Using laptop HD on desktop, no power felt.
Thanks for all your replies.
The main issue here is to be able to use the laptop. I don't care about data on the drive. To give more clues, here is in more details what I notice. - The drive works when I put it back in the laptop. - Booting the laptop with a different drive, known to boot on another laptop, gives a blank screen with cursor in top left corner, and freezes, probably because wrong BIOS setting since different type/ brand, but BIOS is not accessible. - Booting from floppy or CD fails. BIOS probably bypasses those boots, and is not accessible. - Booting with the original drive brings XP, but asks for password in all cases (safe mode, command line as well). So I can't even just get to a DOS prompt, because I once found on Internet a way to clear BIOS password using DEBUG commands, in the case just a floppy boot would allow to attempt. I did not consider opening the laptop and trying to find the CMOS battery or jumper, because I don't know exactly where it is and don't want to damage anything by accident. I'm also puzzled about the adaptor, why no power is felt. I know laptop drives are quiet, but I really felt nothing, not even a tiny vibration. The adaptor has a 44-hole female end that matches the 44 pins on the laptop drive. However there are 4 more pins on the laptop drive that are not covered by the adaptor, which are separated from the rest by a space. Since IDE is normally 40 pins, I assume the power is already included in the 44-pins covered, and the 4 extra pins (not covered by adaptor) are for jumpers. (Anyways, if this had been power, how would I connect since it's not covered by adaptor?). The other end of the adaptor gives a standard 40-pin male IDE which is into the IDE cable to controller, and there is are extra 2 wires for power that lead to a separate white plastic connector that connects to the standard large 4-hole power connector. However only 2 of these are wired: the red and the black, as opposed to other desktop devices which uses 4 wires for power. I assume it's enough to power the laptop drive. Again, thanks for any advice on the laptop issue, and the adaptor mystery. On Jul 16, 3:00*pm, "Rod Speed" wrote: XYLOPHONE wrote I'm trying to connect a laptop IDE hard drive onto a PC and read it.

Fairly standard. However only 2 of these are wired: the red and the black, as opposed to other desktop devices which uses 4 wires for power. I assume it's enough to power the laptop drive. It is not about "enough" power. It is just that at some time it was decided to have 2.5" drives only use 5V, as that makes laptop design easier. You pay a small speed penalty for that. And it makes everything a bit more expensive. Again, thanks for any advice on the laptop issue, and the adaptor mystery. Can you check that the power conector is actually working? One way is to not plug the adapter into the ribbon cable, just connect the power. The laptop drive should auto-spin then. On the data connection, you can plug this in frongly in two places: - Adapter-to-drive - Adapter-to-ribbon cable. The second option would give power to the drive correctly but would ground several signal lines, which could prevent the drive from spinning. Doing it wrong on both sides prevents the drive from getting power, so also no spin. Incidentially, for some cables (no "nose" on the connector) you can in addition plug it in in the wrong orientation on the mainboard side with much the same effect as the second option. Here is the way to figure out orientation (I know, this is horribly faultu design...): 1. Find pin 1 on the ribbon cable. It is on the side that has a marked wire If that fails, look for the side of the connector that has a nose in the middle. Pin 1 is left if the nose is up and the cable side is away from you. If there is no nose, look carefully, you can often see markings on the connector where it was supposed to be. The other side will be smooth. 2. Find pin 1 on your HDD. On most HDDs it is marked. However the connector is standardized. Place the disk PCB down, top up with the connector towards you. Pin 1 is on the right side. 3. The adapter. This is easiest, pin 1 is on the opposite end from the power connection. If all is connected right, remove the ribbon cable from the adapter and just connect power (allways do this with no power to the computer!) and see whether the disk spins on power up. If it does, try again with ribbon cable. If not, you power connector is likely broken somehow. There will be more steps after this because of the BIOS trouble, but this is first.

Thanks for all your replies. The main issue here is to be able to use the laptop. I don't care about data on the drive. Still not necessarily all that easy if the drive has an ATA password. Certainly the ATA password system does allow resetting of the password with loss of all the data, but it isnt necessarily that easy to rest that type of password if thats what has been set. To give more clues, here is in more details what I notice. - The drive works when I put it back in the laptop. Fine, then you havent killed it. - Booting the laptop with a different drive, known to boot on another laptop, gives a blank screen with cursor in top left corner, and freezes, probably because wrong BIOS setting since different type/brand, but BIOS is not accessible. Nope, more likely thats the result you often get when the motherboard chipset is different to the one that the OS was installed to use. You should be able to do a repair install of the OS to get that drive booting in that laptop. It may well be that access to the bios needs the appropriate stuff on the hard drive in the maintenance partition and that isnt there when you are using a drive from a different laptop. Academic tho as far as being able to use the original laptop drive again. - Booting from floppy or CD fails. BIOS probably bypasses those boots, and is not accessible. Likely due to the same problem above. - Booting with the original drive brings XP, but asks for password in all cases (safe mode, command line as well). Thats normal and has to be done that way otherwise the password is pretty useless. You never did say exactly what the laptop is, that info may well be useful, particularly in deciding whether its using an ATA password on the drive and how to reset that with loss of data on the drive. So I can't even just get to a DOS prompt, because I once found on Internet a way to clear BIOS password using DEBUG commands, in the case just a floppy boot would allow to attempt. You sure its for that particular laptop ? Its pretty unusual for a laptop bios password resetting. I did not consider opening the laptop and trying to find the CMOS battery or jumper, because I don't know exactly where it is and don't want to damage anything by accident. It can be pretty safe with some laptops and not even documented on the net with others. I'm also puzzled about the adaptor, why no power is felt. I bet thats crucial, you should be seeing the drive spin up, tho some laptop drives dont spin up until they get the ATA password. That doesnt explain why no laptop drive spins up in the desktop tho, the other laptop drives dont have any password set, so should spin up in the desktop. I'd concentrate on this because its almost certainly the problem. I know laptop drives are quiet, but I really felt nothing, not even a tiny vibration. Yeah, thats the correct way to check, you should be able to feel it spin up even if its too quiet to hear. The adaptor has a 44-hole female end that matches the 44 pins on the laptop drive. However there are 4 more pins on the laptop drive that are not covered by the adaptor, which are separated from the rest by a space. Since IDE is normally 40 pins, I assume the power is already included in the 44-pins covered, Correct. and the 4 extra pins (not covered by adaptor) are for jumpers. Usually correct. What is the drive model number from the sticker on the drive ? (Anyways, if this had been power, how would I connect since it's not covered by adaptor?). Also correct. The other end of the adaptor gives a standard 40-pin male IDE which is into the IDE cable to controller, and there is are extra 2 wires for power that lead to a separate white plastic connector that connects to the standard large 4-hole power connector. That last is what I called the molex connector. However only 2 of these are wired: the red and the black, as opposed to other desktop devices which uses 4 wires for power. Thats normal. Laptop drives only need 5V, they dont use 12V which is the other colored wire. The two black wires are ground. I assume it's enough to power the laptop drive. Should be, but all the evidence suggests that the laptop drives arent getting any power since none of them spin up when used on that adapter. Again, thanks for any advice on the laptop issue, and the adaptor mystery. Its possible the adapter power wires are miswired if you havent used it successfully before. Its more common for the problem to be with the pins in the white molex connector, which holes the pins have been put in. They should be in the holes that match with the red and black wires in the molex connector in the desktop system. The pin useage of the 44 pin connector is here http://pinouts.ru/HD/Ata44Internal_pinout.shtml One possibility is that the 5V line needs to be connected to two pins in the 44 pin connector, both pins 41 and 42. Its possible its only connected to one of them in the adapter. On Jul 16, 3:00 pm, "Rod Speed" wrote: XYLOPHONE wrote I'm trying to connect a laptop IDE hard drive onto a PC and read it.
