I used a terastation to format a usb disk in ext3 format. Everything was fine. I could read/write/share the disk over the network.
Then I plugged the disk into a PC with linux. The linux system was able to recognize it and everything was still fine.
Then I moved the disk back to the terastation. This time things went wrong. The terastation does not recognize the disk format so cannot read from it (to be more precise, it sees the disk but says the format is "Not Obtained"). I did not change anything when using the disk on the PC. The only thing I did was to play some music files.
From my experience, terastation seems to only recognize disks formatted by itself, but in this case, the usb disk was formatted by the terastation. Just having the disk read once by a different system seems to render the disk unreadable by the terastation.
I wonder if there is any fix, other than reformatting the disk, in order for my terastation to recognize the disk ( it has a huge amount of files on it and I want to share them over the network.) Thanks.
