Data Recovery Services on Hard Drives, RAID, Samsung Galaxy, Iphone, Ipad, SSD

Deadhardrive® is a French company, based in Shanghai and Hong Kong, expert in data recovery services and forensic. We work in a class 100 Clean room.

RAID, NAS and SAN Data Recovery Services

We provide extensive RAID recovery services. The safe and proper way is to image all the drives of the RAID array first, then work on those images to rebuilt the data. We often need to repair one or more drive from electronic or mechanical failure first then image afterwards.

In theory, we should not have to perform raid 5 data recovery, since this type of RAID can work in degraded mode until your replace the bad drive, then everything is back to normal once the RAID 5 rebuilt itself.

The most common mistake and RAID 5 is when a good disk is replaced instead of the bad one. An immediate failure occurs since most RAID can’t work with 2 disks basically not working. The same problem occurs if the user specify a wrong number of disk while rebulding the failed RAID. This happens often due to the use of a hot spare which is not in theory part of the raid itself.

On the opposite, RAID 0 recovery is common, since this type of RAID offers not tolerance to failure. If any of the drive crash or fail, then your data are gone. We perform a lot of raid recovery on RAID 0.

There is one case, where we can’t recover any data though. If a RAID is reinitiliazed (which takes hours), all data will be lost. It will basically write 0 over the entire disks. There will be no data left to be recovered.


Hard Drive Data Recovery Services

We mainly work and provide services on physically or electronically damaged hard drives. Most of logical recoveries can be done with the proper hard disk recovery software and donnot requite help from a professional.

Here is a list of typical symptoms or causes of a hard drive crash or failure:

Your hard drive makes a clicking noise, this is called the click of death and can be a simple firmware issue as well as the result of a head crash. Follow the link for all the info about the click of death.

You dropped your external hard drive. Well, most of time this is not a good news. Chances that the device is physically damaged are high. Your hard drive might not be detected by your OS anymore.

A crashed or dead hard drive, needs most of time to go throught repair first before being able to extract anything out of it. In some cases the drive will only work a short period of time. If we speak about hard drive repair, we speak about PCB swaping or fixing, head swap in a clean room or platter removal if the engine is dead.


Iphone and Ipad Data Recovery Services (Chip Off)

We perform Chip Off recovery for any dead Iphone or Ipad

Whether you have dropped your iphone in the water or if it isn’t working at all, we are able to fix it in order to recover data out of it. Iphone recovery services do not require a clean room, but some deeper knowledge about flash memory and encryption.

Once we fixed your device, we can recover deleted photos out of your iphone, sms or videos, if they haven’t been overwritten by other data.

How to retrieve deleted text messages, is also a very common question we got all the time. Text messages are stored in a Sqlite database that we can work on. This is not the case for photos or videos, which makes the recovery more likely for text messages in fact.


Samsung Galaxy and Galaxy Tab Data Recovery Services

As for Iphone and Ipad, we perform Chip Off Recovery on Samsung Galaxy and Tab devices.


Solid State Drive (SSD) Data Recovery Services

We perform chip off and rebuilding the array when your SSD is out of order. This is pretty much like a RAID Data recovery.


SD Memory Card Data Recovery Services

SD memory cards are flash drives as well, but works in a different way that Iphone or smartphone. If you just deleted some photos or documents, a simple software like Recuva or Photorec, both free, will be enough to get your data back. If your SD card has been twisted or is broken and thus not detected by any OS, then you migh need a pro for SD memory card recovery.
