我正在尝试从旧驱动器中删除分区,但无论我做什么,它们似乎都保留了下来。在删除分区后应用更改时,gParted 会给出错误,然后显示完整的未分配区域,但之后当它完成扫描时,分区又恢复了。使用 KDE 分区管理器,我尝试的任何操作都会给出错误。我甚至尝试过调整分区大小和/或移动分区一点点,只是为了看看它是否会强制将分区表重写为可访问的内容,但没有成功。
从终端,我运行sudo dd if=/dev/zero of=/dev/sdb bs=512 count=1没有给出任何错误,但分区仍然存在。输出如下:
[sudo] password for admin:
1+0 records in
1+0 records out
512 bytes copied, 7.40531 s, 0.1 kB/s
我也跑了sudo dd if=/dev/urandom of=/dev/sdb bs=4096运行一段时间后,会出现以下结果,表明它能够写入一些内容:
dd: error writing '/dev/sdb': No space left on device
14651281+0 records in
14651280+0 records out
60011642880 bytes (60 GB, 56 GiB) copied, 80017.3 s, 750 kB/s
有什么想法吗?下面是显示驱动器结构的 gParted 捕获。
Model: IC25N060 ATMR04-0 (scsi)
Disk /dev/sdb: 60.0GB
Sector size (logical/physical): 512B/512B
