[ttgt]

Hi,

i have a centos os,i need to run fsck recently frequently or it will not load well.

is any way to check the hd health ?

because i wonder it is os/filesystem issue,or it is hardware fail.

Install smartmontools via yum and use smartctl to run checks on your drives.

Hello,

Try this.

smartctl --all /dev/sda

If you HD is not /dev/sda, replace this with the name. You should be able to obtain this via df -h.

This will give you a SMART status of the drive, which I would start there. Do you have RAID on this system?

[ttgt]

no,there is no raid on it.but will smartmontools show all the error if the hd get wrong ? thanx

It will show you the SMART data for the drive. Just run it and see what it outputs.

Hi,it shows with (none) root and can not login now,so,the only way i can do now is use dvd to linux rescue to run the test ? thanx

Hello,

You might be able to run it from the rescue CD. What kind of hard drive is it?

Hello,

Download the Western Digital tool from http://support.wdc.com/product/downl...sid=30&lang=en and test your drives.

Download the .iso, burn it to a CD and then test both drives for any errors.
