## Customer Reviews

### ⭐⭐⭐⭐⭐ external hard drive use
*by S***7 on January 14, 2024*

Using this hard drive on a star tech data dock a seat cable connected to my security camera for extra storage...works great

### ⭐ Dead on arrival
*by N***J on August 4, 2024*

I ordered this HDD as a replacement for a failed drive in a video surveillance system that had failed. It arrived quickly but did not work. It would spin up but it refused to initialize on either a Windows or a LINUX MACHINE. i NOTED THE MFG DATE ON AND IT WAS 2014! over 10 years old!!. I cannot prove it but I suspect these are old drives removed from out of service equipment and resold as new. I could not find any information on the advertising that these drives were anything but new. I had them send me a replacement and it has not arrived yet. I would be very suspicious of this company until they can prove otherwise that these drives are not used.

### ⭐⭐ Appears to be a reconditioned drive; not new
*by L***. on August 24, 2023*

Does not appear to be in original packaging. I suspect this is a reconditioned drive; not new, as listed. Note the use of a ULINE anti-static bag (in the photo), and the drive was wrapped in bubble wrap, and shipped in a plain brown ULINE box. Will amend review if the drive functions as it should.
