Hi, I am copying from an internal SATA SSD via USB 3 to an external SATA WD Blue, a 3.5" CMR HDD. The first part “cp -ai /mnt/winos7/” (see [*1]) took about 70 minutes for 188 GiB, almost all files are quite small. The second part “cp -ai /mnt/winos10/” (see [*1]) should copy about 100 GiB small files + about 740 GiB for a single vbox vdi file. The about 100 GiB small files were copied and about 310 GiB of the vdi file were also already copied, at 03:30, so for about 410 GiB it took about 9 hours. I think this is taking far too long. Does anyone have an idea? FWIW ^Z was an oversight. I meant to press Ctrl+Alt+T to open a terminal tab, and apparently pressed Ctrl+Z (German QWERTY keyboard).
