A hard disk drive (HDD), hard disk, hard drive or fixed disk is a data storage device used for storing and retrieving digital information using one or more rigid ("hard") rapidly rotating disks (platters) coated with magnetic material.
HDDs are accessed over one of a number of bus types, including as of parallel ATA (PATA, also called IDE or EIDE; described before the introduction of SATA as ATA), Serial ATA (SATA), SCSI, Serial Attached SCSI (SAS), and Fibre Channel. Bridge circuitry is sometimes used to connect HDDs to buses with which they cannot communicate natively, such as IEEE 1394, USB and SCSI.
or follow to 25 MODERN hardware pinouts.
- 3.5 inch micro Floppy Disk Drive connector (26 pin) micro conector (26x1)
- ATA (44) internal This connector is mostly used for 2.5 IDE HDD of notebooks and so on. Pins 1-40 are the same as the IDE/ATA 40 pin connector, but the spacing between pins is smaller and they are therefore electronically, but not physically compatible.
- ATA (50) internal This connector is mostly used for 2.5 IDE HDD of laptops and some other device. Equal to ATA (44) connector, except 50 pin connector used.
- ATA (50) internal pinout a 50 pin cable will fit most 2.5" IDE drives and bring the extra (master/slave etc) drive pins back to the system board. The connector has the same 2mm pitch as a 40 or 44 pin cable. The only place I have seen this cable is in a Fostex DF-4 Portable 4 track recorder, but it may exist in other places. It is nearly documented at http://paulski.com/zpages.php?id=1717 but he missed the two missing pins at positions 5 and 6. It seems there are a few ways 2.5" IDE drives are wired.. They will all be a subset of.. 40 pins for data 4 pins for power and optionally 6 pins 1 blank row (2 pins), and 4 pins for master/slave.
- ATA 50 to 40 pin (notebook CD-ROM) This adapter will enable you to connect a 50 pin CD-ROM data cable to 40 pin ATA bus.
- ESDI ESDI=Enhanced Small Device Interface. Developed by Maxtor in the early 1980?s as an upgrade and improvement to the ST506 design.
- ESDI cable The ESDI interface requires two cables, one for control and one for data. The control cable is shared between the two drives.
