SYSTEM AND METHOD FOR PREVENTING ERRORS INA STORAGE MEDIUM

摘要

The system and method for preventing write errors in storage mediums includes detecting the presence of an early power fail (EPF) signal derived from a power supply circuit providing power to the storage device. In response to the EPF signal, a modified standby-immediate (MSI) command is issued to the Storage device controller circuitry. The storage device controller circuitry responds by causing the storage medium to finish the current write operation and cease all future write operations. In this manner, write errors are prevented by causing the storage device to cease write operations before the expiration of predetermined time period between the issuance of the EPF signal and actual power failure.
