Plug power LED into header labeled "power" and the drive activity LED into the header labeled "activity".Ĭompatibility would be limited to SATA drives that use pin 11 as a drive activity indicator line. Useage would be to plug the newly created "dongle" into the power connector of a SATA drive (or enclosure!), and plug the SATA power connector from your power supply into the dongle. Encapsule the whole thing in rubber and sell it for $5.00. Pin 11, one of the grounds (not tied to the others, from the drive plug end), +12v and +5v would be brought out to a set of 2-pin headers to allow a power LED and drive activity LED to be connected. Im using it to drive 4 WD 100GB 7200RPM SE drives. All of the pins would be carried through, meaning pin 1 to pin 1 and so forth. I have a Promise SX4000 ATA RAID controller, which appears to have connections for only 2 HDD LEDs, while at the same time, supporting 4 drives. See the led light of the hard drive in your notification area. What is needed is a small circuit board with a male SATA power plug on one end and a female SATA power socket on the other.

The drive activity LED is driven from wire #4 (+5v) to wire #2 (pin 11 of the power connector). A quick glance takes you through your drives overall health, temperature, performance, optimization rates, and more.

This alows an LED to be driven from wire #1 (+12v) to wire #3 (floating ground pin). It shows an icon that turns on and off indicating the activity of the hard disk. When the SATA drive is connected to the this "special" power converter, the floating ground is connected to all of the other grounds through the pins of the SATA drive.

Make Sure You Have Enough Space Running a Drive Cleanup Uninstall Old or Unused Software Delete Unwanted or Old Files Manually Check for Viruses and Malware. Note that pin 11 of the SATA power connector is supposed to be "reserved". My guess is that the drive has an open collector output that pulls a load to ground when active, and it is brought out to pin 11 of the power connector. After reverse engineering the "special" power converter that came with my new SATA tray, it seems like the four wires that come out of the back of the SATA power connector and would normally connect to a plug at the back of the SATA tray are:ģ) a ground pin of the sata power connector, *not* connected to all the other ground pins.
