For a website or a server, there are systems in place to prevent data loss. In instances where failures do happen, there are also backup systems in place to recover the lost data.

Even if data loss is total, there are still ways to recover the information from a failed hard disk. While there’s no guarantee that all the files will be recovered completely, the odds still good enough to give it a try.

The following are steps you should take in trying to recover lost data:


  1. Shut down the computer.

Shutting down the computer will stop the hard disk from spinning. Any further disk movement may cause further damage to the drive and its contents.

  1. Replace the hard disk.

The faster that the hard disk is replaced, the sooner you can have the website or server running. Most servers have RAID systems in place and replacing the drive allows the computer to automatically recover the lost data. If the computer does not have a RAID setup, follow the succeeding steps to recover your files.

  1. Create a disk image.

Connect the hard disk to a computer with enough free space to copy the whole disk. Run a disk image program. This will copy all the sectors of the drive into a single image file. All succeeding attempts to recover files will make use of the disk image.

  1. Recover data from the disk image.

To recover the files, mount the disk image file on the computer, and run a file recovery program. The program will attempt to read the files from the raw data on the drive sectors. It will not use the file allocation table or the file system on the drive. The recovered files will have random names, except for the extensions which designate the kind of file recovered. The recovered files will include some which have already been deleted, duplicate files, and temporary files.


  1. Copy and sort the recovered image to the replacement hard disk.

After the files have been copied to the replacement disk, you can start sorting through the files. You will need to open each file, and determine whether this is a complete document, or only a partial copy. You will also need to sort the files according to whether they are current and usable, archive, or if these are older copies and can be deleted.

Depending on the size of the hard disk, the volume of data on the drive, and the extent of damage, data recovery in Singapore will take some time and a lot of patience. Considering the amount of time this will entail, it would be a lot better to have systems in place for a quick recovery of any lost data.
