I have absolutely no idea what it means, and I never use any ethernet cable because i have a wireless connection, but it's relentless. I have gone through F2 and F12 and all the settings are perfectly fine. BIOS order is fine with HDD on the top.
If you have tested the HDD in an external HDD case and other notebook without success the case is clear: The HDD must be replaced because it’s faulty!
I can understand you that you want your data recovered but what do you want to do if you are not able to access them? In this case you need help from a special data recovery laboratory but this is not cheap and cost hundreds of Euro.
I’m wondering that you don’t have a backup. Did you never try to do this or thought it would be useful?
Last but not least a new HDD can be ordered from an authorized service provider in your country or every computer shop. Satellite L300 supports 2.5” SATA HDDs.
