I would like to check bad sector of my hdd.
I tried to "chkfsys -u /dev/hd0".
see below..
#chkfsys -u /dev/hd0
Comparing new bitmap to old and checking released blocks
Directories Files Extents Blocks
Available 625142448/disk
Totals 2/disk 16/disk 19/disk 153307/disk
Maximums 19/dir 3/file 152623/file
Averages 8/dir 1/file 9581/file
NEW bitmap is equal to OLD bitmap
chkfsys is only show that string "NEW bitmap is equal to OLD bitmap".
But i want to find that bad sector is being or not.
How can i know bad sector's being?
Please help.
Thank you. |

oh... i found "dcheck"
# use dcheck
dcheck - check a disk for bad blocks (QNX)
dcheck [-lmpqrvwV] [-L loops] [-f first_blk] [-b blk_cnt] [-B blks_per] drive
Options:
-l Loop until input (switching SERIAL/RANDOM).
-L loops Loop (as above) for a maximum number of loops.
-m Mark bad blocks (in /.bad_blks) (opens disk drive READ/WRITE).
-p Pause before starting.
-q Quiet mode; don't display progress information.
-r Utilize a random head movement algorithm.
-v Verbose; display every bad block on the disk.
-w Write after read test (opens disk drive READ/WRITE).
-V Verify write after read test (opens disk drive READ/WRITE).
-f first_blk First (beginning) block to check.
-b blk_cnt Total (maximum) number of blocks to check.
-B blks_per Number of blocks per read (default: 32).
Where:
drive is the name of the disk (as: /dev/fd1, /dev/hd0, /, etc) |
