The idea was to use the, for me until now, unknown serial TTL RS232 interfa= ce = to access a working disk. The benefit would be to use only 3 pins and simpl= e = ASCII commands through an integrated PIC UART (or a bit banged one) instead= of = using the (S)ATA interface. I hoped that if it is possible it might already be done by now (that is rea= ding = and writing to a working hard disk, not trying to recover a broken one). /Ruben =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D= =3D=3D=3D=3D=3D Ruben J=F6nsson AB Liros Electronic Box 9124, 200 39 Malm=F6, Sweden TEL INT +46 40142078 FAX INT +46 40947388 ruben@pp.sbbs.se =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D= =3D=3D=3D=3D=3D -- = http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
