Specs: Windows 7 Ultimate SP1 x64, Intel C2D 3.33GHz / 8GB RAM
I have a Dell Optiplex 780 MT(MiniTower) setup with 2 Seagate Barracuda 7200.10 750GB HDD setup as RAID-0 using the Dell Built-in RAID Manager w/Windows 10 - and Secondary HDD 3TB Seagate Desktop HDD. I Decided to downgrade to Windows 7 from Windows 10 - I Booted to USB Win7 Installer and installed windows 7 ultimate x64 no problem, but for some reason my secondary 3TB HDD is prompting Chkdsk and Windows 7 can't read it; "D:\ is not accessible. The file or directory is corrupted and unreadable." It was fine before I wiped and installed 7, there is no encryption or anything like that added to the drive. Any suggestions?

✔ Best Answer
When reinstalling an operating system on an existing system you should always unplug all other drives. This is first to be sure that you install to the correct drive only. And second because sometimes Windows installer will install the boot sector or reserve partition on a different drive than you are already beginning to install Windows on. By unplugging all other drives you force the installer to choose the correct drive. This has been a known 'glitch' through quite a number of versions of Windows installers.
If you now unplug the drive and Windows fails to boot then you will be sure that this is what corrupted the drive.
Please follow the above recommendations on recovering the drive.
If Windows does not boot when the drive is unplugged or after recovery then I would recommend reinstalling or doing a Repair Install (fixing the boot components) with the other drive unplugged.

You have to be a little bit crazy to keep you from going insane.
