Dear,
Another option.
If there is a spare or another Enclosure model LS-XL/E . you may use it to initialize the none-enclusore model though the procedure is not official sloution.
Pull a Hard disk out from LS-X1.0TL and wipe all partitions clean. Next, put the Hard disk to Enclosure model.
Then Initialize the unit by using Enclosure model as if it is new by following initial setup procedure.
Finally, put Hard disk back to LS-X1.0TL.
In this case also buffalo will cancel warranty.
this options are not supported and any data loss is entirely end-user responsibility.
