3.5" inch External USB Floppy Disk Drive for Laptop PC Portable 720KB/1.44MB FDD

[orange]

Has anyone tried one of this:
3.5" inch External USB Floppy Disk Drive for Laptop PC Portable 720KB/1.44MB FDD (eBay link: http://www.ebay.com/itm/3-5-inch-External-USB-Floppy-Disk-Drive-for-Laptop-PC-Portable-720KB-1-44MB-FDD/131326612317?_trksid=p2141725.c100338.m3726&_trkparms=aid%3D222007%26algo%3DS)

Would it be possible to use this drive plus a Windows based ADF creator/editor to convert my old floppies into adf that I can later use with my NG Amigas?

no, from what I've heard USB drives can only use 720K or 1.44Mb. you need expensive catweasel, or better, cheap 2floppy mod, or LPT hack.
but, those can't work on laptop.
