The complaint alleges the Western Digital SanDisk 2TB Extreme Pro SSD purchased by plaintiff Nathan Krum in May for $180 failed because of an undisclosed flaw, which also affects SanDisk Extreme Pro, Extreme Portable, Extreme Pro Portable, and WD My Passport SSD models since January 2023.

Western Digital customers "have widely reported drive failures and data loss,  Western Digital is aware of the problem and not doing enough about it, " the complaint adds.

The SanDisk Extreme Pro SSD hard drives are sold under the WD My Passport brand, have a firmware issue that causes them to disconnect or become unreadable by computers," the complaint says.

We have reported before that the drives can break down by randomly disconnecting from their host, which could result in information not being saved correctly or file-system corruption.

Once that happens users can not access their stored documents, making the SSDs worthless and useless, it is claimed.

The complaint alleges breach of contract, violation of consumer protection law, and misleading advertising, among other claims, and seeks damages, legal costs, and other relief.
