Many PCs ship with OEM-installed partitions whose purpose can be puzzling.
Here’s a description of two common types of OEM partitions — and how to handle them as they apply to backups, System Restore, and the like.
Do OEM partitions need routine maintenance?
Allen Benton hit a snag when following the how-to in the July 4 article, “What makes ‘Restore Previous Versions’ fail?”
- “My system has a SYSTEM_DRV and a Lenovo_Recovery partition. Should I enable protection for them?”
Generally, the drives and partitions you want to protect are those whose contents change as you use the PC — your C: drive, for example — or any other drive/partition with stored user files and data. If the contents of drives and partitions don’t change, then it doesn’t need much protection.
In your case, SYSTEM_DRV is where Lenovo (and some other manufacturers) put boot files and the Windows Recovery Environment, which lets you launch Windows’ built-in repair modes in case of trouble (Microsoft info). These files rarely, if ever, change.
Lenovo_Recovery (and similarly named partitions from other manufacturers) contains the factory-recovery software and data files. These are the programs and files you use if you want to wipe out everything on your PC and return the system to its as-delivered state. Factory-recovery files usually never change.
