Hi, I have been working more on the Catweasel NorthStar project. After much searching, I have found the source of the apparent sector errors while reading good disks and have prepared a new version correcting the bugs. It can now read both of my test disks and make images without errors. Here is a sample of an image I have made of a disk from 1985 which came with my restored NorthStar Horizon: http://www.geocities.com/lynchaj/CWNS-vintage.zip The CWNS project really could use some testers now. It can only make disk images of NorthStar hard sector single sided double density disks (SSDD). You'll need a working Catweasel to use it. Of course, some highly skilled developers would be greatly appreciated as well. Next up on the agenda: Make program read and process individual sectors rather than whole tracks Support more NorthStar hard sector disk formats (ie, DSDD, SSSD, etc) The program is still not ready for public release so any volunteers will have to request the program from me. Please contact me off list. Thanks! Andrew Lynch
