एक सप्ताह के दौरान, 3TB सीगेट ड्राइव (ST3000DM001-1CH166) के लिए, smartd ने धीरे-धीरे बढ़ती हुई संख्या को अपरिवर्तनीय और वर्तमान में अपठनीय (लंबित) क्षेत्रों की सूचना दी, फिर एक घटती संख्या, जब तक कि गिनती 0 नहीं थी और त्रुटि स्थिति थी रीसेट। लॉग से (केवल परिवर्तन दिखाते हुए):

इसके अलावा, वास्तविक क्षेत्र की गणना भी 0 है, इसलिए सेक्टर फिर से मैप नहीं हुए हैं। यहां smartctl -a

मैंने डाउनलोड किया है, लेकिन अभी तक ड्राइव पर सीटू नहीं चला है, लेकिन ड्राइव की वर्तमान स्मार्ट स्थिति मूल रूप से ठीक लगती है। इस तरह के व्यवहार का क्या कारण हो सकता है?
अद्यतन: भविष्य के पाठकों के लिए, ड्राइव वास्तव में कुछ महीनों के लिए ठीक था, जिस बिंदु पर अधिक क्षेत्र अचूक / ऑफ़लाइन हो जाते हैं, और वास्तविक क्षेत्रों की संख्या 0 से परे बढ़ने लगी थी, और स्मार्ट लॉन्ग सेल्फ-टेस्ट एक पढ़ने के साथ असफल होने लगे त्रुटि। इसलिए ये संदेश एक उपयोगी प्रारंभिक चेतावनी के रूप में दिखाई दिए।
