使用bbed修改块状态：

BBED> sum apply
Check value for File 6, Block 191:
current = 0x4293, required = 0x4293

再回数据库查看该表：

ZBDBA@orcl11g>select * from zbdba;
select * from zbdba
  *
ERROR at line 1:
ORA-01578: ORACLE data block corrupted (file # 6, block # 191)
ORA-01110: data file 6: '/opt/oracle/oradata/orcl11g/zbdba01.dbf'

常规坏块的处理方式：
1、event 10231
2、rowid抽取
3、DBMS_REPAIR

这里我用bbed修复该块：

BBED> p kcbh
struct kcbh, 20 bytes   @0 
 ub1 type_kcbh    @0 0x06
 ub1 frmt_kcbh    @1 0xa2

 ub1 spare2_kcbh    @3 0x00
 ub4 rdba_kcbh    @4 0x018000bf
 ub4 bas_kcbh    @8 0x005036cd

 ub2 chkval_kcbh    @16 0x4293
 ub2 spare3_kcbh    @18 0x0000

BBED> p tailchk
ub4 tailchk     @8188 0x36cd0601

这里tailchk信息正确，无需修改

坏块是没办法修复的，理论上只能通过格式化将坏块标记出来，电脑的格式化估计是不行的，用hp的u盘格式化工具试一下，希望可能不大

热心网友时间：2022-04-14 17:03

diskgenius 或者先下个硬盘检测器、呃，U盘插入之前最好杀下毒。

热心网友时间：2022-04-14 18:38

没修复过，你要不用低格工具格式化试试。

热心网友时间：2022-04-14 20:29

我的电脑，属性，工具，修复

看下是不是你把内容隐藏起来了如果不是得到话到百度里面搜索U盘修复工具有很多的
