I bought this device in January 2017 to transfer files from my Samsung S6,  however, I not use it until later in the year when the return date has passed.  Unfortunately for me,  it did not work...... I did not get the files transfer from the phone to the device or the computer.  Now I am unable to connect my phone directly to any computer.  Also all the usb ports on my lap top has stopped working since plugging this device into it.  I am so disappointing.  Now my phone is over full and I cannot get the information from it and it will soon crash and i can plug nothing into the computer usb ports as they no longer work.  When I plug in the device seeing "ROGER'S FIRESTICK".  I would really appreciate being compensated for the lost of my usb ports on both my phone ad laptop.

This is August 2014. I bought it in early 2013. It worked initially as promised but for the last one year it looses connection on devices on and off. Something is not right.
Even wired connection becomes stale in a day. Unit requires power off and on. Interestingly my DELL laptop always connects no matter what.

Bought this 10 months ago.  I've used it mainly for large file transfers or when a wifi transfer is not available.  I've flawlessly transferred files between my Galaxy S3, Galaxy Tab S 8.4 and several PCs.  Beats using a sync cable.  I rarely give 5 stars for any review, but this purchase merits it.  I'll probably purchase the 64GB USB 3.0 version soon.

The device worked great for a while. The small size is extremely convenient, but it can be difficult to remove from a port. Write/Read speeds are fair.  I synced a local folder with a folder on this drive as a makeshift backup device. Backups would occur monthly, typically with 250mb or less data. The product stopped working recently after only about 10 months.

I have not been able to get any easy use out of this device. Connecting directly is not easy or sometimes impossible. And transferring files to it is VERY slow. I have spent DAYS transferring 1TB to it. The software WD includes doesn't work very well. I would transfer files for 5 hours and some files or folders were missing so I would always have to double check. The only way to access is via windows explorer the WD software is not reliable. This device is a waste of time.

Stopped working 2 months after purchase.  When trying to add files, there is an error message.

I does not work for the purpose I bought it for. That is, to be able to copy the contents of my SD cards on an external USB HDD without the need of a computer, for when I am on the go. First of all, the USB HDD is not detected by the device, no mater what. I have also tried to connect the secondary power usb plug of the cable to the computer or a battery, so it is not due to not sufficient power.
Second, the mobile app is not compatible to Android version 5, so you need to use another app or use the browser. Who knows when they are going to launch a new version of the app.

Bottom line, I would not buy it again. Maybe I should have gone with a WD Wireless and get the job done, but thought I would give this a try.

I bought this drive in January for my wife. It's now June and it just stopped working. Now I've got to figure out if I can recover her files. Sigh.

I got one in January, 2016 and it stopped working on July. I contacted ADATA for support for the life time guarantee and they don't even read your messages, just send you useless scripts. I would not suggest anyone to purchase one of these flash drives. I never took my USB out of my office to tell that it had a physical damage, so I can tell it was defect that just came with it.
What about my data? well, I lost it.

I purchased this drive to back up some very large files, varying in size from 6GB to 40GB. I have it attached to my MacBook Pro using the USB3 connection. The drive works, but it's really slow compared to other external devices that I own. I also own a Seagate Backup Pro 2TB drive as well as several StarTech docking stations, all of which are USB3. The WD Passport seems to take 4-5 times as long to backup my files as compared to these other devices.

I will continue to use this device, but only for very occasional backup purposes. Monthly at most. Otherwise, I'll use my other devices. I certainly can't use it directly with applications needing to update these images.

Bottom line: I won't throw it away. But I'll never buy another one.

I bought my Yourkarma device a year ago. Initially it worked great. Starting 3 months ago, however, more than 9 gigabytes of my data mysteriously disappeared without explanation. My friends also had a hard time sharing my device on numerous occasions. I wouldn't recommend this device. Now I am using my cell phone hotspot, which is much more reliable!

I was using this as a way to transfer files from my phone to my PC. After only a couple of uses, none of my devices can read it anymore and would not show up on any of the disk management tools I use. I would not recommend this device.

The device stopped working two months after i purchased it. Basically my $300 investment on this device went down the drains..

The device auto-updated while in hibernation and crashed. I tried use the restore files and it corrupted the USB and was unable to load the files on it. I will update if they send me a new one. I had this for less than a month and only used it once.

This was a gift from a friend of mine. I started using it as of February 12th, 2016. I've never dropped it or in fact carried around. It is always on top my desk. I used daily since March and right now only 30GB of 1TB is full. As of yesterday, it started making a strange clicking sound. It's considered to be "the sound of death" in tech forums. I checked the return options on Toshiba's website. They don't offer a replacement but only a Visa reward. I need to send the item and a receipt. Seems a little inconvenient but better than nothing.

One more problem with it is that even though there is an option in the program to sync with OneDrive, it doesn't sync with OneDrive Business. I even talked to customer service and confirmed it. It just doesn't sync. FYI.

So I'm manually syncing everyday and afraid that the drive may die any minute. I'm writing a dissertation and I can't risk any KB of loss, so I now have to go back to relying on cloud storage again. Maybe I just got a defective one or the hard drive is not built for everyday use.

It's red and look cute though and I like that they have a warranty. Hence 2 star.
