Because of this flakiness files can get corrupted even if the drive don't disconnect.Ī link I want to leave showing that I am not the only case: File transferring/copying over a longer time over USB 3.0 increases chances for the same disconnect as mentioned above. I can play them on loop 24/7 without a hitch. Playing the same files over USB 2.0 connection will not result an any errors. Noted that some files do not crash the drive but may take longer that the video length so if I put it on repeat it will almost always eventually crash. Note that some video file may take longer to crash the drive or even with same file crash time unlikely to be the same every time. When streaming videos from the external through USB 3.0 Event ID 51 may occur follow by a disconnect and very shortly after the drive will reconnect. I can replicate this very reliably one different external drives and both on windows 7 and 8.1. Perhaps when I have the time I will put the effort on a detailed post on USB 3.0.įirst I have to be clear that this is not the same issue as when Windows 8.1 first came out although the symptoms seem very similar. This is going a bit off topic but I suppose it will be the real fix to all this. Hashing the file before and after transfer would be the obvious option, though it tends to be slow. I suspect the issue would be elsewhere, though. If USB3.0 connections really are reliable, I'll have to look into that. I do not have access to the machine at the moment. I have encounter the same slow transfer speeds with 3rd party software (specifically teracopy) before on a different machine running Windows 8.1 which of course was never resolved. Some suggestions on the matter will be much appreciated! Thanks Of course non of which fixed the problem. I have tried many things, uninstall, reboot, reinstall, use uninstaller such as IObit to remove registries and leftover files, more reboot, virus scan, malware scan etc etc. Reinstalled Extremecopy and got it to work this time but I was still presented with the same slow copying as with the other two.Īll the while windows explorer copier was going to at full speed as it have always done so. Tried out fastcopy and got similar results. it took twice as long on the same job, I was time as well not just looking at the meter). THEN somehow not much later (in the same day) teracopy was going at half the speed (i.e. Tested teracopy again and got the same "good" results as before. Extremecopy was giving some error for the same job so I uninstalled it. However windows default can do the same at ~160Mb/s so I tried other ones as well to see if I can get better results. I tried teracopy first and it worked quite well with ~130Mb/s copy speed. I search for an alternative I've come to the conclusion that the best way for me to avoid file corruption during copy and transfer due to connection issues is to use a file copy program with integrity verification. In the unsuccessful search for the solution to unreliable USB 3.0 connections (tested on multiple drives and computers), I have decided to let it go for now since I didn't want to waste anymore time.
