Ho un hard disk Samsung tipo "SP2514N 250GB/7200rpm/8M/PATA"
La scheda elettronica (BF41-00085A Rev. 10) ha la parte alimentazione con diodo per la tensione 12V. bruciato. ho sostituito lo stesso senza ottenere il funzionamento del disco.
E' possibile avere uno schema del BOARD oppure la serigrafia dei componenti?
oppure il componente che esiste vicino al diodo (12V.) che cosa è visto che non si riesce a leggere. (E' una resistenza o un condensatore, di quale valore deve essere.
In attesa di una risposta (urgente, se possibile) saluto

That will only work if the HD's TxD pin swings between 0V and +5V. AFAIK, modern HDs use Vio supplies of 3.3V or 2.5V. I presume the value of Vio determines the TxD voltage levels.

I would look instead for a circuit that is based on Maxim's RS232C driver chips. Choose one that is specified for a 3.3V supply.
