I’ve bought on the cheap some time ago a networked hard disk, and only after buying it was I told that it was windows-only.
I tried to plug it (through ethernet) on the Turris Omnia but it’s not recognized by lsblk and nmap finds only three things on the network, apparently the wifi card, the ethernet one and my laptop (so no external disk).
Is it a lost cause or do I have a chance to make it work ?
The first thing would be to figure if it forms a link. Check the output of dmesg before and shortly after attaching it. If it will show some “link up”, you’re connected and you only need to figure what IP address it uses etc. It might be easiest to factory reset the drive, if it has such option (it should).
