hddguy: Thanks for the info,
Business is primarily IT support managed services and retail to businesses, Started out years ago, then resolved a few logical issues. Bought get data back and r-studio etc and things moved on.
Don't have a shop only an office, Don't charge clients for diagnosis, don't do the work unless I have practiced it previously and do outsource or recommend they go elsewhere if I cannot do the work.
Have resolved seagate busy errors thanks to the kind info provided here and have also been successful in some cases where diodes have blown, and also with the samsung bridging fixes.
Have amassed over a hundred faulty drives with which to test / open and learn from. And have now the funds to allow.
Already have PC3000 flash for usb sticks, and an Aoyue 852A+ station. Have a clean cabinate, bench and tools, one head swap tool from HDD tools and awaiting PC3000 for windows and UDMA data extractor.
I understand that having the knowledge to use the above will take time. I do hope that I am more than crawling, however as you say not quite running yet.
Thats why I joined to get involved and learn rather than lurking.
Thanks for taking the time to reply.

best
Logical.
