Samsung magician not recognising SSD in AHCI mode.

Hello a few weeks ago I got advice on getting an ssd for my MSI 1761 Laptop and finally bought the 840 250GB.

So here's the deal. I removed my old 750gb hdd and installed the ssd in that slot. AHCI mode is selected in bios. I installed windows and all my drivers etc and then proceeded to download samsung magician. I went through and upgraded the ssd's firmware but when I rebooted the windows the installation was corrupted and I couldnt even repair it.

So I reinstalled windows, drivers etc and downloaded the latest magician, optimized the drive but I noticed that it states that AHCI mode is disabled and is also unable to detect SATA interface details.

Do I need to update bios or something? Maybe install it on the secondary sata slot?

Also it seems to me that that speeds arent that great although I havent run any tests yet.

Any ideas?

 

Sounds like a firmware issue to me - whether it's at your BIOS or the drive firmware. Are you sure the SSD firmware updated successfully? And does this occur in IDE mode as well?

 

Well samsung magician says I have the latest firmware installed. Are there even BIOS updates for my laptop? I can't even find out what motherboard is in there. What would occur in IDE? I don't get it.


Ok update:

I was wrong. IDE is selected in bios currently and not AHCI. Tried changing to either AHCI or RAID and windows won't boot. Keeps blabbering about choosing a boot device bla bla goes on windows loading screen---> blue screen--->restart. Can't repair or anything.

 

Windows loaded IDE drivers since it was in IDE mode when you installed. You will have to reinstall Windows while the BIOS setting for the drive is set to AHCI mode, so it loads the appropriate configuration at setup.

 

There is a way to change from IDE to AHCI without reinstalling Windows. Just follow the steps:

start with step 1 while you are still in Windows in IDE mode.

1) Run the Registry Editor (regedit.exe)
2) Navigate to Registry Key: HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Msahci
3) Set the "Start" value to 0 (zero)
4) Shut down
5) Start up again, but before Windows boots go into the BIOS and change the disk mode to "AHCI". Save the new BIOS configuration and restart so that Windows boots.

 

Kudos to both of you! It worked!! Speeds are doubled now according to magician! Thank u both

 

Unfortunetely my happiness didnt last long. Bios reverted to IDE mode and even changed the boot order without me doing anything?

 

Unless your CMOS battery is worn out and not saving the configurations anymore, that shouldn't happen. Did you reinstall Windows under AHCI or did you use Marecki's tutorial to edit the registry?

 

it sounds to me your CMOS battery is dead, however for BIOS update on the 1761:
MSI G-Series Unlocked BIOS

don't know if GT780/783 BIOS works but I'll dig in to it

 

Am sorry for the late answer. I used Marecki's tutorial to edit the registry to fix it. After a few restarts AHCI mode worked again. Now after 5 days the exact same thing happened. Boot order has changed again and it wont boot in AHCI mode again making my ssd useless in IDE. Am starting to get really frustrated here. Do I replace the CMOS battery? Can I find one on ebay? Any other ideas? Would really appreciate some help.

 

Hmm nice find man. But does this actually fix anything or is it just for unlocking stuff for overclocking?

 

yes you can find a new CMOS battery, when the cmos battery nearly dies the BIOS options gets reset to how it was when you last flashed it, thus for the unlocked BIOS, if the original options in the BIOS are set to AHCI, it will hold the option no matter you disconnect the battery or not, however if the CMOS battery completely dies your power button will shutdown preventing you from booting the machine at all, I recommend you going on ebay for a replacement, or call the customer service center of MSI for a proper replacement battery
