ScanDisk, lost cluster

S

SANTANDER

Some applications hung up, so I restarted computer. After restart, system
start ScanDisk to check hard drive for errors. In log file, there was some
info:

File system: There was one lost cluster. ScanDisk reclaimed the lost cluster
as free space.

Does this mean logical error, not physical damage of disk surface? Is it
safe for hard drive?
Does it possible find the damaged file and remove it?

How to make Thorough test without fixing anything?

Thanks,

This is normal and safe. Every cluster=logical sector of the
hard drive has an identifying number. The FAT (= File
Allocation Table = directory of contents) is a record of
filenames and the numbers of every sectors used by every file
(in sequence.) Your ScanDisk process discovered a single
logical sector (out of thousands) listed nowhere in the
FAT but not shown as "free space" -- therefore marked
it "free space" i.e. free to use. That is all.

No file is damaged and nothing need be "removed."

Set appropriate check boxes on the ScanDisk main panel.

Go to the hard disk manufacturer's web site and download their diagnostic software
respective to your hard disk. After the test, you will know if the hard disk is bad or
not..

The disk storage is logically divvied up into "clusters". Clusters typically
contain 2 to 64 KB or more of storage. Each cluster has an address. Logical
data is mapped to those physical storage addresses in the "File Allocation
Tables" (FATs). There is

'Yes', 'no damage', and 'yes'.

The damage, if any, was already mostly cleaned up. This was the rest of
cleanup.

This error results from the FAT not being completely and accurately updated
during some past disk operation. If you get cross-linked files, for
instance, you usually get lost clusters, too. Or, if a crash left a
non-saved file that "almost disappeared", or otherwise interrupted a disk
operation. The garbage may have been around a while, too, and not from this
crash.

Sorry, I thought you were asking about a command-line prompt. It's the only
way to do exactly what you asked to do.

If do a ScanDisk Thorough test: there is an 'Options' tab, where is 2
checkboxes below: 'Do not perform write-testing', 'Do not repair bad sectors
in hidden and system files'. Should we check it? Will it better do test in
Safe Mode?

Thank you,

These are boxes for fairly sophisticated diagnosticians to use. 'Do not
perform write-testing' is much faster, but also only returns half the data
you're looking for. However, if you know enough to know you don't need the
missing half, who cares?

I too wanted and still would like to run through all the testing
before fixing anything, but with time I've gotten a lot more
confidence in Scandisk, and drives are so large that I no longer want
to take the time to test without fixing.

8 or 10 or more years ago when I was having a lot of crashes and using
versions of Eudora email that didnt' do well in crashes, I had my
options set to not change lost clusters into free space, but to make
files out of them. Then I would use the List command** to look
quickly at all of the new files, and occasionally I would find whole
mailboxes that either were copies of mailboxes I still had, or in a 3
or 4 cases were THE mailbox, when it was missing from Eudora. In one
or more cases I was able to actually restore the mailbox, and in
others I was able to rename the file and keep my mail all in one
sequential file, not easy to use but better than nothing in case I
needed it.


**part of Norton DOS and I forget the real name under which it is
marketed. Why a command or program like this isn't available from
other writers I don't know. Without List or the equivalent, browsing
say 100 big files is very time consuming. "List" is a DOS command
that doesn't provide the ability to edit, so there is no need to copy
the file to a work area, which takes a lot of time. And it doesn't
care what the extension is, or have any tendency to look at a file in
a web broswer or .gif editor. It just looks at the raw data,
simultaneously in hex and in display mode or whatever the opposite of
hex is. One can just look at the file where it is, and there is no
limit to the size of the file. So with one finger on the Page Down
button and another on the Escape button, going back and forth from
finger to finger, one can look at 100 megs of data spread over 200
files in 10 minutes or less.

Eventually I learned more about how data is stored and that much that
looked like I needed it was just a copy of what I still had. But I
would wait a few weeks before doing any of this to see if a mailbox
for example was missing, if I couldn't remember what mailboxes were
open during the crash. But Eudora was been fixed I guess years ago
because this hasn't happened for years, despite some freezes and
crashes. I mention it because you seem like you are interested in
all this nuts and bolts stuff.

But I havent' come across data that I need for years, and, partly
because I don't have List installed on this computer, usually just
wait a month or two to see if anything comes up missing, and then just
delete the files I've created with scandisk, which makes them back
into free space.

And then delete those chk files, since, AFAIK, they are generally of no use.
Although sometimes (if they were originally text files) you can recover
something, if it was otherwise deleted.

No, then you LOOK at those CHK files using WordPad and try to figure out
what's in them and maybe identify what file(s) were lost. Once you've
gleaned all the info you can (and even perhaps saved some important data),
THEN you can delete them.

Whenever it's happened and I've looked at them, about the only thing I've
ever been able to glean is some text out of it (from a word processor type
of file). I've never been able to recover or use its data, except to get
an idea of what I was writing at the time. Outside of that (and that
ain't much!), it's always ended up being useless for me. Have you had
some different experiences?

Yeah, I've actually managed to recover quite a bit of lost word processing
that I was able to clean up. But you're right that they're almost always
garbage.

getting at.

Others with better tools could likely read what we can't. Would be helpful
to know the name of a file that's been trashed. Or, from the code, at least
the general subject matter.
