OP states that drive "does not register in BIOS." So it can't be formatted.
Easiest tests: 1) Try another microSATA drive with same connector, or
2) buy a connector from a company with a wider reputation and try that.
Odds are that either the drive or the connector be wonky.
Dumb question: Did you connect the power lead of said adapter to power?

Any links to Micro-Sata to Sata connection with Molex 4 pin is wrong, you'll need this: http://www.digitalintelligence.com
Micro-Sata needs 3.3 volt, and all molex cables supply 5 and 12 volts. This setup requires no power conversion as SATA power cable supports 3.3, 5, and 12 volt. Check the Wiki on SATA. The above is the cleanest you can get in terms of conversion.
