Sata how does it work

If it is an entirely new drive, it will appear as Unknown and Not Initialized. Initialize the drive using the following steps. Windows 10 will promptly create a new partition and format the drive ready for use. If you're wondering why I specified unchecking the quick format option, here's why: a quick format doesn't check the drive for errors or damage.

It is preferable to uncover any errors or damage at this stage, rather than when you're trying to upload data or install an operating system. However, if your computer doesn't detect the new drive by default certain BIOS settings will require a tweak. To launch the BIOS, you have to press a hardware specific key before the computer boots into Windows. However, most systems display the correct button during the boot process, before Windows begins to load.

Alternatively, consult our guide to entering the BIOS , including a list of commonly used keys by manufacturers.

Once you're in the BIOS, be careful not to change any unfamiliar options. You may need to toggle an option to "auto-detect new hardware," or specifically turn on the unused SATA port on the motherboard. Carefully check that each cable is well seated in its port at each end and that you haven't accidentally knocked other cables during the process.

If you follow our guide, you should have your new drive up and running in no time and with ease. Now what are you going to do with the old drive? Don't throw it out. Instead, find things to do with your old disk and get a great chunk of good use out of it, even if it's dead.

However, most drives do not use the 3. SATA 2. Pin 1 of the slimline signal connector, denoting device presence, is shorter than the others to allow hot-swapping.

Physical transmission uses differential signaling. When the SATA-link is not in use, the transmitter allows the transmit pins to float to their common-mode voltage level.

When the SATA-link is either active or in the link-initialization phase, the transmitter drives the transmit pins at the specified differential voltage 1. Note the SATA link has no clock line. The sequence also maintains a neutral bitstream, which lets transmit drivers and receiver inputs be AC Coupled. Generally, the actual SATA signaling is half-duplex, meaning that it can only read or write data at any one time, although Full Duplex operation is physically present.

The PHY layer uses the comma character to maintain symbol-alignment. A specific four-symbol sequence, the ALIGN primitive, is used for clock rate-matching between the two devices on the link.

Other special symbols communicate flow control information produced and consumed in the higher layers link and transport. During the link-initialization process, the PHY is responsible for locally generating special out-of-band signals by switching the transmitter between electrical-idle and specific 10b-characters in a defined pattern, negotiating a mutually supported signaling rate 1. During this time, no data is sent from the link-layer. FISs are packets containing control information or payload data.

Each packet contains a header identifying its type , and payload whose contents are dependent on the type. The link layer also manages flow control over the link. Layer number three in the serial ATA specification is the transport layer. The transport layer handles the assembly and disassembly of FIS structures, which includes, for example, extracting content from register FISs into the task-file and informing the command layer.

In an abstract fashion, the transport layer is responsible for creating and encoding FIS structures requested by the command layer, and removing those structures when the frames are received. When DMA data is to be transmitted and is received from the higher command layer, the transport layer appends the FIS control header to the payload, and informs the link layer to prepare for transmission.
