Transcend Jetdrive stopped working properly

Within the Ventura "Security & Privacy" System Settings, look for an option "Allow Accessories to connect" and set it to "Automatically when unlocked". If this setting is already configured this way or to always allow, then toggle it to another setting, save it by clicking in another tab of System Settings, then put this setting to "Automatically when unlocked", or if this does not resolve it, then set to "Always". I saw another user post that for some reason a macOS broke this setting for them or reset it...I believe the default setting is "Ask Everytime".

I have seen some people mention this issue with the built-in SD card slot in the Apple Silicon Macs. I believe it is not specific to any brand or model of SD card, although I have seen a lot of posts in the past year regarding Ventura and Transcend Jet Drives (not sure if SD cards, SSDs, or USB sticks). I believe a few people mentioned using a third party SD Card reader worked for them when the built-in SD reader was not (same issue requiring physically removing & reinserting the SD card).

FYI, I will never expect anything to be fixed soon if at all. Unfortunately Apple never tells anyone whether they are aware of an issue much less whether it is being fixed. "Soon" is very relative. It can easily take a vendor several months to fix a bug once they actually start to focus on it. Hopefully enough people submit product feedback so that someone at Apple takes notice and encourages the bug to be fixed.

Just a thought. Have you tried opening Disk Utility and mount the Jetdrive from there?

I agree, the bug occurs in the side card slot. It happens on all cards you insert in the side slot, not with usb memories, so it is a bug that occurs since at least macOS Ventura 13.4. It also happens with the new MacOS 14 Sonoma.

Hi there,

I wanted to share that the issue with Jetdrive memory also occurs with other types of memory (with Kingston also occurs).

It seems that Apple has removed the functionality to detect inserted memories without having to remove and reinsert them. It's important to be aware that the issue is not specific to Jetdrive alone.

The same with my Transcend JDL 330 1 TB. After 13.4 it is not automounted after boot I need to un-plug it and then insert again. Before this manipulation DiskUtility do not see it also. Very annoying me because I'm use as TimeMachine drive. Try another new one JDL 330 and standard SDCARD from another vendor - all the same.

Sadly doesn't work as of 08292023. Currently running 13.5.1 and I have tried everything that has currently been posted on the net on work arounds. This is very annoying and outright dumb. Apple needs to send an update immediately to fix this. I have lost GBs worth of work. Sure backups are ideal but shouldn't have to rely on them nor should they be relied on. Very frustrating.

I see. Someone else is having an issue with a JetDrive on a 2015 MBA running Mojave.

This bug surely will be solved in the next Mac OS version update that will be delivered very soon.

Apple is listening carefully customers requirements.
