Umbrel not detecting my SSD / but working

I freshly installed Umbrel in my Rpi4 and attached my 1TB ssd to it (which had 930gb space in it). But after successful installation, I can see in http://umbrel.local/settings that the Storage is only 4.4gb. What could be the issue?

So I tried to format the SSD using DiscUtility in my Mac. But it shows error “Cannot format because the disc cannot be unmounted”. I can access the data and see there is space in the SSD. I tried to format the SSD using my phone but that too was unsuccessful.

Now I tried to remove the ssd while the umbrel was on, and the system still shows 4.4gb of storage. This means the SSD is not being used at all?
The Rpi is working and Umbrel.local is available but the SSD is disconnected.

May I ask the make and model of the SSD?

WD Blue SA501 SATA SSD
I have used this same SSD to run Umbrel in past. But I had to stop the server and use this as media SSD for some time. Now I started Umbrel OS again and wanted to use it.
