I have two WD hard drives with the OS installed on one and the other is for storage. The second one stopped showing up in BIOS and does not allow me to boot into Windows at all.

Now only if I unplug the second drive I can boot with the primary drive into Windows without any problems. Both hard drives were using AHCI mode before but switching to IDE the second drive shows up in BIOS. Unfortunately using IDE I can't boot into Windows anymore with the primary drive and I get a BSOD with an inaccessible device error.

So as of now I've disconnected the second drive and have the primary drive with the OS installed running in AHCI. Is there anything I can do to get the second drive to work? I have tried plugging the second drive into different SATA ports but to no avail. Any help would be appreciated.

Specs :
OS - Windows 10 64-bit
Motherboard - Asus P8H61-M LX3 R2.0
RAM - 2x Transcend 8GB DDR3 1600Mhz
Primary drive with OS - WD Blue 1TB WD10EZEX
Secondary drive - WD Green 1TB WD10EARS

Hi there BlackIce21,

That is really unpleasant. :(

I believe that except for using different SATA ports, you can use different SATA and power cables as well.

What happens when your system is not booting? Do you get some sort of an error message?

In case the issue persists, I believe you will need to attach the drive as an external, once the system is running. You will need a SATA to USB adapter + power cord, as this is a 3.5'' drive.

If the drive is accessible, then you can back up the data stored on it and run both short and extended DLG tests: http://products.wdc.com/support/kb.ashx?id=7GQ2a2

Let me know how this goes,

Hi thank you for replying. Yes I've also tried using different SATA and power cables. The error I received was an inaccessible boot device BSOD after the Windows logo and the spinning circles.

Actually now I tried plugging in the second drive once again without changing anything at all and it is on the scanning and repairing drive screen. It's been at 2% close to 40 minutes on one partition, is this normal? The first out of the three partitions had completed very quickly. I've also ordered a SATA to USB adapter, hopefully the scanning and repairing process fixes it and I won't be needing it. Either way I'll also run the tool you provided, thanks again.

The disk check process could indicate that there's something wrong with the drive as well.
It may take a long time. Just leave it for a while. If it takes really long time, you will need to stop it at one point.

Make sure the adapter is for a 3.5'' drive.

Cheers,

The check disk process completed and I am now able to access two of the three partitions on the drive. The third and the largest partition when accessed says the disk structure is corrupted and unreadable. I've checked in the Windows disk management and it shows that particular partition as RAW format. Is there a way to recover the files from there?

Running a quick test with the Data Lifeguard tool shows me this for the drive.

I tried backing up the data on the accessible partitions but it keeps freezing and just sits like that for hours. I rebooted after that and now things are much worse. I can't even see the accessible partitions anymore in the file explorer. But I checked in Disk Management and it now says Disk 1 is unknown and uninitialized. A windows pops up asking if I want to initialize with MBR or GPT partition styles.

I've also used HDD Regenerator to try and see if it does anything but it says the MBR is corrupted during the prescan. In addition to this, I also used HD Sentinel and it says there are bad sectors and data must be backed up immediately. Does this mean the drive is completely dead? I have over 700GB of invaluable data on this, so is there anything else I can do to at least gain access to it and recover as much as I can?

The drive likely is starting to physically fail and now will have a damaged file system as a result of running chkdsk. If you value your data, you should seriously consider contacting a professional data recovery lab before any further damage is done to your drive.

If you want to go the DIY route, your next step should be to try an get a full sector-by-sector clone of the drive with a program or hardware imager that can work around bad sectors and handle unstable hard drives.
