Please read all instructions below carefully before proceeding for information that may affect your specific computer.
It is always highly recommended that you backup your data. Your data must exist in multiple locations to be qualified as having a back up. Anytime a drive is being updated, upgraded or moved, there is a potential for data loss. This update is non-destructive for any SSD already partitioned for NTFS or FAT32 and while OWC has updated several drives with no data loss, we strongly recommended backing up all data on the SSD before performing this update. See the FAQ at the bottom if you are unsure if your drive is currently set for NTFS/FAT32. Instructions to verify your firmware version.

If your OWC SSD Firmware revision contains xxxA12F0 or xxxA13F0, then xxx365A12F0 or xxx365A13F0 is the most up-to-date revision, current as of October 20, 2011.

If your OWC SSD Firmware revision contains xxxABBF0, then 541ABBF0 is the most up-to-date revision, current as of March 5, 2014.
