Covering Index without the data file (myisam)

[Hank]

Hello everyone,

 I know this is a longshot, but is there any way to eliminate the MYD
file for a table that has a full covering index? The index is larger
than the datafile, since it contains all the records in the datafile,
plus a second reverse index.  It seems redundant to have to also store
a MYD file.

Thanks,
