Windows 7: New HDD Showing UnAllocated Space

4 Weeks Ago   #1

New HDD Showing UnAllocated Space

I have just installed another SATA-connected WD 2TB HDD

Before connecting it to SATA, I connected it via a USB enclosure for formatting and allocation.

For what it's worth, I never could get it to show in Windows native Disk Management, yet it showed right up in Free EaseUS Partition Master; once I got it set up, then it showed up in Windows DM.
I had the same experience a few days ago with another HDD.
Had I not have had EaseUS to fall back on, I may have thought I had a DOA HDD.

Now that I have it internally connected and up and running, in Disk Management it shows 8MB unallocated on the left side and 1MB unallocated on the right side.

I might have expected a few stray MBs all connected on the same side.

I know it is only a total 9MB, but this annoys me; I won't be able to sleep tonight.

I right-clicked to see if I could expand the volume, but Expand Volume was greyed out.

Neither of the other two show any unallocated space at all.

Can I fix this or is it normal and necessary ?

Maybe wipe it and reenlist to see if it goes away ?

On EDIT:>>> Update:>>> I have added another identical HDD, everything formatted and connected in the same manner, and this HDD is also displaying the two mysterious unallocated areas; 8MB on the extreme left end and 1MB on the extreme right end.
Maybe it is normal.
Your thoughts and input please.

Thanks for reading and all help is appreciated.

It's hard to say without seeing it but I wonder if it's just showing boot sector and partition table as unallocated space

Thanks; that may very well be the explanation for the mystery space.

It is sort of scary that it says that merging that unallocated space into the partition may result in the data becoming inaccessible, but I have several disks that do not exhibit the space.

Maybe I shouldn't as my wife says "obsess" about such things.
