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.

"Why?":

If misused, these APIs can corrupt or delete data.

"What?":

This capability is mainly checked by the file server for low level operations, e.g. RFormat, RRawDisk

"Where?":

File managers that include an option to format the memory card. Disk utilities. For other examples see: Sensitive Applications.

Notes:

  • 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.
