Partial updates for shingled magnetic recording devices

A system, comprising:

• a storage device comprising a shingled magnetic recording (SMR) storage zone;
• and
• a host computer connected to the storage device, wherein the host computer is configured to:
• receive a command to delete data stored in the SMR storage zone of the storage device;
• responsive to receiving the command to delete the data, reset a write pointer for the SMR storage zone;
• receive a command to undo the deletion of the data;
• and
• responsive to receiving the command to undo the deletion of the data, undoing the deletion of the data, wherein the undoing the deletion comprises using a partial write pointer update to set the write pointer for the SMR storage zone to a write position after the data stored in the SMR storage zone of the storage device.

A computing device comprising a processor and a memory storing instructions that, when executed by the processor, cause the computing device to perform operations, the operations comprising:

• receiving a command to delete data stored in a shingled magnetic recording (SMR) storage zone of a storage device;
• responsive to receiving the command to delete the data, resetting a write pointer for the SMR storage zone;
• receiving a command to undo the deletion of the data;
• and
• responsive to receiving the command to undo the deletion of the data, undoing the deletion of the data, wherein undoing the deletion comprises using a partial write pointer update to set the write pointer for the SMR storage zone to a write position after the data stored in the SMR storage zone of the storage device.
