I used a SMD desoldering air gun which I set to 100 degrees centigrade and then blowed heat air onto the tape from some distance until it changed from a white matte surface into a darker brown surface. Then it easily came of the tape without damaging the tape. There were some kind of residue left which I used isopropyl alcohol to remove. I also added some lubricant to the tape rollers. This far I have recovered ten tapes successfully. Two tapes only read 128 blocks. I used RT11 to recover the tapes but it seems that the /IGNORE option doesn't skip bad blocks at all. I had the hope that COPY/DEV/FILE/IGMORE DD0: TU58.DSK would skip the bad blocks. But I might be misunderstanding the syntax? I will try to use DUP directly and see if that makes any difference. Something like * TU58.DSK/F=DD0:/I/J But according to the manual it just skip the bad block which is annoying since then all remaining blocks is shifted block number wise. Probably have to manually recreate the structure using dd? /Mattis
