Formatting an External Drive (4TB Seagate)

[m654321]

For simplicity I always use MSDOS partition table type, It's worked for me.
I think the GPT is only useful if you want more than 4 partitions per disk..?? ((IIRC))

Edit,
Unless you use extended partition under MSDOS

@Wirezfree:
I'm using the external portable drive as a single large partition simply for backup data storage.

The PC has two internal physical drives, one for the operating systems (drive1) & the other for data storage (drive2).  Both drives have an MSDOS partition table. I am using an extended partition (i.e. it contains logical partitions within it) so I can install more than 4 operating systems on drive1 (if need be at a later date).

I mention this in light of your closing comment re. 'Edit'.  So from what I've just said, does this mean I can still use MSDOS on the external drive - I assume it will be formatted as a logical rather than a primary partition?

Thanks Dave for your patience - I just want to get it right...
