Add -g0 between -v300 and -i4 to include only the first side in the image.

(2 sides x 40 tracks x 9 sectors x 512 bytes)/1024=360ko

I guess you don't need single sided mode but only the first 40 tracks!
So does it also happen if you set -e41 to -e39 in your command line? If there is no copy protection there is no need for the tracks 40 and 41...

Re: convert 360ko dump with a 360ko drive
It could be due to the drive being 40-track and generating data on so-called halftracks (odd tracks) that would show as empty when dumping such disks with 80-track drive. DTC being programmed with 80-track drives in mind sees data on every track and assumes it to be a 720k disk.

What's the drive type you're using. Is it 40 track (48 tpi) or 80 track (96 tpi)?

Re: convert 360ko dump with a 360ko drive
Okay, I checked it myself with a 40 track drive and I have to admit that I can't get it right either. DTC only produces 360k image files if you use a 80 track drive (setting the "track distance" to 40)!
However, if you have to convert al lot of dumps you may use the HxC-Tool which does it right...

aaah i'm not alone 
i think it's a bug because the second half of img is only fill with 00 bytes
