mke2fs says "bad blocks count"

Hi,

I attached a virtual hard disk to one of my Linux boxes.
And after running creating partition on the new disk, I ran the following command:

Code:

mke2fs -t ext3 /dev/sdb1

While executing that command, it says as below and quits:

Code:

mke2fs: bad blocks count - /dev/sdb1

FYI,the output of fdisk is as below:

Code:

fdisk -l /dev/sdb
Disk /dev/sdb: 1073 MB, 1073741824 bytes
255 heads, 63 sectors/track, 130 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

   Device Boot      Start         End      Blocks   Id  System
/dev/sdb1               1         130     1044193+  83  Linux

Why is this mke2fs reporting such and is not able to create file system ?

The 'bad blocks' message generally indicates that mke2fs is unable to write to at least portions of the device. You can try to map out bad blocks using the slower '-c' option. If it still fails, you'll need to try the (much slower) '-c -c' options.
