I had a fairly small (<100GB) data pack organized chronologically by folders (year1, year2, .) and I bought this device , to make a copy to share with someone. I used a Lenovo Thinkpad laptop with Windows. The hard drive was recognized correctly and the first set of folders seemed to be copied to it with no problems, maybe 30 gigabytes. But after trying to copy the second dataset, I found that parts of the first datapack were missing and parts of the second datapack were also nowhere to be found. Looks like directory management was faulty. I'm not sure if this is due to a bug in the device firmware or other reasons. And I don't care Because of the cheapness I decided to just throw the device away. I think you would do well not to waste your time and money on this.
