Windows 10: Installing win10 I lost my 1TB drive

When I installed Win 10 I found my 2nd (1TB) drive is missing. Device manager lists two hard drives...

:)

 

Portable HD 1TB not reconized since Win10 Fall update

1TB SP Armor portable HD not recognized on 3.0 or 2.0 USB ports since Win10 Fall update. Ports will read USB flash drives. Also 1TB drive will read on another PC running Win 10 on both 3.0 & 2.0 ports. I have deleted drivers and reinstalled. Any suggestions
will be helpful. Thanks, Tom

 

Lost the Seagate...

The drive seems to be completely dead, my computer will not boot if I have it connected...to the windows cd or the new installation on the F1 drive (which is the boot drive now by the way)

Thanks for the above article, im booting into Vista: U 64 right now, I cant follow those steps if the drive is in, it will lock up before it gets that far or if its not a cold boot the drive does not appear on the list.

 

1TB hard drive changed to 31.6GBs' after Windows was installed on it.

Hello,

Recently I installed windows 10 onto my 1TB seagate hard drive which as I later found out was a bad idea as it had deleted all of its content for ever. I have asked Microsoft Help and they suggested all these idea's which didn't work. I understand that I
need to format my hard drive again to change its size back to its original 1TB, however when I try and format it it simply gives me a horde of errors "unable to format" I have tried several methods and I am coming up with nothing.

I don't want to buy a new hard drive if this on is fixable, I'm sure anyone could understand that.

Things to not about resolving.

• I know there is no problem with the hard drive itself because I was using it non stop before I tried installing windows onto it.
• I have tried several third party programs and non of them have seemed to do anything.

Thanks again and I hope this can be resolved.
