Noticed Amiga Freezes (V4 and Firebird)

I noticed that Amiga freezes after certain amount of HD activity. For example, I play an mp3 that is 153 minutes and boom it freezes.
 
  Because it is asking the HDD. If I put the mp3 into the RAM it can do 500 minutes fine. With HDD I have a limit of 153 minutes before it freezes.
 
  I can run 20 minutes in intercession to a total of 153 minutes, then it freezes eventually. It does not matter if the HDD is based on mp3 or opening a Window. Now that I have used the HDD for a total of 153 minutes any other HDD that exceeds that requirement cause system freeze. Changed buffer however, determines how many minutes I can use before freezing. If I increase buffer to 8000 I am limited to 2 minutes only of hard drive usage. If I go smaller buffer, I have a longer minute of usage, but eventually the minutes will be exhausted and freezing is imminent.
 
  What advise to solve this problem? Is there away I can infinite minute?

What is the Max Transfer Rate set on your HD?

OOH! I did not check that. What is the best Max Transfer Rate to allow Amiga to play an mp3 for example for 30 years without freezing?

There is no MP3 size limit on Amiga.
Your system should not freeze ... unless you did something very wrong when formatting your drive!
 
 
Please mind that you need to take care on a few thinks when formatting a harddrive.
 
On Amiga different filesystem are available.
They all have partition size limitation that you need to mind.
Make sure that your partition is not bigger than supported!
 
Also on Amiga you have a MAX_TRANSFER size for each partition that you need to set correctly. If you set a wrong value than you will get random unpredictable errors.

If I fix the max transfer would it mean losing data to make changes take effect?

You can savely change the value.

What value is Max Transfer now?
I would use $1fe00 or $Fe00.
