Hard drive partitions
Posted on 2012-09-20
OK, I suddenly found out how stupid I am. I know that SSDs and HDDs that are fortmatted with an OS have an MBR at the beggining which is usually 100MBs or so.
But, I purchased a 3 TB drive (don't ask why) to use for a backup for my Storage Server. When I put the eSATA drive into its cradle, I thought it would just be unallocated. For some reason, it had an MBR on it and the rest was unallocated. I wanted to just have one formatted 3 TB drive.
Since it was external, it seemed difficult to do this. Next thing I know I have a 750GB drives with the MBR.
I moved it to another comptuer and connected it externally with one of those external drive kits. Same problem even with an Acronis Disk Director. Try as I might, I couldn't format it as one drive.
I then open the computer case and attached it using the Sata cable and the Sata power connector. I could then see the entire drive with the MBR. Finally, with the disk director, I could get the entire drive as one unitiated drive.
So to iniate it to, I guess, format it, it wants me to choose an MBR again. It also asks me to choose from GPT or MBR, which I know is Master Boot Record.
So my questions are:
Which should I choose?
If it is for storage only, does it even matter?
Do I have to even have the MBR or GPT for storage? I understand why I need it for booting the OS.
Why could I only see 750 MBs when it was an external eSATA. I had done several things to it with the partition software.
Very confused. I guess I need a tutorial on drives and how to format them.
