We have a self assesment tool which has been developed to give you data recovery advice and to enable you get to a free quote. We do advise reading about the different types of data loss below, but if you prefer not to please click here to go straight to our self assessment data recovery tool.
All hard drives fail
Like most things, hard drives have a lifespan and nobody knows exactly how long each drive will last so it is always important to keep a backup of important data. The most common times for hard drives to fail is either at the beginning or later on in their lifespan, typically over 3 years.
A hard drive can fail near the beginning of its life due to manufacturing defects. This may be because of a bearings issue or a "head crash" and the hard drive will not be recognised by your computer. While many of these issues have been reduced by strict quality control and testing methods, from time to time a large number of users may experience manufacturing defect issues.
Older hard drives have a higher failure rate, as you would expect. A hard drive may gradually start to fail and you will start noticing more errors or crashes, or even just a slow down of your computer. A hard drive may also completely die. You may get errors such as "No Operating System Found" when you power on your computer.
Failing hard disk symptoms
A failing hard disk may start to exhibit these symptoms. The quicker you respond to the symptoms and protect your data the less likely you are to go through a data loss incident.
|Symptom||Possible cause||Data protection steps|
Computer crashes frequently or when under heavy use
Computer start-up takes an excessively long time
Data files are missing
File explorer takes a long time to display the contents of a folder
Hard disk drive diagnostic shows many SMART errors
Important: If you are unable to perform an immediate backup shutdown your computer and bring it straight to us. Attempts to extract the data without professional data recovery services may lead to irretrievable data.
Tips to protect your data
As always, prevention is better than cure so we have some handy tips to protect your data
Use regular backups
Back up data at least once a week with other reliable storage devices, always verifying that the correct data is backed up.
Use an uninterruptible power supply (UPS)
In the event of a surge of electricity or lightning strike, a surge protected UPS protects the computer from becoming damaged. In addition, it has a battery backup that keeps the computer running, allowing you to save the data and avoid any loss. Alternatively, a surge protector is also a good investment.
Prevent your PC from overheating
Regularly check for dust in and around your computer. Always make sure your computer fans are unobstructed.
Run a virus scan regularly and keep it up to date
Computer viruses are one of the worst enemies to data protection. Run a weekly scan and always make sure your anti-virus software is up to date.
Check the room temperature
Extreme heat can result in the premature failure of hard drives, while low humidity combined with dust in drought conditions can promote static electricity issues with electrical components. Adjust temperature and humidity control systems accordingly during changing weather conditions.
Be aware of strange noises
In the event of strange noises or grinding sounds, turn off the computer immediately and call us. Further operation may damage their hard drive beyond repair.
Invest in air conditioning
If you are dealing with larger servers, make sure that they have adequate air conditioning. Increases in computer processor speed have resulted in more power requirements, which in turn require better cooling, especially during the summer months.
In the event of data loss, simply contact us to discuss the solutions available.
Tips for a successful data recovery
You should never assume your data is unrecoverable. Below we have listed some tips to help prevent further data loss.
If you hear strange noises from your hard drive you may have phyiscal damage
- Do not shake, disassemble or attempt to clean any hard drive or server that has been damaged – improper handling can jeopardise the data recovery process
- Never attempt to operate any visibly damaged devices
- Turn off computer immediately – further operation may damage data beyond repair
- Do not use recovery software since it may destroy what was otherwise recoverable data
- Do not place a fire-damaged drive in refrigerator to cool media and do not try to remove hard drive – ship the entire computer for recovery
- Never attempt to dry water damaged media by exposing it to heat. Instead, place the media in a container that will keep it damp before shipping
- Users may see messages such as "No Operating System found", "Corrupt Volume" or may simply be missing files and folders
- Shut the computer down immediately. The longer a damaged hard drive is left running, the more data that can be irretrievably lost
- Do not run FSCK or CHKDSK file system repair tools on a virtual disk unless a good backup has been validated by restoring it to a different volume
- Do not plug in or attempt to power up the damaged drive
- Place the drive in a sealed anti-static/plastic bag and keep the media damp. Do not try to clean, dry or expose water-logged drives or other media to heat – such as that from a hairdryer
- Restore backups to a different volume; this ensures that all important files are good on the backup before possibly overwriting data on the active volume
- If there is a RAID problem, test the backup by restoring it to a different location or image each drive from the RAID before attempting a rebuild
- Do not create any new files on the disk needing recovery or continue to run virtual machines until the important data is recovered
