It's what happens when there's no tape in the drive, or no more
room on the tape, or for whatever other reason, Amanda decides
that the tape has become unusable.  In that case, Amanda tries to
dump as much as it can to the holding disk, and leaves it there
for you to amflush to tape later.

A no-hold DLE is one that has been configured to be dumped
straight to tape, bypassing the holding disk.  If all of this
run's dumps must go to the holding disk, and this DLE must not go
to the holding disk, you can see why Amanda has a problem with
that...

An excellent reason for it to be marked no-hold.

It must be said that they would have sounded better if the singer
wouldn't throw his fellow band members to the ground and toss the
drum kit around during songs.
