More knowledge about external hard drive

Below are some possible reasons for external hard disk error:

  • External disk infected with virus, spyware or Trojan, etc.
  • External hard disk has bad sectors, which disables you to access files on the disk.
  • External disk is damaged because of unexpected system shutdown, improper operation or application failure.

External hard disk is different from hard disk because it works as an external device to store or transfer data. You don’t need to install external hard disk to your computer but you only need to connect it to your computer through a USB cable to write or transfer a large amount of data, so people consider external hard disk as a convenient and large device for data storage and transferring. Along with more and more people like to use external hard disk due to its convenience and large capacities, they also find an unavoidable problem on external hard disk – data loss.

1. External Drive Format or Deleted File Recovery Attention:
After formatting an external hard disk or deleting files from the external disk, the files will be erased from partition table and the external disk space will become available. In order to recover all lost files due to formatting or deleting, do not put new data on the disk where data got lost.

2.External Hard Disk RAW Recovery Attention:
When your external hard disk is not accessible due to RAW file system, bad sectors on the disk or other reasons, you may want to try anything you can do to improve the current situation. However, anything you try to improve the situation might make the situation even worse. For instance, you may want to format your disk to change its file system from RAW to NTFS or FAT32, but what is worse, all data is lost after formatting. In order to prevent you from running into such a terrible situation, we advise you to get back lost data first before you can repair the problem on your external hard disk.
