Sandisk Extreme Pro 2T unreliable/unusable on Macos Ventura

This is 2nd unit of Sandisk Extreme Pro 2T in a few days, as I initially thought the problem was coming from the first unit. I send back the first unit and ask for a replacement. But same thing. It seems to be a MacOS problem. I'm running macOS Ventura 13.2.1 on a MacBook Pro 2019.

After a few hours or couple of days, the Sandisk Extreme volume becomes unresponsive and all the data in it are lost. The device lost the content, even its name. Remounting the device, formatting it again will only allow repeating the same disaster few hours or couple days later.

Needless to say that this is totally unacceptable nor even thinkable.

Does anyone has experienced this. Apple please provide an decent answer to this!

MacBook Pro 15″, macOS 13.2

FYI,

it looks like, according to other forum inputs, that this is an issue related to the Thunderbolt 3 in USB 3.1 Gen2 mode and the 3.2 Gen 2x2 interface of the Pro Extreme SSD drive compatibility, indeed more likely in the camp of Apple. Since neither Apple nor SanDisk provided actionable answer or even feedback, I returned the second drive and went for a Samsung T7. In my case, this is ok, since I wouldn't have gotten more transfer speed with the Extreme Pro anyway. The T7 works fine now for a couple of weeks.

I bought a sandisk ssd 1tb and its not showing/reading in my mac air m1. I went to the store to replace thought of to be a damaged product but after replacement also it's still the same.

But i checked with sandisk 480 gb version ssd and it was showing.

Has any one any idea about it???

Hi,

I'm having the same issue with Monterey 12.5.1 with the 2T version.

I really thought the SSD had a problem.

Thank God I didn't erase the files from my previous drives after copying them.

Best,

See my comments above. I am quite certain this is a bug in MacOS as my Sanddisk drive works perfectly in Windows.

I formated the drive unter another mac with Monteray, and it seems that it is not working on the Ventura fine; more test is needed, but I disconnected it several times, and the data is still there on the VEntrua MAC Book.
