Maybe not easy to answer but

Do you know if they is a way or a program to check for bad sectors on the hard disk?

any imput apreciated

IIRC(I don't use it unless debian forces me to at boot), fsck does this. FileSystemChecK(I think is what it stands for). It basically checks the integrity of the disk. Hope this helps.

Start with "man badblocks"

As odd as it may sound, there isn't a lot of point in looking for bad sectors on drives that use Self Monitoring and Reporting Technology (SMART), which is just about any drive made in the last 5 years or so.

The drives autodetect problems with sectors and move their contents to unused sectors on the drive without user intervention or awareness. Modern hard drives also have more capacity than advertised or accessible by the end user.

The extra capacity is used to compensate for bad sectors that develop over time, so the apparent capacity of the drive doesn't decrease. The user never knows that this is going on until the drive runs out of extra capacity.

That's why it's important to monitor drive health with smartd in linux.

thanks for imput, will look into your replys

You can use "dd if=/dev/hdx of=/dev/null" to read the whole of a partition to see if there's a problem with it.
