How can I perform a surface check?

Hi folks,

I have a low level corruption on one of my hard disks. Is there a command that does a non destructive surface scan of the disk?

I'm using HP-UX 11i...

Thanks in advance.
Matthew

Hi Matthew:

# dd if=/dev/rdsk/cXtYdZ bs=10k of=/dev/null

...will read and report any errors.

Regards!

Hi,

no Norton Disk Doctor for HPUX (hear this Symantec ;)
An alternative is "dd if=/dev/dsk/c0t9d0 of=/dev/null bs=51200" which will read the whole disk.
You should have installed Predictive. Predictive will warn you in time when a disk start producing errors.

regards,
Thierry.
