| Post subject: | (Solved) Putting files on Virtual HDDs |
Does anybody know if there is a way to put a file (Stage_2.sys) on a virtual FAT32 HDD partition without using loopback devices (I tried them but they are only good for filesystem formatting and suck for everything else, especially writing files and build automation)? I need a tool of some sort that can do that (both adding and removing files ofc). If you know a way I would be grateful to know. |

I tried editing mtools config file and adding drive d: file="...HDD.img" partition=1, but no luck, partition not aligned, other errors etc... That is definitely not the right way of doing it... This gives me, cannot initialize target, non dos media etc... mcopy -i HDD.img Stage_2.sys ::/ (as you can see no way to specify a partition). Edit: Okay so I figured it out. To anybody in the future: Put this inside your ~/.mtoolsrc drive c: file="/path_to_your/HDD.img" partition=1 (1-4 are valid options) (the drive doesn't need to be labeled "c":) mtools_skip_check=1 To copy a file to your virtual HDD partition use: sudo mcopy Output/Stage_2.sys (your file) c: (your disk) To delete a file from your virtual HDD partition use: sudo mdel c:Stage_2.sys (your_drive:your_file) |

For that, mtools may be a better solution. |
