Replace a 5 1/4" HDD with a 3 1/2" HDD?

Apple iMac "Core 2 Duo" 2.4 24-Inch (Al) Specs

Identifiers: Mid-2007 - 24" - MA878LL - iMac7,1 - A1225 - 2134

The HDD on my iMac died. Your replacement guide states to replace with a 3 1/2" HDD but the drive I removed is a 5 1/4". What gives. Does this mean different hardware to mount this 3-1/2"? Does it Have to be a WD. I just happen to have a 3-1/2" Seagate Momentus 5400.6 500gb drive sitting here. Can I use this drive in my iMac. I noticed yesterday it does not appear to support S.M.A.R.T. I hooked it up to my MBP to check it out and erase it. To prep for install to the iMac.

Main question is 5-1/4" to 3-1/2" replacement.

Thank You

Please give us the last three figures of your serial number (located on the bottom of the stand). Thanks

There are no numbers, just the sticker that states "Designed by Apple" "this item must accept interference from..." etc....

Any other place to look?

Thank you Joshua, will that work into the iMac with the snap-in bracket?

Oh, and Mayer, I bet you've never seen a Commodore 64 with external 5-1/4 floppy drive. There's no need for assumptions and statements like that! Maybe stating a large hard drive replaced by a small hard drive would have been more appropriate.

Just sayin', but thanks for the precision.

Of course I've seen (and used) a Commodore 64 . I bought my first Apple in 1979.

The hard drive that comes in your model actually measures 5 3/4 " x 4" x 1".

It is called a half height drive or a 3.5" drive.

The reason comes form early hard drives that were very large.

http://en.wikipedia.org/wiki/Hard_disk_d...

The standard laptop drive is called a 2.5" drive, and actually measures 2.75 in × 0.275–0.59 in × 3.945.

UPDATE

Here's how to install your hard drive, I would install it and use your original system installation DVD to format it, you can then use Migration assistant to transfer the data from your laptop via Target Mode: iMac Intel 24" EMC 2134 and 2211 Hard Drive Replacement

You can almost always switch from a 5 1/2 to a 3 1/2, but, depending on the application, often times you will need an adapter like this one here. As you can see they are quite inexpensive.

Good luck!

My bet is that you've never seen a full height drive. The Quantum Bigfoot HDD was the last to use it in the late 1990s.
