Recovery of a failed file transfer between a host and a data storage device

A host device comprising:

• a) a device interface for coupling with a peripheral device
• b) a data-transfer manager for managing inter-device data-transfer operations via said device interface;
• c) a recovery-data archiver, operative:
• i) before an aborted outgoing inter-device data-transfer operation:
• A) with a target peripheral device that is coupled to said host device via said device interface, and
• B) which subsequently corrupts said coupled target peripheral device;
• and
• ii) in response to a request to commence said outgoing inter-device data-transfer operation,
• to store, on a host side of said device interface, at least one recovery data object selected from the group consisting of:
• iii) system data of a peripheral-device-residing storage-system data structure which is subsequently corrupted by the aborted data-transfer operation;
• and
• iv) a handle to a clean location on the peripheral storage device which is not subsequently overwritten by the aborted data-transfer operation and where said system data resides;
• and
• d) a peripheral device repairer, operative, in response to a subsequent coupling between the host device and the peripheral storage device that occurs after said peripheral storage device is corrupted by said aborted outgoing data-transfer operation, to repair said corrupted target peripheral storage device using said host-side stored at least one said recovery data object.

A computer readable medium having stored thereon computer readable program code for causing a host computer device to recover from an aborted outgoing inter-device data-transfer operation from the host computer device to a target peripheral storage device which corrupts the target peripheral storage device, the program code being operable to cause the processor to:

• a) prior to the corrupting of the target peripheral storage device and in response to a request to commence the data-transfer operation, storing, on a host side, at least one recovery data object selected from the group consisting of:
• i) system data of a peripheral-device-residing storage-system data structure which is subsequently corrupted by the aborted data-transfer operation;
• and
• ii) a handle to a clean location on the peripheral storage device which is not subsequently overwritten by the aborted outgoing data-transfer operation and where said system data resides;
• and
• b) in response to a subsequent coupling between the host device and the peripheral storage device that occurs after the peripheral storage device is corrupted by the aborted outgoing data-transfer operation, repairing the corrupted peripheral storage device using said host-side stored at least one said recovery data object.
