Was shooting on a Transcend card... (I'm guessing thats where the problem is) and I get a message "card cannot be accessed..."

So I leave the flash to one side, and figure I will transfer it onto my PC with some kind of data recovery program.

I've used:
badcopy
Stellar Phoenix Photo Recovery
EASEUS Data recovery

-- no joy from any of these programs.

Windows wants to format the disk also.

Am I doomed?... I really hope not!

Thanks,

Tom

I am trying to use photo rescue - but have gone into expert mode.

One strange thing, is that if the software can detect the drive, it seems to think it is a 32mb card (and not a 16gb one!)

I have the 16gb 400x transcend card - does anyone know what cluster size this might be?

Thanks,

Tom

Can't offer any direct help but on the occasions I've had to rescue from a card I've had to try many different programs - there are many, many free ones but you have to choose carefully if you use Google to find them - many offer free programs only to charge you to unlock them to be able to restore files. My favourite at the moment is Drive Rescue (free but discontinued and hard to find!) or PC Inspector File Recovery (also free) - both worked for me before. Recuva from the guys that make CCleaner is also supposed to be good.

PhotoRescue, Drive Rescue and PC Inspector dont seem to help at all.

Recuva says "unable to read boot sector".

If I were to do a quick format of the card (Windows cant currently read the card and wants me to format it) do you think I still may be able to recover the files?

Thanks,

Tom

Can't say, but it looks as if you've tried everything else so you have nothing more to lose by trying unless the images are important enough to use a recovery specialist (not cheap!).

There are companies which will recover data from horrendously damaged drives and cards, but they charge lots.

Get my test cards document, and cards for 625, 525, 720 and 1080. Thanks to Gavin Gration for hosting them.

What camera was the card in and what format are the images normally?

Here is what I just posted in another thread on a similar subject:

I lost everything, half-way through a shoot earlier this year. My EX3 just deleted my card (16GB Transcend SDHC) when I switched from playback to camera mode, having just reviewed the last shot with my client. Everything gone and the card empty after a load of footage captured!!!

Anyway, I went to LC Technology, the company that does SanDisk's data recovery app, and dealt with a guy called Ken Carter. They were brilliant and managed to salvage enough for me complete the work and leave a very chuffed client (they paid for the recovery too - about £130). My case was particularly complex as Sony are not helpful to the data recovery people with deconstructing the EXCAM codec, so to get anything back was a bonus.

If anything is recoverable, they will get it for you. They also provide free trial downloads of their software, so try that first, even if the card is not showing up on your desktop, the software might be able to find it.

Let us know how you get on. D

I was shooting video on a canon 7D.

I think I may have to pay for the recovery as I really need the footage... bum.

Is this likely to be the media I have used? I did open the compact flash door before turning off the camera - could that have done it?

Thanks for everyones help,

Tom

Do try the LC Technology free trial. The software is cheap and does seem to work better than anything else I have tried. Failing that, give them a call and get them to get everything for you - worked for me.

I suspect that my error was caused by switching camera modes too quickly and so think you may be right about yours being caused by opening the door to early. Very sensitive things these flash cards! D

Yep, don't ever pull the card out or disturb it in any way while it's recording. The final thing the software does when recording, is to update the boot sector with info about the latest recording. If you don't let it finish that, then chaos ensues.

A post I put in the IOV may help

An update on this, i too have had the dread files missing on the SCHC card (the card was OK) some footage was there but footage shot earlier in the day was not there any more and only noticed when I got home. the camera gave no indication of any problem and all the indicators were showing the correct readings, TC & elapsed, remaining.
After a long search of many useless programs claiming to find and recover mp4 files, I found the one below found the LOST folders and files and managed extract them all. The software would not see the correct file structure with the files, but I just dragged the mp4 files into the correct folder. Everything seems to be up and running now.
The free one also saw the LOST file structure but would not recovery the mp4 file for me, it managed mts and other documents etc. OK

(free trial with option to recover one file a day to check it works)

Free but does not always recover correctly)

Tom, only just seen your post, did you get this sorted?

I use calumet's recovery software and have recovered quite a few folk's data when they were stuck.

If I can help, glad to.

I had a 16GB SD card with a failed memory controller (I think) on a Dane-Elec sourced card from the 7dayshop, it's costing me £240 incl. VAT to have the pictures, video recovered by http://www.datatrack-labs.co.uk/ on the cheapest no hurry option.

I'll be glad to see my missing pictures again, however I am not happy that a 7 month old card can fail in the camera without any misuse.

My advice is not to leave pictures/video on the card for long, I could have transferred my pictures to the laptop every night and only lost one days data, not a high priority when on one's hols.

I used my 2GB card for the rest of my hols and I had plenty of room, I know it would have saved me a bundle if that card had failed as you are charged on size for data recovery.

Please Note:
I had tried all software options before going for data recovery

I finally have my pictures back , Datatrack Labs Ltd finally retrieved 99% of my pictures after using two different processes and I'm £240 lighter (For the very slow option)

We see all this talk about cheap memory cards : http://forums.dvdoctor.net/showthread.php?p=389760#post389760

My concern is not the cheapness of the cards (Mine was under £15), will any of the firms pay for data retrieval if their card goes wrong from a hardware fault?

If I moved into SD cards for video this could be an expensive nightmare

Bigger cards cost more money to retrieve + fast recovery can go into £1000's

Tom, I have found datarescue pc to be pretty impressive. I think their demo version will allow to see what it could recover without forking out for it first. Is was $100 or something though.

Re: Compact flash corrupt - anyone know how to recover?
Now this is probably a silly question to ask and I'm sure it would be one of the first things you will have checked, but I'm going to ask it anyway.
 
Has the wee tab on the side of the card been pressed in and de-activated it ?
 
Cheers

Re: Compact flash corrupt - anyone know how to recover?
A lot of the paid for software seems to be based on some free stuff (contributions invited) such as TestDisk and PhotoRec, which is then wrapped up in an easier to use / fancy front end. To quote from the author's own text file "TestDisk and PhotoRec are written and maintained by Christophe GRENIER <grenier@cgsecurity.org>. Try doing a search on this site - it may save you a lot of money. I tried it on a 16GB SDHC card, and one problem was the volume of data recovered, including masses of video files which had been deleted from long ago. Another was the naming of the files recovered, so there could be a lot of work in looking at the data prior to deciding what you want to keep. It won't cost you anything, and you still have the card to try something alse if you are not satisfied.
