如何解决防止MySQL数据从死机HD迁移的错误？

我正在尝试从死机HD恢复MySQL数据库。我已经按照这里关于复制旧文件的指示进行操作：https : //stackoverflow.com/questions/40479395/export-mysql-datatabase-from-a-dead-hard-drive-xampp，但是我得到以下信息错误日志中的错误消息：

旧数据库为5.5.40，新数据库为5.5.54，因为我无法成功安装完全相同的版本（安装程序不再需要下载链接）。错误是仅仅是.cnf文件中指定的大小，还是掩盖了其他内容？

感谢@ITSolutions，我解决了这个问题。

我cnf在C:\Program Files\MySQL\MySQL Server 5.5\my.ini（位置有时可以不同）上找到了我的文件。

我进行了以下更改（注意注释掉的原始值），然后重新启动了MySQL服务。

# InnoDB, unlike MyISAM, uses a buffer pool to cache both indexes and
# row data. The bigger you set this the less disk I/O is needed to
# access data in tables. On a dedicated database server you may set this
# parameter up to 80% of the machine physical memory size. Do not set it
# too large, though, because competition of the physical memory may
# cause paging in the operating system.  Note that on 32bit systems you
# might be limited to 2-3.5G of user level memory per process, so do not
# set it too high.
#innodb_buffer_pool_size=38M
innodb_buffer_pool_size=108M

# Size of each log file in a log group. You should set the combined size
# of log files to about 25%-100% of your buffer pool size to avoid
# unneeded buffer pool flush activity on log file overwrite. However,
# note that a larger logfile size will increase the time needed for the
# recovery process.
#innodb_log_file_size=19M
innodb_log_file_size=54M

它在几秒钟内加载完毕，我的所有数据都可以再次访问！
