DVD Burning Program that uses the fast part of the platter?
I use win7 to download linux distros
and ImgBurn to create a bootable install DVD-RW. If I put a 1.5GB .iso onto a DVD, the data is put on the slowest part of the platter. The read speed during install is dramatically slower than if the data were on the fast/outside part of the disk. Is there a burning app that puts the .iso image on the fast part of the DVD platter? |

You don't have to violate any standards. Start reading wherever you have to, but edit in some space, or dummy files. Yes, the app would have to be smart enough to edit the .iso on the fly to modify the file location addresses and pointers. You should be able to do that with a .iso editor, but it's way more work than it's worth. Seems like a nice feature for a DVD burning app. I watched the verification process for the linux burn. Started out at about 2MBPS and was over 8MBPS at 1.5GB at the end...and climbing rapidly. |

You don't have to violate any standards. Start reading wherever you have to, but edit in some space, or dummy files. AFAIK, when you Open the optical disk, the reader starts reading the "lead-in", which is at the inside of the disk. Only after the directory has been read can you jump to any file on the disk. [...] Well, I like the suggestion by "pjp" to try Multi-Session. You might be able to get it that way. The first session will be invalidated, then the head will skip to the second session. I've not played with Multi-Session myself and cannot comment on operational details. You probably have to close_session after the second write. Paul |

I'm not suggesting you move the directory/map. I'm suggesting that the free space be on the slow part and the actual data be on the fast part. Might help to reduce seek time by having an allocation table on the fast part too. [...] Well, I like the suggestion by "pjp" to try Multi-Session. You might be able to get it that way.

While this command has "padding" for the end, it doesn't have that concept or the concept of "offset" for the beginning. https://www.gnu.org/software/xorriso/man_1_xorriso.html The command line for that, is about four lines long on your screen. I've used that command (once) to remaster something. It worked, but the complexity of using it will dissuade you from using it a second time. There might be one of the commercial GUI based programs with such a capability, but I've never used anything commercial for this stuff. Paul |
