当我插入 SD 卡进行分区后执行 dmesg 时
[ 4611.940660] sd 7:0:0:0: [sdb] Assuming drive cache: write through
[ 4611.944440] sdb: unknown partition table
[ 4611.949411] sd 7:0:0:0: [sdb] No Caching mode page present
[ 4611.949419] sd 7:0:0:0: [sdb] Assuming drive cache: write through
[ 4611.949424] sd 7:0:0:0: [sdb] Attached SCSI removable disk
[ 4966.868425] end_request: I/O error, dev fd0, sector 0
首先，我认为这是因为 Linux 内核无法读取（内核存在一些问题），但是当我只是运行命令来获取分区详细信息时
sudo /dev/sdb [sdb is my device name ]
Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel
Building a new DOS disklabel with disk identifier 0x9b17bdaf.
Changes will remain in memory only, until you decide to write them.
After that, of course, the previous content won't be recoverable.
Warning: invalid flag 0x0000 of partition table 4 will be corrected by w(rite)
有人能给我解决这个问题吗？
