Device Functions

Most device access functions can return any of the following device errors:

FS_ERR_DEV_INVALID_LOW_FMT

Device needs to be low-level formatted.

FS_ERR_DEV

Device access error.

FS_ERR_DEV_IO

Device I/O error.

FS_ERR_DEV_NOT_OPEN

Device is not open.

FS_ERR_DEV_NOT_PRESENT

Device is not present.

FS_ERR_DEV_TIMEOUT

Device timeout error.

Each of these indicates that the state of the device is not suitable for the intended operation.
