Fixes:
Wear Leveling Issue: When the host continues to issue write commands to a particular LBA area and the wear-leveling process is executed in a different area, the drive may encounter the below failure mode. Once a drive falls into this failure mode, it cannot be recovered by power cycle.
Cause: This issue was introduced by applying the wear-leveling-related change in the previous firmware. Data buffer is used for data transfer during Wear-Leveling. Firmware may detect overflow of this data buffer during the refresh process or data transfer process if a read error happens on the block where wear-leveling is in progress. The drive goes into failure mode once the data buffer overflow is detected.
Fix: Fixed the FW to make consecutive Wear-Leveling processes not overlap each other to prevent the occurrence of data buffer overflow. Write Cache Issue: An issue that may cause firmware downloads to fail in the event of a capacitor failure. This failure is triggered by firmware download in the Write Cache Off state, and even if it occurs, it does not lead to drive failure and can be recovered by a reset or Power cycle.
Cause: When FW Update is executed in the Write Cache Off state and then restarted, capacitor discharge control is activated. In this case, unintended PLP occurs because capacitor discharge was controlled in the order of capacitor discharge and then PLP interrupt mask.
Fix: When capacitor discharge control is executed after FW Update in the Write Cache Off state and the system is restarted, the PLP interrupt mask is changed to control in the order of PLP interrupt mask and then capacitor discharge.
