Storage management

The default configuration for 2big Dock is RAID 0 and formatted exFAT. After following the instructions to install Toolkit, you are prompted to review the RAID and format settings with the option to change one or both. See the LaCie Toolkit user manual for more details.

Since changing RAID and format are data destructive actions, Toolkit only offers to change them upon first use with the assumption that you have not written files to the storage. To make changes to the RAID at any time, please use the LaCie RAID Manager software. See Manage RAID for more information.
