In the OP's case we could take an old Seagate drive and use "set stuff" or the ATA DCO commands to disable DMA reporting. If the drive then functions properly within the Roland machine, this will be our proof of concept.

Identify Device (ECh)
If the device is an ATA device, then bit 15 [of word 0] shall be cleared to zero.
Devices supporting the CFA feature set shall place the value 848Ah in word 0. In this case, the above definitions for the bits in word 0 are not valid.
Identify Packet Device (A1h)
Bits (15:14) of word 0 indicate the type of device. Bit 15 shall be set to one and bit 14 shall be cleared to zero to indicate the device is an ATAPI device. Bits (12:8) of word 0 indicate the command set used by the device. This value follows the peripheral device type as defined in SPC-4 (e.g., 05h indicates a CD/DVD device).
Word.Bit Description
==========================
0.15 0 = reserved for non magnetic drives
0.14 1 = format speed tolerance gap required
0.13 1 = track offset option available
0.12 1 = data strobe offset option available
0.11 1 = rotational speed tolerance is > 0.5%
0.10 1 = disc transfer rate > 10 Mbit/sec
0.9 1 = disc transfer rate <= 10 Mbit/sec but > 5 Mbit/sec
0.8 1 = disc transfer rate <= 5 Mbit/sec
0.7 1 = removable cartridge drive
0.6 1 = fixed drive
0.5 1 = spindle motor control option implemented
0.4 1 = head switch time > 15 usec
0.3 1 = not MFM encoded
0.2 1 = soft sectored
0.1 1 = hard sectored
0.0 0 = ATA reserved (should be zero)

Word 0: General Configuration.
This field informs the host that this is a non-magnetic, hard sectored, removable storage device with a transfer rate greater than 10 Mb/sec and is not MFM encoded. CompactFlash products report 848AH in compliance with the CFA specification.

Easily converts any USB Thumb Drive or other external storage to standard ATA for quick and safe imaging, cloning or testing.
Designed, tested and built specifically to extend PSIClone functionality to USB attached storage.
Works with USB attached hard drives (external storage) as well as USB thumb drives.

No, such bridges are used in adapters which connect a USB host to an IDE ATA/ATAPI device. You need to go the other way round, ie you need to connect an IDE/ATAPI host to a USB peripheral. Such adapters are very rare.
