Yes, if it contains nothing you need then that would be a good idea.

An even better idea would be to WIPE that drive. I believe GParted has that functionality. This is where you write all zeros to the entire drive. Do it overnight, as it takes about 6 hours on a 1TB drive.

Then I suggest running the hard disk manufacturer's diagnostic software on the drive.
The fact that it would not format the last partition could be due to a bad file table (and that would be fixed in the wipe), or it could be the drive is headed south. The test will give a clue to which it is.

If the SSD is formatted GPT then you are free to format the spinner GPT.
If the SSD is formatted MBR then the spinner must be MBR.
The reason is that W7 must be installed on the disk that is formatted GPT in a UEFI system with mixed format hard drives.
Does this mean that IF there is only 1 GPT disk in the system then it must be the OS disk?
This means that if there is more than one hard drive installed in a PC, and any one of those hard drives is formatted GPT, then then Windows should be on that drive.

I do not know what would happen if you did introduce a GPT drive in a system that had Windows already on another MBR drive, as I have always just followed the rules. But I assume there would be an issue with start up.

To see what the drive format is, see here:

You can use GPT for storage on an MBR system. For most UEFI systems (they're all different) you need Legacy or CSM to combine MBR and GPT.

Hey Greg. Thanks for that video. Haven't seen that one! I'll check it out later today.

The information I got comes from here:
Windows and GPT FAQ

The key is that the boot partition must reside on a GPT disk. So technically you are right, since the OS and boot partition can be separated and can even be on different hard drives. But since that is more of an advanced system setup, I try not to get into it with posters that are just trying to get a basic setup to work on one of these new UEFI systems. I try and keep it simple.

I ran chkdsk all night. It came up w/errors and told me to go look for a folder called 'errors'??? But I didn't see anything. I wasn't ignoring advice, I had already started checking it and was not messing w/PCs last night.

Disk 0 (SSD) MBR
Disk 1 GPT
Disk 2 MBR (this is the one that had the errors). It still won't let me format the partition.

SO! I guess you would call this an MBR system w/a GPT storage and a MBR storage drive.

Disk 2 should be nuked and reformatted per Greg's suggestion.

If y'all suggest, I can reformat Disk 1 but first I'll need to move its data to Disk 2.

Suggestions?

Well, as Gregrocker has pointed out, you could just set the UEFI/BIOS to CSM and be done with it.
CSM sets the system to boot in Legacy BIOS Mode and ignores the GPT partition protocol.
Personally I would want my system running the advanced features I paid for, so I would start over and do the chores necessary to format the SSD GPT. But that's me.

And yes, nuke that puppy.
Lots of us here use DISKPART to do that chore because it seems to work best.
But a disk wipe is a disk wipe, and any program that does one will do just fine.

You are hoping that it is only a case of unrecoverable file system errors that is failing in Dskchk and not bad sectors. After the wipe, create a new single partition and run dskchk again. If it shows errors after the wipe you are probably looking at a failing hard drive.
You can run Seagate Seatools to double check this.

I'm curious if the boot partition is on Disk 1 and the system starts up and runs fine like that.
If you have time, could you post a screen shot of Disk Management with Disk 0 and Disk 1 attached?

I have Seatools running. I'm running 1 of the 1st tests.

The last screen shot (page 4) is the current config.
But... it's booting from the SSD. Disk 1 never had the boot partition as far as I know. Disk 2 is the one that had the OS and 100mb partition which has now been deleted and reformatted.

Sorry, I don't know how to link to a specific post.

No problem - I see it.
Actually I just remembered that the GPT boot partition is hidden in Disk Management anyway. You might be able to see it in GParted. It will be formatted FAT16 or FAT32 and will be 100MB.

If your system BIOS is not already set to boot to Legacy BIOS (by default we assume) then I may be wrong about the GPT/MBR Windows 7 startup issue. I realize you've got a lot going on there, but I would love to know if it matters at all in the real world, so if you got the chance to check the BIOS settings for that......

I don't have any start up issues ;-)

Right now my only issue is the partition on Disk 2 that is unallocated and wants to stay that way.
I'm doing a long generic seatools tests and running out w/my daughter for several hours.
I ran 2 short tests and there were no issues.

Only reason I'm running this one and not doing what y'all suggested is because I'm running out and will be afk for a while.

If it's an MBR system drive and therefore set to CSM in a UEFI BIOS, it should take a GPT storage drive without problems caused by that. But the partition problem is on an MBR disk so that's not involved as far as I can tell anyway.

What is the exact error you're getting when you try to create a partition there? Partition or Volume - Create New
