Problem Solved - MacBookMac is Not Recognizing External Hard Drive

After you connect a removable disk through the computer’s USB port or SD card slot, the Mac OS will read the drive and mount it on the desktop, in Finder, and Disk Utility. The Mac OS always enables you to have the most convenient access to open the disk and manage files on it.

However, people may not go as quickly as you expect. MacBook Air/Pro may not show up the external hard disk at all. One the one hand, the disappeared disk icon makes it inconvenient to open the drive. On the other hand, the disk might be corrupted and result in data loss or difficulties in file transfer.

After reading the article, you will learn:

  • Why the MacBook doesn’t recognize the external hard drive
  • How to make the MacBook detect the external hard drive
  • Solving external hard drive not showing up problem
  • An easy way to recover data from the unrecognized external hard drive

1. Why is the MacBook not recognizing my external hard drive?

The recognition process of an external device contains two parts – hardware and software. Any problems in either of the two parts will end up with the macOS doesn’t detect and recognize the external hard drive.

We summarize four common reasons:

  • The USB port/USB adapter/USB cable is broken.
  • The external hard drive is physically damaged.
  • The incompatibility between the file system of the external hard drive and the Mac OS.
  • The file system/partition table/other core information on the external hard drive is corrupted.

2. How to make the MacBook detect my external hard drive?

The very first step of solving the problem is to check the hardware conditions of the connection and the hard disk itself.

a) Use a different USB port/adapter/cable

After plugging and unplugging for multiple times, the USB/port/adapter/cable may get worn out or become wobbly if you have spare ones, the go-ahead to use them.

b) Reboot the MacBook | MacBook Not Recognizing External Hard Drive

If you didn’t eject an external drive safely before you attach another one to the MacBook laptop, the computer might believe the USB port is still unavailable. As a result, the MacBook may not accept another external drive. Then you need to restart the computer and reconnect the external hard drive to it. After rebooting, the OS will release the USB port to the external hard drive.

c) Connect the external hard drive to another computer

If you are sure that the USB port/adapter/cable is all good and you have restarted the MacBook, but the problem stays unsolved, try to find another Mac or PC to see if the external HDD can be detected. Did you ever drop the external hard drive? If you did, the disk might suffer physical damages that prevent it from working correctly. Let it go and get a replacement.

3. Solving the external hard drive not showing up problem

Solving the external hard drive not showing up problem

Sometimes, your external hard drive is recognized by macOS, but it doesn’t show up on the desktop or in Finder. It makes you feel your external HDD is not known. To see if that is the case you come across, go to verify a few settings.

Go to the top menu bar where the Apple logo is and click on “Finder.” Select “Preferences,” and you will see four tabs on the top. Tick “External disks” under “General” and “Sidebar” tabs. Then the MacBook is set up to show up the external hard drive on the desktop and in the Finder.

Solving the external hard drive not showing up problem

If all settings look useful to you, the removable hard disk not showing up problem might result from the incompatibility between the file system and the MacBook, or the corrupted file system of the external hard drive. To make the external HDD work properly on MacBook, you need to erase it in Disk Utility. A small reminder: the erasing will deleted all your data.

4. An easy way to recover data from the unrecognized external hard drive

Many people probably won’t realize that they are facing a threat of data loss until they are. Fortunately, professional and reliable ransomware data recovery services are available for you. They are very efficient in restoring the essential pictures, videos, documents, and other files from the unrecognized external hard drive.

WORM-Compliant Storage: Exploring Write Once Read Many (WORM) Functionality

This is sometimes referred to as write once, read many, or WORM, compatible storage. With a name like that, it’s hardly surprising that many need help understanding it.

How does WORM storage work

Organizations generate an immense quantity of data, yet sometimes they need or want to preserve it in an unalterable format.

For legal reasons, a non-profit organization may desire to keep its financial information in this format regularly. An institution may desire to save graduation records in this manner in case the actual records are lost in an accident. Businesses may desire unalterable records to avoid tampering, which might cover up fraud.

This is sometimes referred to as write once, read many, or WORM, compatible storage. With a name like that, it’s hardly surprising that many need help understanding it.

We’re here to help you get a grasp on things. Let’s go!

1. What Exactly Is Write Once, Read Many?

The simplest explanation is that it is immutable storage. You may write data to the storage device or medium just once. Following that, no one may legally alter the data in any manner.

CD-R discs are a basic kind of WORM storage. You may add data to the blank disk, but it will remain in that state indefinitely. You may damage or destroy the disk to prevent someone from accessing it, but you cannot modify the data contained in it.

WORM storage allows for repeated reads of the data. Assuming the disk or drive isn’t destroyed, there’s no practical limit to how often you can access the data.

2. How does WORM storage work?

There are two options for implementing WORM storage in your business. The first technique is hardware, which uses tape or a similar form of media that permanently stores data, making physical destruction of the WORM storage device the sole way to delete it.

Nonetheless, with many solutions migrating to cloud and SaaS services, selecting particular hardware might be challenging. However, many of these service providers now provide software-defined WORM solutions, which combine the flexibility of software with the strictness, security, and indelibility of hardware-based WORM.

Whether you utilize software or hardware to achieve your compliance objectives, the idea is the same. When someone writes data to a WORM disk, it remains there eternally. The assumption that you cannot alter the data on a WORM drive only refers to anything that has already been saved there; the ability to add new data is always available as long as there is adequate storage space on the drive.

Do you need WORM-compliant storage

3. Do you need WORM-compliant storage?

Unless your company works in the securities or healthcare industries, which are subject to SEC or HIPAA laws, there is likely no legal need to adopt write-once, read-many (WORM) compliant storage solutions. However, legal requirements are only one motivator for using WORM storage systems.

WORM compliant storage provides a key role in addition to regulatory compliance. For example, if you want to keep a safe archive of historically important documents, WORM storage is a wise solution. This guarantees that once data is written, it cannot be changed or erased, protecting the integrity and validity of critical documents over time.

Furthermore, in situations where internal workers may tamper with corporate documents, WORM storage adds an extra degree of protection. Creating immutable copies of papers makes it easy to check the correctness and validity of records, reducing worries about possible manipulation.

Likewise, WORM storage may serve as a protection for proof of trade secrets or intellectual property, providing a snapshot of data at a given point in time and preserving valuable assets from illegal changes or access. In conclusion, although WORM-compliant storage is not legally required for all enterprises, it provides essential advantages for data integrity, security, and crucial information preservation.

4. What are the primary advantages of WORM storage?

WORM technology protects businesses against many of the usual difficulties associated with data corruption and loss. The primary advantages of deploying WORM storage include:

Compliance With Industry Regulations

Using WORM storage helps firms comply with recordkeeping rules and laws. More than simply archiving data is required. Businesses must store their data in the right, unalterable format to comply with regulatory requirements and avoid significant fines and penalties.

Risk Mitigation for Poorly Archived Data

Companies must have a robust procedure for archiving all data. If information is needed as part of an audit or lawsuit and the required data is lost or damaged, difficulties (and penalties) will arise.

Better Information Security

WORM Storage secures precious and sensitive data and, more critically, prevents it from being doctored or changed. It guards against occurrences such as data being accidentally or purposefully manipulated.

Better Data Governance

WORM storage contributes to the present business-wide practice of rigorous and well-planned data governance. It also enables you to better adhere to the Electronic Discovery Reference paradigm (EDRM), a paradigm that describes the steps of the eDiscovery process throughout an inquiry.

5. Use Cases of WORM Storage

Professional content distribution includes financial records, police investigations, court testimony, computerized voting, and other applications in which data files must be safeguarded against manipulation or deletion, particularly when material is accessed, relocated, or transferred. Organizations transfer all data given over to the data investigation business onto WORM disks, ensuring that nothing changes beyond that point.

Transferring a read-only file across a network using encryption and passwords does not ensure that the file is original or untouched. Furthermore, it is usually preferable to enforce something in hardware rather than software since when the program is not operating, the data may be tampered with.

  • Corporate records
  • Financial and Insurance
  • Intelligence collection
  • Law enforcement
  • Electronic Voting
  • Court Proceedings
  • Medical Records and Devices
  • Public Records
  • Artificial Intelligence
  • Cyber-attack protection
  • IT security and log files

Conclusion

Write once read many compliant storage enables enterprises to safeguard information in a method that no one can tamper with. This may occur with something as basic as a CD-R or with software-based cloud storage.

The size of the data typically influences the medium used. You can keep a few papers on physical media without issue. Petabytes of data need a strong in-house storage ecosystem or a cloud storage provider.

If you decide to use a cloud storage provider, be sure to inquire about the retention term choices and redundancies.
