Recover data from formatted xd card
Hi,
about 5 or 6 years ago I took loads of photos on my, at the time, relatively new camera.. I stupidly formatted the xd memory card after I got back from my holiday and lost the lot ![]() A friend tried to recover the data at the time with no joy but I wondered, as technology has advanced, if there were any reliable programs or companies that have a high success rate recovering lost data. I've kept the card all these years on the off chance they may be recoverable and actually forgot I still had it until I had a bit of a clean out. No photos were saved to this card after I formatted it thanks in advance for any advice or recommendations! |

Recuva? http://www.piriform.com/recuva
From the CCleaner people. Haven't used it for a while and its not currently installed, but for a formatted card you may have to enable the option "Scan undeleted files" or something like that. Has been about 18 months since I used it so I'm sure it's even better now. Let us know how you get on. |

Thanks for the link.
Just tried it, set it to deep scan, and nothing ![]() it did find a load of 0 byte files that it said were unrecoverable but there were over 700 of these and there was only about 50 photo's on the card so not sure what these were

thanks redtux, I tried that program you suggested but still no joy.
I emailed a company (as prepared to pay if neccessary) and was told that Fuji's have a nasty habit of totally deleting files when formatted and even though they could try (for £10) the chances are they won't be recoverable.

out of interest - if a single pass can zap the data to an unrecoverable state - then why do you supposedly need a multi-pass shredder to fully clean a pc - hard drive?

The file allocation table (as well as the way RAM is used to write data before it goes to the HDD, and other things) is the reason why you should use the safely remove option before yanking a USB drive out of the PC. Its the same with all memory formats, so you SHOULD be able to get files from a memory card, but files have probably overwritten the data on a memory card. |

Completly different type of storage technology. HDDs use magnets and to totally erase the data can take many passes. Flash memory doesn't have the same problem, data can be erased much easier.
Old magnetic hard disks did indeed need several passes, with modern disks only one pass is necessary to make the data unrecoverable. |

Essentially when you delete a file, your hard drive doesn't delete it, more so it tells the HDD's file allocation table (the thing that keeps your hard drives content and structure indexed) that you can now overwrite that portion and use it. The reason you can recover files is that generally your HDD won't use recently written space to use new files straight away, unless there is no other space to use.

I know the "delete" just changes a status indicator in the fiel header - but the shredders that erase the file still execute multiple passes over the data - if the first pass sets every bit to say, 0, why would you need multiple passes. How could anyone recover the previous state of the bit, even after 1 pass.
But, this does not apply to modern hard disks as the much higher data density basically makes it infeasible. |

I must just be lucky then, I buy them on Ebay and have no problem with them.
