I had a hard drive crash in 2003. I sent it off to get all data recovered they could salvage..
What I got back was a ton of crap on another HD I gave them.. All the extensions are jacked up and I burt it all to disc's and put them on a shelf...
During an internet conversation I had with someone years ago they had me send them a few files and they fixed them to open. Then they told me how to do it...
Yeah you know where I am going now.. That was in 2004.. Its now 2011 and I forgot what the heck I was supposed to do..
Anyway I have a crap load of filed on disc's labeled CRW files but nothing will recognize them or open them...
Any tech savvy gurus that are smarter than I am at this have any idea what I need to do?? Any software that might do it for me?
They're raw image files from older Canon digital cameras. Canon switched from the ".crw" format to the ".cr2" format somewhere around 2004. Recent versions of most image processing programs that handle raw images from Canon cameras will still open the older ".crw" format files.
Some programs that will allow you to open, view, and process ".crw" files include Canon Digital Photo Professional, Adobe Photoshop, Apple Aperture, and Picasa. (This isn't a complete list - there are others.)
I'm not exactly sure what you mean by "fix them to open", but any of the above programs can be used to produce ".jpg" files from ".crw" originals for use on the web or for use with some other program that can't read raw image files.
They were RAW CRW files on the hard drive when it crashed.. When the company saved some of the data from the drive these files were saved with the extension CRW but no program will open them.. Photoshop, Aperture, Preview, Photo mechanic or anything else.. They all say its an not a recognized file...
I still have old images, Raw and from the same camera, that open fine.. It is only the ones retrieved from my crashed HD. So something went wrong when they were retrieved.. Something was not saved right..

It might be as simple as changing the file extension. For example, a few years ago, when the .cr2 format was new, some file recovery programs would be able to identify a recovered file as some sort of TIFF file by examining its internal header data, but wouldn't recognize the internal "magic number" that identified it specifically as one of Canon's proprietary TIFF formats. So instead of naming a recovered file something like xxx123.cr2, they'd just name them xxx123.tif. Manually changing the recovered file's name from xx123.tiff to xx123.cr2 would make it accessible to programs expecting a Canon file format.
Do you know what camera produced the problem files? Is .crw the correct file extension for that camera?
The crw is the correct file extension.. I tried .jpeg, .tiff and .tif Still nothing... I think your close.. It was something like that that was the fix.. Seems like I had to change something in the files properties..
It is also likely that the recovery wasn't done right. So while the files have the .CRW extension, then contents have been damaged and this is why the programs complain about the file format.
Since you mentioned that you tried Aperture, I'm guessing that you're working on an Apple box. Are the ownership and permissions for the files/folder/disk correct?
Data recovery software will sometimes not be able to determine the original ownership and permissions on the recovered files and directories, and may have set them to something restrictive, by default. (I don't have an Apple computer handy, but as I recall, you can view and change ownership and permissions from the File->GetInfo menu item.) Make sure you're either the owner of the files and the folder they reside in, or that you at least have read/write permission for the file and directory.
Why not just try some data recovery software like rescue pro. It should be able to read the metadata section of the file and put it into the appropriate format. But you will need to copy them to a writable drive. Most data recovery programs won't work directly off the disc.
aborr. I think your on to something.. I think I had to change some permissions or some of the numbers.. That was long ago though and I was using a IBM based PC at the time.. Yes I am on a Mac now and simply unlocking the files do nothing..
I have no idea how to actually change the numbers like you could on the windows system. Nor do I know what to change them to.
flash. I tried a recovery program.. I used a formated SD card. the program found 193 cr2 files and 47 jpeg files but not the problem ones.. Strange... That is a lot of filed recovered from a card I have formated several times since the files it recovered were taken.

Ok so I went back to this idea..
I re formated the card then I took the files and put them on the card.. Then I deleted the files from the card and ran the program again. This tim the recovery found 4 of the 6 files I put on the card.
Of those 4 files I can now open them all 2 look sort of jacked up. But at least I can open them now and see what they are.. The only thing is now which 2 did it not find and with this system I wonder how many will be lost forever... Makes me want to plug in the old HD and try to recover the whole thing myself..
It's hard to debug this kind of problem in a forum thread, but here's a start:
(I'm thinking that at least some of the files are unreadable because of permission problems.)
On an Apple OS X computer, you can check permissions on a file like this:
- select the file
- from the "File" menu, choose "Show"
- choose "Privileges" from the pop-up menu in the "Info" window
If the file shows something other than your user name as the owner, make sure that "Everyone" has at least "Read" access to the file, to the folder it's in, and to the disk.
If the permissions are too restrictive, you need to change them.
note: If you want to change the permissions on a file, and you're not the owner of the file, you need "superuser" (also known as "root" or "admin") privileges to make the changes. It's a little harder to do this on an Apple machine than on a Windows system, so I won't try to detail the steps here. One step at a time.
Hello, if you have lots of corrupted cr2 image file then do not panic!! now it is possible to repair corrupted or damaged cr2 file. To repair you can take help of best and effective cr2 repair tool. It is specially made to repair damaged cr2 images.
Hey guys, There is a effective process has come to be safe from CRW file deletion. if you lost your cr2 files then you do not have to do anything more just start CR2 Recovery process with the help of third party effective tools. with the help of this process you can easily recover your cr2 files in easy way.
