Why a brute-force attack on RAR3-HP hash fails?

Hello and a special hello to hashcat.net's regulars.

This is what I've been trying to do and I don't know why it's not working:

Code:

$ cat my.hash foo.rar:$RAR3$*0*_REDACTED_*_REDACTED_:0::::foo.rar $ hashcat -a 3 -m 12500 ./my.hash ?l?u?d? hashcat (v4.1.0) starting... * Device #1: Not a native Intel OpenCL runtime. Expect massive speed loss.     You can use --force to override, but do not report related errors. * Device #2: This hardware has outdated CUDA compute capability (2.1).     For modern OpenCL performance, upgrade to hardware that supports     CUDA compute capability version 5.0 (Maxwell) or higher. * Device #2: WARNING! Kernel exec timeout is not disabled.     This may cause "CL_OUT_OF_RESOURCES" or related errors.     To disable the timeout, see: https://hashcat.net/q/timeoutpatch nvmlDeviceGetCurrPcieLinkWidth(): Not Supported nvmlDeviceGetClockInfo(): Not Supported nvmlDeviceGetClockInfo(): Not Supported nvmlDeviceGetTemperatureThreshold(): Not Supported nvmlDeviceGetTemperatureThreshold(): Not Supported nvmlDeviceGetUtilizationRates(): Not Supported OpenCL Platform #1: The pocl project ==================================== * Device #1: pthread-Intel(R) Core(TM) i7 CPU      870  @ 2.93GHz, skipped.

Any suggestions/ideas?

The hash format can be double-checked by looking at this page https://hashcat.net/wiki/example_hashes or with hashcat itself e.g. hashcat -m 12500 --example-hashes

The hash format should not contain the file/path part. You need to provide the raw hash (without file names). Please always try to run/crack the example hash if you have problems like this. Your target hashes should be similar to the example hash.
