Please note that as of October 24, 2014, the Nokia Developer Wiki will no longer be accepting user contributions, including new entries, edits and comments, as we begin transitioning to our new home, in the Windows Phone Development Wiki. We plan to move over the majority of the existing entries over the next few weeks. Thanks for all your past and future contributions.
Capabilities (Symbian Signed)/DiskAdmin Capability
The DiskAdmin capability is required to mount and dismount file systems, format media or get block level access to media with no filesystem mounted.
This capability can be used with developer certificates and Symbian Signed tested applications.
If misused, these APIs can corrupt or delete data.
This capability is mainly checked by the file server for low level operations, e.g. RFormat, RRawDisk
File managers that include an option to format the memory card. Disk utilities. For other examples see: Sensitive Applications.
- These APIs may look like a back door to bypass TCB, but file systems with open files can't be dismounted. The system drive always has open files when running the full OS.
