I deleted a folder by mistake via the Pogoplug web interface. Since Pogoplug does not have any recycle bin feature, I connected the hard drive to my computer directly and tried to use some Undelete softwares

I tried a a few undelete/restore softwares but none of them was able to find this folder. The undelete/restore softwares was able to find files and folders i deleted several months ago but was unable to find this folder.

What do I do? My understanding was Pogoplug deletes the folder normally like a windows Shift + Del (Since they dont have a recycle bin option). If such is the case, I would have been able to recover the folders.

Anyone have any suggestions?
