I have a u310 ideapad with a 500GB HDD + 32GB SSD running windows 7.

Here is the disk and partition info:

In windows there are 2 drives:

C drive is Partition Disk #1, Partition #1

D drive is Partition Disk #1, Partition #2

I have researched a fair bit about how lenovo partitions the disks for use with the one key recovery feature. I have also been reading about Intel Rapid Start technology.

What I still do not understand is:

What is the 200MB partition for? (Partition Disk #1, Partition #0)

What is this 19.34GB partition for? (Partition Disk #1, Partition #3)

Why does the SSD size and partition only appear as 8GB (as reported from within windows) but in the BIOS it says that it is 32GB? (Partition Disk #0, Partition #0)

Does this have something to do with rapid start technology?

When I bought the machine, I thought that windows would be installed on the SSD and that I would have access to it for installing software. The machine does wake from sleep and boot incredibly fast so maybe i will leave it in its current configuration.

But I am curious about reinstalling windows on the ssd. So if I were to do that:

How should I go about re-formatting the drives and partitions in preparation for re-installing windows onto the ssd?

If I install windows on the ssd do I still need to install and configure Rapid Start technology?

Thanks!

Hi

Welcome To Lenovo Community

Based on what I read from your post, I am sharing few details which may help you understand the technology

200MB partition

The partition holds system files and bootable files that are essential to boot the Windows 7 properly in the event of the need to recover the OS in the event of corruption. It is called as System Reserved Partition

The SSD is used for Caching. It’s managed by the Intel RST Tool. The driver configuration consists of  

 Cache volume size + Data volume size

This is created for making system startup 3x faster in case of standby, shutdown.

The Hibernation partition must be at least the size as the installed memory (RAM)

Please refer below link SSD U310

Intel Start User Guide for understanding the working

 http://download.intel.com/support/motherboards/desktop/sb/rapid_start_technology_user_guide.pdf

If system is working perfectly as per the standard and you are happy with the performance, I would suggest not making any changes

If you are planning to install windows on SSD .Please follow the below guide for reinstalling windows on SSD

http://78.9.150.202/pub/RapidDrive.pdf

Before making any changes please create a set of recovery DVD’s

Do give this a try and let us know  

Hope This Helps

Cheers!!!
