Clearing up a myth I heard about 4TB HDDs?

post #1 of 13
Thread Starter 
I was talking about my current mod project with a friend, and I mentioned I wanted to step up to a 4TB hard drive(sata III +SSD Caching, Core i7 3rd gen+HM77 Chipset), up from the 750GB HDD that I have now.
But he mentioned something about 4TB HDDs couldn't be a certain format for consumer grade hardware.

I'm looking at various 4TB hard drives and wondering if I should step down to a 3TB HDD, but I wanted to ask if there's anything special about drives above 3TB that it needs to be a certain format or connectivity?

As far as i know only thing you should be aware of is that 3tb+ drives should be formated as GPT drive maybe he was talking about that?

Drives over 2.2TB need to be partitioned/formatted in GPT instead of MBR unless you want multiple partitions under 2.2TB.

I have no idea what this means. Would you mind filling me in? I own a 3 TB external HDD but it's partitioned into a 700gb and 2gb partition(2 dedicated backups for 2 different drives).
I have no idea what GPT or MBR is.

The usage senario for the drive is a non boot mass storage drive, that will be paired with a 60GB SSD for Intel SSD Caching. All of the user's files(My documents/Pictures ect) are stored on the mass storage drive and not the boot drive, does this matter at all?

Basically MBR supports upto 2.2TB partitions, anything over that and you need GPT.

For example you 3TB will most likely be 2 MBR partitions, if you wanted to only have 1 2.7TB partition you would need to use GPT. when you first create the partition.

If it's non-boot, and you aren't using windows XP, GPT doesn't cause any trouble.

Otherwise, it can be difficult to install windows on to. The "normal" MBR method only lets you have a partition a little over 2TB, so you'd have to make two partitions.

Thanks guys, I was reading some of that stuff, I guess I should've been more wise with my word choice, and said "is there anything special I need to do to get the drive to format to the GPT? Or is it the same ordeal as my other drives"
I definitely want the full 4TB as a single partition.

Note: Win 7

You can do it in few clicks from Control Panel -> Adm. Tools -> Comp Management -> Disk Management , nothing hard/special in any way.

When you first put the drive in and go to disk management to partition it, GPT should be an option.
