180K disk? Never heard of it, can't even find one on Ebay.
You should be able to use 360K disks, but only one side will have data on it . You will not be able to flip such disks to use the other side because that would require a second round index hole to be present .
I assume that such disks formatted in a double sided drive are completely illegible in a single sided drive?
The original 1981 IBM PC had single sided drives that, using DOS 1.0, formatted disks to 160 KB. Later versions of DOS introduced support for double sided disks (320 KB) and higher data densities (180 KB/360 KB). This drive wouldn't have been from an IBM machine though. Possibly from a PC clone.
