If you deliberately overwrote the drive with zeroes, it might be hosed and unrecoverable. The hardware should be recognizable by clicking on the Apple icon in the upper left screen, then clicking the 'More Information' button, and the looking at your hardware configuration. If the drive is physically connected and spinning, it should be recognized as the specific manufactured object, and display how many free bytes are on the disk. Disk Warrior is good. So is Tech Tool. None of them may be able to bring back data that was over written multiple times. Perhaps a professional data recovery service could do this. I believe they charge several/many hundreds of dollars to do this and there is no guarantee they can resurrect the data.

Launch Disk Utilities. Perhaps, it will see the drive. Maybe, the drive directory is corrupted. Can you try Disk Warrior? . . . . . . . . . . . . . . . . . . . . . .
