The ebay ad says its a high density drive, so it should be able to read PC formatted (1.44MB) floppies if the ad is true. I have a 3.5" high density disk drive in my A4000 and could read 1.44MB disks fine after mounting PC0:
From the screenshots it says that workbench version is 34.34, which is Workbench 1.3.3
I just been browsing some forums to find info to refresh some of my old workbench memory.
On one forum I noticed they mention a "transfer to PC" tool that came with earlier wb versions, but this was known to work only with external 5.25" diskdrives.
From what I found, CrossDos is not included in WB1.3. Nor does it work with WB before WB2 (maybe even not before wb2.1)
Crossdos from v7 will also support PC HD-disks (1.44MB), but versions before only supports 720k.
An alternative to CrossDos is a program named MessyDos that can be found on aminet. There are two versions, 1.56 and 1.58. The newest version states that it needs WB2, so you could try 1.56 with WB1.3.
Both versions says they support HD-disks.
But if you can get hold of real WB3.1 disks you wouldnt need crossdos or messydos anyway, since wb3.1 have crossdos functionality anyway.
If you find wb3.1 impossible to buy, I guess they are available as adf files so you could write your own disks by transfering the disk images to your A3000 and use an adf-writer program..
