I restarted by deleting the SD and re-init.
I formatted the key after this init with msdos partitions ( and MBR) together with the macOS Diskprg. So the encrypted area is empty. macOS/Spotlight has created some dot-dir to save the index.
Now here is the first strange thing when I want to configure my hidden volume:
Nitro-App is suggesting to use between 14% and 55% for my first volume, while in the selection fields a range between 70% and 90% is pre-filled.
(BTW: allowing to also use MB/GB as unit is a great step forward! )
Second strange thing: The last sentence shows a value that is not changing when I change the values in the field. Does this sentence describe what 1% is from the average partition ? Then I would pout in bracket something like (1%=xxxMB) instead of only (xxxMB) - depending what you want to tell with that (xxxMB) thing today
When I want to activate the hidden volume, the dialog pop’s up that I should “Um Datenverlust zu vermeiden sollten Sie vor dem Fortfahren die Partitionen aushängen” What do you mean ? Shall I eject the encrypted disks ? do you want me to use diskutil in the Terminal to “eject” or to “unmount” or “unmountDisk” ? But remember, when ever I go into the terminal I get that disconnect message …
When I eject the encrypted disk (by moving the disk to the paper basket ) I get an error that the hidden volume could not be activated.
When I don’t eject the encrypted disk, I get the message that the volume is now enabled. But the disk portion program still shows the full encrypted disk - so that doesn’t work.
I created a new hidden volume and used the disk management tool to understand what is now mounted ( and what not). So the terminal window was not touched.before creating a new, I copied some data to the encrypted disk
Same procedure: enable encrypted , enable hidden, during the dialog I have ejected the encrypted with the disk mgmt tool and (Hurray!) an initialization request was shown. I initialized the partition with FAT32 - and MBR. Now the disk tool showed me the first partition ( as the hidden disk ) . I thought I also need to delete this partition, but there was no possibility to start that function ( it was disabled and the disk was not labeled)
I ejected the key and run through all partitions to view if the data is still available. That worked !! Hey, my first hidden volume created.
Ok, then I closed the disk management program and tried it again. I have ejected ( similar like in the disk manager ) the encrypted disk ( by moving to paper basket ) and we are back to zero: nitro-app was not able to enable the hidden volume.
Oh, Oh : After that I can unlock the encrypted disk, but it will not show up again . The macOS tells me that it can’t recognize the encrypted partition Even worst: when I say “Ignore” NK Storage is “dead” ( I think you have implemented a small heartbeat on it as the red LED is flashing very low, when the key is working. That blink is gone after hitting “Ignore”
Ok, now the encrypted partition is lost - when it is enabled, it shows the partition table in the disk management tool, but the first partition is gone.(including the data)
I stop testing now - but when I get more info I will post as an update
Ups - can’t eject any volume. I needed to reboot as after a hard eject no more mounts where possible. After the reboot I tried to look at the encrypted partition again: that worked fine. But when I tried to enable the hidden volume, this was shown ( I followed the working procedure above) BUT as content the data from the un-encrypted disk was shown ( in generic all META data from the first disk where mirrored as second disk )
So at the moment I can’t recommend to use hidden volumes on a macOS Sierra with Nitro-App 0.5.1
