मेरे पास एक सहकर्मी से एक भ्रष्ट माइक्रोएसडी कार्ड है। उन्होंने मुझे संभव हो तो अपना डेटा बचाने के लिए कहा। मैं हाल ही में USB- मल्टी-कार्डरीडर का उपयोग करता हूं। 32 जीबी स्पेस के साथ माइक्रोएसडी एक उच्च क्षमता वाला कार्ड है। मुझे लगता है कि यह एक भ्रष्ट विभाजन तालिका या कुछ इसी तरह की है ...
मैंने टेस्टडिस्क का उपयोग करने की कोशिश की, लेकिन डिवाइस का पता नहीं चला है क्योंकि यह स्पष्ट रूप से बंद हो जाता है (डीजीएसजी लॉग देखें)। हालाँकि जब मैं माइक्रोएसडी डालता हूं और टेस्टडिस्क काफी तेजी से शुरू करता हूं (डालने के तुरंत बाद), कार्ड का पता चल जाता है लेकिन यह अनुपलब्ध है और टेस्टडिस्क कैंट 2 सेकंड के बाद इसे ढूंढता है। (/ देव / sdd अब उपलब्ध नहीं है)
मेरा सवाल यह है कि मैं डिवाइस को अनलोड करने के लिए सिस्टम को कैसे रोक सकता हूं? क्या यह कार्डरीडर, ड्राइवर या लिनक्स सिस्टम द्वारा विनियमित है? क्या ऐसा कुछ है जो मैं स्वयं कर सकता हूं? या क्या आपको लगता है कि कार्ड तला हुआ है और मुझे इसे कचरे में डालना चाहिए?
जब मैं कार्ड सम्मिलित करता हूँ तो dmesg के माध्यम से निम्न आउटपुट होता है:
