ADMA (direct access to the Advanced memory) the control to handle communication between your computer and SD (secure digital), allows this mechanism for transfer of data quickly and easily. However, in some cases, this parameter will damage the memory card and lead to a situation of critical data is lost. In such situations, it must be a solution to recover data from SD card to find valuable information on the back.
Consider the following scenario.
You have a SD card, which is formatted with the NTFS file system, you can use the transfer of data between computers running Microsoft Windows 7 and the memory card ADMA. However, in the transmission of data by using this method. The logical structure of the card and the card may be damaged. In addition, unexpected problems may occur when you try to use a memory card is corrupted or data.
Reasons for a problem.
The process of transfer of sdbus.sys from the tip of the direct memory access. Sys (security is control bus, digital dashboard). Convert a structure of metadata DMA of the operating system Windows 7, a data structure of metadata for ADMA ADMA and SD card data DMA descriptor called buffered tables and the length of the metadata descriptor table data structures.
The maximum size of the field length is 64 kilobytes (KB) and 16-bit values is, however, if the process of converting the data on the hard disk on the sdbus.sys. checks the size of the buffer table details of your system, Windows 7, as well as for digital control bus, sdbus.sys tables can describe invalid data length in the SYS DD drive. for example, you can data length is greater than 0xFFFF in this scenario. Input/output error. The behaviour of all these situations, the loss of data, that of violence.
How to resolve the problem.
Was to avoid such situations and the need for data recovery, card SD, Microsoft updated to correct the corruption of the maps of memory in Windows 7, but if your data are lost. You need the last restoration
In this case step implemented being updated or is not available on all cards SD, data recovery software is necessary, the application scans the whole SD card which systematically scans photos and high-quality uses, the missingmusic and the video are divided. Application file recover SD card contains a self-describing interface easier to use read – only and cannot be destroyed, these applications are completely safe to use.
Stellar Phoenix photo recovery (Windows) is the application of the ceiling on successful recovery images disappear. The software works well with Microsoft Windows 7, Vista, XP, 2000 and NT supports all important cameras such as Nikon, Canon, Kodak, Sony, Fuji and Olympus.
