Windows 7: Win 7 System Reserved partition smaller than 100MB?

Win 7 System Reserved partition smaller than 100MB?

I'm in the process of swapping out an HDD boot drive for a new Crucial M4 SSD, and discovered that a 100MB partition I created for "system reserved" files got squeezed down to 79MB by the Acronis cloning software I used. The SSD booted just fine with the smaller partition, and my offset is set to the recommended 1024. Is there any reason I need to be worried about a system reserved partition that isn't exactly 100MB?

Short version, no.

Does no harm to the system, but please post a screenshot of you partition manager open.

Here is an earlier thread about the same case, if your partition is unassigned as well than you can 'remove' it or just leave it alone.

Here's a partition manager screenshot, along with an AS-SSD benchmark. No unallocated space on Disk 0, and the SSD seems to be working just fine.

Can't believe I'm using my 150GB Raptor as a storage drive now.

No reason to worry. There is plenty of free space on the little system partition. It may only get tight when you make a double boot.

I am amazed that the Acronis tool even allocated the little system partition. The Paragon migration tool eliminates it and moves the bootmgr to C:

The M4 looks good. Just today I installed an M4 on my new system. But I have not yet wired it up (maybe tomorrow). Once running, I will compare with your nums. The 4K nums seem to be a bit low. The Vertex2 on my laptop is faster. But those are only nums anyhow.
