You can scan the devices that recognized by your PC, preview the lost file and add corrupted video files for repairing. But only registered version can recover the lost files and save the repaired video files.
When you access a drive and get the prompt with 'x: is not accessible' or 'You need to format the disk in drive x:', the directory info of your drive might be damaged. In most cases, the data area is probably still intact. You can just run Cisdem Data Recovery and scan the right/lost partition to get your lost data back.
1. Type in keywords combincation into the search box to filter the target files.
2. Type in the file extension into the search box to filter all the files with that associated file type, list them by size and recover the files that with the same size as the lost file.
3. If the files that you've recovered through the above methods cannot be opened, you can go through files under Type> Tagged Extracted folder, Cisdem will recognize the device information for those files and list them under different folders.
4. If method 3 is still not working, please go through the files under File Name Lost folder.
Cisdem Data Recovery is able to recover data from a lost partition, you can just run Cisdem Data Recovery and scan the right lost partition to get the data back. If you are not sure which partition to select, you can scan the whole disk by clicking 'can't find location'.
Cisdem Data Recovery offers data filter and search functions. You can search them by file/folder name or file extension or filter the files by size and type.
We use several different scan methods to ensure a better scan result. One file could be detected by multiple scan methods and each method will create one copy of the file in the scan result, so it is normal more files found than you actually have. You may just try them one by one, and save the copy that can be accessed correctly.
A disk can be formatted in three different ways: Quick, Standard and Low-Level (physical) formatting. Quick formatting just recreates the file directory info and makes the drive space show as empty. But the data area is actually not touched or damaged. You can still recover the lost files with Cisdem Data Recovery.
However, the Low-Level (physical) formatting initializes the entire disk area. All of the data contained in the disk is erased, preventing any future recovery attempts.
A file is saved as 2 parts on the storage device: directory info (which contains file name, time stamp and size info, etc.) and data content. If the files you've recovered from Files with Directory cannot be opened, one possible reason is the currupt directory info. There is still a chance to get the data content through the Files without Directory.
It strongly depends on the capacity of your hard drive and the performance of your computer. As reference,most drive recoveries can be completed in around 10 to 12 hours for a 1-TB healthy hard drive in general conditions.
As long as the lost files haven't been overwritten by new data, you can restore them no matter how long it has been.
The storage structure of the lost files would be altered or damaged by any changes on the drive. If you save the recovered files back to the same drive, the original data structures and data content would be corrupted or overwritten, which causes permanent data loss. So you should prepare another disk to save the files.
Please follow the steps below to troubleshoot the reason that causes this issue:
1. For your reference, the deep scan can be completed in around 10 to 12 hours for a 1-TB healthy hard drive in general conditions. If your scanning time is in this time range, please wait patiently and do not stop the scan during the process.
2. For some reasons, the hard drive is disconnected from the computer, especially for external ones. To fix this issue, please change a new cable and do the recovery again.
3. Your hard drive contains a serious physical error (such as bad sectors, bad tracks). Please use a professional tool to diagnose your hard drive. If the diagnosis shows physical error, you may need assistance from a local data recovery lab.
This error is mainly caused by an unstable connection during the scan or the failure occurred when Cisdem Data Recovery tries to read the sectors on your hard drive. Please follow the steps below to fix it:
1. Safely remove your storage device and reconnect it. Please make sure not to close our program when you try this method.
2. Switch to another USB port or change a new cable.
These files with random file names or folder structures must be found by RAW Recovery, which is much reliable and useful while the file directory info of lost files has been damaged. If you can not find the lost files from the recovered files with correct file names, you can try to check every file with random names to get lost data back.
