View Full Version : Getting errors in MKV during USB 3.0 transfer?

Hey all I just got a new external harddrive and it is USB 3.0 I've been using that cord plugged into my laptop, which sucks but my tower died I cannot afford a replacement, (using USB 2.0) to transfer files and I've noticed that I am getting small one second errors in some of my files... :mad: I've switched from a USB 3 to a 2.0 cable and going to try again. I've had errors like this before on my old drives but they have been quite rare every once in a great while (perhaps one out of one hundred) but the last 3 files I've sent to my new drive have had them...

My transfer speeds start out roughly 60Mbs and then decrease to about 20Mbs which is the normal speed my laptop gets on my other External HD (when using USB 2.0) which is USB 2.0/eSATA. Could that initial 60Mbs be the reason that is getting damaged? My Laptop is running 7 Home 64 and its USB ports are set for 'quick removal' so there is no caching because there are several people that my need my laptop so I don't want them to damage any of my drives.

My main questions are:

First is there anyway I can scan a transferred file for errors? They play just fine until the hit the damaged spot, if you skip over it the rest of the it plays fine as well. Remuxing will allow play thru of damaged piece but the video is corrupt. I have about 200Gb on this new drive that I transferred over and checking all those files by watching them all the way thru would take ALOT of time... =(

Second has anyone else had this problem with USB 3.0? or can think of how to prevent this from happening to future files? Can I slow the transfer speed to 25Mbs somehow? I'd rather it take forever then having my files get errors...

I just copied a new file rather then cut & pasted so I will try the one on the external first and compare it to the original. That way I should be able to know for sure that its the transfer creating the errors.

Yep, that's the easiest way. You can use fsum frontend (http://fsumfe.sourceforge.net/) or similar for that.

I also use a USB 3.0 HDD and don't have any problems, btw. (Speed between 70 and 110 MB/sek) I wouldn't focus too hard on the very USB transfer, though. Could be that your internal controllers, hard drives, RAM etc. produce the error. Also test those (run MEMTEST, copy on your local drive )
