<strong><p>Hi,
|
||
</p></strong>
|
||
|
||
|
||
<p><strong>I have a 1.2GB Hard Drive. It has a few Bad Clusters, which
|
||
are mostly at the end of the drive. Everytime I use <TT>Scandisk</TT> it
|
||
freezes on 99%. All my programs run fine, but sometimes they freeze
|
||
and I have to reboot the computer. I assume it is accessing data
|
||
from the bad clusters and it freezes sometimes. I thought <TT>scandisk</TT>
|
||
was suppose to mark bad clusters and tell the computer not to use
|
||
them. Is there any way that is really safe where I can either
|
||
seperate or put all those bad clusters away so that the computer
|
||
doesn't use them and store data on them? I would appreciate your
|
||
help. This one has stumped me. Thank You!
|
||

<BLOCKQUOTE>This may seem like an unsatisfying answer --- but you
|
||
should probably be aware that
|
||
"<A HREF="mailto:linux-questions-only@ssc.com">linux-questions-only@ssc.com</A>" is
|
||
for the "<a href="http://www.linuxgazette.com/">Linux Gazette</a>
|
||
Answer Guy." I volunteer my time to answer questions that related to
|
||
Linux. I do that to show my appreciation for all the effort that Linus
|
||
Torvalds, Alan Cox, Stephen Tweedie, Ted T'so, and hundreds of other
|
||
programmers have put into creating the operating system that
|
||
I use. </blockquote>
|
||
|
||
|
||
<BLOCKQUOTE>I do NOT volunteer my time to answer questions that are
|
||
purely about Microsoft's operating system (or any other
|
||
proprietary software, for that matter). The companies that
|
||
produce these products can pay for their own support staff.
|
||
If they choose not to do so, or are otherwise unwilling or
|
||
unable to provide you with support that meets your needs
|
||
--- you should probably reconsider your purchasing decisions.
|
||
</blockquote>
|
||
|
||
|
||
<BLOCKQUOTE>Sigh!</blockquote>
|
||
|
||
|
||
<BLOCKQUOTE>Since I suffer from a compulsion to answer questions
|
||
thoroughly here's a few suggestions:
|
||
</blockquote>
|
||
|
||
|
||
<BLOCKQUOTE>Your obvious alternative would be to replace that
|
||
drive with a newer, less defective one. Normal, modern IDE
|
||
and SCSI drives have extra sectors on every track which are
|
||
"mapped" over any bad sectors on that track. Thus it is
|
||
relatively rare for bad sectors to be visible to the operating
|
||
system's drivers. You could put the new drive in as the
|
||
"master" and you could install Linux over the old drive ---
|
||
just to learn more about it.
|
||
</blockquote>
|
||
|
||
|
||
<BLOCKQUOTE>Another alternative would be to use something like
|
||
the <a href="http://www.symantec.com/">Norton</a> Utilities.
|
||
Perhaps one of those is more robust than the
|
||
accessories that came with your OS.
|
||
</blockquote>
|
||
|
||
|
||
<BLOCKQUOTE>If none of that works, backup your system, re-install the OS
|
||
from scratch and see if the re-FORMAT detects and properly
|
||
handles these bad sectors --- or re-partition, make the last
|
||
partition a couple of percent smaller and then re-install.
|
||
</blockquote>
|
||
|
||
|
||
<BLOCKQUOTE>If you don't have a backup system which is sufficiently reliable
|
||
and of sufficient capacity to do a full system backup and
|
||
restore --- then you're hopeless.
|
||
</blockquote>
|
||
|
||
<blockquote>While we're on the subject of "hopeless" --- it may
|
||
seem awfully curmudgeonly of me, but surely <em>some</em> of these
|
||
options must have occurred to you. I really hope that you
|
||
weren't actually "stumped" by this!
|
||
