Another update to my instructions to reclaim SSD space on the Yoga 13
(128GB SSD, 4GB RAM). Added accurate details to make it easier to follow.
DISCLAIMER: By following these steps, you assume all risks for anything
and everything that goes wrong. Proceed with caution.
1) Create a Windows 8 Recovery Drive (external harddrive or 8GB USB stick).
Control Panel -> Search for "Recovery" -> "Create a recovery drive",
then check the box "Copy the recovery partition from the PC to
the recovery drive".
If anything goes wrong, use this Recovery Drive to re-install Windows 8.
2) Copy Lenovo D:\ to C:\Lenovo\.
Admin CMD> ROBOCOPY D:\Application C:\Lenovo\Application /MIR /NFL /NDL
Admin CMD> ROBOCOPY D:\drivers C:\Lenovo\drivers /MIR /NFL /NDL
3) Control Panel -> Programs -> Uninstall a programs
Uninstall "Intel Rapid Start Technology".
Reboot when prompted.
4) Computer -> Manage -> Storage -> Disk Management
Right click on D:\ -> Change Drive Letter and Paths -> Remove D:
Use DISKPART to delete 3 partitions:
Admin CMD> diskpart
DISKPART> sel disk 0
DISKPART> list part
Partition ### Type Size Offset
------------- ---------------- ------- -------
Partition 1 Recovery 1000 MB 1024 KB
Partition 2 System 260 MB 1001 MB
Partition 3 Unknown 1000 MB 1261 MB
Partition 4 Reserved 128 MB 2261 MB
Partition 5 Primary 63 GB 2389 MB
Partition 6 Primary 25 GB 66 GB
Partition 7 Unknown 8 GB 91 GB
Partition 8 Recovery 20 GB 99 GB
Delete the last 3 partitions.
DISKPART> sel part 8
DISKPART> del part override
DISKPART> sel part 7
DISKPART> del part override
DISKPART> sel part 6
DISKPART> del part override
Reboot.
5) Computer -> Manage -> Storage -> Disk Management
Right click on ( C: ) in the diagram -> Extend Volume...
Extend by 50175 MB, leaving 4GB at the end. (54271 - 4096 = 50175)
If you upgraded RAM to 8GB, subtract 8192 instead of 4096.
Right click on the unallocated space -> New Simple Volume...
Create a simple volume with the 4GB (4096 MB) unallocated space.
Don't assign a drive letter to it, don't format it.
Admin CMD> diskpart
DISKPART> sel disk 0
DISKPART> list part
Partition ### Type Size Offset
------------- ---------------- ------- -------
Partition 1 Recovery 1000 MB 1024 KB
Partition 2 System 260 MB 1001 MB
Partition 3 Unknown 1000 MB 1261 MB
Partition 4 Reserved 128 MB 2261 MB
Partition 5 Primary 112 GB 2389 MB
Partition 6 Primary 4096 MB 115 GB
Notice partition 6 is the one just created (4096 MB = 4GB).
DISKPART> sel part 6
DISKPART> set id=D3BFE2DE-3DAF-11DF-BA40-E3A556D89593
6) Download Intel Rapid Start from:
http://downloadcenter.intel.com/Detail_Desc.aspx?DwnldID=21612
Execute Rapid_Start_Win7_2.1.0.1002.exe to extract the driver
to the directory C:\Driver_Win7. If you change the default directory
to somewhere else, then you will get an error afterwards. Don't worry,
just execute IRST\setup.exe at your designated directory.
IRST\setup.exe should install IRST without any problem. Once
installed, find the IRST Manager in the Notification Icon and use it to
adjust IRST parameters to your liking.
You could test IRST by enabling its timer and setting it to 1 minute.
Put your Yoga to sleep (the power button should blink), wait 60 seconds,
notice the laptop fan spins up for a second, then all is quiet (the power
button no longer blinks).
Congratulations! Your C:\ drive is now 112 GB in size.
