unbootable and make it hang the computer (or stop the emulator) when booted.įurthermore, altered disk images are no longer genuine and loose their historical value. When modifying bytes in the disk image to make it readable by WinImage (for instance, by adding a BPB), you are overwriting data or code in the boot sector.
