Windows 10: Is there any way to get Win10 to see a hard drive from Win7?

I have a 3TB hard disk that was my archive drive for all the video and audio media files on my Media-Centre PC which is a Win7 OS

When I installed it as an internal drive on my current machine it is connected in the BIOS but Win10 OS it does not show in File Explorer, Disk Management or Device Manager?

On my Win10 OS I confirmed that auto-mount is enabled, and to double check I installed it back into the Win7 OS, and it is OK. Also double checked via a USB dock with no problems

Stumped now so I am wondering if anyone out there may know any way to get Win10 to see a Win7 drive?

Any suggestions most appreciated


Best wishes for 2021 to all. Regards TW

Win10 on new hard drive, how to activate

• Installed Win10 to new hard drive, but Win7 code does not work.
• Tried online (slui.exe 4) activation:
  • entered numeric codes online - which failed,
  • talked to 1st line tech who entered Win7 code - did not work,
  • transferred me to 2nd line tech and no one came on the phone line after 2.5 hours.

Win7 was pre-installed on HP computer with no media provided and HP support has no process to supply replacement media or ISO (last HP purchase). Tried to install Win7 to new drive using Recovery Disks I created, but it could not find system image.

Not willing to return to old hard drive as the new one has SSD and is at least 3 (7?) times faster.

QUESTION 1: Is my only option now to buy either Win7 or Win10?

QUESTION 2: Without activation, when will Win10 no longer boot? If 12 months, I can retry online activation later.

 

Hard drives cannot be accessed after switch from Win7 to Win10

Hello. I am a victim of an apparently rare bug.

I wanted to try out Win10 as a partition for a dual boot option (Since some games run better on Win10 than Win7).

I heard rumors of Win10 being incredibly agressive but I had no idea how much. Win10 tried to eat and destroy my Win7 partition by messing with, I'm not sure, system files ? Apparently everyone on the web are saying that it's impossible to have a dual boot
of Win7 and Win10 because Win10.

Then I realized that out of 2 SSDs and 3 hard drive, 1SSD and 2 hard drive could not be accessed anymore. No matter what. I tried to boot with win10, I tried to boot with Win7, it didn't work.

I bought an USB > SATA adapter to try and see if it would work that way, it doesn't.

This is what Disk Management shows me for one of my hard drive when linked through the USB > SATA adapter.





At first I thought it could have been a virus, one of those locking trojan that makes you pay to unlock your hard drive, but it really doesn't look like it. No prompt, no infection, Malware Bytes, Rogue Killer, Avast... No information whatsoever.

What is going on ?

I have several friends that have had troubles with Win10 and had to go back to Win7 because of a lot of problem with programs, drivers for hardware, but I never heard of problems for hard drives.

I have now deleted the Win10 partition but am left with 3 crippled drives.

Can someone please help me ?

Thank you.

 

Sharing drives with Win7 & Win10

I uncheck the Fast Startup. Then I shutdown the system & connect an empty hard disk & start up again. Then I format the disk & transferred a few Gb of data to the new hard disk & shut down. After that I swap over to Win7 & startup. Now I can access everything
in the hard disk. Then I transferred 50Gb of pictures & videos to this disk & shutdown. I switch over to Win10 & I could only see the previous data created in Win10 but not the 50Gb of pictures & video from Win7. Back to square one.

In Win7 the new hard disk register at 20% usage but in Win10 it's only 2%

There's something different between Win10 & the rest of the older OS

Then I did a restart & this time there's a boot scanning of the new hard disk. After that I can access all the new data from Win7 & can play all the videos too. I shutdown & switch to Win7 & there's a boot scanning again. Now able to access everything. Why
do the hard disk need to scan at bootup in order to be accessed?

If I share my 2pcs of 2TB hard disks with Win10 a lot of time will be spent on boot scanning. Is there any way to go around this? Until then Win7 is still my primary working system
