corrupted .asf file

hi all


I have an avi file that got was lost after a file partition.


i have recovered the file via getdataback, but not it will not play in any player that i have tried.

wmp states the following:

Windows Media Player cannot play the file. The Player might not support the file type or might not support the codec that was used to compress the file.



Does anyone know ANY way I can recover this file???

 

I have no idea but you could try Alltoavi or AviMux_Gui to create a new avi to try. In AviMux_Gui, open the avi, highlight it and select generate data. In the lower window, highlight audio and select start, take's less than a minute. Both free but unless this avi is close to the original size, I doubt it and even if it is, I don't know. I'd try with another player too, WMP return's that error to me quite often where Media Player Classic is fine, VLC in the past too. (both free too)

 

Not a clue.

 

How did the file get damaged in the first place?
How big is the file?
Is it ntfs or fat32 partition? Did you continue to use the disk
after the file was lost - if so it's probably been overwritten.

You can look at it in a hex viewer and skim through. You'll
probably find clear text, binary zeroes, and other stuff that
obviously belongs to other files.

 

hi there

It was an NTFS partition. file is 284KB. I did not use the disk as it did not have an OS on it, was just a storage drive. Only used it when getdataback was recovering the file.

Can you give me any tips on a suitable hex editor and what I am looking for to try to recover it?

 

I still don't understand how the file got this way.
Was this a data partition that you formatted? How was the file lost?
Did you recover the file to a separate disk/partition?

The fact that it's NTFS and small is helpful.

Open Virualdub/tools/hex editor. Scroll down in the file and see
what you can see.

 

i run 2 hard drives. the main one runnign the o/s and a second storage drive.


i had a prob with the primary drive and reinstalled windows, but in my stupidity i format partitioned the storage drive! The second I pressed the button I realised what I'd done. Annoying.



Anywho, Im not too clued up on hex editors. What am I looking for??

 

the storage drive is curently "empty" and i recovered files back to the primary drive. Im in the process of puuting all recovered data on a separte external drive, but some avi files work, some do not.


I got a couple that are really important that dont seem to work. hence my posts...

 

i am using hexedit at the moment.


i havent got a clue what im looking at however. just a load of jumbled letters and numbers..

 

Here's some things to look for in the Hex viewer.
Right at the start you'll see the avi header (this one is xvid),
2nd image shows the end of header/padding, and beginning of
the actual data. 3rd, close to
the bottom of the file, end of data immediately followed by
the Index Block. 4th, from within the Hex
viewer, Edit/Riff chuck tree, show the address where each of these
sections start.
In general, your file is quite small. You might be able to see
something by starting at the top and just scrolling down.

Between the header and data, they may be zeroes, that's OK.
But once the data starts (picture 2) it should look pretty much
as you see. If you see readable, clear text or more binary zeroes,
your recovery has picked up some garbage.

 

thanks for the info. here is a screenie of the corrupted avi from the hex editor. mine looks nothing like that!!

 

That's a shame. It's hard to tell if that's part of an avi at all.
DO you have any other tools you can try ?
I've got a simple, free, program on my PC called Restoration.

Unfortunately, can't find a link. If you want to give it a try,
I can put it on a file hosting site.

 

do you think its worth copying in a woking avi header? looks like the corrupted avi has no header at all!

 

Take a look at the following info. Perhaps they'll be something
useful:

ok thanks for your help!

 

grrrr


so i found out that its actually a corrupted .asf file....not an avi. does that change anything?

 

Look for some asf repair tools.
Look at a known good file. I found one on my system and took a look
in the hex viewer. There is some text at the beginning,
suggesting some header info.

I don't see that in the piece you posted.

 

odd. i know the original corrupted file was .asf

the recovered file is in .avi format. i tried to convert it, but the tools im using does not recognise it as a valid avi
