If you need to extract or reset an unknown password or perform drive recovery on a Seagate hard drive, use a Serial cable to connect the drive to the DiskSense unit.
Take a minute to familiarize yourself with the Serial cable’s three connectors. On one side of the cable, there are two connectors. Both are 2-pin RX-TX (receive-transmit) connectors. The slightly larger one has 2.5-mm pin pitch and is used for IDE drives. The smaller one has 2-mm pin pitch and is used for SATA drives.
On the opposite side of the Serial cable, there is a 3-pin TX-RX-GND (transmit-receive-grounding) connector. This connector is inserted in the Serial port on the back side of the DiskSense unit.
When you look at a Seagate SATA drive (either 3.5-inch or 2.5-inch), there is a 4-pin jumper block right next to the SATA port.
Connect the 2-mm RX-TX end of the serial cable to the two jumper pins located closest to the SATA port so that the red RX (receive) wire is connected to the pin closer to the SATA port.
Desktop IDE drives have an 8-pin jumper block between IDE port and Power port. For the purpose of this manual, we shall call the pair of pins located closest to the IDE port and used for Master/Slave settings the first pair of pins. The next, second pair of pins is usually used for Cable Select settings. The third pair of pins is the one we will connect the Serial cable to.
Please note that IDE hard drives must be set to Master mode for password extraction and reset or drive recovery. To use the drive in Master mode, place a jumper on the first pair of pins (closest to the IDE port), as shown in the picture below.
Attach the 2.5-mm RX-TX connector to the third pair of jumper pins, as shown in the picture below. Make sure that red RX (receive) wire is facing down and the black TX (transmit) wire is facing up. The second pair and the fourth pair of pins must be left open.
Similar to desktop hard drives, laptop Seagate hard drives also must be set to Master mode to perform password extraction and reset or drive recovery. Master mode on a 2.5-inch device is set by removing all jumpers.
There is a Atola external IDE adapter included in the package with the DiskSense 2 unit.
Use the adapter to connect the drive to IDE interface cable and IDE power cable. Then attach the 2.5-mm RX-TX connector to the left pins vertically, as shown in the picture below. Make sure that the black TX (transmit) wire is connected to the upper pin and red RX (receive) wire is connected to the lower pin.
Once the Seagate hard drive is connected to the unit, follow these instructions to configure the Baud rate of Seagate Terminal, which allows you to use an extensive set of commands on a Seagate drive:
Should there be no output in the Terminal window or should it consist of random symbols, try to change the Baud rate until you get a good response.
Now proceed with password extraction or send Seagate Terminal commands to the drive.
