Had great success using 6 guitar picks instead of the putty knife. Allowed me to move in smaller sections and caused zero damage to the iPod. Didn't even bend any metal clips mentioned in Step 21! Replacing a damaged drive with 128 GB of flash memory using StarTech 1.8-Inch ZIF to CF Adaptor and Komputerbay Dual Micro SD to CF adaptor. Can use two cheaper 64 GB SD cards to achieve a solid state 7th Gen Classic!
