External hard drives are particularly prone to failure due to frequent improper use, outdated drivers, bundling with incompatible software on different operating systems, frequent connection and disconnection to different devices, and, in the case of portable or USB hard drives, unsafe ejection.
External hard drives are often used to back up important data from our Windows PCs. If the drive should suddenly stop working, it could prove disastrous. But don't worry, we'll explain how to get it working again and save those precious files.
Verbatim Unveils New Portable Hard Drives For Mac
Step 1. Use a correct USB cable to connect your external hard drive to your computer. Run EaseUS Data Recovery Wizard and you will see your external disk under External drives. This software supports all the popular external disk brands, including WD, Seagate, Toshiba, LaCie, SanDisk, Samsung, etc.

After updating this morning, I can't see certain G-drive hard drives on my MacBook pro. Some that I formatted over a year ago are fine. The two new most recent ones won't appear. I have checked that the finder show all hard drives. Disk utility doesn't seem them either. However, when I plug them into another MacBook pro that hasn't been upgraded they appear in the finder. What should I do?
FYI. In the spirit of not giving up I disconnected a wacom tablet from the computer, mostly because I don't use it and I was trying to simplify my desktop, I had shut the computer down...and magically when I rebooted the mac everything was back in its right place, all my hard drives lined up where they should be....so very happy about that! The wacom was connected via a hub. I had actually plugged a small disk into the hub to see if that would work and it did show up, too, but the reason seemed to be the wacom tablet being plugged into the hub. Just an FYI for something else to try...I'm fixed and happy!
Thanks. I'm using a MacBook Pro (15 inch-2018) with a 2.6 Ghz 6 Core Intel Core i7. I'm running the hard drives natively on the mac finder with no third party software. Your suggestion to use the disk utility to "show all devices" was great. It reveals that the newer hard drive isn't mounting, while the older hard drive from the same manufacturer, G-DRIVE is. Any other idea? I have tried accessing through a good hub using a the older usb connection with no luck. See screenshot with both hard drives connected via usb-c->usb-c cords (and I have tried switching cords, too).

The newer drives are likely using a newer chipset or perhaps even a completely different brand of chipset from the older drives. Some chipsets tend to be more reliable and more supported than others. Plus there is a chance the newer drives are using a different block/allocation size than the older drives which can easily occur with larger drives. Perhaps the newer drives are also utilizing some other new technology which is not completely compatible with some Mac hardware or perhaps only incompatible with Monterey (hopefully just temporary).
I have the exact same problem. I spent hours online last night and on the phone this morning with someone from Apple, very nice people but no joy with the hard drives. All four of my drives are no more than 2 years old and none of them show up. They do show up in Safe mode and I have tried the reset SMC multiple times. Very frustrating. Now looking at buying one new large hard drive and then having someone pull all the data over. I have both WD and G-Drive drives. The person who was helping me said he'll call me back on Tuesday and he's hoping he can find something out. I've looked all over the internet to see if WD has anything out but they have made no mention of support for Mac Monterey. All of my computer work is done from the drives, lover 100,000 photos on them. So unexpected!
Floppy disks remained a popular medium for nearly 40 years, but their use was declining by the mid- to late 1990s.[4] The introduction of high speed computer networking and formats based on the new NAND flash technique (like USB flash drives and memory cards) led to the eventual disappearance of the floppy disk as a standard feature of microcomputers, with a notable point in this conversion being the introduction of the floppy-less iMac in 1998. After 2000, floppy disks were increasingly rare and used primarily with older hardware and especially with legacy industrial computer equipment.
Although hard sectored disks were used on some early 8" drives prior to the IBM 33FD (May 1973), they were never widely used in 5-inch form, although North Star clung to the format until they went bankrupt in 1984.
By the early 1980s, falling prices of computer hardware and technological advances led to the near-universal adoption of soft sector, double density disk formats. In addition, more compact half-height disk drives began to appear, as well as double-sided drives, although the cost of them meant that single-sided remained the standard for most home computers, and 80-track drives known as "quad density".
By the end of the 1980s, the 5-inch disks had been superseded by the 3-inch disks. Though 5-inch drives were still available, as were disks, they faded in popularity as the 1990s began. The main community of users was primarily those who still owned 1980s legacy machines (PCs running DOS or home computers) that had no 3-inch drive; the advent of Windows 95 (not even sold in stores in a 5-inch version; a coupon had to be obtained and mailed in) and subsequent phaseout of stand-alone MS-DOS with version 6.22 forced many of them to upgrade their hardware. On most new computers, the 5-inch drives were optional equipment. By the mid-1990s, the drives had virtually disappeared as the 3-inch disk became the predominant floppy disk.
An MFM-based, "high-density" format, displayed as "HD" on the disks themselves and typically advertised as "1.44 MB" was introduced in 1987; the most common formatted capacity was 1,474,560 bytes (or 1440 KiB), double that of the 720 KiB variant.[nb 4] The term "1.44 MB" is a misnomer caused by dividing the size of 1440 kibibytes (1440 * 1024 bytes) by 1000, thus converting 1440 KiB to "1.44 MB" - where the MB stands for neither a megabyte (1,000,000 bytes) nor a mebibyte (1,048,576 bytes) but instead 1,024,000 bytes. Correctly dividing 1440 KiB by 1024 gives a size of 1.40625 MiB. These HD disks had an extra hole in the case on the opposite side of the write-protect notch. IBM used this format on their PS/2 series introduced in 1987. Apple started using "HD" in 1988, on the Macintosh IIx, and the HD floppy drive soon became universal on virtually all Macintosh and PC hardware. Apple's FDHD (Floppy Disk High Density) drive was capable of reading and writing both GCR and MFM formatted disks, and thus made it relatively easy to exchange files with PC users. Apple later marketed this drive as the SuperDrive.[69] Amiga included "HD" floppy drives relatively late, with releasing of Amiga 4000 in 1992, and was able to store 1760 KB on it, with ability in software to read/write PC's 1440 KB/720 KB formats. 2ff7e9595c
