Hard drives are widely used as a primary storage device to store large numbers of files, including different operating systems like Mac and Windows OS. Windows mainly support FAT and NTFS file systems that support Mac HFS and the HFSX file system. Mac OS has read-only access to NTFS partitions. Data loss due to accidental deletion is a common problem for both Mac and the Windows operating system. Some people think that when you delete the file using Shift Canc or Command Del key combinations or the command prompt, they are permanently deleted because they don’t find the deleted files in the Recycle Bin or Recycle Bin. But this is not true; they are still present on the hard drive until the new files are stored on that drive. You can click here for the best information.
Suppose you have deleted a file called xyz.doc from your hard drive. When the file is deleted xyz.doc, the file system to simply rename the specific file αy.doc and this file cannot be recognized by the Windows operating system due to that file becoming inaccessible. In reality, the file system allocates the breakdown information of that specific file to zero, which informs the operating system that the space available to store the new files. Furthermore, data loss can also occur due to other common reasons in Windows and Mac such as,
- Corruption file system
- Accidental formatting or reformatting the hard drive
- Malware, spyware or virus attacks
- Accidentally clicking on “Empty the Recycle Bin or Recycle” option
- Catalog and corruption of the Journal file
- Accidental conversion of the dynamic disk to basic disk
- Corruption header volume
- Accidental deletion of partitions or volumes with third-party partitioning tools
Precautions that must be taken to avoid file loss
Backup: the backup is the best way to avoid file loss due to complex data loss scenarios. If you have already taken a backup of the entire hard drive, you can easily restore accidentally deleted or lost files from your hard drive
Using effective antivirus programs: Viruses are malicious programs that destroy files stored on your hard drive. Typically, viruses spread while transferring data from the already infected computer. Therefore, use up-to-date antivirus programs to remove viruses before transferring files to infected computers. Always, scan external drives like pen drives, memory cards for viruses before starting the process data transfer
Double-check while deleting files: always, double-check while deleting files using Shift Del in Windows, Delete keys in Mac command and Windows Command prompt. Because, files that are deleted using Shift Delete or Delete Command ignore the Recycle Bin or Recycle Bin, which cannot be restored later by the Recycle Bin or Trash.
Precautions that must be taken after data loss
Stop using the drive: If you have already lost files from your hard drive, then avoid using the drive. Because saving or copying new files to this storage location can overwrite old files that already exist in that specific space resulting in permanent loss. Do not install recovery software on the same hard drive: if you plan to use any file recovery tool then do not install it on the hard drive from which you want to recover accidentally deleted or lost files.
