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? /Ole _______________________________________________ Bug-ddrescue mailing list Bug-ddrescue@gnu.org https://lists.gnu.org/mailman/listinfo/bug-ddrescue
