I wonder if anyone else has encountered issues with constant bus errors being thrown when writing (including copying within the device) to a CF card in a PCMCIA-to-CF adapter in a PCD-50B SCSI card reader?

-External SCSI box has a terminator attached.

-The PCD-50B does not provide TERMPWR...but that shouldn't be a huge issue on the SE/30, right?

-Reading CF and writing to disk seems to work fine.

-Generally doing whatever you want on the hard disk does not result in bus errors ever, no matter where it's connected along the bus. System is rock-stable.

-Writing to the CF is not always a problem, in that I have an OS installed on the CF and it's bootable, but once it starts bus erroring it never stops. I've had the OS installer crash a few times and had to retry.

-Disk First Aid comes up clean on the CF.

-I've tried different sizes/brands of CF cards but there seems to be no difference.

-I have the same issue no matter if the CF drive is on the internal SCSI bus or the external.

-I have not noted any behavioral differences between System 7.0, 7.1.1 or 7.5NAD.

Baffling! Suggestions greatly appreciated!
