I am not an expert on this, but I do own an AE 3.5"HD drive. It is definitely
NOT a SCSI drive. As far as SCSI standards go, I have seen for myself good
cross-compatibility with Hard Drives between different controllers (as long)
as they use the RIGID DISK BLOCK standard Commodore unified close to a
year ago. In other words, if they have the right information and follow
this standard, any controller should be able to read another controllers
partitions just fine. Also, most controllers handle removable media. A
friend just bought a new A3000. He had previously bought an IVS trumpcard
SCSI sysquest system. It plugged right into the A3000 scsi controller and
worked correctly from day one. Even understood the cart had been removed.
