Dell laptops require a way to store data permanently. Your hard disk is the place where everything on your computer is stored. The programs, operating systems, saved data, pictures, movies, etc. are stored in magnetic layers on the hard disk. Introduced in 1956 by IBM, hard disks have come a long way. They are much smaller and yet have far greater capacity than they did when they were first released. Standard size is 60 GB, but HDDs will vary in other specifications that effect performance and speed of the computer.
Earlier, different types of storage devices have been used for storing the data like punched paper ribbons and cards, magnetic tape reels and cartridges and so on. But today, magnetic hard drives are used to store large amount of data. hard disks use different standards and interfaces. There are two different standards i.e. IDE (Integrated Drive Electronics) and ATA. SCSI (Small Computer System Interface) is another standard that is mainly used for high-end workstations and file server systems. Data is recorded onto the platters in a series of magnetic rings called as tracks. Each platter consists of tracks on the top and bottom surfaces. A stack of these tracks are called as cylinders. HDD reads or writes the data using heads. A single platter needs two heads i.e. one for top and other for bottom surface. Each track in turn has a number of sectors. Each sectors stores 512 bytes of data. The hard disk needs to be configured with a partition and a file system before the data can be stored. Formatting the hard drive assigns a file system to organize the data. If your HDD already contains data then it deletes and creates new file system to store new data. Sometimes, you may accidentally format the hard disk resulting in data loss. But, no need to worry because HDD recovery can be easily done by using relevant hard disk recovery tool.

Common scenarios which lead to deletion of files from Dell Laptop HD are as follows:
- Partition loss after re-installing Operating system: Most of us avoid using single partition because of logical corruption. If that partition gets corrupted, the only solution is to reinstall the Operating system. Re-installation can be done using installation disks. While re-installing Operating system, it may wipe your hard disk. If you have not taken backup before re-installing the Operating system then you may lose data from the partitions. However you can rescue deleted partition data on Windows using a good recovery tool.
- Accidentally formatting while installing multiple Operating systems: You can install multiple Operating systems on a single HDD. Each partition can have single Operating system. While installing another Operating system using installation disk, it asks for the location to install new Operating system and before installing it to format selected partition. If you select wrong partition that contains important data or old Operating system instead of empty partition then the data present on that partition get deleted resulting in data loss.
- HDD crash: The Master Boot Record (MBR) helps in booting of Windows operating system and is an important component of FAT and NTFS file systems. These file system manage data which are stored in your hard drive. So any corruption to the Master Boot Record (MBR) leads to HDD crash.
Therefore, before installing multiple Operating Systems on a single hard drive, take back up of essential files to avoid data loss. Once you find that, you have lost the filesthen stop copying or saving new files to avoid permanent data loss. Make use of relevant files resurgence tool in order to regain lost files from the HDD.
Windows Hard Drive resurgence software is an efficient file rescue tool that helps you to regain lost files from FAT16, FAT32, NTFS, NTFS5 and ExFAT formatted partitions of your Dell laptop hard drive. This software reclaims files from SATA HDD, SCSI and IDE hard drives in couple minutes. Different types of files can be easily recognized and rescued quickly by using this software. This software can also retrieve lost files from non-booting devices by creating disk images. This tool has an ability to bring back data from Windows 7 HDD, Vista, XP, Windows Server 2003 and 2008. This software can also regain lost data from non-booting drives and inaccessible partitions. Download free demo version to estimate rescued results. It can also undelete data from formatted drive and reformatted hard disks.This software has the ability to unerase data from Seagate hard drive, Western digital, Samsung, Sony, Hitachi etc in few simple steps.
Steps to undelete hard disk files from Dell Laptop:
Step 1: Download and install "Windows hard disk Recovery" software and then launch it to get back hard drive data. From the main screen select "Recover Drives" option as shown in Figure 1.
Figure 1: Select Recover Drives
Step 2: Then, select "Partition Recovery" option from the screen that appears next as shown in the Figure 2. The software will display the detected physical drives from which you need to select the physical drive from where you want to recover deleted or lost partition.

Step 3: Select the partition from the list of found partitions and then click "Next" button as displayed in Figure 3.

Step 4: The software scans selected partition. After scanning, all the data recovered from formatted partitions is displayed that can be viewed using "File Type View/Data Type View"as shown in Figure 4. You can then save scanned information using "Save Recovery Session" option.
