debian的Load_Cycle_Count

原来以为只有ubuntu的硬盘管理有问题,没想到debian的也有。问题和解决方法如下:
mvision:~# smartctl -a /dev/sda |grep Load_Cycle_Count && date
225 Load_Cycle_Count 0x0032 100 100 000 Old_age Always – 3251

mvision:~# smartctl -a /dev/sda |grep Load_Cycle_Count && date
225 Load_Cycle_Count 0x0032 100 100 000 Old_age Always – 3253
Tue Dec 4 21:20:08 CST 2007
mvision:~# smartctl -a /dev/sda |grep Load_Cycle_Count && date
225 Load_Cycle_Count 0x0032 100 100 000 Old_age Always – 3254
Tue Dec 4 21:21:21 CST 2007
mvision:~# smartctl -a /dev/sda |grep Load_Cycle_Count && date
225 Load_Cycle_Count 0x0032 100 100 000 Old_age Always – 3255

mvision:~# hdparm -B 254 /dev/sda

/dev/sda:
setting Advanced Power Management level to 0xfe (254)
mvision:~# smartctl -a /dev/sda |grep Load_Cycle_Count && date
225 Load_Cycle_Count 0x0032 100 100 000 Old_age Always – 3255
