[RFE] - a useful sequence: verify

[GoogleCodeExporter]

I often find myself needing to verify a disk (a la Solaris's 
format->analyze->verify), essentially confirming that the disk can write/read 
each sector.

Here's a small patch to allow a "verify" sequence.

Of course, this could be expanded to do two passes (reversing bits, say, with 
"0x00, 0xff" or "0xAA, 0x55").  But I wanted something quick to check some 
drives, and this was it.

Sorry it took me so long to notice this issue.  Good idea - it will be in the 
next release.
