Why does my Hard Disk Drive (HDD) capacity appear to be smaller than expected?
(This tip applies to Lenovo 3000 Y410, IdeaPad Y510, IdeaPad Y710, and Lenovo 3000 K100 Desktops)
Lenovo creates three partitions on the installed Hard Disk Drive:
1. The smaller drive commonly known as the C drive which contains Windows and your pre-installed software. The C drive should NOT be resized otherwise your OneKey recovery may no longer operate.
2. The larger drive known as the D drive which is ready for storing your personal data files such as videos, music, pictures etc. Both the C and D drives are visible in Windows but the D drive is MUCH larger to hold all your personal data. The C drive should NOT be resized otherwise your OneKey recovery may no longer operate.
3. The Service Partition (the partition without a drive letter) is used by the OneKey recovery system to backup and recover the C partition. This invisible partition requires only 18GB to 20GB of HDD space. The service partition should NOT be deleted otherwise your OneKey recovery will no longer operate.
One advantage of having these partitions is the protection of your personal data. In the event you need to use the OneKey recovery system, the personal data stored on the D drive will not be erased as the files on the C drive are restored.
Disk Management is an installed tool which will allow you to view these three partitions. You may access Disk Management by selecting Control Panel -> Management Tools -> Computer Management -> Disk Management.
* Actual size of the invisible partition may vary based on the model and preload.
