Cleaning A500 DISK DRIVE

[zonaps2]

My disk drive sometimes doesn't work, It tries to read but fails sometimes, the I just blow into the unit and it works again.
I have a old cleaning diskette in great condition but missing the liquid that come with it. What can I use? Isopropylic alcohol would be fine?

Thanks.

Ok, I'll check the cable.

Thanks for replying.
How do I use that head cleaner program?
what kind of file is .lha?
I need to burn it to an Amiga disk?

Thanks

I own an A500 since 1990, but never had a HD, so I guess that's why I'm not familiar with Amiga extension files.

Thanks for advices :-)

But I'm not understand how to unpack the .lha to an amiga floppy.
Do I have to unpack using my pc disk drive and that's all?
I mean, the disk must be amiga formatted right?
Pc will be able to write an amiga floppy?
and Amiga will be able to read it?

Sorry but I don't get it!

Thanks

Ok, I'll try that.
