• Changes made in version 0009 (m4 can be updated to revision 0309 directly from either revision 0001, 0002, or 0009)
• Correct a condition where an incorrect response to a SMART counter will cause the m4 drive to become unresponsive after 5184 hours of Power-on time. The drive will recover after a power cycle, however, this failure will repeat once per hour after reaching this point. The condition will allow the end user to successfully update firmware, and poses no risk to user or system data stored on the drive.

If you are using a SAS Expander please do not download this Firmware. As soon as we have a Firmware Update that will work in these applications we will release it.

Change Log:

• Improved product reliability.
• Resolved performance anomaly which resulted in brief, intermittent pause in drive response time for some users.

Note: This is firmware from Revision 0006 to Revision 0007. It will not work for updating between any other versions. If your drive has Revision 0001 firmware, then you MUST first perform the intermediate step of updating to Revision 0002. If your drive has Revision 0002 firmware, then you MUST first perform the intermediate step of updating to Revision 0006.

Change Log:

• Improved power management
• Improved power-up behavior after uncontrolled power-down
• Improved full drive and corner-case performance
• Improved TRIM behavior

Note: This is firmware from Revision 0002 to Revision 0006. It will not work for updating between any other versions. If your drive has Revision 0001 firmware, then you MUST first perform the intermediate step of updating to Revision 0002.

Change Log:

• Improved Power Consumption
• Improved TRIM performance
• Enabled the Drive Activity Pin (Pin 11)
• Improved Robustness due to unexpected power loss
• Improved data management to reduce maximum write latency
• Improved Performance of SSD as it fills up with data
• Improved Data Integrity

Note: This requires a Low Level Format to the SSD which will erase any data on the drive.
Please ensure that your data is backed up prior to performing the Firmware Update. We are hopeful that future Firmware revisions/updates will not be destructive.

Change Log:

• Added support for LBA to NAND bank mapping
• Additional improvements made to update process.
• Additional improvements made to firmware bad block management.
• Corrected several ATA Security bug fixes.
• Corrected how some SMART commands were displayed
• Added support for additional NAND manufacturers, capacities, and configurations.
• Made further improvements to TRIM and wear leveling algorithm

Change Log:

• Fixed issue that sometimes causes firmware download problem
• Fixed issue that could cause 256GB to be corrupted
• Eliminated performance degradation over time with Wiper with 1819 FW
• Fixed issue where the power cycle count was incorrectly being reported with 1819 FW
• Fixed issue where some SATA 1 hosts weren’t correctly identifying the hardware
• Fixed issue found in simulation (not in the field) where the free block count was incorrectly being reported
• Fixed issue with remaining life not being properly displayed on SMART information
• Added support for additional NAND manufactures and capacities
• Made further improvements to wear leveling algorithm

Change Log:

1. Updater runs out of DOS instead of Windows
     1.1 Added ATA8 ACS2 TRIM Support
     1.2 SATA Rx SSC is turned off by default, Now Rx and Tx SSC both off
     1.3 IDENTIFY word 69 bit 14 is cleared (Non deterministic trim)
     1.4 IDENTIFY word 60-61 are changed (User addressable logical sectors for LBA28)
     1.5 FPDMA error return code was not adequate
     1.6 SMART related changes were made (BBM error log was removed)
     1.7 SATA error handling code was enhanced
     1.8 Added paired page calculation for Micron 34nm MLC NAND
   
2. Bug Fix: Fixed a bug in error handling in Set Multiple mode command
3. Bug Fix: Fixed a bug that caused 1.5Gbps diagnostic failure
4. Bug Fix: SMART related bugs were fixed
5. Bug Fix: Current ATA security state was not reflected in IDENTIFY information
6. Bug Fix: Performance boost routine reused the recently used block and it did harm to wear leveling.
7. Bug Fix: During SATA protocol, abrupt OOB made Controller hang
8. Bug Fix: In bad block management, wrong number of free blocks is used and it led to timeout and hang
9. Bug Fix: After STANDBY_IMMEDIATE, most host controllers wait for OOB reply for 100ms. Sometimes Indilinx Barefoot firmware couldn’t answer to COMRESET because FTL initialization took longer time. This bug caused Windows Sleep/Hibernate test failure.
10. Bug Fix: Various read fail scenario were found with FTL simulation
11. Barefoot ECO chip support code was added
12. More NAND ICs supported
