拯救有問題的硬蝶 - BBS

我有一顆硬碟 可以讀取寫入
可是有時常常跑到一半就會重新開機
(ex:p2p)

我用
#dd if=/dev/ad1 of=/dev/null bs=16m
結果是

dd: /dev/ad1: Input/output error
2+0 records in
2+0 records out
33554432 bytes transferred in 4.318729 secs (7769515 bytes/sec)

我安裝了
/usr/ports/sysutils/smartmontools來檢測
結果是:

=== START OF READ SMART DATA SECTION ===
SMART overall-health self-assessment test result: PASSED <-- health??
.................(略)....................

Error 237 occurred at disk power-on lifetime: 13336 hours (555 days + 16 hours)
When the command that caused the error occurred, the device was in an
unknown state.

After command completion occurred, registers were:
ER ST SC SN CL CH DH
-- -- -- -- -- -- --
40 51 59 00 55 01 f0 Error: UNC 89 sectors at LBA = 0x00015500 = 87296

Commands leading to the command that caused the error were:
CR FR SC SN CL CH DH DC Powered_Up_Time Command/Feature_Name
-- -- -- -- -- -- -- -- ---------------- --------------------

c8 00 80 00 53 01 f0 08 1d+07:19:53.552 READ DMA

出現上面的訊息

最到我到sysinstall下 fdisk重新用一遍

#dd if=/dev/ad1 of=/dev/null bs=16m
結果是

dd: /dev/ad1: Input/output error
2+0 records in
2+0 records out
33554432 bytes transferred in 4.318729 secs (7769515 bytes/sec)

我在猜這顆硬碟是不是壞軌,freebsd上重新格式化也不能避免使用到壞軌嗎??
我爬文結果 是直接放棄換一個 想看看有沒有強者的經驗分享
