Oops, posted without completing.
I have got an external USB2 hard drive.
According to Windows 8's "Computer Management" utility, this has got 3 primary partitions and 5 logical ones within an "extended" partition.
This is the problem though.
I have also got circa 100GB of unallocated space left that I'd like to format and use.
Upon trying to make a "simple" volume in Windows 8, I get the message:-
"You cannot create a new volume in this unallocated space because the disk already contains the maximum number of partitions."
How can I resolve this please?
I am copying the data from 1 of the primary partitions into a new folder on my computer as I type this.
After this completes, can I convert this primary partition to a logical one or not? Will this work so that I can format the unallocated space as another logical drive inside an extended partition?
If not, can I delete this primary partition and merge this with the unallocated space to make a new large blank one instead?
All answers and advice gratefully appreciated.
