tb582 Posted March 21, 2009 Share Posted March 21, 2009 I have an adapter thats goes from 2.5" to 3.5" connecting the2.5" side is fine but the 3.5 inch side of the adapter has all 40 pins so the IDE cable has one pin ( i believe #19) blocked off. What are my options here? Link to comment Share on other sites More sharing options...
jaclaz Posted March 21, 2009 Share Posted March 21, 2009 Should be #20:http://pinouts.ru/HD/AtaInternal_pinout.shtmlDouble check it, then you can remove the pin with a pair of pliers or buy another IDE/ATA cable without Pin 20 "blocked", or drill a hole on your existing cable connector (not really advised ).jaclaz Link to comment Share on other sites More sharing options...

submix8c Posted March 21, 2009 Share Posted March 21, 2009 (edited) Red line running down the cable indicates Pin1. Just "pull" the "block" out of the Cable with a safety pin. Some connectors (pins) in some MoBo's and/or HDD's (usually older ones) have A PIN "sticking out" (older) whereas newer Cables have the "pin hole" blocked and no pin present on the MoBo or Device. I have "pulled" this "block" before with no ill effects. Pin1 on the Device is usually right next to the Power Connector and the MoBo usually has a marking on it; "1" on the end for the Red Edge of the Cable to be connected. Also, there is usually (not always) a "hump" on the Cable and a "slot" on the MoBo (or Device) that prevents inadvertantly plugging in incorrectly.HTH (clarification of jaclaz' post) Edited March 21, 2009 by submix8c Link to comment Share on other sites More sharing options...

Your adapter has all 40 pins, right? "The IDE cable has one pin blocked off"... Unblock the cable! Look at the end of the cable - there's probably a "plastic plug" in the hole; pull it out.(got a link to the adapter where purchased?)edit - upper part of pic is the 2.5in. side, and lower is 3.5in. side?(looking for a "blocked cable" in my stash...)Found one I had "gouged out" the plug (I think)... appears to be "that one"...

jaclaz Posted March 21, 2009 Share Posted March 21, 2009 Just to clear what I said (I should know what I have said):you can remove the pin with a pair of pliersmeaning from the adapter.Second advice:or buy another IDE/ATA cable without Pin 20 "blocked"Third advice:or drill a hole on your existing cable connector (not really advised ).The (few) cable connectors with no hole corresponding to pin #20 I have seen were "solid plastic", if yours is a "normal" connector with a "plastic pin" inserted in it at #20, you can of course try removing it. jaclaz Link to comment Share on other sites More sharing options...

Pin 20In the ATA standard, Pin 20 is defined as key and is not used. However, some flash memory disks can use pin 20 as VCC_in to power the disk without needing a special power cable[14].So with that being said I think I'll get a cable without pin 20 blocked, any ideas of where to obtain one?

jaclaz Posted March 22, 2009 Share Posted March 22, 2009 Looks to me like you can just "bend" the pin out of the way...Which was the original suggestion. I mean, it depends on the actual use of the adapter, if it's going to be "portable", you can cut it/bend it with a pair of pliers, this way the adapter will be "compatible with any ATA/IDE cable you may find on different machines.If you get a new ATA/IDE cable with pin #20 unblocked, it is OK, as the cable too will become part of the "portable" kit.If you "drill the hole" (or make a groove with a cutter) to your existiung ATA/IDE cable, besides the possibility of breaking something or hurt yourself, you won't have anything really "portable"."Also, there is usually (not always) a "hump" on the Cable and a "slot" on the MoBo (or Device) that prevents inadvertantly plugging in incorrectly."To ensure that it's plugged in correctly. Both methods apply (second is also a "key")...Please note that whilst the actual connectors are the same, there are TWO kind of cables:old, 40 wires one, up to ATA-5 / ATA 66 if I recall correctly (Ultra DMA modes 0, 1 and 2)new, 80 wires one, for ATA-6/-7 / ATA 100 and 133 (and backwards compatible)Old cables had "exchangeable" connectors, you could plug any of them in either motherboard, master device or slave device.New ones are colour coded:http://www.pcguide.com/ref/hdd/if/ide/confCable80-c.htmlBlue: The blue connector attaches to the host (motherboard or controller).Gray: The gray connector is in the middle of the cable, and goes to any slave (device 1) drive if present on the channel.Black: The black connector is at the opposite end from the host connector and goes to the master drive (device 0), or a single drive if only one is used. @tb582Most cables won't have pin #20 blocked, just check your preferred local store or national internet source, as an example, Lindy cables are not blocked:http://www.lindy-usa.com/31-2-ata33-ide-ha...-45m/33140.htmlhttp://www.lindy-usa.com/31-2-ultra-ata-66...-45m/33156.htmlOn online shops usually there is a picture of the cable, from which you can see whether pin #20 is blocked or not, this one:is an example of the ones that are "solid plastic".jaclaz Link to comment Share on other sites More sharing options...

jaclaz Posted March 23, 2009 Share Posted March 23, 2009 Yep , correction:there are TWO kind of cables:old, 40 wires one, up to ATA-5 / ATA 66 if I recall correctly ATA-4 / ATA 33 (Ultra DMA modes 0, 1 and 2)new, 80 wires one, for ATA-5 / ATA 66 and later ATA-6/-7 / ATA 100 and 133 (and backwards compatible)jaclaz Link to comment Share on other sites More sharing options...
puntoMX Posted March 23, 2009 Share Posted March 23, 2009 Third advice:or drill a hole on your existing cable connector (not really advised ).The (few) cable connectors with no hole corresponding to pin #20 I have seen were "solid plastic", if yours is a "normal" connector with a "plastic pin" inserted in it at #20, you can of course try removing it. I used to push the pins trough the 0.5mm plastic, and yes, I did that many times before without any problems. Older motherboard with just PIO mode or UDMA2 used to have that extra useless pin. if the pin breaks removed it indeed with some pliers by bending it a few times more.Sure you do this with risk of breaking things, just be careful, I don't want to be held responsible .
