Hi All,

I would really appreciate some expert advise on this issue I have. I am running Windows 8.1 Professional, my PC is about 2 and a half years old and the motherboard is an 'Asus P8B75-M LX'.

I have just bought myself a new Seagate 5TB internal drive, model is a ST5000DM000. I managed to put the drive as an external and formatted the drive with disk management and also converted the disk to a GPT so it is just one partition as 5TB, the drive will work perfectly fine as an external in a case and I really do not want to split the partitions.

But, if I plug the drive as an internal via SATA cable as a second disk, my bios identifies the drive. Afterwards when Windows tries to boot it takes an additional 3-4 minutes to boot, eventually I log on and the disk is not present nor is it shown in disk management or even device manager.

I have tried using different SATA ports on my board (nearly all of them including one that is coloured different which I thought would be my savior), I am yet to try run it as a secondary drive in another machine which I hope to do in the coming week to see if I can replicate the issue.

Any feedback for this would be sincerely appreciated.

Many thanks

P.S I have also run Windows updates and tried installing chipset driver for my board from the Asus website

Try clearing your CMOS for your board. Look in the motherboard manual for specific instructions.

If it still doesn't work, check to make sure in BIOS the status of the hot plug / AHCI mode.

@Paul NZ. I have just updated my bios to 1403 as you recommended and seen no difference to the scenario, I have checked on the Seagate website and there are no firmware updates available for my new drive.

@tambeshakunt. I will look for my motherboard manual on how to clear my CMOS as never done that before, I did notice the bios has been set to IDE not AHCI and if I set the bios to AHCI I can no longer boot into Windows as it fails on the loading screen. I have seen this problem before in the past and always remembered to solve it it would be a matter of changing this setting. Is there a way for me to boot into Windows with this setting as AHCI or do I need to reload Windows with the setting on?

Many thanks for your responses

Yes you need to reinstall Windows if you change to AHCI (thats why I said check the status).

Hi tambeshakunt,

I was given these instructions from another forum, I am yet to try it as will do so this evening when I get home.

Do this before you switch to AHCI :
Change IDE to AHCI
1. Startup "Regedit
2. Open HKEY_LOCAL_MACHINE / SYSTEM / CurrentControlset / Services
3. Open msahci
4. In the right field left click on "start" and go to Modify
5. In the value Data field enter "0" and click "ok"
6. exit "Regedit"
7. Reboot Rig and enter BIOS (hold "Delete" key while Booting

Now change In your BIOS select SATA Mode to AHCI from IDE.

Hopefully this does fix and I will not need to reinstall Windows?

Kind regards

Alex

Yes that will fix it (most likely) but I always like to, and recommend reinstalling for best results.

Hi again,

So this is the current state, I have managed to work around get my bios to AHCI without reloading Windows. Now, I get the never ending spinning wheel on start up, if I enable hot swap on a SATA port and plug the drive in, the disk does come up in Device manager. However, it does not come up in This PC or in Disk management. Starting to think this is a lost cause and I will need to upgrade my board or even reload Windows maybe?

Many thanks as always

Important point I don't see above: To use any HDD over 2 TB, you MUST be using a 64-bit version of Windows. Microsoft only supplies drivers for GPT-Partitioned large HDD units with its 64-bit versions. Their 32-bit versions do NOT have the driver required and cannot access such devices.

Hi Paperboy,

Thanks for the post. Unfortunately no I am running 64 bit version of Windows 8.1, I know I should have mentioned that in my previous post. Any other ideas?
