Do you have disconnected it from the motherboard completely? Then this is for you:
Download DisDF.lha from Aminet and install it.
Place these lines in your startup-sequence:
c:disDF 0 -d
assign df0: dismount
assign df0: remove
;DF0: eradicated >:)
Also:
assign cc0: dismount ;ONLY in case you don't use your PCMCIA port, (A600/A1200) you have attached a network card or anything that doesn't use the cc0: device. (Totally optional and unrelated to the subject...)
The benefits of this, are not only that you get rid of the ghosted floppy icon on the WorkBench screen, but most importantly, you stop trackdisk.device from wasting CPU cycles. It does that even if the drive is disconnected.
NoClick patches become obsolete of course. You can remove df0: from the list of hidden devices in the Workbench prefs if you like. (AmigaOS 3.9)

Interesting tip...
As i have a project of removing the FDD in one of my A1200 (desktop) and replacing it with a SCSI zip drive...

To whom it may concern:
I have delete the reference regarding removing the trackdisk.device. It turns out that this causes serious stability problems. The rest of the post is safe. (promise :))

Which in turn means that you don't save any memory or cpu cycles. But oh well, at least DF0 is removed from the doslist.

No, wrong. It does save CPU cycles. I have verified it with Scout. The trackdisk.device stays in memory but in "disabled" state and with its priority lowered at -127.
As for saving memory, i never claimed that. (Although you do gain some memory if you remove it) It's just a slightly better than the standard method to disable the disk drive, that's all..

Great tip! Finally going to get rid of that annoying cc0: for my wee A600.

Thanks for that, AmigaMance. That info came in very handy. I'm in the process of putting an SD card reader in place of my floppy drive and I couldn't figure out how to get rid of that damn "DF0:????" icon.
The only remnant of DF0 is the boot up delay (search for DF0), but I suppose only a custom kickstart could fix that.

You can get rid of the floppy icon by putting a jumper on pins 0-1(or 1-2) i can't remember very well, but it disables the floppy drive and you dont need to touch the startup sequence. I have this on one of my 1200 and works perfectly!!!
