error code 0142
There is a code 2000-0142 that means the hard drive test was unsuccessful, and to reconnect the hard drive and run the test again.
error code 0f00:0244 and error code 0f00:1a44
Those are also hard drive error codes, i believe.

That is normal. If you want to have audio while in safe mode you can google that. There are some youtubes about it.
