Re: Stress testing/burning in HDDs
O/H Don O'Neil ??: I have an array that has a drive that keeps timing out/failing... So I need to replace it. However, I want to stress test/burn in a replacement disk first. What is the best way to do this? ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED] I think that the best way to do this is by using the vendors specific test utility. All known HDD vendors have made utilities to test and find out some basic stats for their products. A very good way to get all the known utilities and much more small usefull programs to test hardware is the Ultimate boot CD. A very nice work has been done and very usefull small programms like memtest, maxtor(sea tools), western digital (dlg diag) etc are included. You can run a surface scan for your disk (that will surely get it to an edge) and find out its temperature, afterwards, and how responds in general. I have been using that for years to find hardware problems. http://www.ultimatebootcd.com/ -- Thodoris ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

It's reasonable to start with something like a: dd if=/dev/your_disk of=/dev/null bs=5120 ...to at least try reading every sector on the drive as a basic sanity check. Better would be to install /usr/ports/sysutils/ smartmontools and run some SMART self-tests via: smartctl -t long /dev/your_disk smartctl even understands some types of RAID controllers, but not all of them -- -Chuck ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

Agreed, but he asked for a stress-test-- arguably, hitting with a size of 512 might be better for that purpose than anything faster. I chose 5120 because many ATA devices seem to have a maximum request/ DMA-transfer size of 16 sectors, and 512 * 10 is convenient and fits under that. -- -Chuck ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
