This worked great until I had an issue with one of the computers I use at work. The hard drive crashed and I tried to recover it with this drive and time machine. The computer kept rebooting and it took my drive with it. I don’t know if this was the reboot or my frustration hooking it up and disconnecting it. Needles to say it’s gone and the info is gone. Be careful with these drives as they’re not bulletproof. Don’t let it bang around in you backpack, bag, or case. I liked the product and got another one from the manufacturer but the data was lost. I backup to my cloud connections. One from work, one to iCloud, and anywhere else this one is to preserve the data when the cloud is not available
