CORRECTCorrect, very helpful, thanks!APPROVED
INCORRECTThe 44 pin IDC (0.75) male connector at the controller peripherals pic, is left mirrored. Pin 44 are pin 1, 43 are pin 2,etc.
2008-08-27 17:21:00rev. 2INCORRECTHi there, The IDC connector must have 2mm (79mil) pitch rather than 75mil if I'm not wrong. Could you check it, please? Thank you, TomAPPROVED
2008-09-15 02:22:16rev. 2INCORRECTFirst. These connectors have not 44 pin, but 43. The apsent pin is a key, protection from incorrect connection. Second. Male and female connectors should be mirror reflections of each other. P.S. Для русского отзыва о правильности. не знаю как ты делал переходник, но я для этого вынужден был пользоваться исключительно образцами винчестеров обоих форм-факторов и коннекторами к ним. По представленным картинкам совершенно невозможно ориентироваться. "Папу" от "мамы" практически невозможно отличить, они одинаковые, а должны быть зеркальными отражениями друг друга. Левая картинка воюще не имеет никакого ключа. А в жизни он есть, это отсутсвующий контакт (читай выше на англ.)APPROVED
2008-10-15 04:47:02rev. 3INCORRECTCorrect: The 44 pin IDC (0.75) male connector at the controller peripherals pic, is left mirrored. Pin 44 are pin 1, 43 are pin 2,etc. APPROVED
2009-05-25 09:16:15rev. 3INCORRECTAs mentioned before, The 44 pin IDC (0.75) male connector at the controller peripherals pic, is left mirrored. Pin 44 are pin 1, 43 are pin 2,etc. APPROVED

2010-09-21 04:05:35rev. 5INCORRECTThe Device end image is back to front and makes reading it confusing, and the key pin is not missing on the image. If you look at the apple power book pinout and ignore the jumper pins it makes more sense. P.S. Thanks for one of the most usefull resorces on the net APPROVED

2012-08-17 04:26:30rev. 7CORRECTDidn't see any errors, had an adapter that missed the 5volt logic pin (41) and used this to splice the 42 to the 41 as well and got the drive working =)APPROVED

2014-06-11 22:42:03rev. 9ERROR FIXEDYou are missing pin 36 entirely (it's DA2) and your DA0 and DA1 definitions are off by one. Pin 35 is DA0 (Address 0), pin 33 is DA1 (Address 1), pin 36 is DA2 (Address 2.) DMARQ is drive-to-host (left pointing arrow), /DMACK is host-to-drive (right pointing arrow), and /IOCS16 is drive-to-host (left pointing arrow) - during a PIO operation it signifies the data transaction in process needs to be a 16 bit value. In DMA operations, it is never asserted, even though they are all 16 bit. PDIAG is grounded by the cable when an 80 pin cable is installed, or wired through to the drives with a 40 pin cable. SPSYNC:CSEL hasn't been used for spindle sync in probably decades now. It is grounded at the host; if a drive sees this pin grounded and has its CS jumper installed, it is the master/device 0, if it sees the pin floating and has its CS jumper installed, it is the slave/device 1.APPROVED
2014-07-08 02:17:26rev. 10ERROR FIXEDPin spacing listed as 0.75" is incorrect. It should be 0.079" or 2 millimeterAPPROVED
2014-12-16 14:37:32rev. 10CORRECTLooks pretty good to me. Did not look at everything but it answered my questions. Thank youAPPROVED
2015-12-02 14:48:25rev. 10CORRECTI used it when I made the adapter Slim DVD (50pins) to IDE (44pins). It works by laptop. I didn't find any errors.APPROVED

2010-02-23 23:12:42rev. 3MUZAMMAL BaigThe IDC footprint is not 0.75" it is 2mm it is not listed in the list
2010-04-18 14:47:33rev. 3It was silly to have to reference another document for the full pinout so I added the additional pins here.
2010-04-18 15:05:04rev. 5Jeff MathewsCorrection, no one seems to indicate where pin 1 starts...
2010-09-27 22:24:02rev. 6MichaelLine 2 of the text should surely read 'Pin 20 may...' not Pin 19. The diagram above is correct - the text is not.
2010-09-27 22:24:12rev. 6MichaelSurely Special note line 2 should read 'Pin 20 may...' not Pin 19.
2011-03-23 14:29:33rev. 6william eylesThe word closes in Special Note: should be spelt closest. This note is important as it defines the position of pin 1. I verified this to be correct.
2012-09-06 21:31:30rev. 7just corrected a typographical error
2012-10-06 21:47:03rev. 8removed HTML junk in the text
