I've had this same issue with a 3.5" 6TB WD Green formatted as a single partition as exFAT as well as erased and formatted as a single partition as HFS+. Hack will hang and won't post if the drive is in an external enclosure and connected before the computer is past the Clover Bootloader. Once macOS is loading/loaded, the drive will show up fine and Hack will work normally if connected then. In my experience this only is an issue with external drives that require external power. All 2.5" portable drives I've tested can be connected before the bootloader without any issue.New challenge/issue... and this may not be the thread to post on but I'll share because it is occurring on my continuing build.
I have a 250GB Samsung mSATA installed as my boot device. I've had a 120GB Kingston SSD in the drive caddy and formatted it exFAT. Everything has been great. I recently decided to buy a Seagate 4TB HDD to replace the Kingston in the caddy.
I plugged the Seagate into a USB3 port on the rear and reformatted it as GUID partition, with exFAT, using Disk Utility.
I then replaced the Kingston with the Seagate in the caddy (after removing it from its external enclosure of course), and powered up.
Here's the kicker... the BIOS post won't complete. I then took the drive back out of the internal caddy, placed it back into the external enclosure, plugged it into USB again, and powered up. Again, USDT will hang on post.
IF I disconnect the drive completely, the USDT goes past post normally and I'm up in macOS in about 14 seconds.
I can then plug the drive in and it is recognized! If I reboot, USDT will hang on post if the drive is attached.
What's going on? This does NOT happen with the Kingston (a 120GB drive..... is it capacity related? Seagate? Is there something the BIOS is trying to scan?)
Update: Tried also with 320GB HGST, works fine, gets past post, etc.
Update: Tried also with 1TB Crucial SSD, works fine, gets past post, etc.
Update: Tried different USB enclosures (OWC and Sabrent)
BIOS is 3.04
Once I removed the 6TB from its enclosure and connected it via internal SATA and power, it worked fine. Is the port you're using on the USDT an eSATA port? I wonder if it's still seeing it as a removable source, which is why it won't boot. I'm using a CMT, so I'm not sure if your model has an additional SATA as opposed to eSATA. Curious to know too if anyone has a solution to this.
edit: capacity of WD Green
