Replying to both Hal and V1...

I finally just bit the bullet and let "dd" run despite both the "apparent" time issue and the high temp at which my deuced Mac(hina) was running, and when it finally completed I realized that I must have originally run a "bs" much higher than 512, hence the time and temperature differences I was experiencing.

Hmmm... I knew there was a keyboard command, but I couldn't remember it, so I ran sudo kill (dd process #).

Since you posted, though, I tried control-C, but all it did was de-focus my Terminal window; control-option-C, on the other hand, did kill the process, but with this anomalous entry:

(Note: I ran TechTool Deluxe>Surface Scan when I experienced the "anomalous" Terminal behavior, and it didn't return any errors.)

Thanks to you both for your thoughts. smile
