Macintosh External Hard Drive Recovery

An external hard disk is a portable storage device helps to transfer and backup data on Macintosh machines. The hard drives support SATA, SCSI or IDE interfaces to connect the portable external hard drive for transferring files between different systems without using the network connection. Nevertheless, at many times, users experience loss of files from these external hard drive storage due to various reasons.

Major factors responsible for the loss of external hard disk data-

  • Human Mistakes: We accidentally delete files from the external hard drive instead of unwanted files. Incorrect execution of cut and paste commands whilst moving files between computer and the external hard drive can lead to deletion of the valuable data
  • Formatting the External Hard Drive: During the format process, you might select the wrong volume for formatting rather than choosing some other HD volume (Mac volume/external hard drive). Sometimes the external hard drive is intentionally formatted to get rid of corruption due to harmful threats, corruption, formatting errors, etc.
  • Reformatting Process: Sometimes it is essential to change from one file system to another file system i.e. from HFS to HFS+ file system on Mac. Errors during the file system conversion due to sudden system shutdown or power fluctuations may lead to corruption of the existing partition thus resulting in data loss
  • Repartitioning the External Hard Drive: When the size of an existing volume needs to be changed or a new partition needs to be created, repartitioning becomes necessary. The incorrect repartitioning process could hamper the data existing on the external hard drive volumes thus leading to the loss of files
  • External Hard Drive Crash: Bad sectors, MBR corruption, virus attacks, file system corruption, disk/format errors and other conflicts can lead to failure of external hard drive thereby causing data loss

How can we get back external HDD files on Mac?

The data loss occurred due to any of the pre-mentioned scenarios can be successfully retrieved with the help of an appropriate data recovery tool. Data on the external drive that got deleted, lost, or formatted are not permanently removed from the drive location until they are not overwritten by new files. File recovery becomes difficult or impossible when lost file space on the external hard drive gets overwritten by new data. Therefore, you should stop using the external hard drive for a further write operation and immediately start using the reliable drive recovery app to retrieve the files from the external drive storage.
