External hard drives are mainly used for two purposes i.e. back up and easy data transfer. You can plug external hard drives normally via FireWire cables. When you connect external hard drive, Windows Operating system identifies it as another hard drive. External hard drives works like internal hard drive only. But, the main difference is external hard drives are located outside the computer. You can also divide external hard drive into different logical sections and the data that is stored on external hard drive is organized and managed by file system. Windows Operating system supports two different type of file system i.e. FAT (File Allocation Table) and NTFS (New Technology File System) and it has different partition tools like FDISK and Disk Management utility. You can also use Partition Magic partitioning tool, which allows you to re-size the partition without losing stored data. Generally, while re-partitioning your hard drive using Disk Management utility, you may encounter partitioning errors, which may not allow you to access data from those partitions of external hard drive resulting in data loss. Now, the common question arises like How to recover data from external hard drive? You can recover your lost data easily using relevant data recovery tool.
Data loss may also occur due virus attack, system failure, defragmentation failure, accidental formatting, partitioning errors or boot sector corruption etc. In few cases, you may not be able to access your stored data due to bad sector on External hard disk. These bad sectors on external hard drive can be detected by CHKDSK, SCANDISK or bad blocks commands. But, sometimes your computer may unusually runs CHKDSK to recover bad sectors on external hard drives. This CHKDSK may delete your essential data while repairing file system resulting in data loss.
To avoid these problems creating backup is better than recovering lost data after data loss. If your external hard drive is corrupted due to some logical problems or if you deleted some data unintentionally, then do not perform any operation on your corrupted hard drive. Do not install any recovery or repair software on corrupted hard drive because sometimes it may overwrite your data resulting in permanent data loss beyond the recovery.
