Buffalo TS4200D NAS Firmware 3.42 for Mac OS

Bug Fixes

- Email Notifications: Fixed a bug where notification emails were not sent after the device is updated from firmware version 3.20 or earlier to version 3.41.
- UPS: Fixed a bug where the TeraStation did not properly sync with a UPS.

Before updating the firmware:

- Do not turn off the TeraStation until the firmware update is complete and the "finished" message is displayed.
- USB drives may not be mounted automatically after updating the firmware. To mount them, unplug and then reconnect them.
- Disconnect iSCSI volumes with the iSCSI Initiator before updating the firmware.
- Make sure the TeraStation's Ethernet frame size is smaller than the hub or router's. Larger frame sizes may not transfer the data to the TeraStation correctly.
- If an external USB drive is configured as a target for TeraStation backup, the drive should be formatted with ext3, XFS, or FAT32. Do not use an NTFS-formatted drive as a backup target or unexpected behavior may result.
- If a "Replication I33 ReplicateFailure" error occurs, navigate to 'Backup' - 'Replication' and click 'Run Differential Backup'.
- If a "I33 ReplicateFailure" replication error occurs, navigate to 'Backup' - 'Replication' - 'Edit Failover Status' and click 'Sync'.

About Network-Attached Storage Updates:

Upgrading the Network-Attached Storage (NAS) firmware can improve the system’s overall performance, stability, and security by adding various fixes for related issues, enhancing existing features (or adding support for new ones), or updating different applications.

Due to the high number of NAS manufacturers, as well as network storage types, installing a new firmware might not be always as easy as it appears – and not too safe either. Failing to perform a software update can cause serious malfunctions to the network storage.

So, before you even consider applying this release, carefully read the installation guide and initiate the process only when you have understood and completely familiarized yourself with all the steps.

Moreover, it would be best if you take into account using a UPS unit (Uninterruptible Power Supply) to perform this task, because no power disruption should affect the upgrade.

With all these aspects in mind, after you have read the installation guide, click the download button to apply this firmware version to your NAS. Remember to check back with our website in order to stay up to speed with the latest releases.
