Btw...what problem do you have?

Make a bootable floppy, copy the utility into it, then boot your computer with the floppy and run the utility from the command-line with the parameters you have already listed.

u can use WD Data LifeGuard Diagnostics from WD website....this sw support all brand HDD.

Or alternatively, especially with these newer computers who don't have a floppy drive, get a copy of DOS (FreeDOS is a good place to start), make it into a bootable CD and add in the utility CD. I know it's a serious waste of space, but hey, CD-R are cheap these days.

Interesting to see this ExcelStor brand. Seems to be essentially a copy (what else from China?) of Hitachi's HDD's. Through Iomega has bought over it. Like everything else China, ownership of more opaque than who owns Lenovo. The factory is in Shenzhen, headquartered in Beijing, but runs its corporate affairs out of a holding company in the Cayman Islands.
