    There's been issues with this drive since a week after I bought it. It keeps disconnecting itself, stopping my workflow and forcing a restart. I have several of the same drive that work fine (purchased from other stores than best buy) but this one in particular is faulty and I haven't had the time/don't want to deal with the headache of getting a refund and also having to move like 3 tb of files that I need for active projects :/

    No, I would not recommend this to a friend

      Sorry to hear about the issues with the drive. Frequent disconnections are not normal. We would suggest you to kindly try using a different cable or connect the drive to a different port/different computer and check again. If the issue continues, please get in touch with the support team for further assistance by opening a ticket at (https://support-en.sandisk.com/app/askweb) SanDiskConnections
