Hi. I'm reformatting soon and back when I did my original installation of Windows 7 I forgot to turn on ACHI mode in my bios. I have my 1TB Caviar Black partitioned for 250gb Windows 750gb Storage. Will I have to partition the 750gb that all of my Storage/backup files are on if I switch to ACHI? Or just the Windows?

Thanks

Switching between ACHI and IDE all data will be erased.

Are you sure? It's perfectly safe to switch to AHCI (which means "Advanced Host Controller Interface") from IDE mode after installing Windows with a simple Registry edit, so I don't see how he'd lose all that data on that partition. In fact, I can switch to IDE mode and back to AHCI mode right now and I won't lose any of my data. After all, it's just a controller interface.

Logistic: I believe it'll be perfectly fine because the partitions were created using a specific format (NTFS) which actually doesn't get created any differently if you're in AHCI mode or if you're in IDE mode. I mean, using AHCI this time around won't have any negative effect on the 750 GB partition.

It can be done, just a registry tweak. See here http://www.ocztechnologyforum.com/forum/showthread.php?69682-Change-from-IDE-to-AHCI-after-Installation

He is asking if his 750 GB will be safe because it was originally created while he was using IDE mode. So now he is formatting and starting over, and he wants to keep this 750 GB partition, but this time he wants to install Windows with AHCI mode enabled. So he's wondering if he will still be able to use that 750 GB partition with AHCI mode enabled.

So of course, the answer is yes: all the data will still be accessible and the partition will still operate the same way. The file browsing performance on the 750 GB partition may even be slightly faster thanks to AHCI.

So he's not asking how to switch from IDE mode to AHCI after installing Windows.

Hey. Thanks for the responses. Fair enough. I just wanted to make sure all my music/backup files stay safe.

They will as long as you don't accidentally format or delete that partition. hehe

I just switched to AHCI this morning on my ssd that was currently IDE.

AND WHAT A DIFFERENCE, ive gotten the biggest increase in performance when now running on AHCI, all i did was disconnect all my harddrives besides the boot drive.

Then plugged my other HDD after windows finished installing no loss of data etc.

What kind of difference? I can't set just my SSD to AHCI, but it's on RAID, along with my two blues in RAID 0.

AHCI is included in the onboard Raid so no need to worry about it.

Another way to word it is like this:

The RAID controller uses the Advanced Host Controller Interface.
