My X5000 uses filesystem NGF\00 as setup by Amedia-Computer. Next Generation File System I think.
Yeah, but NGFS has so far only been released for X5000s. When (if) it is released for other models, it will be as NGF\01, which is not (directly) compatible with NGF\00.
So SFS is the best available choice. The two variants only have the differences that SFS\00 has a max. partition size (124 GB, or something, IIRC; I think there's also a max. file size), but has some sort of repair/rescue tool working on it, while SFS\02 works with larger partitions/files, but has good and frequent backups as the only chance of recovery in case of trouble.
Best regards,
