Jul 20, 2015 · SATA specifies a different power connector than the decades-old four-pin Molex connector used on Parallel ATA (PATA) devices. It is a wafer-type connector, like the SATA data connector, but much wider (15 pins versus seven) to avoid confusion between the two.

Jun 27, 2012 · Those are jumper settings, similar to the IDE drives you mention, but for SATA specific options depending on the drive maker. For example, on this Western Digital support page for mobile drives, it shows two options: Reduced Power Spinup - RPS: Used by external hard disks to reduce spinup current and allows it to work over USB interface.

The new SATA power connector contains many more pins for several reasons: 3.3 V is supplied along with the traditional 5 V and 12 V supplies. To reduce impedance and increase current capability, each voltage is supplied by three pins in parallel, though one pin in each group is intended for precharging.

Jul 25, 2012 · The broad connector on the left is the power supply for the drive, the small connector with the broken pin is for the data. According to Wikipedia those pins have the following functions: 1 1st Ground 2 2nd A+ (Transmit) 3 2nd A- (Transmit) 4 1st Ground 5 2nd B- (Receive) 6 2nd B+ (Receive) 7 1st Ground

May 23, 2012 · Not sure what you mean by "rewiring" or why you think it's necessary. Different SATA connectors can have different numbers of pins, depending on power requirements. Regular SATA is 7+15, yes. Micro SATA is 7+9, just like mSATA, whereas slimline SATA is 7+6. Fewer pins can be used if the disks don't require a lot of power or multiple voltages.

Feb 19, 2016 · I recently bought a 2.5" internal HHD for my desktop computer. During the install I broke the plastic part off the SATA connecter port leaving only the bare pins. For an illustration see below (not the actual HHD): The plastic from that sata connect was then stuck in the SATA cable that had originally broken the plastic piece off.

Feb 3, 2010 · Some SATA drivers have jumpers for extra features, or for troubleshooting. Example from the manual of a Western Digital SATA disk: Set the Jumpers. The default setting for WD SATA hard drives varies depending on the model. To determine the default setting for your drive, look at the drive label on the top of the drive.

Sep 29, 2016 · I knew someone salvaged a drive by taking a SATA cable, stripping off one end, and soldered the cable directly to the plug. The drive worked, but he didn't keep using it. It was just an experiment. This was one of the suggestion you listed, but I …

Mar 25, 2020 · This is how you could connect a SATA drive natively (not through USB) to a host computer. Finally, M.2 is another connector which can deliver SATA signals. The key B version dedicates some pins to SATA signals. (SATA III is a faster version of the original protocol, the number is dropped as everything is SATA III in the last ten or so years.)

Jan 25, 2021 · You have the regular/classic/original SATA connector. That's 7-pin data, 15-pin power. Micro SATA (Not to be confused with mSATA which is Mini SATA). Micro SATA also known as uSATA is from back in the past, when you had 1.8" drives and some (maybe all), had Micro SATA connectors. But 1.8" drives were rare. It was only on those. The 2.5" drives ...
