Which utilities are best for doing a copy with verification? I'm familiar with xcopy and xxcopy in XP. I help my sister (less savvy) with her laptop (Vista) and we have fairly new netbooks with Windows 7.

She was having occasional read problems with her external drive (backup, but [thread=2210460]her laptop's hard drive died[/thread]), so I copied it to my netbook. My first try was lazy, using W7 Explorer. It mostly succeeded with an error on only one file, but Windows started complaining about USB 2.0 ports a few minutes later. I retried the copy with xxcopy and figured out that it had errors of varying severity when the USB cable was jiggled. I replaced the cable and completed the copy.

Searching around later, I found this blog post: Windows 7 Explorer may corrupt MP3 files. The copied files are the correct size, but end with zeroes. I deleted the Explorer copy without verifying it, but the intermittent cable issue is pretty similar to the anecdotes.

Look into fastcopy (also free) it actually copy faster than teracopy. Teracopy corrupted my data once.
