1. 硬盤問題引起的訊息原因可能很多
1-1. 變壓器 5v 7v 12v 電壓不穩或太低
1-2. 電源線與硬盤接觸不牢
1-3. 訊號線與硬盤接觸不牢
1-4. 硬盤內部有硬件瑕疵
1-5. ...

2. 如果 atax.00 有好幾個
sudo ls -l /sys/block/sd*
可以核對是哪個硬盤

引用:

tail /var/log/messages

3. atax.00 的錯誤訊息 /var/log/messages 不一定有記錄
/var/log/syslog 看看

这下好,彻底不能进入系统了.
如何抢救?

这个电脑安装的双系统，可以在win下面登录，因此排除硬盘的问题。
在linux下面，10次尝试，只有1次可以成功登录。

1. ata6

引用:

cat /var/log/syslog
部分信息

1-1. 沒有 ata5 ata6 訊息
也許這個時候正常了
也許發生的時間點沒有寫入記錄

引用:

sudo ls -l /sys/block/sd*
lrwxrwxrwx 1 root root 0 Nov 12 12:46 /sys/block/sda -> ../devices/pci0000:00/0000:00:1f.2/ata5/host4/target4:0:0/4:0:0:0/block/sda

2. ata5

3. 你有幾個硬盤 ?

Nov 12 12:44:09 hws dbus[754]: [system] Activating via systemd: service name='org.freedesktop.UDisks2' unit='udisks2.service'

4. 請提供 Ubuntu 版本

5. 你有沒有三用電錶 ?
查一查 5 v / 7 v / 12 v 電源線是否穩定
量得的電壓必須穩定大於 5 v / 7 v / 12 v
5-1. 電源供應器
https://zh.wikipedia.org/wiki/%E9%9B%BB ... 9%E5%99%A8
5-2. 周圍環境用電量大時電壓容易不穩定或低於標準值

ata5 等於 sda5 ?

ata5 應該是指硬盤或 U 盤
這幾篇有比較詳細的介紹
1. http://unix.stackexchange.com/questions ... -represent
How do I correlate /dev/sd devices to the hardware they represent?
2. http://serverfault.com/a/480031
by checking dmesg and /dev/disk/by-id

可以肯定，硬盘没有问题，因为我的双系统，win7可以正常进入。
请看这里的输出，很有趣
