looks like this is very rare... any help appreciated...

Aren't these just standard 1GB / 2GB QIC-Wide tapes? On the main auction sites I see a number of IOMEGA branded ones listed in the States, but also a number of Sony branded ones (QW2GB) which carry the IOMEGA DITTO 2GB mark, listed in the EU.

do you think it is stnd qic?
need to check - i saw google images where tapes were labeled DITTO TAPE.
and i remember i had such dedicated tapes. I had.

I'd be amazed if it didn't 😀 - recognise this?

it is not so easy...

DITTO 2GB can R only some of the QIC tapes, 3020xl/f can be R/W, what is strange it can R/W 3.7GB tape even it is only 2GB drive?

I saw that table too, but the point I'm making is that the DITTO 2GB format was a joint development between IOMEGA & Sony (as detailed in the previously posted Free Library article link) and that their respective units are identical, save for individual company branding. To emphasize that point look at the labels on the bottom of their external models (IOMEGA on the left and Sony on the right);

aside from the near identical labels, they're both model IO2000-PX.

I'm as certain as I can be that the pre-formatted Sony tapes I mentioned earlier - QW2GB - will work fine in an IOMEGA-branded unit, and they seem available cheaply enough to be worth a try, but the choice is yours.

I think the only marketing difference is that IOMEGA made an internal & external DITTO 2GB but Sony (possibly) only made an external version of their StorStaion DITTO 2GB.

looks like you are right, hope it will fit to my model...
- i have the internal drive - IO 2000 Wi

I had an Iomega Ditto (not quite sure of the model), running on the Ditto Dash controller

QIC-Wide in 3020 format, though I believe on a slower interface, it may have to drop to 3010 mode (half capacity and speed) if the floppy controller lacks 1 megabit (2.88 M ED disk) support.
Assessing compatibility, I'd actually bought some 3M MC3000 XL tapes (in 3010 340MB format) which could be reformatted to 3020 format for 670MB real (double that in the compressed capacity notation the Iomega use).
At the upper end, I had a TR-3 Extra (2.2GB uncompressed, 4.4 in their notation).
NB. Support for floppy interfaced tape drives ended after Win98, definitely not in XP, don't know about ME and 2k

I have that same sony storstation and a 2GB tape. Will that work? It was given to me, so i never even used it.
