I've had a Pi 3B+ for a few years, running OMV and with a 2TB external SSD plugged in (SATA to USB cable). Worked fine.
I've almost finished setting up a new Pi 4, again with OMV. Last time I did this, the external drive was blank. Now it's got a lot of stuff on there that I don't want to lose.
OMV has mounted the drive ok and the OMV dashboard shows it as 37% full, so I guess the old files are all still present. I created a shared directory called "Share" using the SMB/CIFS button, but AFAIK this is a brand new shared folder which bears no relation to the existing files on the drive.
I can't work out how to make them show up - for example, in Windows File Explorer I've been able to map the NAS to a Z: drive but while I can see the "Share" shared folder fine, it's empty, and the remaining folders and files on the drive aren't visible, presumably because I haven't shared them (using OMV) - because I don't know how to!
Can someone help please? I suspect the solution is very simple but I don't know what it is.
Thank you.
