![]() Original CFC cards were based around Intels NOR, but they have now become NAND based. These devices are susceptible to physical damage however due to their delicate design and casing.Ī Compact Flash Card is a common form of portable storage from digital camera but it is now being super ceded by either the SD card or the xD Card which are smaller in size and are now outstripping the Compact Flash card is storage capacity. The lack of a controller meant that Wear Levelling was not possible and this caused incidence of failure. They lacked the controller chip which was a feature of the latter produced SD and xD card. They consisted of a Flash NAND chip embedded into a very thin and lightweight plastic card. ![]() The SmartMedia card is now no longer manufactured but was a popular storage option for digital cameras and digital audio players. Accidental or Deliberate deletion of images from the card.The device storage capacity shows up as an incorrect size e.g.Images or Device Data does not show up or accessible.These devices are again less susceptible to physical damage due to a more rigid casing but if these cards snap in two it is impossible to recover any images from them. Their capacities are limited to 8GB although presently their capacity on the general market appears to be no larger than 2GB. They are increasingly popular due to their compact size. The device appears completely dead and does not show up when attached to the camera or card readerĪn xD (extreme Digital) Card is a card made exclusively for use in Digital Camera and Voice Recorders and is designed and produced The Toshiba Corporation and Samsung Electronics for Olympus and FujiFilm.Recovery of images from devices that have been formatted.Due to their small size they are extremely brittle and should be handled with care. Variants of this card include the RS-MMC (Reduced size MMC) and the Dual Voltage (DV-MMC) card.ĭue to it's small size (approx the size of a postage stamp) these cards were extremely popular but were also prone to suffer from damage - typically being bent or snapped when trying to remove from a reader or camera. Their main use since the launch has been for the storage and transfers of digital photos from Camera to PC. The MultiMedia card was launched in 1997 and is a NAND based flash memory type.

If your data has been corrupted, erased, damaged or if you have accidentally deleted your digital images and pictures we can help. Deleted Files or formatted SD devices are normally fully recoverable.Bent, snapped or physically damaged devices can normally be fully recovered.The SD does not show up at all when inserted into a card reader, digital camera or computer.SD Card Requests to be formatted when attempts are made to access it from within your operating system.SD cards are also susceptible to physical damage due to their lightweight design and casing. The card appears either full or empty when showing the device properties."Card requires formatting" message appears when the card is inserted in a reader."Device not recognised" message when the card is inserted in a reader."I/O card error" message on your camera.Very often indicators that this type of failure has happened occur when you get the following: It is worth noting that all Flash Media are designed to be able to withstand several thousands and (potentially) hundreds of thousands read / write cycles before the device eventually permanently fails. The controllers writes data to the Flash NAND via the use of Wear Levelling Technology which allocates data to specific areas of the device, ensuring it is evenly spread to ensure that specific areas of the chip to not receive continuous data writing thus reducing it's life span. Typically the internal circuit of the SD card will contain two chips, the Flash NAND (on the left of the image) and the controller (smaller chip). With ever increasing storage capacities the SD card is an ideal option to take on holiday and fill with several hundred photos. Unfortunately, errors often occur, these include:Īn SD (Secure Digital) Card is possibly the most popular form of digital photo storage and can be found most commonly in your digital camera or camcorder as an external storage option or photo transfer utility. With ever increasing memory use by digital cameras, mobile phones, etc, tiny storage devices are increasingly popular. We also provide services from other digital picture storage media such as xD Cards and Compact Flash Cards. R3 Data Recovery is a digital photo recovery service provider who specialise in the recovery of digital pictures from failed and damaged SD memory cards. SD Memory Card & Digital Photo Data Recovery
