Why is a single disk still configured as RAID1?

[Tricky]

I am in the process of trying to recover a lot of movie files from a disk that going faulty/being corrupted and it was configured in the F5-221 NAS as single disk yet its in RAID1 format and there are mirrored files from the separate RAID array that's in the NAS so can someone tell me why?

Was it configured as RAID1 before?

No freshly formatted HDD.

Is there any screenshot of the storage pool and volume you can show us?

[Tricky]

No i haven't but dont see what a screen shot would prove ? other than you dont believe it was configured as a single disk!

Like i said can you explain how a HDD configured as a single can have RAID files present its says to me that there is something wrong with the way the TNAS handles mixing RAID and single disks.

Yes, the system default SINGLE disk actually is a RAID 1 with only one drive. What problem with your files now?

[Tricky]

As i said in my first post i am finding files on the single disk that should have only been on the two HDDs set up as RAID1 and i am asking why this should happen? never seen this on other NAS when setup as single disks or JOBD.

May I know what kind of files you found been mirrored from another array? Would you show me a list of screenshot?

[Tricky]

Cant do that I'm afraid as after running recovery software and being able to see the files present i would then be asked to pay £250 to recover fully so its easier just to re rip the DVDs again so i just formatted the disc and SFAICS the disk that was reported as faulty by the TNAS is OK i am starting to wonder about the TNAS as i have had countless problems since buying it...most of it with data corruption.

As for the files present they where a mix of documents, JPEG s and audio files that are also present on the RAID array.

That's alright. Let it be, we will find some other ways. thank you!
