In general my experience is that hardware is seldom to blame. Note that we're not experts on said tool or rar archives here, maybe you can check if the RAR file is loaded into memory and which kind of archive is used yourself, possibly with help of other SE sites. | |

@MaartenBodewes file only says "RAR archive data, vb8," and the first line of hexdump -C test1.rar is 00000000 52 61 72 21 1a 07 00 ce 99 73 80 00 0d 00 00 00 |Rar!.....s......| @dandavis well, it still needs to check if the password matches the archive

Well, can't you look at the header of the RAR archive? Maybe the GNU file command knows?

| Jul 25, 2016 at 5:31 | comment | added | Wojciech Sidor | I don't really know how to answer that, but I'm using the latest WinRar (5.31) and the archive type is is "RAR" (not "RAR5", which is also available). | |
| Jul 24, 2016 at 23:29 | comment | added | Maarten Bodewes♦ | What's the version of the RAR archive? If it is one of the latest it seems that the passwords are protected by PBKDF2. That function is deliberately slow. | |
