Why I files when adding to the archive 7z, WinRar?
Half experiment, I can not understand the reasons.
Archive a virtual machine image, which is installed Win10. Beating the first big file (vmdk), weighing 3.5 gig. A total volume of 9 gig. The file is compressed with NTFS on NTFS partition, I tried to transfer files to another hard drive.
Windows 7 Pro x64, 7z, 16.04 x64, WinRar x64 5.50.
RAM 8 gig system stability, not really complaining, though ponapihano protective soft order.
In any case - almost all terms during a check of the archive CRC error.
Create an archive with maximum compression in 7z (LZMA). Check the CRC error.
Create RAR5 archive with maximum compression or plain - error CRC.
Squeeze ZIP from the same 7-zip file manager with minimal compression - all fine.
The compression process takes about half an hour.
Otherwise, the computer itself does not a bad show, but duplicate (multiple times) error on the same operation.
