Apple Mac Data Recovery.
The dis-assembly and removal of hard disk drives installed in Mac Computers requires specialist tooling and procedures. Here at Datlabs we have fully trained staff able to deal with failed hard drive situations involving Apple Mac computers and storage devices including faults such as read/write head failure, bad sectors and electronic problems. All our technicians are users of Apple devices and can therefore help with problems ranging from the straightforward to the full complexities of the HFS+ Journaled File System, which can be problematic and is particularly susceptible to corruption.
Datlabs Dedicated Data Recovery Process.
Our process begins as soon as your get in touch with our team, we’ll be on hand to advise you and suggest possible fixes and will ask the detailed questions to help get your data recovery case underway. Unlike most PC’s, safely extracting hard drives from Apple devices can be difficult for the untrained – especially the common iMac system, which requires the screen to be carefully removed. Having been a leading data recovery company for the last ten years we can offer an unrivalled service to customers looking for Apple data recovery, this includes collection of the entire device with enhanced compensation to cover its value. Upon arrival our Mac specialist’s will carefully extract the failed hard drive from the device and for an additional cost install a brand new hard drive to get you back up and running again. Once we have access to the hard drive we will undertake the diagnostic process using industry leading hardware to identify the problem(s) so we can provide customers with a detailed, no obligation quotation.
Apple Mac Hard Drive Typical Failures.
Like all hard drives, those from Apple devices are prone to failures arising from misuse, wear and tear or just plain bad luck. However the filesystem used by Apple (HFS+) can cause unique problems such as those detailed below, if you are encountering any of these issues please give us a call.
Apple Mac Bad Sectors (Media Degradation).
Bad Sectors is the leading failure type we encounter with not only Apple devices but all hard drives. However the HFS+ file system utilised by Apple computers and devices certainly increases the likelihood of such a problem due to the high IO of the OS. The journaled file system, though very fast due to how it stores the data, increases the number of read and write cycles asked of the drive. This increase in the intensity of the data requests subjects the hard drive to a higher degree of read/write strain over time which can result in a significant increase in the amount and severity of bad sectors problems occurring on Apple devices.
Typical symptoms of this failure are a sluggish machine, lock-ups during operation and failure to boot into the operating system (OS) . Unfortunately no software can fix this problem and dedicated hardware is required in order to produce the best possible image or clone of the drive so that a recovery of the data can be conducted from the clone.
If you are experience such symptoms and still have access to your data we encourage you to make a backup as soon as possible, if however data access is no longer possible due to severe bad sector issues, please give our team a call for a free, no obligation diagnosis.
Apple Mac File or File system Corruption.
Here at Datlabs we refer to this as logical failure, the hard drive in these cases is not itself faulty however something has corrupted the file system or files and as a result the user is unable to access their data. Most computer users will at some time have experienced a Windows PC asking for a hard drive to be formatted, this is usually because the OS cannot find a valid file system to mount the drive or the drive is blank. Each hard drive has specific sectors that the system uses to identify the file system type, size, start location and so on. If however this information either becomes corrupt or inaccessible, your computer will not be able to mount the device and complete the boot process needed to provide access to the data. This process is similar with Apple devices, and if the important file system data becomes corrupted the system will unable to mount and access the data.
If you are confronted with the error message ‘A volume failed to mount ‘or you simply see a folder icon when you turn on the machine, you may well be experiencing a logical failure.
Apple Mac Hard Drive Clicking.
Physical failure can often result from a hard drive being subjected to a knock, drop or other shock, but can also happen due to normal wear and tear or just plain bad luck. Here at Datlabs we see many external and internal hard drives with physical/mechanical failures, the percentage only being beaten by the bad sector issues described earlier. Physical/Mechanical failures usually relate to a failure of the delicate internal read/write head assembly (HSA) which is responsible for writing, reading and amplifying your data to and from the magnetic platter surface.
Physical failures are more common in portable devices such as the MacBook and MacBook Pro, but can occur with any hard drive. Typical symptoms of such a failure are unusual noises such as clicking, knocking or beeping emitting from the hard drive. These noises occur when the hard drive is repeatedly attempting to read a vital area of the hard drive but a failure of one or more of the read/write heads prevents it from being able to do so.
Unfortunately recoveries from mechanical failures require the most complex and intricate processes and need to be conducted in a clean air and static safe environment by trained and more importantly experienced technicians. No software can fix issues of this kind and if you are confronted by such a failure we highly recommend you power off the device and give our specialist team a call.
Restoring Deleted Data on Apple MAC computers.
Usually arising from accidental or unintended user action, deleted data refers to when data has been deleted from the drive or the drive has been reformatted or repartitioned. Here a Datlabs we employ industry leading software and other skilled techniques to recover data from such an incident. However if the desired files have been subsequently overwritten with newer data this would unfortunately render them unrecoverable. To avoid such an outcome we highly recommend that as soon as such an incident occurs, the device is powered down. Operating System processes are constantly making changes and could potentially be overwriting the data required. If you have experienced such a problem then please give us a call, even if it is simply for our free advice which could just avoid you losing your valuable data.
Mac Hard Drive Firmware Failure.
Although these issues are becoming less common, they can still arise with all types of hard drives. Electronic failures relate to faults with the hard drive’s printed circuit board (PCB), normally located on the underside of the drive. This board is tasked with managing all the data flows in and out of the drive and with communicating with the host computer, but another of its vital functions is to control and distribute the electrical power the drive needs. Any shorts, power surges or sudden power interruptions can cause damage to vital components and prevent power being distributed, preventing normal operation and access to the stored data. Typical symptoms of such a failure are an apparently ‘dead’ hard drive that makes no noise, is not detected by the host computer and displays no signs of normal operation at all.
Hard drive firmware relates to the drive’s unique built-in operating software that the drive uses to control all its internal operations, data flows and interactions with the host computer. This is a very complex and specialist topic, but it is vital that this coding remains accessible, correct and undamaged. Loss of access to firmware or firmware corruption can cause various symptoms, including unusual drive model, serial number and capacity information being displayed, partial or total loss of access to data or the drive not being recognised at all. Unfortunately without specialist equipment, diagnosis of firmware problems is very difficult, and rectifying such problems is not possible. Fortunately here a Datlabs we have the necessary equipment, skills and resources.
