secondary hard drive not full size after new OS install

[DamianTC]

I have an older system with 2 seagate sata hard drives. 1TB and 3TB. I kept the OS and program files installed on the 1TB, and I would only keep media files (video, audio, images) on the 3TB. I had to use Seagate’s Disc Wizard to be able to use the entire 3TB drive, as a 2TB and 1TB.

I recently upgraded the OS on the main drive from Win7-64 to Win10-32, which required a clean install. Once Win10 was installed, I could still see the secondary 3TB, but only as one 2TB drive (not the 2TB+1TB).

I downloaded and installed Seagate Disc Wizard again to get the full size back on the 3TB, but the only options I am seeing will require to format and delete everything to get it back to the full 3TB.

Is there a procedure I need to do to get the drive back the way it was with it’s data? I can still see all data on the 2TB section of the drive, but missing the remaining 1TB section along with the data I had on that.

I do have a backup of my other 1TB drive that the OS was installed on. This also has the old Seagate Disc Wizard program that created the 3TB. Is there a file I need from it’s folder to map the drives back?

does Control Panel, Admin Tools, Computer Management, Disk Management, see both partitions on the secondary drive?
and are they both formatted as NTFS?

Yes, sorry for the late reply. I actually found a backup of all data that was on the missing section of the drive. Therefore I used Disk Management to reformat to all one drive and replaced all data with the backup I had.

I actually preferred one drive for the whole space anyways. Thank you for your reply.

Praise Be for Backups.
glad you got it sorted.
