Online discussion groups are filled with panicked and disappointed users detailing experiences with recently purchased Extreme V2 and Extreme Pro V2 portable SSDs. Most users seemed to be using a 4TB model, but there were complaints from owners of 2TB drives.
There has been little public response from SanDisk, which has mostly referred online users to open a support ticket with SanDisk's technical support team. Questions about refunds have been left unanswered.
When Ars Technica contacted SanDisk about the issue, a company representative said: "Western Digital is aware of reports indicating some customers have experienced an issue with 4TB SanDisk Extreme or Extreme Pro portable SSDs (SDSSDE61-4T00 and SDSSDE81-4T00 respectively). We have resolved the issue and will publish a firmware update to our website soon. Customers with questions or experiencing issues should contact our Customer Support team for assistance."
SanDisk didn't answer questions about refunds, anything about the 2TB models, what caused the issue, or when exactly this firmware fix will come.
