With clearing P-list data is not accessible, not lost. Data is save on the platters and can be recovered for good amount of money.
Fastest way to destroy data on hard drive just drill 5-6 holes trough platters.
Thete is no tool for moving platters with spacers. SD have one modified can tool but is useless.
For seagate with stuck motor HDD surgery have tool for that http://hddsurgery.com/spindle-replacement-tools
I prefer locally installed solution. It is faster and more secure. In case of internet outage database still can work :D
Will be nice to see progress for LoboX project
I use https://www.hesk.com
It is free, good forum support, costumable. It's not designed for Data Recovery but can do the job.
For invoices still use Excel.
On Drupal there is few projects available.
Because of those strange updates on Win10, I disable automatic updare on all PC's. I hate automatic restart during night, even PC is imaging or coping data.
