# Using the Rescue Disk feature of Portable Inspector
### **Summary**
* * *
Use the Rescue Disk to examine your endpoint without launching your operating systems. It finds and removes persistent or difficult-to-clean security threats that can lurk deep within your operating system.
Rescue Disk can scan hidden files, system drivers, and the Master Boot Record (MBR) of your endpoint’s hard drive without disturbing the operating system. Rescue Disk does not load potentially-infected system files into memory before trying to remove them.
Take note that by default, Rescue Disk quarantines any detected threats to the local hard drive. If you wish to scan without writing any information to your local hard drive, change the scan action settings to Scan only.
