Unexpected CF card failure, sandisk 32 GB, bought last year from sandisk UAE (dubai duty free) so unlikely to be counterfeit, barely used, since I was using mostly 750D that takes SD, started using it 2 months ago along with other cards, so it has been used less than 10-20 times.

Yesterday was a holiday and took plenty of photos with it, everything was fine till I put in the card reader I usually use, the PC recognizes the drive but doesn't recognize the card, other cards work normally on the reader.

IS there an easy  way to retrieve the photos taken ?

Are the other cards smaller in size? If the camera handles the card just fine, the obvious suspect is the card reader, not the card.

The card reader has been working fine for years, it's USB3.0

With the more expensive SanDisk card comes a code for using their RescuePro Software. Maybe that's the way to try, I don't know. You also could try another CF card at the reader to see if that works better. Or change the USB plug to another connector.

Does the camera still recognize the card and read the files? In this case you could use the camera as the card reader and connect it via usb to your PC. No idea if the camera supports this, though.

No camera says card needs formatting

Once again your reply doesn't answer the question. Maybe I don't interpret it correctly.

Looks like the controller is dead. Try a data recovery service if you have them around - but I'm not sure they can replace that part at least to extract the data. I know it can be done with HDDs but I have no idea about memory cards. However, this is better than just chucking it into the recycler as is...

Hi Toni,

 

sorry for the data loss with the card ... but ...

I have to admit, you did something (or better omited it)

you shouldn't do.

 

You used a storagedevice without giving it a one-time full-write-test

as a start. I do that with all my harddrives and with all my flashdevices

(SSD, USB-Sticks, SD-cards and CF-cards) ... I use a testprogram that

fills the device entirely with data and re-reads all files from the device.

Since the data is not just nul-bytes, but a nonrepetitive sequence of

bytes, it cannot be tricket into beliving the malicious device-size of a

fake-device. Only if this one-time full-write and full-read has been

running successfully I use this device for any other purpose. (Upon

failure, I would return the device to the vendor (if bought new)).

 

Unfortunately, cards that are not even recognised on a device-level

can hardly be recovered by simple SW ... I keep my fingers crossed, but

I don't see you getting your images back from this card ... sorry to say so.

 

Rainer

 

PS: Just to make sure you get my point ... executing a test as I usually do

will not generally save me from such card errors ... but such errors will be

less likely ... at least, if the error is not related to a malhandling of the

card (or just bad luck aka static electricity) in the moment the card failed.

For errors due to a failure that is already dormant in a device at the time

you get it from store, the procedure helps ... since most technical devices

follow the "bathtub-curve" regarding the likeliness of a failure ...

a certain amount of errors at the beginning of the lifetime ... a long

period with only few errors and a rising amount of errors at end of life.
