MBR is fine as long as you aren't running anything really old like Windows 95 or 2000. Even XP will pick it up.
I'm a little worried/concerned giving advice much more than that. The screen that you posted to initialize your drive is coming from within a Windows OS. If you initialize the new 3.0TB drive from inside windows it'll be fine - it will ask you to format the drive so it will lose all data.
What I don't fully understand is why you would be installing an OS on the 3.0TB drive AND have one on the 2.0TB drive already in the machine. If you do that and don't have proper backups and do a proper install you can risk losing everything on the 2.0TB drive.
I would just be careful and have EVERYTHING backed up.
Hi WinstonTJ,
I have decided not to install any OS on new 3 TB HDD.
The other 2 TB HDD is just the back up data drive & does not have OS on it either.
I have a separate 500 GB HDD for Windows-7 ( 64 bit ) that I have been using all the time.
I bought this 3 TB HDD because one other 2 TB back up HDD crashed & I needed a back up of the current 2 TB HDD & also needed more space.
So now I need help installing the new 3 TB HDD & be able to use full 3 TB HDD Space. I have not initialized this 3 TB HDD because it is detected as only 2 TB HDD. So if I initialize it as an MBR I probably will end up with only 2 TB of space.
I was encouraged from your extensive experience with T-7500 workstations & you were able to install not only 3 TB but even 4 & 5 TB HDD on this machine. Yes, I have a brand new Dell T-7500 machine.
So please tell me how can I get the full 3 TB space on this HDD drive ?
Right now it is still a totally fresh HDD, detected as 2 TB HDD & asking me to initialize it either as MBR or GPT but I haven't done it because I am afraid I might end up with only 2 TB HDD. ( I am using Windows-7 (64 bit) on a 500 GB HDD & connecting this as a slave 3 TB HDD.
Thank You again WinstonTJ. I appreciate your help.
