Hi there!
|
||
|
|
||
|
<br><br>
|
||
|
I got a neat, fast 1,6GB HDD (WD IDE) with one "bad cluster" as DOS
|
||
|
calls it. Is there any way in using it for linux(marking the cluster as
|
||
|
bad or something like that?)</strong></p>
|
||

<blockquote><img src="../gx/dennis/bbub.gif" alt="(!)" width="50" height="28"
|
||
|
align="left" border="0">No
|
||
|
problem. Linux distributions come with a program named '<tt>badblocks</tt>'
|
||
|
it handles this for you. The best way to do it is to let '<tt>mkfs</tt>'
|
||
|
call badblocks using its internally supported switches.
|
||
|
|
||
|
<br><br>
|
||
|
For ext2 filesystems you'd use <tt>mke2fs</tt> or <tt>mkfs.ext2</tt>
|
||
|
(usually links to the same file). Just add the <tt>-c</tt> switch to
|
||
|
the command when you invoke it (and read the man page for details).
|
||
|
|
||
|
<br><br>
|
||
|
If you already have an ext2fs on a drive and you suspect that new bad
|
||
|
blocks have developed (for example you've dropped the drive or the
|
||
|
machine's been through an earthquake) you can run <tt>e2fsck</tt> (or
|
||
|
<tt>fsck.ext2</tt> as it may be linked) with the <tt>-c</tt> switch.
|
||
|
|
||
|
<br><br>
|
||
|
Like I said, easy!
|
||
|
|
||
|
<br><br>
|
||
|
(Naturally I suggest you do these from single user mode, and do
|
||
|
proper backups).
