Formatting mp3 player with fat

[amiga4001]

I am a happy user of a mp3 player with the mediator-spider and the poseidon stack.
Is been recognised and plays and copy,s/deletes 100%.
Problem is when the player get's confused and the disk needs to be formatted with fat16 again.
I can find no program which can recover the player when the disk is not being recognised anymore.
I always have to use a pc to reformat...no fun to let the amiga mount the player again.
Hdtoolbox does't recognize anything on the usbscsi.device and HDinstall does see it but all buttons are ghosted.
Any idea's?

Sometimes the drive doesn't like a mp3 song and hangs.
It reads an error on drive on the screen.
When this has happened iit doesn't show up in workbench anymore no.
Only way to recover then is total format with pc.
