typedef EFI_STATUS ( EFIAPI * EFI_BLOCK_ERASE )

Erase a specified number of device blocks.

Parameters

[in]	This	Indicates a pointer to the calling context.
[in]	MediaId	The media ID that the erase request is for.
[in]	LBA	The starting logical block address to be erased. The caller is responsible for erasing only legitimate locations.
[in,out]	Token	A pointer to the token associated with the transaction.
[in]	Size	The size in bytes to be erased. This must be a multiple of the physical block size of the device.

Return values

EFI_SUCCESS	The erase request was queued if Event is not NULL. The data was erased correctly to the device if the Event is NULL.to the device.
EFI_WRITE_PROTECTED	The device cannot be erased due to write protection.
EFI_DEVICE_ERROR	The device reported an error while attempting to perform the erase operation.
EFI_INVALID_PARAMETER	The erase request contains LBAs that are not valid.
EFI_NO_MEDIA	There is no media in the device.
EFI_MEDIA_CHANGED	The MediaId is not for the current media.
