It is true that the data are marked for deletion, but still some data could have lost , the marker could have overwritten some part of the data already.

Get it from your backup and binary log.

Or maybe someone who are familiar with the internal structure can help you, but as I said likely that some data would have been overwritten by the delete mark.

myisamchk is not going to help much other than showing you that there are rows marked deleted.
If you do a recover, you may loose those marked reocrds as well if the recover/repair pack all recoreds in the MYD file and reclaim the unused space, the deleted records are considered as free space.
