error

sir ,


[xxxxx.xxxxxx]end_request: I/O error dev sda ,sector xxxxxx.


how to recover it and create backup.
i have tried sudo fdisk-l.

1. Where and when does this error appear?
2. Is it a new problem that has suddenly appeared following a system crash or similar?
3. The command is actually sudo fdisk -l so you missed the space after fdisk.
4. That command does nothing except show the partitions on the disk; it does nothing more.

Run a live system from CD or USB and run the terminal command

sudo e2fsck /dev/sda1

and then for all other ext4 sda# partitions, but not the swap partition.

That command may well report errors and allow you to correct them. Report back here any results, good or bad, and let's see if we can get you up and running again.
