View Full Version : WARNING: Kernel Errors Present: EXT4-fs error

I just get these messages in /var/log/mail/root

--------------------- Kernel Begin ------------------------

WARNING: Segmentation Faults in these executables
nm-applet : 1 Time(s)

WARNING: Kernel Errors Present

---------------------- Kernel End -------------------------

The problem is the /dev/sdb. It keeps bangin noise (like the R/W heads banging).
The disk is Seagate Barracuda LowPower 1.5TB 5900RPM SATA2 32M (ST31500541AS)
I have not have problems with read or write so far.

The /dev/sdc is Samsung 750 GB SATA 2 (HD753LJ) with no problems.

So, is the problem with Kernel or is the disk going to die?

Any ideas?

I would suggest to enable the smart function in your bios and start the smartd daemon. run 'smartctl /dev/sdb' to check and observe your disk status for a while. rw heads banging doesnt sound good at all :eek: backup your data from that hdd asap.
