MySql 读取 DaaDir 错误，因此无法访问它

Question

我刚刚下载了适用于 Windows 10 的 mySql 5.7 win32 x86

在“my.ini”中我设置了以下值:

basedir="D:\databases\MySQL-5_7(x86)"         
datadir="W:\b-databases\MySql\5.0.x\data"

但是，如果我尝试在管理模式下打开 CMD 并输入:mysqld --console

我收到错误:

D:\databases\MySQL-5_7(x86)\bin>mysqld --console mysqld: Can't change dir to 'W-databases\MySql\5.0.x\data\' (Errcode: 22 - Invalid argument [OS Error Code : 0x7b]) 2017-02-02T23:47:18.575846Z 0 [Warning] TIMESTAMP with implicit DEFAULT value is deprecated.

D:\databases\MySQL-5_7(x86)\bin>

但是，检查消息，可以看到 MySql 尝试访问路径 W-databases\MySql - 即它删除了驱动器部分...

我该如何解决这个问题并解决错误的原因？

我只想更新新的 MySql 版本并继续使用我现有的 5.0 db

看起来它以某种方式将 \b 解释为退格键。尝试不使用引号，或使用正斜杠，或两者兼而有之。
