USB Flash Drive 2000GB, 2.0 USB Thumb Drives YSeaWolf for Computer/Laptop, External Data Storage Drive with Rotated Design, Memory Stick, Jump Drive Storage for Storing Photo/Video/Music/File(Black)

Needed a simple storage solution that had large capacity, so I took a shot on this drive even with the mixed reviews. It did take quite a long time to move the hundreds of video files onto the drive when I got it, but most of the files played perfectly well. However, as I added more files to it over time, the newer files worked less and less often as well as working immediately after being added but then no longer working. Overall, there is just something bizarrely wrong with something in this technology.Details of my experience (your use case will undoubtedly be different, but understanding what I saw may help you with your own issues using this drive):Basically, utilizing multiple players (including ones from Microsoft and VLC) I tried open the files only to have them not open or get messages about file corruption. To try to correct this problem, I did a deep dive and found an indicator of whether my video file would open was whether there was a "length" associated with the file (to see this field you must add it to the view of the folder). So, I then deleted all of the files with "null lengths" (ie nothing listed instead of an actual amount of time) and recopied all of those from my computer.After copying, most of those new versions of the files had values in the length field and they all opened up but some still didn't. I then started copying the files that still had no value over one at a time. Files that were under 100mb rarely had problems working after being copied and had lengths associated with them. Larger files would copy over but wouldn't work (again, null value in length field), usually this would coincide with speed of the copy going to zero at some point during the procedure. However, through pure luck and persistence I was able to eventually get all of my files onto the drive and working... at least for a moment.So, basically, I spent an entire night copying and getting all of the files, except for the largest two dozen or so, being able to be played through VLC and/or Windows Media Player. The next day, I sat down and again spent a decent amount of time trying again and again to get them to copy over before eventually being successful. I was really happy when the last one populated the length field as seen through Windows Explorer on Windows 10.However, that happiness literally last about 12 seconds as I scrolled down from the final ones I had just done to the rest of the drive to find that files that had been tested and worked just that morning no longer worked and were all back to having "null lengths". My reaction was "WTF?" as I scrolled down and then back up to notice that the same thing was now true for those final ones that minutes earlier had values and worked.If there were bad sectors on this nearly brand new drive (it was only about 3 weeks old at this point), then a file getting corrupted can be expected. However, the issue here seems to be something to do with the way the drive indexes certain files, regardless of their name (part of what I did was change names to shorter versions on some files... and it still would have an issue with that file). There has to be a technical explanation for why this particular hardware has this particular problem but I neither know nor care what that is... Its a damn thumb drive, it just needs to work and this one doesn't.So why are the reviews so mixed? It seems simple to me because I would have given this drive a 4 or 5 star rating after my initial copy. Those files seemed to play fine (although I have figure out that some of them actually didn't. even at the beginning) and although the initial copy process took a long time, I figured it was a one-time thing. However, as I noticed the problems actually effected about 1/3 of the files, a review would have been a 2 star review. But, when things copied over and worked for a minute then didn't... I finally dropped it to the 1 star review you are reading. So, my theory is that the 5 star reviews come from people right after using it for the first time and the lower reviews are from people who have actually used it for a while.Do yourself a favor and buy something else.

I am taking my time to warn you. Besides the extreme slow transfer rate (0-17MBps), I can assure everyone & anyone out there that if you place any important item on any of these compact portable thumb drives, you will be heartbroken & furious when down the road you cannot insert this drive into any computer pc and obtain the contents! I have purchased numerous different "thumb drives" (5 of these YSeaWolf 2TB thumb drives) and ALL 5 have failed to be recognized, popup corrupt and HAVE to be re-formatted (losing all information) before working again! This may take 1,2, 3+ weeks from first use and may take loading over 1TB of data etc, but all failed at some point in time. I have a large movie, video, photo collection that I want to preserve and have on several backup media to be sure I don't lose down the road. THESE thumb drives are not your reliable answer! Stick with a well-known brand of "external drive" and NOT "thumb drive" if you want safeguard. I have several older 3-5+ year old Seagate external usb drives that continue to work flawlessly plug in after plug in with NO despairing unrecognizing or corrupt messages. Not to mention I have over 10 different PC machines, at my company, to test different usb ports, onboard drivers, etc to be sure it is not a dirty port or drivers on the machine are corrupt & not recognizing etc etc that the vendor support or technical support will make you jump through in order to shift the blame or responsibility for the poor manufacturing workmanship of "thumb drives". In closing, I will only use such convenient thumb drive(s) for temporarily transferring (NOT SAVING OR BACKING UP/STORING) having still the original file/data.

As expected

So not sure but one was useless and spent a lot of time backing up stuff on it when it crashed and lost all of my work. The other one I just use for daily back up has done ok so far.

Excelente compra!!!!!!. La capacidad de 2TB da de sobra para la finalidad que lo adquirí (guardado de fotos e imágenes) fue reconocido inmediatamente por mi PC y lo he enchufado incluso en mi celular y a través de la conexión OTG fácilmente he pasado contenido a la Flash USB. En resumen.... perfecto!!!!

This is an awesome item. I do machine embroidery and this has enough GB to put ALL of my designs on one usb stick instead of having several lying around. It is more than I will probably ever use. I would recommend this to anyone who does machine embroidery!

I never considered that a USB flash drive could cause such a problem. Instead, I mistakenly thought that a dongle had messed up my USB drive after plugging it into the dongle. I purchased another one of these, only to have the same problem happen AGAIN after I tried to create a new folder on it.What was the problem, you ask?“Error. The file is corrupted or unreadable.”This problem happens every time I create a new folder on these flash drives. The interesting part is that the files that I added BEFORE creating a new folder work fine, but the files that I added AFTER creating a new folder are messed up. I’m afraid to transfer any new files onto my flash drives because I think they’ll get messed up somehow. Obviously, that completely defeats the purpose of using these flash drives at all. I mean, it’s already corrupted some of them! I’m lucky that I placed some of these files on a Cloud drive before I tried to transfer them to my flash drive.I came on here to read the reviews (should’ve done that before), and I found many of the same complaints. Going to return this crud. If Amazon is as obsessed with customer satisfaction as they claim to be, then they need take the product off their website until the seller fixes the problem with this flash drive. Don’t allow them to sell this trash anymore.
