Sony SVT11213CXB - Manual (Page 160)

If you reduce the volume of the C: drive partition, you may not create Recovery Media or
complete the recovery process successfully because the free space on the built-in storage
device is not sufficient.
1. Open Control Panel, select System and Security, and select Create and format hard
disk partitions under Administrative Tools. (See Opening Control Panel to open
Control Panel.)
If the User Account Control window appears, select Yes.
2. Right-click the C: drive and select Shrink Volume.
3. Enter the size of the partition to be created in Enter the amount of space to shrink in
MB and select Shrink.
4. Right-click Unallocated and select New Simple Volume.
5. Follow the on-screen instructions.
Hint
If you are signed in to your VAIO computer as a standard user, you may be prompted to
enter an administrator name and password.
Creating Other Drives (Modifying Partitions)
Partitions are divided areas on your built-in storage device. Dividing the built-in storage device
into more than one partition may have various advantages, such as separating the system files
from your data files.
Your VAIO computer has only one partition (C: drive) as the factory default setting.
If you want to store data in another partition, such as D: drive, change the partition size and
create a new partition.
For more information on how to create partitions, see
Creating Partitions .
Hint
Some models may have D: drive as the factory default setting.
Removing Recovery Content to Free up Disk Space
Your built-in storage device contains the recovery area where the data for system recovery is
stored. If your VAIO computer includes a solid state drive (SSD), you might want to minimize
the recovery area by removing such data to free up disk space on the C: drive (or the last
drive in your drive list, for example D: drive).
You need Recovery Media to remove the data for system recovery or to recover the computer
after you remove the data.
Note that removing recovery content makes it impossible to use the refresh function.
