All computers and storage devices are subject to issues at some point in their lives. The main reasons are human errors, software or hardware malfunction, virus attacks etc. When we say human errors, the most common thing that comes to mind is removing USB or hard drive without ejecting it.
This article is focussed on the consequences of abruptly removing a hard drive and how you can protect yourself from data loss should something happen.
Why should you eject a hard drive?
Consider a situation where you connect a hard drive to transfer data. If you remove the drive assuming that data transfer is complete, chances are it’s NOT, because the OS isn’t going to write to the disk immediately for every small operation. Only when you eject the drive, the buffered read/write operations are completed. So, it is very important that you ‘Eject’ the drive after use.
Also note that ejecting is not applicable to only ‘external hard drives’, but also for ‘memory cards’ and ‘USB flash drives’. There is a false notion that it is not applicable to flash drives as they do not contain moving parts, but it’s untrue. They use the same OS read/write buffer mechanism, so you should always consider ejecting it before removal.
In some cases, nothing may happen even if you pull the device without ejecting, but it’s all about timing and whether the necessary shut down operations is complete. The following are consequences you’ll face if you remove the hard drive from your Mac without ejecting it.
- Meta data corruption
- File system corruption
- Partition table/map corruption etc.
What happens if a drive gets corrupted?
If a drive experiences corruption; depending on the severity, it may become read-only or in worse cases, it may become completely inaccessible. You’re lucky if it turns read-only as data can be restored without any difficulty. However, you will need professional help such as Remo Recover if it becomes inaccessible.
Remo Recover: Data recovery made easy
Remo Recover is a great tool to recover data from corrupted or inaccessible hard drives. It can also be used hard drives that won’t mount.
The software is designed to work with all file systems such as HFS, HFS+ etc, and all recent Mac OS versions including Sierra, so you’ll have no problem with compatibility.

Then perform a few clicks and your data can be recovered easily. A simple interface is provided to make data recovery simple for non-technical folks as well.
As a precautionary measure
Always make sure you safely eject the hard drive before removal. It is only a matter of a few seconds, so there’s no reason why you should not get into the habit of doing it regularly. Doing so will protect the drive from corruption and data loss issues and also save you from worries.
