Received a SanDisk Ultra Plus 256g from Newegg.ca today. Took it straight out of the box, and on advice from other forums, checked for firmware updates using SSD Toolkit 18.104.22.168. Toolkit recommended firmware update.
Created a bootable USB Drive. Attached the SSD to a SATA port and booted to Firmware update… After running the update, the Updater reported “Firmware update of SanDisk SDSSDh2256g Failed”.
Tried firmware update using a bootable CD created by Toolkit which resulted in the same failure.
The error output displayed on screen after the toolkit exited indicates the toolkit was unable to download the firmware update to the SSD drive.
The updater did not display version of available firmware update, only stated that an update was available. The toolkit detected firmware version X211200, which agrees with the current firmware version listed on this page: http://kb.sandisk.com/app/answers/detail/a_id/6053#ultraplus
Please advise whether the error indicates that the update is not applicable to the SSD model I purchased, or that the SDD is defective and must be replaced. Note that I have not formatted or initialized the SSD in any way, perhaps that’s the cause?
I have also reported this error to SanDisk customer support, and I will add Thier response to this thread.
