Here is a list of typical symptoms or causes of a hard drive crash
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.
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.
Why is the hard drive making this clicking noise?
Whatever you do, you will need to repair the hard drive first.
The System Area cannot be read. You can have 4 main reasons (and a possible combination of them) for this to happen:
– Heads are damaged
– Preamplificator is dead
– SA corrupted or scratched
– Firmware on the PCB
We can get data back from any type of Apple products:
– Imac, Mack book, Mac book Air
– Iphone or Ipad
– OSX Servers
We use an IOS 5 class 100 clean room
in order to repair hard drives
when then require to be opened:
– External Hard Drives
– Mac or Apple Drives
– Server (RAID or NAS or SAN)
– Computer Drives (Internal)
– Helium Drives
– Fusion Drives (Apple)
What type of failure requires a drive to be opened?
This is typically the case, after:
– A head crash (Fallen drive for example)
– A dead engine or spindle
– A Dead Preamplificator
– A Mix of those…
In a few words, a class 100 clean room, provides a dust free environment and requires the technician to be suited up with gloves in order to open hard disk safely.
Helium drives are big capacity hard drives, from 3 to 10Tb. We can get your file back on those too.
