Sorry to hear your LX60 has given so much trouble with the SATA!
While it is common for the SATA connection to go "bad" once a year, it is very
strange that yours goes out as often as you describe. This is not normal. Do you live in very humid area? You might consider trying a new cable from a computer shop. Yes, you will need the service disc and service remote to install a brand new HDD. The used HDD you want to try may need to be completely erased, including the formatting, on a computer before putting it in a recorder: the recorder can get confused and lock up if there are any PC files on the HDD.
The LX60 was a "LuXury" model sold only outside North America: what country are you living in? The service remote can be difficult to find outside US/Canada. You need either Pioneer GGF1381 remote or Sony J-6090-203-A remote. The Pioneer is VERY expensive, the Sony is 1/3 the price and works just as well. Google the Sony to find web dealers who can ship to your country. The service disc is number GGV1321 Type 2, send an email to the Dutch Pioneer user site supportATpioneerfaqDOTinfo
to request help downloading a disc image.
Once you have the two service tools, this is the procedure to match the new HDD to your Pioneer:
1. If the recorder complains of an HDD ERR, you'll need to reset the CPRM code. Look on the rear panel for a secondary small white label with a nine-digit code number, its located near the fan or the AC socket. Write down the nine digits.
2. On your service remote, press ESC and then STEREO. Service mode will activate and a service display will appear on your TV. Enter the nine-digit number you wrote down using the service remote number keys, then press STOP.
3. Press ESC and STEREO again, enter the nine digit number again, and press SEARCH.
4. The recorder will ask for the ID Data Disc. Load the GGV1321 service disc and close the tray. After a moment, your TV should display "Rom Write OK!" (If your TV displays Rom Write NG! instead of Rom Write OK!, don't panic. Sometimes the recorder trips over itself, or you enter the nine digits in the wrong order, and have to start the CPRM process over again. It nearly always "takes" the second time around.)
5. Pres CLEAR on the service remote. The recorder will exit service mode. Remove the service disc BUT DO NOT CLOSE THE TRAY. Turn the recorder off, the tray will close itself. Wait a moment, and turn power back on.
6. Using your original remote that came with the recorder, go into the Disc Setup Menu while recorder is switched to HDD mode (not DVD). You will see an "Initialize HDD" option now available under HDD setting. Tell the recorder to initialize the new HDD.
Your LX60 should work normally with no ERR alerts from this point on (unless there is a very bad SATA connection problem in the unit).
