I was told that the logic board need not be removed during this process. It is true?

if you pop open yer iMac, you'll notice that the hard drive, cdrom, etc all lie on top of the logic board, i'm fairly certain that you need not touch the logic board in order to upgrade the hard drive.

Actually, the HD does lie under the logic board half way. I don't know if you do need to move the MB to upgrade the HD though. The installation guide here says yes, but, I can't see why: http://www.theimac.com/drive_steps.shtml

You indeed do need to remove the logic board... it's not that big a deal, the same as if you're installing, RAM, etc...

Once the board is out, you can remove the CD-ROM drive. Below the CD-ROM drive lies the HD, which then also needs to come out and the new one installed in its place.

Like I said, it's similar to installing RAM. If you managed that (or think you can), you won't have any problem installing the HD.

I just referenced the iMac Service manual from Apple... according to the service manual you do not need to remove the logic board to remove either the CD-ROM or the HD.

Well Apple is wrong on that one unless there is some sort of secret enterance on the bottom of the imac

Actually there are plenty of pictures in the service manual which make it quite clear that it' not necessary to remove it. I took out my CD-ROM today just to see if it was possible without removing the logic board and didn't have a single problem.... the HD look easy to remove too. You do need to remove the CD first, but that goes without saying. Then you remove the two screws holding the HD carrier in place and push the carrier back and then up (the same way you remove the CD-ROM).... then it pops right out at an angle.

The reason why I asked this question was that I had received an email from someone a few months earlier cautioning me that the logic board need not be removed as this causes unnecessary additional work and risk to the user and the iMac.

According to the iMac2day site, the boards need to be removed to gain access to the CD ROM and HDD. But according to the pictures on the site, the CD ROM and HDD seem accessible even without the board removal.

Does anyone else have the same experience where the board need NOT be removed to upgrade HDD? Let us know.

I'll tear one of mine apart tomorrow and see if Apple's service manual is correct.... if it is I suppose I may email you a copy of the PDF.... I'm not going to send it to everyone, so please don't ask.

You do *not* need to remove the logic board! I just removed the HD of one of my iMacs, per Apple's instructions.... piece of cake! And a lot less screws to remove! Just watch the little metal tabs on the back of the hard drive carrier. Fishball and Misha If you want a copy of the PDF service manual let me know.

CRE,

Would certainly appreciate if you could email me the copy of the PDF manual. I would really want to look at it and replace my hard disk myself if possible.

Could you let me know what is the brand and spec of HD that you replaced your iMac one with? ATA 33 type etc? Is there anything I should look out for when replacing the HD?

My email is :

THanks
