Was just my effort to accentuate they were separate entities while still part of the same partition, verified by both being changed into a single unallocated space when the larger was deleted.

"SSD General" & "SSD Trade" are both boot volumes with each containing a unique Win7 operating system. Maybe incorrectly I call them "bootable partitions". "SSD System Reserved" contains the system volume.

I did download the Partition Wizard and to my surprise it displayed 3 1Mb unallocated entities. The one you still see in the attached snip, one at the other end and another between "SSD System reserved" and "SSD General". Using the Wizard I simply deleted the "SSD Common" and absorbed the resulting free space into the existing partitions. The 1Mb free space that still remains seems to be untouchable due to its location, not going to fret over that one.

Out of curiosity I decided to run the Intel utility again after making these changes to see if it would recreated those 1Mb free spaces, as can be seen none were created. So the method of creation remains a mystery. I also found that Outlook can share a PST file even though it is located on the boot volume of one of the installed OS's and in the app-created user folder. Due to this I decided there was no need to recreate the "SSD Common" partition.

In a nutshell, I'm Done!

Thanks much for your interest and help. Will also keep that MiniTool Partition Wizard handy as it looks to be a very versatile tool, appreciate the heads-up on that one.

sometimes it's normal to have such free spaces around. It's due to complicated technical reasons, basically the partitions have to be aligned with the hardware sectors or something like that, if it isn't performance degrades as non-aligned partitions will require more read/write cycles to get the same data.

If after you try as suggested it still doesn't disappear, it's probably like I said and the program generating the partitions is smart enough to align the partitions correctly, "wasting" a few MB none will feel the loss of anyway.

Since you did manage to erase some of them, check that the partition alignment is still correct. I rarely use tools for SSDs, others can suggest what to use.
