External hard drive not mounting after Ventura update

Had the same issue, took me a day and solved it. When looking at the window the Seagate disk was disable (icon in grey).

When checking the version of my NFTS said it was up to day but solved it installing the software, rebooting and reinstalling it again from its website.

If it’s formatted to work on mac and pc you’ll most likely have an app like NTFS for Mac. If so, update the app to the latest version and it should mount with ventura. that worked for me

Having the same problem. I'm using a Seagate HDD. I can open the drive in read only mode using NTSF for Mac, but not read and write so it's not an issue with the cable or ports. The drive works on my other Mac that is still running 13.2, so my guess it is an issue with the software update, maybe an incompatibility with NTSF for Mac. I'll be backing up everything to an SSD drive using my other Mac and wait this one out until the glitch is resolved with a future update.

Uploaded update the NTFS for Mac @May2023.

NTFS for Mac then opened my WD 2TB SSD and allowed read and write.

All good.

[Before doing this it was panic mode...and am considering back up somewhere. Any suggestions? Cloud service, Apple Google etc?]

Update your Paragon NTFS from app, it works fine.

Hi

Can't reproduce on my side.(but not on exact 13.3)

Check the connection: Make sure the external hard drive is properly connected to your Mac. Try unplugging and replugging the cable or using a different USB port.

Restart your Mac: Sometimes, simply restarting your Mac can fix issues with mounting external hard drives.

Or maybe check this article for detailed steps:

Yes, just updated to Ventura 13.3 and all external drives will not mount unless formatted for Mac OS. I have a paid version of Paragon NTFS, and that sees the drives, but external NTFS drives still won’t mount. I believe 13.3 has an issue with anything formatted as NTFS. Formatting a drive as Mac OS solves this, but I need to mount NTFS drives. Hope they fix this soon.

You have to go to the Paragon software company’s website and download the latest software. It costs $19.95. This will solve the problem. I hope it will help you. Look at Pennypoets post for the download link.

After updating to Ventura 13.3.1 (a) my external WD (5Tb) drive would no longer mount ntfs partition. (partitioned to apfs 3Tb (for Time Machine) and ntfs 2Tb. I followed the instructions from Pennypoets' post to uninstall NTFS for Mac, rebooted, reinstalled from provided link to version 15.10.593. and rebooted. The ntfs partition now mounts but is read-only so I see no point in having the free version of NTFS for Mac as macOS already supports ntfs read-only AND I am loath to pay for NTFS for Mac with full read-write capabilities as my computer came with that program and option preinstalled. The ntfs partition is fine in Windows 10 from BOOTCAMP. I can see from the other posts there is no solution (other than $$$) so am expressing my displeasure.

I've used Paragon NTFS for Mac for years now, with no issues until now. The point is that the software stopped working after an OS update.

Yes, that is what happens with low-level system modifications. The company that makes them should be checking against the developer betas and push an update before the macOS release. If you have to run one of those, you should be subscribed to a mailing list from the company to get informed about upcoming problems and fixes.

The full paid version does work very well, most of the time. The free versions bundled with consumer hard drives fail on almost every update.

I was wrong on one thing. The $19.95 Paragon Software is needed to make your Mac's external hard drive both readable and writable, otherwise it'll be a readable only disk. After installing the software, restart your Mac and then you'll be able to write files onto the external hard drive.

If your external HD is not NTFS then try the following in order as needed:

1 -  Reset NVRAM or PRAM on your Mac - Apple Support (for Intel Macs) and Mac startup key combinations - Apple Support (for both types)

2 - How to reset the SMC of your Mac - Apple Support

I converted all disks to ExFAT from NTFS. This issue should occur again near future. :)

I found it out that Paragon never promises my data with this issue happening.

Did you restart your Mac after uninstalling the old NTFS and again after installing the new version?

Connect the drive to whatever operating system and you can then look at it with most any disk utility software to see what format the disk is using. There's more than a hundred ways to look at the disk format across all operating systems. On macOS it is Disk Utility or diskutil. On Windows its Disk Management or diskpart. On Linux... well that's where a hundred other ways come into play.

Here are the supported file systems FAT -> exFAT is short for the long list of FAT file systems):

Linux uses ext4 / btrfs / zfs / xfs / FAT -> exFAT (there are even more )

macOS uses HFS+ / APFS / FAT -> exFAT / Read Only NTFS

Windows uses NTFS / FAT -> exFAT

The exFAT format is the most compatible across all operating systems. Allowing you to connect the drive to all of them and read/write data. Thumb drives using flash chips have traditionally been formatted as FAT so they work out of the box.

Many external drive manufacturers will format NTFS unless they are a major brand associated mostly with Apple. Such as LaCIE drives which usually come formatted with HFS+.

It is easy to reformat a drive, but you will lose all data when do so. Therefore, determine how the drive will be utilized and format it appropriately. If it's an SSD and only Macs will be using it, use APFS. If it's an HDD and only Macs will be using it, go with HFS+. If you need to share the drive between operating systems then format with exFAT.

Let's say you dual boot a Mac with Windows, that might be a good reason to format the external drive as exFAT or you can format it with NTFS and buy Paragon NTFS software. But then you need to keep it up to date when upgrading macOS you should first check if you need to upgrade Paragon NTFS as well.
