Ora si compra una ssd (propendo per una Crucial SSD 2,5 256GB, MX100 7/9,5mm a +- 100 euro).
Yosemite è innocente... e quindi lo reinstallerò da chiavetta). Grazie per i consigli.
A proposito, secondo Te col difetto che ha l'hd mi conviene utilizzarlo per emergenze o buttarlo (insomma è recuperabile per uso legggero di storage o si butta?)
