Mac doesn't recognize new SSD external drive

I have an iMac with macOS Monterey 12.6 it will not show my external hard drive. The drive is recognized on the disk utility but when I try to mount it I got the following message "Could not mount “SSD”. (com.apple.DiskManagement.disenter error 49244.)". How can I fix this issue? It is a brand new Portable SSD Mobile Storage with 7TB

MacBook Pro 13″, OS X 10.11

forgive me if you already did, but did you format the drive before trying to mount it?


if no, please see Erase and reformat a storage device in Disk Utility on Mac - Apple Support
