If want To restore data to original disk you need to repeat the previous step with the correct source(sdb) and destination(sda). 2020-08-23 2019-01-04 2016-07-13 2021-04-05 2021-03-18 Look for entries like sda, sda1, sdb. Under the Linux-2.6 series of kernels this problem may be very neatly resolved . In the descriptions further on, it will be assumed that only one memory stick is present, and therefore mapped to /dev/sda.

clearpart -all -initlabel. ignoredisk --only-use=sda. part /boot --fstype=ext4 --size=500 --ondisk=sda. part swao --size=4096 --ondisk=sda. It's very likely your system drive is sda given the big number of partitions.

But when I try to test the udev rule by udevadm test /sys/block/sdb I see this line in the output: So when Linux initially began to load, the USB hard disk was designated as sdb, and the computer's internal hard drive was sda. However, once my Linux installation had actually loaded up fully, I found that the USB hard disk was now sda , and the internal hard disk had changed to sdb ??? from the df -k command, I see sda, sdb, sdc disks.

List disk partitions in Linux using lsblk command As you see in the above output, lsblk command lists one 20GB disk named sda, with two partitions namely sda1 and sda2.

The disk names in Linux are alphabetical. /dev/sda is the first hard drive (the primary master), /dev/sdb is the second etc. The numbers refer to partitions, so /dev/sda1 is the first partition of the first drive.
