无法使用dd将一个SD复制到另一个SD


2

我有:

  1. 损坏的32GB微型SD卡-尽管尝试用(hdparm -r0 /dev/sdc)强制,但无法写入任何内容:

    EXT4-fs (sdc1): mounting ext3 file system using the ext4 subsystem
    EXT4-fs (sdc1): INFO: recovery required on read-only filesystem
    EXT4-fs (sdc1): write access unavailable, cannot proceed
    
  2. 新的32GB micro SD卡

如果我尝试将dd整个/ dev / sdc归档:

sudo umount /dev/sdc*
sudo dd if=/dev/sdc of=/hhome/os.img bs=4k

然后放回去:

sudo dd if=/hhome/os.img of=/dev/sdc bs=4k

我得到:

sdc: unknown partition table

而“破碎的SD”组成良好的分区表。

怎么了?


clonezilla可以克隆它吗?

您格式化了“新SD卡”吗?
