Windows 8.1 fails to optimize System Reserved partition


I have Windows 8.1 Professional x64 running from a 256GB OCZ Vertex 4 SSD.

Windows has divided the drive in to two partitions:

  1. System Reserved (350MB NTFS)
  2. C: (238.13GB NTFS)

Whenever Windows attempts to optimize the System Reserved partition, I get an error in the event log:

Log Name:      Application
Source:        Microsoft-Windows-Defrag
Date:          1/29/2014 11:07:54 AM
Event ID:      257
Task Category: None
Level:         Error
Keywords:      Classic
User:          N/A
Computer:      My_Computer
The volume System Reserved was not optimized because an error was encountered: The parameter is incorrect. (0x80070057)
Event Xml:
<Event xmlns="">
    <Provider Name="Microsoft-Windows-Defrag" />
    <EventID Qualifiers="32768">257</EventID>
    <TimeCreated SystemTime="2014-01-29T17:07:54.000000000Z" />
    <Security />
    <Data>System Reserved</Data>
    <Data>The parameter is incorrect. (0x80070057)</Data>

Should I just remove this from the list of items that are on the optimize schedule or is there a way to fix this issue such that the optimization can succeed?

Not only on SSD but also on Hard Drive the problem exists: System Reserved Needs Optimization
