1541-II: Dirty Harry


Backing up the collection, is causing some permanent damage. Every so often the drive just starts gagging on a disk, so I stop the process and open the drive. I’ve actually started to just leave the case off and move my coffee to the other side of the desk. Majority of the disks don’t have issues, but then there are a few that strip large quantities of their magnetic surface off. I ran out of isopropyl, so I switched to booze (something high proof :)). The strange thing is the booze seems to work better. Less disks are getting trashed. might be for other reasons like stronger better made floppies — or ones that were taken better care of. The majority of these disks are from different people, maybe 1/5 are mine and the others are donations from friends and bulk purchases from other equipment buys from ebay. Does anyone have any suggestions for bulk backup of collections to D64?

I’ve written a few scripts in powershell, to handle the bulk of the work. The script does a directory of the disk, if that is successful it takes the header name, uses that as base filename. Then it copies the directory to a txt file, runs D64copy shows the progress. If I type a name after the script command, it will use that name instead of the dir header. I wonder if there is a way to save the error map from D64copy as well?

1571: The Disk Eater of Doom

TastyFloppy Wow. I pulled out the 400+ floppies, a few disk drives and the ZoomFloppy. While I do my day to day programming work, I run a script with Powershell/OPENCBM and started imaging my collection. So do some work, insert a disk, hit enter then continue.

I got through about 100 floppies and started to notice disk errors popping up. I used my newest drive, which was a 1541-II. So I popped the 1541-II’s lid and checked the head. It was filthy. Got the head cleaner, cleaned it off and continued on. The 1541-II’s are easy to clean. But then I thought.. hey the 1571 has warp mode transfers. faster transfer means done faster..

So I hooked the 1571 drive up, tested the transfer. 1571 versus 1541-II. 1571 wins speed wise.

The second disk I inserted, the copy sounded like power tools in use. Which prompted me to stop the process and check the drive. Looking at the Disk after was a shock. I have never had this happen ever.. that’s a solid groove that you can see through. I’m scared of the 1571 disk eater now..
