very first thing to do is to make sure hidden folders, files and protected operating system files are visible on your computer.

remove the drive and copy all data (including system) to your computer using a USB IDE caddy

Install the ssd in your audya and format it. (init phase error will appear due to the lack of system files). Check the LED in the disk section is not on and solid red, if so the drive is not compatible. it should only flash green when writing/reading to the drive. (in addition, the ide cable may need to be modified to accept an SSD disk select)

once formatted the folder structure will be intact but no content.

remove the drive and connect to a pc with a usb caddy. manually copy files and folders (except the hidden system folder) that you saved from your Audya drive

once complete, copy the content of system folder except audio drums. do the audio drums seperately to avoid possibility of cyclic redundancy errors.

Alternatively just purchas an official SSD upgrade which are fully approved and require no modifications or file copying...just install and go.

NOTE: any USB updates installed will no longer work with the SSD (user or factory SSD) and will show as CORRUPT STYLE. Whats more, the USB drives used to install the styles will also fail to operate. This is because they are copy protected to the old hard drive. You will need to speak to your local distributor for help here.
