Hello,
Thanks. I know the Moore law very well: I was researcher in computers, recently retired.
I don't have a lot of my music files on this disk. I have a dedicated directory on an other disk.
The space is filled with PGMusic programs (since many years, I've written it).
I'm not really angry: I want to know exactly what the "cleaning" function is really doing. Maybe, it's OK and it will fit for me.
But I don't know what will be erased. That's the problem.
Yes, I can buy a new USB disk. I probably will do it. But I'm tired to buy new devices because of many reasons except ... music: I've changed my PC for a gamer tower with Win 8.1 64 bits. My external Roland soundcard has no more midi function with their new driver. I will change too my keyboard (15 years old, it's OK), probably for a NS2 or NS3 or Kronos, I don't know yet. It's not easy to choose the good one and during that time, I don't play music!
So, if I could know what this cleaning function is really doing, it would be probably enough for the moment.
Thanks for all.
Best regards.
François
