I own two Sandisk Extreme Pro Portable 2 TByte (SDSSDE81-2T00) and I had no problem till today, but it seem that the SSD produced in the end of 2022 have some problems...
here a translation of a german site:
https://www.heise.de/news/Externe-Sandisk-SSDs-fallen-am-laufenden-Band-aus-9247983.html
it concerns the Sandisk's Pro-G40 too, have you some information about it?
Many Sandisk external SSDs produced since the end of 2022 are not running reliably. Since the beginning of the year, more and more reports have been increasing that operating systems can no longer access the disks. The stored data is practically no longer accessible.
The hardware does not seem to be broken per se. Instead, there are problems with the file system, regardless of the format and the operating system. For example, the SSDs say goodbye under Windows with FAT formatting, but also under macOS with HFS+. There are numerous reports on Reddit and .
The Arstechnica, The Verge and Petapixel websites also . In all cases, Sandisk ignores press inquiries and public contributions. Also a request by heise online on the 10. August has remained unanswered.
Insufficient firmware updates
On a support page, the Sandisk native Western Digital (WD) only that several external SSDs need a firmware update because they can "disconnect it unexpectedly from the computer." The company does not write anything about the possible data loss. On the page WD also lists its own SSD:
Sandisk Extreme Portable 4 TByte (SDSSDE61-4T00)
Sandisk Extreme Pro Portable 4 TByte (SDSSDE81-4T00)
Sandisk Extreme Pro Portable 2 TByte (SDSSDE81-2T00)
Sandisk Extreme Pro Portable 1 TByte (SDSSDE81-1T00)
Western Digital My Passport 4 TByte (WDBAGF0040BGY)
On the page you can use the search field to see if your own serial number is affected. The information provided by a distributor and user reports indicate that the problem occurs with models that have been produced since November 2022. According to reports, Sandisk's Pro-G40 also seems to be affected.
Meanwhile, the firmware update does not seem to create reliable remedy. The current versions have been available since May, but since then the problem reports are still frequenting – including people who have updated the firmware update.
