Enabling SATA mode on SATA drives in XP
Looks like I'm currently using my SATA drives in IDE emulation mode
through the motherboard. The SATA drives appear under the "IDE ATA/ATAPI controllers" section of Device Manager. All SATA drives appear to be running in UDMA Mode 6 (ATA/133) at present. Question is will there be any noticeable difference in performance if I switch them into SATA mode? Second question, is it worth bothering under XP, when the drives may fail to boot if any change is made? Yousuf Khan |

Second question, is it worth bothering under XP, when the drives may fail to boot if any change is made? There will be no performance difference, and the OS *will* fail to boot. Switching from IDE emulation to AHCI is a pain in Windows. The only real reason to do it is to enable an eSATA port to work properly. |

Yousuf Khan On a new system with XP pro installed, my SATA drives were unbelievably slow in IDE mode - a 1 gig file copy between 2 (real) hard drives took over a minute, maybe 2. Also AHCI mode will allow NCQ to be turned on which speeds up random file access and increases drive reliability (less drive head movements). AHCI mode is worth the effort to enable IMO, however you will need to either install the AHCI drivers at XP installation time using F6 or slipstream the AHCI drivers in an XP CD which is not exactly easy as pie. |

So you're suggesting it is worth the effort for a new installation, but what about for an existing installation? Yousuf Khan |

Second question, is it worth bothering under XP, when the drives may fail to boot if any change is made? Another question, if I were to enable the AHCI/SATA drivers, I'd have to go into my BIOS and turn on Nvidia RAID support, but disable each individual drive as belonging to a RAID set, right?

So you're suggesting it is worth the effort for a new installation, but what about for an existing installation? I have XP running with AHCI. I am not sure what I did, but I think I just installed the controller drivers while still in IDE mode. If I remember correctly, then installing with IDE and then upgrading to AHCI is possible.

Thsi worked for me a few weeks ago on an existing XP installation without having to reinstall the o/s. http://blog.mytwocents.it/?p=11 me/2 Thanks, looks like a fine article. My board uses Nvidia rather than Intel, so I'm going to have to find equivalent analogies. Yousuf Khan |

You mean for hot plugging support? More like hot unplugging. You will be able to attach a drive easily enough, but Windows will not give you the means to safely remove it without data loss. |
