I wonder where I can find a CRT technician to service my 1080's s-video.
Where are you located?
Zoom floppy is purely a device for reading from or writing to original disks. (It'll let you format and rename them very easily, too.) I exclusively use it for creating disks from images I find online when a real disk is the best (or only) way to go. Maybe half a dozen times a year? It's not often. But when I need it, it's dang handy and dependable.
I only use it with an external original 1541-ii or 1571. I've
never been able to get it to write to a
1581 disk, which it is supposed to be able to do. As a result, since the Uii+ now can emulate the 1581, I'll use the Uii+ and a 1581 and write to a real drive that way.
There is always a way...
For regular C64 disks, though? Or GEOS disks? Zoom Floppy has been great. I have an old
Windows XP Thinkpad that I've used for years whenever I have odd tasks to do. I use it for the Zoom Floppy, Amiga Explorer, burn a CD in some funky format or more recently EasyFlash 3 programming. There are still browsers out there that work perfectly with it, too (I like
SeaMonkey, which looks like Netscape Navigator 4, which is so cool). Honestly, I kind of love that old thing for what it provides. I've even bought spare parts for it in the event something should fail some day...
Anyway, as for testing the 1571 drive in theory I don't think it matters if you write or read in 128 mode to check the status of the drive. You could even drop down to C64 mode and do the same thing to ensure the integrity of the hardware. The heads either read/write or they don't as far as I know.
Formatting a disk if you ever get Jiffy DOS all set up is SO easy. If you have to do it in BASIC, it's kind of cumbersome to type out the command but it's not that big a deal for a task you'll only need to do a couple of times a year.
