The ISD-300A1 is a USB to ATA/ATAPI bridge board that supports devices that comply to the ATA/ATAPI-5 specification. This includes devices such as hard disk drives, CD-R/RW, DVD, DVD+R/RW, DVD RAM, Zip, Magneto-Optical (MO), etc. The ISD-300A1 has been tested with a large range of devices from various manufacturers and while it will not work with every single device it will work with most. In the cases where incompatibilities have been found, normally the device did not comply with the ATA/ATAPI-5 specification in relation to a polling controller. In this scenario the manufacturer of the device is alerted to the issue so the problem can be fixed.
Please note that the ISD-300A1 is obsolete and the functional replacement is AT2LP. The AT2LP comply to the ATA/ATAPI-6 specification All the related collaterals of AT2LP can be found in the link here
