Hard Drive Diagnostics

I dropped a 2.5" Iomega external hard drive about half a meter.  It has a USB interface, and contains 3 partitions, the last one is a 90GiB NTFS partition.  Some of the files are corrupted to the extent that XP can't delete them, others can be copied without problems.  Scandisk takes a long time to get about 1/4 into phase 2, then exits saying the disk check can't be completed.  Some file record segments are unreadable.  Booting with Hiren's BootCD 8.9, I ran Spinrite, but it will take 500+ hours to complete a level 3 scan.  Norton Disk Doctor crashes while loading.
Currently, I think I will copy what I can with Ddrescue, and get whatever is lost somewhere else.

I would like to use Iomegaware to check on the physical "health" of the drive, but it isn't recognized as an Iomega drive (ie. when right-clicking and choosing Properties, there is no Iomega tab, and Iomegaware has no other interface.
At the moment I cannot reformat the drive to see whether Iomegaware will recognize it.  Any ideas as to why it isn't being recognized, or a suggestion for another tool that can test the drive's physical "health"?

But it will probably only confirm what you already know, that you're shit's broke.
