I am new to Unraid and not familiar with the workaround. I have a 4.7 server that has a five 2TB and two 1TB Hard drives of different models and brand and I am trying to copy and move some files from several of my external USB drives.
I was able to move a total of at least 35 gigabytes of files from a certain drive with the use of Teracopy with CRC mode enabled. However, the software has identified several files that did not pass the comparison for the CRC. So I tried to check on these files using md4deep in order to get hashes for md5 for the files that are on the drive and on the array. Surprisingly, I encountered no issues since they all passed the check. I'm thinking that Teracopy may have incorrectly reported that the 4 files have failed the test. It may have bugs that need to be fixed in order to properly qualify the files being moved. If it does have issues identifying errors, this would mean that it may also have underlying issues when moving files.
I'd like to know if anyone has encountered the same issue because this has to be addressed immediately.
Encountering issues in transferring files
Hello Justin.
Please specify what version of TeraCopy you are using. There actually have been some complaints regarding poor performance and other errors in TeraCopy. However, as a long-time user of TeraCopy, I have yet to find any major problems with it. I suggest you try the latest version of TeraCopy (currently at version 2.7) as CRC errors have already been fixed (or so they say) since version 2.1.
If you find that TeraCopy does not suit you, you could try other alternatives such as FastCopy, Supercopier and Utracopier. I am currently using FastCopy as it seems to be the one that is still actively being developed.
Hope this helps!
Encountering issues in transferring files
That problem is normal when using TeraCopy and I also experience it before between my drives. It usually happens when you are moving huge number of files between separate hard drives and storage devices like USB flash drives and external hard drives. I encounter it when moving files but not when copying. In computer, moving and copying are two different actions or tasks.
When you move a file from one folder or drive to another, the file is copied to the new location and deleted from its original location. When you copy a file from one location to another, the file is simply copied to the new location and the original file in the previous location is not deleted.
Since you encounter the problem when moving files, try copying them instead of moving to make it safer for the files. Also, try doing the copying or moving in small amounts instead of selecting the entire contents of the drive.
If the number of files to be copied is so huge, just cancel the moving of the files or folders where the error is encountered then try copying them again.
