Keywords: discs high density why not ? Message-ID: Date: 7 Jun 91 07:39:33 GMT Sender: news@cs.man.ac.uk Lines: 21 Hi All, Following on from the question about when Acorn are going to get round to adding a high density drive - what is to stop you just connecting a high density drive instead of the present one. Is it that the 1772 cant cope (if not why not)? Or is the interface different - I'm sure the ADFS or an alternate filing system could be quite easily kludged together. I do seem to remember reading the thing on ADFS_DiscOp that it had a place where it wantd the density - single, double and in the Arthur PRM's it said Quad as well - so what is the problem? Any way what is the difference on a HD disc - more tracks? More sectors? More bytes/sector ?
