Data storage is a simple task these days and getting the storage device is also easy and not much costly. With the introduction of flash memory storage devices like USB Storage drives, SD cards or secure digital memory cards, data transfer process is quite easier. The Secure Digital memory cards are non volatile memory cards which are commonly used in the portable or mobile devices like Digital Cameras, GPS navigation devices, mobile phones and tablet computers. Photographs clicked with cameras, mobile phones or tablets get stored in tablet’s memory. Secure digital that is the SD cards accepts card specifications that define the physical sizes. Mainly sd cards are available in three sizes Micro SD card, Mini SD card and the Standard SD card. These cards are compatible to all the major operating environments and other embedded system.
This device is easy to handle and very small in size. The structure is just like memory chip with strong component integration. Compatibility issues are not that much as it was in earlier storage devices. Data can be easily accessed by connecting them to host devices like personal computers servers etc without any problem. The host machine on which we want to transfer data from sd card must have an host operating system like windows versions. Windows support SDXC memory cards, the versions that support this device are Windows 8, 7, vista, XP, RT, Server 2003 and other that have compatibility with this device. Speed of this flash memory device is very fast and makes the device work reliably.
There are many types of SD cards specified in many ways according to the physical size of these cards they are specified according to their size or appearance. Mainly these devices are available in three sizes these are mini sd card, micro sd card and sd card. The Micro sized SD card is smallest of them all and is named as microSD, microSDHC, microSDXC.
Speed of the card depends on several factors like frequency of software errors that the user retries to make them successful. Fact that the writing of data requires user to erase previous data and provide sufficient storage space for that operation, make the device run slower. File fragmentation is another factor that effects speed of flash memory devices. File fragmentation of flash memory implies to splitting up into non contiguous fragments. One factor that affects the quality is the manufacturer tag on body. Some major distributers use good quality equipments, that adds durability to flash memory and that is why allows frequent data transfer but some of the distributers provide with very degraded material integration that their functioning is prone to errors and faults. Flash memory devices like SD cards are widely used in electronic media because of their large storage capacity and a very small size. These are not much costly that is why can be replaced easily without any major cause of expense.
Data transfer rate depends upon the speed of flash memory storage device and host computer operating system. Host computer operating systems are many in market like Apple Mac os, Linux and Windows. These are major vendors of host os but Windows is widely used by users of every age group. Because of its very interactive user interface, accessing of files and transferring data files from external to internal memory is very efficient and reliable. NTFS and FAT file system is supported by Windows system. But this file system is now not in much use but still window vista version of windows have the NTFS file system. In earlier versions of windows the FAT file system was used but now with up gradation of system they can be converted into the NTFS format. This format was introduced by Win NT OS and with ACL based permission control it was allowed to use.
Sometimes while transferring data due to some mishandling or abnormal behavior of device the flash memory gets cleaned up without any notification. It is being difficult to look for that lost data on the small screen of digital-device. We can look for them in the windows environment. Connect the flash memory device to the computer using any medium like with USB drive or via Bluetooth or WAN, then look for the files in the USB drive you see in the drive list. Open the device and look for the SD card, if the files are not there then look for them in recycle bin. See if the files are there if they are found; see if they can be recovered. Try to recover them in the disk from recycle bin. In case the files are not present either in the disk or in recycle bin, then try the finder option in the start menu.
If still you are unable to find the lost files then there is only one option to get them back. That is to use data recovery software. But trusting any of them is not a smart choice, because while retrieving erased pictures from camera, if the software you are using contains malware code, they can lead to malfunctioning of your camera application software.
If these types of applications are used directly to recover lost photographs they can cause bad effect on picture quality that file and even it can delete it permanently from disk. Trustworthy applications like the "321Soft Flash Memory Recovery for Windows" should be used for optimum output. Download this software and install it on the Windows system. Now after the successful installation of the software makes sure about some important things that must be satisfied before starting recovering data. Those important points are: First of all don't try to store any other data on that disk from which you want to recover data. Doing this may cause permanent deletion of data from that disk or it will be impossible to recover it again.
Secondly make storage space to store recovered data in the personal computer disk. This must be pre scheduled before launching the application because if sufficient space is not there, in the disk for storing the recovered data then it will quit the operation in between, which may lead to permanent deletion.
The third thing that should be kept in mind maintains a sufficient battery backup for computer system to for safe and error free recovery.
After all these are checked and are satisfying then launch recovery application, Insert the flash memory device through the USB slot Or the SD card slot in the computer system.
Make selections of the file types you want to recover from the flash memory and the manufacturer name of the device you are using to store data in that flash memory device.
After making these selections on the wizard screen now select the scenarios. There are three scenarios available in on this application and these are deleted, lost volumes and formatted data. Select the appropriate one and click on continue for further operation.
Now provide the storage path for the file where you want to store that files on the computer disk and click to continue.
After the operation is completed, file in the thumbnail format will be displayed on application wizard. You can directly view and can transfer it to any other device. The actual quality picture is being recovered by using 321Soft flash memory recovery for windows.
