1. Supported file formats for recovery


2.Supported data sources or storage devices for recovery

Simplified Chinese Windows 7 systems 32 bits and 64 bits
Simplified Chinese Windows 10 systems 32 bits and 64 bits
Traditional Chinese Windows 10 systems 64 bits
English Windows 10 systems 64 bits
Korean Windows 10 systems 64 bits
Chinese Windows 8.1 systems 32 bits and 64 bits
Chinese Windows 8 systems 64 bits
Chinese Windows Vista systems 32 bits
Does not support Chinese Windows XP systems


3.Supported operating systems

USB flash drives
SD cards
SSD drives with Trim commands disabled
(Since the Trim commands will periodically perform a recycle action to the hard drive, this will cause the lost data to be unrecoverable by the recovery process)
Cameras, surveillance cameras, drones, and dashcams


Some products such as cameras, surveillance cameras, drones, and dashcams will process the generated data in ways that have not been publicized, so full recovery by the recovery process cannot be guaranteed. The following is a list of devices that have been tested and passed:


4.Supported file systems



5.Supported situations for recovery

Accidental deletion
Accidental formatting
Partition lost
File system header corrupted (FAT, $MFT)


6.Unsupported situations for recovery

Full formatting (Low-level formatting actions to the system)
Overwritten data and files are not fully recoverable
SSD drives with Trim commands enabled
Encrypted drives


Can my data be fully recovered?

We cannot guarantee one hundred percent recovery of your data, but in most cases the data can be recovered normally using our software.


I have recovered the file, but I am unable to open it?

When this situation occurs, it could be due to the following reasons:
(1)The file has been corrupted
After a file has been deleted, it can be corrupted or overwritten by another file. Defragmentation, virus attacks or hacker activity will cause the file to be corrupted.
(2)Fragmented files
Some large files are stored in separate sectors on the hard drive, since they are too large be allocated to continuous sectors of the storage space. When the data from one or more sectors has been deleted, recovery is very difficult. Even if the initial address is accessible, the address information of the erased data is often lost.


How long does data recovery normally take?

It depends on the size of the storage space and the size of the data. The larger the data, the longer it will take; contrariwise, the smaller the data is, the shorter it will take.



Before using the Lexar Recovery Tool software, the success rate of recovering your files greatly depends on how the storage device is used, and whether there were any new written data after the accidental deletion.


Do not continue to work on the storage device with the lost data on it!

(1) You should not continue to use the drive which contains the accidentally deleted files.
(2) Do not use operations such as copy, cut, or paste on the drive.
(3) The more actions that have been done on the drive, the lower the success rate of recovery.
(4) If recovery of lost data is needed, please do not defrag the drive or execute any tool that can possibly do further damage to the drive. Otherwise, it could erase the data of the file on the drive that you want to recover.
