I have a removable hard drive I just bought to add to my windows 7 box.

Its one of those that I can slide in and slide out hard drive docks.

I was just wondering when I first put in it with a bran new fresh out of the package hard drive why it made that disk a (primary Partation)

How can I change from Primary Partition to Logical Drive and vise versa.

Here is my layout

DISK 0 - 150 GIG       -   C: (System, Boot, Page file, Active,    E: HP recovery (Primary Partation)      F: Where I store stuff
DISK 1 - 2 T               - (Primary Partition) This is the removable  slide in slide out drive that I have its a vantec with a fan and I can lock it with a key
DISK 2 - 2 T               - (Logical Drive) This drive is outside the box connected via SATA cable and its a dock. The hard drive is sorta exposed and I could remove and place drives in there  Its a Nextstar HD Dock)

as far as I know, that is not possible, you have to copy your data, delete and recreate the partitions the way you want...

Sorry

You need to use third party software.
If you want to use only windows you need to delete the partition and create o new one with the type that you want.

A hard disk can only hold 4 primary partitions on its Master Boot Record (MBR). Once the fourth primary is created, windows creates an extended partition into which Logical Partitions can be created.

This was done so that more than 4 can be created on a disk however they would not be bootable (Cannot be OS partitions).

The question is really, what are you trying to achieve here? Is it that you want to move partitions to different drives? If so as compaqus said use any partitioning tool you trust (I use BootitNG as it is a bootable CD image which means you know the partition could not be accessed while you are cloning, moving, copying etc.)

If it stays primary partition DISK1 (reference previous post for my layout) would it work just the same as any logic partition. Is the only difference means that it can be booted to

I did have at one point with my dock drive that is Drive 2 an issue where it I think lost something due to power lost and I had to use a data recovery tool to gain everything back. That's why I want to play it safe. Sence there is no data on that drive I want to make sure i start off right

OK I understand that but this entire disk is Primary. Unlike the other 2t drive i have in the dock which its entire disk is Logic.

I should not have to create another partation on this disk for it to be logic just make the entire think primary or vise versa

Also is it better to have it be primary ? for removable purposes

In your situation, it doesn't matter if it's logical or primary so I wouldn't worry about it.  (Or is there another reason you think it matters?  Why do you want to change it?)

CWCertus1 was mostly correct.  On any disk, because of history, there is only space for four (4) primary partitions in the primary partition table.  If you want more than four partitions, you can have three primary partitions, the fourth primary partition is really a container (the extended partition) to house all the other logical partitions within it.

Windows only recognizes one primary partition per disk.  Other OSs (e.g. Linux) can use various primary partitions per disk.  Probably because of this, Windows only wants to create logical partitions on the disk.

You can use this to your advantage if you want to multi-boot various Windows versions by having each one in it's own primary partition with the shared data on a logical partition.  Each Window version won't see any other of the system disks of the other Windows versions as it can only use one primary partition per disk.

Getting back to your original question, though.  As I said, if you don't see any problems, I'd just leave it alone.  If you want to change it, then you can use 3rd party tools or backup your data and create the partitions as you like (if Windows doesn't do it, you can get a live Linux CD and use GParted, though be careful which partitions you are deleting and creating and on which disk you do it on or you might delete your main system.)

Just save your data, install aeseus (link in second post) and delete/create whatever you need.

As other people said it doesn't really matter if it is logical or primary but if you really want them like this, there you go.

There is no difference for you if the drive has primary or extended with logical drives inside partitioning scheme. Windows will handle all the things itself. But if this bothers you then copy all data from F: to that 2TB drive and then delete F: drive. After that delete Extended partition. Now you have free space.
Right click on free space and select Create Partition. Select type as Primary. Format it as NTFS. Assign F: drive. Now you can copy data back.
Also if you want to have that big drive primary then convert it using Paragon Partition Manager 11 Personal www.paragon-software.com
But actually I don't think you need to convert it. Only if you want to play a bit with the drive partitioning tools.
