What causes data loss?

Data recovery may become necessary for a wide variety of reasons, but generally the failure can be categorized as resulting from physical damage or logical corruption.

Physical Damage
  • Moisture contact or penetration
  • Exposure to extreme temperatures
  • Variations in humidity
  • Shock or force sustained
  • Defective mechanical or electronic components
  • Spike or surge in power source
  • Degrading read/write heads

Logical Corruption
  • File System formatted
  • Operating System reinstalled
  • Files deleted or recycled
  • Software (ScanDisk, CheckDisk, Defrag)
  • Virus intrusion
  • Broken or corrupted RAID array configuration
What is data recovery?

Data recovery is the process of recovering data from storage media when it cannot be accessed normally. Hard drives are among the most common types of storage media requiring data recovery. However, there are many other forms of electronic, optical, and magnetic storage media that can become damaged or corrupted. Data recovery is generally considered to be the last resort when all other attempts to retrieve the data have been exhausted.

How does data recovery happen?

The data recovery process depends on the type of recovery necessary for your particular situation. We begin with a diagnostic process to determine which solution fits your needs and then you are contacted to discuss your quote.

How long does data recovery take?

We have three data recovery service options:

  • Emergency Service - 48 hour turn around time
  • Priority Service - three to five day turn around time
  • Standard Service – seven to 14 day turn around time
How much does data recovery cost?

Data recovery costs can vary depending on the type of storage media, severity of damage, specialty parts, and turn around time required.

What is the success rate of data recovery?

The good news is, although there is no guarantee that data can be recovered, we have years of success recovering data from all types of media. The success of data recovery depends on the nature of the damage to the storage media. Unfortunately, chances for successful recovery decrease if there is physical damage to a hard drive's platters or magnetic layer. Severe physical failure can cause irreversible damage to any kind of magnetic storage media.

Is there anything I can do to recover my data?

Users inexperienced in data recovery can cause more damage to their storage media when attempting to recover data themselves. If you are in already in a data loss situation, contact us right away to discuss your options for safe data recovery.

What is the data recovery confidentiality policy?

Our Data Recovery Lab is a secure environment. All customer data is kept private and laboratory access is controlled to ensure only appropriate specialists handle sensitive information. Advanced Computers Ltd agrees not to disclose any and all information for data files supplied with, stored in, or removed from the client except to employees or agents of Advanced Computers Ltd subject to confidentiality agreements or as required by law.

Do you recover laptop hard drives?

Yes, laptop hard drive recovery uses the same methods as desktop hard drives.

What types of media can you recover data from?

Listed below are commonly used types of storage media that may require data recovery:

  • Magnetic Drives – used to store data in laptops, desktops, servers, network attached storage, external backup devices, digital video recorders and MP3 players. Media examples: 1.8″, 2.5″, 3.5″ and 5.25″ IDE/SATA Drives, 50-pin, 68-pin, UltraWide SCSI Drives and 0.85″ CompactFlash Type II Micro Drives
  • Magnetic Tapes – Used to backup data in small to medium sized file servers Media examples: AIT, DAT, DLT, Exabyte, LTO, QIC, Travan & VXA Tapes
  • Magnetic Disks – used to temporarily store or transfer small amounts of data. Media examples: 3.5″, 5.25″ Floppy Diskettes, and Jaz, SyQuest and Zip Cartridges
  • Optical Discs – used to store files from several megabytes to several gigabytes in size. Media examples: CDs, DVDs and Minidiscs
  • Flash Cards – used to store photos in digital cameras, music in MP3 players, PDAs and files for many types of applications. Media examples: CompactFlash, Memory Stick, SD, Smart Media and SD cards
Can you recover data if I've had a virus attack?

Most viruses attack files that the computer uses to function normally. A security breach can result in noticeable performance changes, random rebooting, adware, spyware and even missing files. The majority of these issues can be addressed with our Comprehensive Overhaul Service. In the event the virus deletes or corrupts files, we are experienced in repairing this type of damage.

From what operating systems can you recover data?

We recover data from a variety of operating systems. The most common platform in use today is Microsoft Windows. Other widely used operating systems include: OSX, RedHat and FreeBSD.
