讨论下THE FOLLOWING DISK SECTORS COULD NOT BE READ的问题

emuplay

我有一台做radi 5的机器，前几天突然出现　
CANNOT READ: BLK 119832172
CONTINUE? [yn] y

THE FOLLOWING DISK SECTORS COULD NOT BE READ: 119832172, 119832173,
cannot read block bitmap
** Phase 1 - Check Blocks and Sizes
DANGER: Filesystem being checked is larger than the device in which it is
        stored (/dev/root). The filesystem is 62907989K while the
        device is 59916079K. Backup filesystem and recreate as soon as possible.
** Phase 2 - Check Pathnames
** Phase 3 - Check Connectivity
** Phase 4 - Check Reference Counts
FREE INODE COUNT WRONG IN SUPERBLOCK
FIX? [yn] y

** Phase 5 - Check Synchronous Write Log
** Phase 6 - Check Free List Bitmap

CANNOT READ: BLK 119832172
CONTINUE? [yn] y

经检测发现有一块硬盘损坏，换后用fsck修复后仍出现这个错误，从字面语句理解是不能从某个扇区读取数据

这种情况下有什么好的办法检测呢？现在不影响系统使用，但我总是不放心。
