SCP is aimed at duplicating your disks and I have started with 5 rev then had issues with 1 rev and now use 5 rev again for my backups. I also have a Kryoflux board and this defaults to 5 rev. I would recommend using 7zip to compress your SCP dumps as this saves considerable disk space and makes uploading to the retrobackup.com quicker.
Dumps look good. Many thanks for uploading them. Look forward to the remainder.

JimDrew wrote:Are you cleaning your drive heads frequently while dumping? You should be. The magnetic media did not fair well over time and it will collect on the heads, making them "dirty". This results in incorrect data being read.
JimDrew wrote:It's pretty obvious if the flux is bad just by loading the image into the analyzer and looking at a few tracks. I am working on a routine right now that will check the flux as the disk is copied and report if the flux ends up outside of +/-5% of the expected bitcell region.

Q-tip and alcohol?
I'm curious, is there a better way to clean them?
