Hello everyone.

Sorry for the delay in responding.

Alright. I have tested the recorder at a friend's house and it works fine. My computer still does not recognize it and the other WD HDD. So far, I have only reset the Bios from the jumper, but now I will remove the battery for 10 seconds to see if things change.
I have read that it may be a problem with the power supply as well. I have a thermaltake 680W and I have never had problems of this type with the previous motherboard that powered it.

Regards.

EDIT: The recorder now works on my computer. Something is something.
