Buffer i/o error on device sda1

buffer i/o error on device sda1

I am getting a buffer I/O error on dev sda1. It seems to rapidly trigger whenever I use the internet (i.e. every time I type a key into the. # smartctl -a /dev/sda smartctl r [x86_linuxamd64] (local build) Copyright (C) , Bruce Allen, Christian Franke, www. sprers.eu › questions › kernel-buffer-i-o-error-on-device-d. buffer i/o error on device sda1

I do not know too
I/0 error --> something was written and read something completely different (should be the same)
sda1, logical block --> The the moment of silence error is related to the hard disk. ( sda )


You can check what it is sda with
GPartedapp or with gnome-disksapp
and with commands in terminal sprers.eu

Personally, I cannot tell if the error is caused by a hard disk error.
1. You can check RAM

Example memtest with Linux Mint

I use Memtest86 and Memtest86+ from UBCD

3. Check system logs. Check if the error repeats.
You can check on YouTube how use terminal on Linux
You can read how read logs ( journalctlsyslogdmesg )

2. Check errors of hard drive with GSmartControlapp.
- If your hard drive does not support SMART technology. ( then log not exist )
Try to secure important data on the disk first and check the disk with other methods.
Some disk checking procedures may format it ( erase all data on the disk ).

Sometimes the error can also be due to an error in creating a partition.
Or a hardware error. For example, a loose power plug.
Good luck in your search.
