SSD storage working in one build (Win7), but not in other build (Win10). Can't access in ANY way, but shows in BIOS.

[illumind]

I have a 500GB SSD storage drive, but when I upgraded to Windows 10 (from 7) it now doesn't show up in Explorer, and only shows up as 'Free space' 'Healthy Recovery' in Disk Management next to my main 250GB SSD drive. I can't assign a drive letter or do anything with it. It just reads as 100% free space, but in my other Windows 7 build it still accesses all my files perfectly.

Reads as: (in Win10)
240GB: C:\ Simple | Basic | NTFS | Heathly | 83% free
500GB: (Disk 0 Partition 2) | Simple | Basic | Healthy | Recovery Partition | 100% Free

In the next pane down my boot SSD reads as "'Disk 0' (240GB) "C:\ NTFS etc". Then horizontally across is a separate box that reads "468MB" 'healthy recovery', which I assume is my storage drive?

It doesn't show up in CMD/Diskpart/File Explorer. The only option in Disk Management is 'help' when right clicked.

I can't see how the below solution worked, but this person said it was a RAM issue - surely not?

Any and all help is appreciated!

Just to confirm...no problem with your 240 GB or 250 GB boot drive (you indicate both capacities) in that that your system boots & functions without any problems other than your 500 GB secondary HDD is now devoid of your backup data.

There are 1,001 reasons for this problem. You can do a Google search and determine whether there's any viable program for recovering your lost data. Probably not, but you might want to try.

Assuming you haven't done so already (you should have)...run a HDD diagnostic program to test the health of the 500 GB HDD. You might be dealing with a defective drive. If the disk checks out healthy, presumably you can reuse it for storage as previously and simply conclude the "free space" problem was an anomaly. Obviously you would want to reinitialize, partition, & format the drive.

Thank you so much for taking the time to reply. I've recently reinstalled the drive in a Windows 7 machine and all my data is there and acessable! *Phew*. But I don't know how to get it working in my new Windows 10 build, it just comes up as 'help' when I right click on it in disk management. The 500GB storage drive does appear in BIOS, but not in CMD/Diskpart promt on my Windows 10 build. And, in Disk Manager it appears, but without any NTFS etc. Does not appear in Win 10 Crystal Disk, but is 100% Good in Win 7 build Crystal Disk.

I'll update my initial post to reflect the above.

Any ideas of how to proceed?

Thanks again!

1. If I correctly understand your current situation (and I'm not sure that I do!), you've been able to access the data on your 500 GB HDD on a different PC with the Win 7 OS. So if that's the case it appears there's no problem with that HDD and it should be detected and its data accessed in your new Win 10 build. Do I have this right, so far?

2. Presumably your new Win 10 build boots & functions without any problems with your SSD boot drive, right?

3. But you're having a problem with the 500 GB secondary HDD in that there's some problem with the drive being detected in that system, right? Right?

4. Is the drive listed in the "Disk drives" listing of Device Manager?

5. You've indicated the drive is apparently listed in Disk Management. DOES IT HAVE A DRIVE LETTER ASSIGNED TO IT? If not, assign a drive letter.

6. Ensure the drive is properly connected in the system. Change SATA data ports.

7. Download the HDD diagnostic program from the drive's manufacturer to test the health of the drive.
