AHCI affect old data drive ?

[digitaldreams]

Hi folks

About to install a solid state drive on my system with my old 2TB data drive already in existence...

I have read that AHCI needs to be enabled to gain the maximum performance possible with the solid state boot drive (under Win7-64). My dilemma is that I have seen the problems caused by enabling AHCI after installing Windows AND my bios only allows AHCI to be enabled for ALL SATA2 ports or not at all (current IDE mode instead).

How will AHCI effect my old data drive ?, is it that only boot/operating systems are effected, data drives don't mind the mode change at all ???

Thanks

I've done exactly this swap on the fly, actually post win7 x64 installation, and couldn't notice any difference in the behaviour of the storage drive.

Been using AHCI instead of IDE for the past 2 months.

Just apply the MS fix before enabling AHCI and you'll be hunky dory.

Thanks guys !...will try ASAP.

Hmmm wonder if my 600g Velociraptor and/or 2tb data drive would gain any advantage from AHCI ?

That's a life saver for at work when we upgrade people to SSD, thanks!

Just done the patch and changed to AHCI....no problems so far.

Yet !

I now have my 'USB' (safely eject hardware) icon on my task bar !?. It allows me to 'eject' my hard drives <eeek>. Must find a way to hide the hd options as I use this all the time to eject USB keys & card readers etc...

Beware Philds, your customers could be ejecting their drives all over the place

Good point, I had this once when I bought 2 WD Raptor drives and ran them in RAID0, it's to do with SATA hotswapping. Maybe try disabling SATA hotswap in the BIOS?

Not 100% sure now, as not at home and can't check, but I think you can control the options with tickboxes for that per disk in the Device Manager.

Don't think so !.....seems more complicated. Anyone seen a app to do this automatically ??
