The disk at SCSI #0 has been remove while in use

Normally my Mac Classic II works just fine. But if I connect up a spinning disk to the external port and attempt to copy a large number of files off to the internal SCSI2SD I get the error message "The disk at SCSI #0 has been remove while in use" and the SCSI2SD disconnects. I end up rebooting to correct the issues.

 

I'd have to crack the machine open but I believe the SCSI2SD is powered via the old HD power. It has no internal spinning disk.

 

What I may be doing wrong is not supplying external termination and assuming the drive is doing it. I pulled the drive from a Mac II and just adjusted the SCSI ID to not conflict with my SCSI2SD so I could back up the contents. Is this incorrect?

 

I believe I have had this happen before when I was copying files between two SCSI2SDs but i can't remember the exact circumstances. If I copy files in small batches I notice it happens when a specific file is copied from the spinning disk.

 

Anyone else seen this? I'm starting to wonder if its a SCSI2SD firmware bug with a specific bit of file data coming off the disk.

That last part is pretty fascinating.  Like that file includes a secret bit sequence that tells the SCSI2SD to shut itself off?  (Sorry I don’t have anything real to contribute here, I just think it’s interesting.). Does the SCSI2SD die every time you copy just that one file by itself?

So far I found two files. I'll see if either are something I can share. One is an old FileMaker database that may have private information in it. The other seemed to be in the preferences folder.

 

So far I have been stuffing the whole hard drive and it's going on 10 hours with no issues. It seems to be past the two files. Oh how far we have come with speed of our computers.
