External HDD Data Recovery Information
These are some real problems experienced by External HDD hard drives we see in our lab. We are not affiliated in any way with hard drive manufacturers. All the information below is based solely on our experience and we do not make any claims regarding reliability of the specific model. We see mostly failed drives in our lab and therefore we don't have complete statistics.
Data recovery for external USB hard drives usually requires removing internal hard drive, fixing it using specialized equipment and hardware tools to the state when it is possible to image the drive and recover the files from the image afterwards.
Typical symptoms could be messages that USB Device has malfunctioned and therefore cannot be recognized. Sometimes the device itself might be seen but no partitions or volumes could be found. Or partition might be present but user gets an error when trying to access this volume. File system might also be recognized as "unknown", "raw" and be 0 bytes in size. You might also get "The file system structure on the disk is corrupt and unusable. Please run the chkdsk utility" warning in Event viewer... etc.
In case the drive was reformatted or some files were deleted we could also help. Our engineers use special hardware that is capable of reading raw NAND flash chips and reconstructing the original file system on the drive.
