Buongiorno,
ho acquistato a ottobre un disco SSD (OWC Mercury Accelsior PCIe SSD) per il mio Mac Pro (Mid 2010). Fino a maggio tutto OK. Poi si rotto (non pi partito). Essendo ancora in garanzia me l'hanno sostituito con uno identico ma il nuovo ancora mi d problemi. IN verit di per s funziona ma dall'utility disco mi continua a dire che deve essere riparato. Lo riparo e due giorno dopo il problema permane. Cosa consigliate di fare? Chiedere una nuova sostituzione con un altro SSD (come consigliato dall'azienda da cui ho acquistato)? Oppure chiudere gli occhi e tenerlo finch va.... (ma per quanto?).
Incollo qui l'esito di EntreCheck. Forse pu essere utile per capire se c' qualcosa che gli d fastidio.....
Grazie!!!!!
eccolo,
