ฉันเป็นผู้ใช้ของ Oracle Virtualbox บน Ubuntu และฉันเคยคัดลอกไฟล์ vdi เป็นข้อมูลสำรอง ก่อนหน้านี้ฉันทำสิ่งนี้ (คัดลอกไฟล์ vdi แล้วคัดลอกกลับมา) หลายครั้งโดยไม่มีปัญหา
แต่วันนี้ฉันพบข้อผิดพลาดนี้
VirtualBox VMs/win_7$ cp ../../Bkps/win_7.vdi .
cp: error reading ‘../../Bkps/win_7.vdi’: Input/output error
cp: failed to extend ‘./win_7.vdi’: Input/output error
ฉัน googled นี้เล็กน้อย แต่จากคำแนะนำเกี่ยวกับปัญหาที่คล้ายกันฉันไม่ได้ลดความน่าเสียดายอะไรลงไป ใครช่วยแนะนำวิธีแก้ปัญหานี้ได้ไหม
ผลลัพธ์จากdmesg
is (และฉันไม่เข้าใจอะไรเลย)
