I'm glad to inform you that my problem has been successfully resolved by purchasing a brand new HDD from the Apple store. I have replaced the faulty disks with a Sandisk G-Drive Armor ATD, which has a storage capacity of 1 TB. The cost of this disk was 3690 baht. Earlier, I had both disks (TOSHIBA and Samsung) tested on both a PC and a Mac. The test revealed I/O errors on both disks, and attempts to reformat them proved unsuccessful. They are unusable.

I now also suspect that these could be fakes. However, I am not an expert to judge that. The images show the SAMSUNG and TOSHIBA labels.

Is it possible that I've identified the error that's causing this issue? The terminal indicates that the format is NTFS, which I believe Mac cannot write to.

DISK INFO

The disk isn't displayed in Finder neither Desktop.

Yes, but unfortunately without success. Now, I'm planning a visit to Pantip as I'm running out of alternatives I've tried all the solutions mentioned in this thread. I've been working with Mac computers for over 30 years and, despite my "Mac knowledge", I can't seem to resolve this particular issue

In the "About This Mac" section, under the "Storage" tab, an issue arises when the TOSHIBA storage device is connected, triggering an immediate error message. However, I simply proceed by clicking on the "ignore" option. Although the TOSHIBA storage device is visible, it is not accessible through the Disk Utility tool. The "First Aid" feature still functions properly and can be utilized.

It's an absolute nightmare... Both disks are displaying the exact same error message. The first disk, as indicated in the TOSHIBA report, exhibits the issue, and the other disk, a Samsung, is also encountering the same problem. Disk Utility - TOSHIBA: Running First Aid on “” (disk5s1) Repairing file system. Volume is already unmounted. Performing fsck_exfat -y -x /dev/rdisk5s1 Checking volume. Checking main boot region.

I'm grateful for your tips. Thank you, everyone

The major issue at hand is that despite my efforts, any attempt to partition, erase, or format the disk fails. Furthermore, I am unable to successfully mount the disk, leading to the operating system's failure to recognize it.

It fails.

A coworker has kindly provided me with two portable hard disk drives (HDDs) that are nearly new, approximately three weeks old. When I checked in the Disk Utility, I discovered that each disk has an unformatted partition of 2 TB. Unfortunately, I am unable to perform tasks such as erasing, formatting, or mounting the disks. In an attempt to resolve this issue, I also tried creating a partition while in recovery mode, but this attempt also ended in failure. Consequently, my next course of action is to take the disks to a computer shop and have them tested for any potential physical damage. Would you happen to know of a trustworthy computer shop in Bangkok (BKK) that you could recommend? Alternatively, do you have any advice on how I might be able to format the disks and get them recognized by the macOS Catalina system? Thanks guys
