I've got some old hard drives I'd like to connect to my new computer to quickly transfer gigs and gigs of data from the old drives to my nice large new drives. The old drives are PATA/IDE/ATA and the new computer's motherboard only supports SATA drives.

I found this PCI IDE raid controller card. Will this work? How do I power the old drives. My power supply has only new-style connectors.


I want to do a one-time dump of miscellaneous data (mp3s, DVD images, MAME roms, photos, videos, documents, etc.) off of 5-or-6 smaller, older PATA drives onto my newer, larger SATA drives. I've been unable to "retire" two old computers because I've never gotten around to this housekeeping task. Now I want to get rid of the clutter.


I'd rather avoid the USB solutions. I've got a lot of data to transfer and I want it to go as quickly as possible.

The DVD drive is SATA--not PATA. It's a Dell computer, they don't seem to give away a single extra port on their motherboards. I'm surprised it came with even a free PCI slot.

I've asked: How much slower is USB than SATA or PATA for HDD?


I don't know a power supply model number or anything. It came with a cheap Dell computer. There are no molex power connectors because the computer came with no such drives. The DVD drive is SATA.

I've found adapters, but they go the wrong way: old power supply to new drive.

molex 4pin male to 15pin SATA power cable

This was for a one-time bulk file copy to retire/repurpose the old disk drives and I'm now done. But, I would be interested to know if anyone found such an adapter.

Adapter for Data, adapter for Power –  basszero Sep 18 '08 at 14:37
    
The link in the question, 'How much slower is USB than SATA or PATA for HDD?', is broken. If you're interested, see Bratch's answer to How to measure data transfer speed between my internal SATA HDD and External USB HDD?. Note that the listings are theoretical maximums, you will see lower speeds in real-world tests. –  TonyR Apr 23 '12 at 15:29

I ended up Frankensteining two computers together. I put a PCI PATA card in the new machine for the data connection and got power from a different computer. Ugly.

Ugly but efficient :). –  Terminus Oct 28 '08 at 21:51

+1 for the nice illustration! –  Jon Schneider Nov 5 '08 at 18:30

I can't help noticing the computer on the left is not plugged in :) You could also get one of these usb -> PATA adapters and just use the molex from it, worked nicely for me –  Colin Pickard Dec 1 '08 at 16:22

Well... let's assume there's another power outlet to the left. :) –  Zack Peterson Jan 6 '09 at 14:00
    
This is really bad if there's a ground loop. I'm surprised you didn't fry something. –  Broam Oct 19 '10 at 15:38

The easiest thing to do would be to buy a external enclosure, and use that to power/access the drives.

what about the perfomance hit when transfering over two different interfaces of differing speeds? you have the blazingly fast sata waiting for reads and writes from the slower usb or firewire –  jake Sep 25 '08 at 11:19

@jake: You're already going to have that problem - the old drive is PATA :) –  Broam Apr 5 '11 at 21:33
    
There are many external solutions for caddys to connect to an external/rear motherboard SATA connector. You would have the ease and compatability of an external caddy with the speed of SATA... :) –  HaydnWVN Jan 6 '12 at 11:26

If you are just transferring the data over and you don't plan on using them as drive space in the new machine, I would just get an IDE to USB (and/or Fireware) enclose and put the drives in the enclose. I did that when I went from a PATA box to a SATA box.

I also picked up an USB to SATA/IDE cable. It's handy If I need to diagnose a friend or family member's PC. You can hook that up to a drive while it's still inside another computer and run the USB cable to your machine. There are a bunch of them out there, here's one at Tiger Direct.

Yes, that card should work fine.

What type of power connector does your DVD drive use? It should also work on the PATA drives.
SATA is the same cables, just with a new plug format, so it should be possible to find a simple adapter if you need it.

The downside to this is speed. If you can connect through firewire you should be alright, however, if you have to connect through USB you loose some noticeable speed communicating with the external drive. Also, many of these external cases are not built to run 24/7 so be careful that the one you get has a small fan or some other form of cooling. If you just need to access the drive occasional this is a great way to go (will cut down on drive wear if it isn't hot all the time), but if you want continual access, I'd look into internal options.

What power supply do you have?, because I've never seen any power supply come without at least one of the older 4 pin molex connectors.

If you don't have that you can pretty easily rig something up with your existing connectors if you're feeling a little brave.

There's really no need to get another power supply for this

But if you have old pc's/psu's around it's easier and quicker to hook one of them up. I keep an old AT PSU on my shelf for this very reason, you can also short pin 4 (check this first!) to ground on an ATX for the same result :) –  HaydnWVN Jan 6 '12 at 11:28

I took the second connection from my DVD drive and hooked up an 80gig drive at work, If you can fit everything try it out. I removed my 3.5" and the end of the HD fits perfectly in the whole it left behind, heh.

i'm somewhat surprised no one has suggested an ide to sata connector. the usb to pata way is rather tricky due to the huge difference in speeds. of course this method may mean that you sacrifice the use of your dvd drive while the copying takes place. this is a real hassle too because it involves opening the case and unplugiing stuff.

i have tried this and it was is still a hairy on the seat of your pants experience because most vendors of this product don't give any instructions –  jake Sep 25 '08 at 11:16

Here's a power adapter that goes the right way...

SATA 15-Pin Power Male Connector / Adapter / Converter to Standard Molex 4-Pin Power Female for Hard Drives and Optical Drives

SATA 15-Pin Power Male Connector / Adapter / Converter to Standard Molex 4-Pin Power Female for Hard Drives and Optical Drives

Great for those with new Dell, HP, Compaq PCs that do not include any 4-Pin Molex connectors on their Power Supplies!

If you need to use an older IDE hard drive or optical drive with a new SATA power supply, look no further than xPCgear’s LP4 to SATA power adapter.

2 Simple Answers

  1. Either get a Converter that Converts IDE/PATA Whatever convention you want to call it and get an IDE to SATA Converter for the Data Interface and for the Power

or..

  1. it's just easier to Get an External Enclosure that goes to USB that would fix everything

Why are you answering a more than six year old question which had already 8 answers, one from OP himself, which solved his problem? –  stevenvh Jun 20 at 16:37
