Hi Ole, Sorry for the late answer, but I'm busy enjoying my vacation. :-)

It looks like Ketil is right: I get around ~50 MB of tar pit and ~150 MB of smooth sailing. Then ~50 MB of tar pit again. The drive is hts545050b9a300 and has 250 GB/platter + 4 heads according to https://www.hgst.com/sites/default/files/resources/TS5K500B_DS_final.pdf Given that I have finite amount of time what is the most efficient way of getting all the data, that is fast to copy, and skip the data, that is in the tarpit?
As ddrescue is currently scraping, and -a only works during the copying phase, maybe a combination of --try-again and -c1 (perhaps with a large --skip-size if the drive is not returning errors) could solve your problem:
ddrescue --try-again -c1 --skip-size=50MB Best regards, Antonio. _______________________________________________ Bug-ddrescue mailing list Bug-ddrescue@gnu.org https://lists.gnu.org/mailman/listinfo/bug-ddrescue
