সুতরাং আমার কম্পিউটারে আমার দুটি ড্রাইভ রয়েছে, একটি এইচডিডি (সিগেট ব্যারাকুডা এসটি 2000DM001) এবং একটি এসএসডি (কর্সার ফোর্স 3 120 জিবি)। তারা উভয়ই 3 বছর বয়সী এবং আমি ভেবেছিলাম তাদের দীর্ঘতর হওয়া উচিত, বিশেষত এইচডিডি। যদিও আমি স্বীকার করি যে আমার কম্পিউটারটি PSU এর সাথে সমস্যার কারণে রুট শাটডাউন নিয়ে বেশ কিছু সময়ের জন্য সমস্যা হয়েছিল।
তবে আমি যখন তাদের স্মার্ট ডেটা পরীক্ষা করেছিলাম তখন তারা উভয়েরই কিছু ক্ষেত্রে "প্রি-ফেইল" রয়েছে। এখন আমি জানি যে সমস্ত ক্ষেত্র ততটা গুরুত্বপূর্ণ নয় তবে সঠিক ব্যাখ্যা (বিশেষত এসএসডি এর জন্য) খুঁজে পেতে আমার বেশ কষ্ট হয়েছিল।
আরও কি, এইচডিডি মনে হয় স্ব-পরীক্ষায় ব্যর্থ হয়েছে। আমি সিগেটের সিটুলস সরঞ্জাম এবং স্মার্টলেট (বাশ) সহ একাধিক প্রোগ্রাম দিয়ে চেষ্টা করেছি।
সুতরাং এখানে প্রশ্নগুলি: আসল পরিস্থিতিটি কতটা গুরুতর? ড্রাইভগুলি কি সত্যিই ব্যর্থ হওয়ার সম্ভাবনা রয়েছে? যদি তা হয় তবে আমি কি কেবল ব্যাকআপ নিয়েছি এবং এটি হওয়ার জন্য অপেক্ষা করা উচিত বা এএসএপকে পুরোপুরি প্রতিস্থাপন করা আরও ভাল?
সময় দেয়ার জন্য ধন্যবাদ
