First: Is the floppy drive in a SE 1/20 capable of read/write 1,44 MB disks?

Second: What software do I need in order it can read/write ms-dos disks?

Third: What does the «Verifying format.......wrong format» when trying to initialize 1,44 MB disks? Is the SE 1/20 floppy drive **REALLY** capable of 1,44 MB disks? (Note: the disks I tried to format in the mac were ok, previously tested in a Windows XP machine with no hassle).

Thanks a lot for a quick response. Regards.
