disk defect?

Konrad Hegner — Fri, 27 Feb 2004 06:59:30 GMT

I have some HP disks which sporadically show problems.
I need method to stress the disk (e.g. destructive RW test) and sort them out.
I know the 'dd' command, but if there other methods?
Thanks Konrad

Hi,

Wiping the disks might be a good test. I know its done with dd, but a good thread to look at:

If you have Diagnostics installed, you can run stm. There is an option to exercise the disk from the information menu for cpu.

mstm or xstm or stm as Cheryl mentions is the best way to test the hardware.

EMS can also work but it sometimes gives false warnings.

if dmesg /var/adn/syslog/syslog.log shows lbolts, have a relacement ready to roll.

Hi,

there is also mediainit, which formats and looks for bad spots.
