I am getting the above message when try to initialise a brand new external hard drive. The new drive is just the disk alone. I have tried the drive in a couple of caddies and get the same message.
The attached shows the full message
Any Ideas?

The short version is:
Connect the new external drive to the iMac.
Open Disk Utility click the small View box and select Show All Devices.
Under External select the Sabrent Media in the sidebar and then click Erase on the top bar.
Enter a Name: ____ , set the Format: APFS, set the Scheme: GUID Partition Map.
Click Erase button then click Done and close Disk Utility.
The long version is: at > Erase a volume using Disk Utility on Mac - Apple Support

Impossible to tell from here, if it is a drive problem or a caddie/enclosure compatibility issue.
What model is the PNY drive and what caddies/enclosures have you tried..?
What are your plans for this external SSD and caddie/enclosure setup...?
Maybe we can point you in a better direction for an external SSD or a DIY kit.
Ah' OK, I had a totally different picture in my mind.
So the Seagate is a 3.5" SATA hard drive...?
If so, then is sounds like maybe the Sabrent caddie is not up to the task and you need to use a different USB to SATA adapter or drive enclosure.
I'm also wondering, if you can install and independently format the Seagate drive in the Terramaster D5-300C...?
It sounds like a faulty External Hard Disk. Most experienced users on these forums prefer the following drive:
https://eshop.macsales.com/shop/owc-mercury-elite-pro which is really good for a general External Hard Disk or Time Machine drive. If you need fast performance, then you have a wide selection of the drives available from Macsales.com . Because they specialize in Macs everything they sell works. I'm in no way affiliated, just a long time satisfied customer.
The reason to use this drive is due to it's reasonable cost, reliability, and the vendor support. Personally I have some that are 15 years old that keep on working. When the internal HD dies (as you know they all do) replacing the HD takes about 2 minutes and only requires a simple screwdriver.
The drive is going in a Terramaster D5-300C which allows upto 5 drives. The new drive is a Seagate BarraCuda 8 TB. The drive will be used for storing photographs, from previous years, access is not on a regular basis. The pictures are also backed up on a NAS drive.
I get the error message quoted wherever the drive is connected. I will also try the drive connected to a windows machine to see if the error follows even on a different operating system, which if it does would rather suggest the problem is with the disk.
Thanks for you help.

Thanks for your quick response.
I have tried the new drive in the Terramaster and I get the same problem. The new drive is replacing an existing 4TB drive. The Terramaster already has 3 8TB drives with 2 4TB drives, one of which I want to replace.
Your help is much appreciated.
Thanks for the reply, I followed your instructions and got the same error as displayed in my original post.
I am beginning wonder whether the disk is faulty .
Thanks Robert
You’re welcome.
That is sounding more like a problem with the Seagate drive.
