Feature Request Track Range Filter #60

Closed joshstoik1 closed 11 months ago

joshstoik1 commented 1 year ago

Hi there,

It would be helpful to add a track-based range filter for dump and refine operations as a more user-friendly alternative to the existing --lba-start/--lba-end and --skip options.

redumper already knows the precise track boundaries; it could save users the trouble of having to manually calculate and correctly enter that information themselves. :wink:

Example

Track |   Start  |  Length  | Start sector | End sector
-------------------------------------------------------
    1 | 00:00.00 | 02:48.41 |            0 |      12640
    2 | 02:48.41 | 03:05.74 |        12641 |      26589
    3 | 05:54.40 | 03:34.45 |        26590 |      42684

If a user wanted to refine only the second track for the above audio CD, they could run either of the following:

# Current manual way.
redumper refine [drive stuff] --lba-start 12641 --lba-end 26590

# Proposed automatic way.
redumper refine [drive stuff] --tracks 2

I gave it a thought and I will not be implementing this. Usually when you do advanced repair using refine you target LBA's that are bad. Advanced repair is not track based but LBA range based. There is no other scenario that I see where you will want to omit certain track.
