In fact, the kernel has deprecated support for SATA under IDE and the
"modern" SATA support is under SCSI.  On my system, the BIOS shows
my SATA interface as a 3rd IDE intf but nevertheless my Linux kernel
uses SCSI.  Granted, it's not an external USB device, but I still think it
would be worth double-checking what support you have configured into
your kernel, and also compare how your Debian host is accessing the
disk as with the lsmod command, for example.
