Error creating dump file

When I run the command  hf mf dump I get an error message and no output file is written

I have all my keys:

After a few tries with the read sector command, I can read each sector

proxmark3> hf mf rdsc 0 A FFFFFFFFFFFF
--sector no:0 key type:A key:ff ff ff ff ff ff

#db# Authentication failed. Error card response.
#db# Auth error

Could I have a bad proxmark?

Can I create the output file manually? I would manually read each sector then copy/paste it in the notepad editor.  What would be the format of this file and how would it be organized?

As a check:

Re: Error creating dump file

Could be antenna, run and paste yr output.

 hw tune 

It could also be the positioning of tag and antenna, usually 1-1.5cm is a good distance.  trial and error to find the sweet spot.

Not sure why u use "ekeyprn".

Read the datasheet for mifare classic to see the memory layout.

Re: Error creating dump file

Thanks iceman.

here is my ant details

proxmark3> hw tune

Measuring antenna characteristics, please wait........
# LF antenna: 31.21 V @   125.00 kHz
# LF antenna: 29.15 V @   134.00 kHz
# LF optimal: 36.16 V @   129.03 kHz
# HF antenna: 28.50 V @    13.56 MHz
Displaying LF tuning graph. Divisor 89 is 134khz, 95 is 125khz.

Re: Error creating dump file

Got it to work.

1. removed lf ant
2. held it a small distance from the reader.

thanks iceman for your help

Re: Error creating dump file

You should not have to remove the lf antenna,  well, there are posts about the pm3 version from Elechouse, "pm3 easy".
