Remember at one time you very kindly tried to see if you could modify prog called "Flopsee" to produce a list of clusters. Flopsee was specifically for 720 floppies whereas I was working with 1.4s? Unfortunately despite your endeavours this proved not to be possible.
I have just stumbled across a web page which deals with a Cluster Display Prog which does exactly what I was looking for but although, sadly, there is no download for the program nevertheless the source code in assembler is provided.
I know this thread is closed but given the keen interest you took in my original problem (remember the versions of "Chain"?) just thought I'd bring this to your attention. I'm still running Vista but it doesn't say which version of windows this is targeted at. Not even sure if it makes any difference. I thought I saw something about Windows 2000 but having looked again am unable to find any reference to that version.
See you are still keeping to the fore with resolving everyones problems!
