Both drives had issues.  USB connection problems when it was working.

I purchased two.  One arrived broken, the other worked 90% of the time for about 20 uses.

After this, the second drive went bad as well.

Even if you get a drive that works, the very short pigtail USB-3 cable (about one foot) has very loose connections.  some other reviewers noted that if the USB connections are not sitting just perfectly, the drive disconnects or has errors.  This was my experience in the roughly 20 times I used the one working drive.

The one good thing I can say, is that it is a very easy case to open and insert a drive, requiring no screws.  For that reason, I really wish I could give it a good review.  Unfortunately they were horrible enclosures that wasted hours of my time and eventually went into the trash.

The drive did not work. Got a message "the disk cannot be read"

I tried connecting it my Western Digital portable hard disk and the connection is not at all stable. It connects and then disconnects immediately and then connects again and on and on. These are not data cables, they are charging cables.

For the short time I had the drive it worked very well. Then it got corrupted (99.5% sure this was my fault) and I haven't been able to use it since.

I use a lot of USB drives for various purposes and over many years I have tried dozens of different models/sizes from brand name companies and most of them are still going strong. I purchased several of these about 12 months ago when they were on sale at a local big box store. Unfortunately since then I experienced problems with most of these drives and 2 are total failures. They randomly indicate various hardware errors after copying data and 2 cannot be recovered. I still have a couple in the original packaging but I am reluctant to use them because they are so unreliable. Maybe I got a bad batch but I cannot recommend these drives.

I bought this drive 3 months ago.  I have always been happy in the past with maxtor drives.  I have a Macbook pro which only has 2 USB slots, so in order to use this drive (which draws power from 2 USB slots) and my computer fan, I had to get a USB hub to create more USB's.  The drive did not like only being plugged into the hub.  It did not show on my desktop.  With a few restarts and plugging one of the lines directly into my laptop the drive came back on-line.  Just a few days ago I had several flash drives plugged into my usb hub and my maxtor mini connected.  The computer became busy.  I had to shut it down.  When I started it back up my mac did not recognize the format of the drive and the drive won't mount anymore.  I have tried erasing and partitioning the drive, to no avail.  Disk Utility just stops responding while trying to perform the partition or erase.  The drive is light, beautiful, big, great price and I thought a good manufacturer, but has been continuous problems.

Endless problems with USB storage.
File/Folder permissions access denied (never resolved till this day and no one has answers)
Constant loss of connection to USB storage when transferring large amounts of data (For example applying properties on multiple files or transferring many files) connection with USB storage gets lost.
Everything else is OK so far but i did have signal lost while modem was still online and working.

I think its garbage.

I purchased this drive from Amazon a year ago, and it has recently stopped working. I can narrow the cause down to something about the ability of the drive to receive power or the drive unit's usb. (Note: I am not saying the cable or the plugs on the other side -- I have a 2TB Seagate of the same kind more recently purchased that does not have these issues and which has interchangeable USB cables and power supplies).

I'm really disappointed at how quickly this drive broke. Neither power supply and neither USB cable seems to make a difference.

I did like this hard drive until it failed on me whenever I needed it the most. I've had it a year now. I think the connector is bad? Idk. Frustrating.

This worked fine for the first month or so of owning it, but out of nowhere both drives lost their partitions, both at the exact same time.  I've unplugged them a few times and tried rebooting and neither have readable partitions at all.  Since they were both plugged into here and both went at the same time it had to have been the device that did it.

2 of the drives were defective. I notified amazon and did not heard anything back. Disappointed.

Had to fix an issues that the USB ports were not working. After looking around in the system and downloading a couple of drivers I fixed it.

Really Upset. This drive has completely failed on me and was used for less than a year. I'm hoping the company/amazon will help reimburse me for this drive. It's literally a pain trying to transfer my information to another drive. After about 30 seconds it just dies. Now, it won't spin up and does not show in the bios nor disk manager. Can someone make this right?

The drive was recognized when I had unboxed and started using it on my main desktop, although there were already faint clicking sounds in it's idle state. As soon as I had started to migrate Steam games from my desktop to the USB drive, there was a "DISK WRITE ERROR" that occurred and the drive was no longer recognized. I have since returned this drive to Amazon and they gave me a full refund.

Worked less than 30 days and USB connection stopped functioning.

Bougth two of these 16GB USB 3.0 flash drives. Only one drive worked in a 3.0 slot. The other drive was defective and would only work in a 2.0 slot. Amazon says I can't return the defective item for some reason. Frustrating because I'm now stuck with a product I didn't order.

Connection to more than one drive drops and fails, almost ultimately crashing my entire OS. Forcing me to restart.
