When an Intel® Solid-State Drive (SSD) with firmware that does not support TRIM is installed in a computer with an operating system that does support TRIM, the SSD will function normally. However, SMART errors might be experienced after updating the SSD firmware to a version that does support TRIM. After the firmware update, the operating system detects the TRIM capability that may cause SMART errors from managing data blocks differently.
After updating the firmware without TRIM support to one supporting TRIM, the operating system should be reinstalled. Prior to this reinstall, the SSD needs to be erased using a low level formatting utility. A low level formatting utility, such as CMRR Secure Erase*, will completely erase the NAND flash memory and all data on the drive. Important: Backup any additional data in addition to the operating system on the drive before initiating the low level format or the data will be lost.
Firmware versions prior to 2CV102HA (26 October 2009) did not support ATA Data Set Management Command “TRIM”.
