Title: Floppy Pain In The Butt Problem
Post by: Dr_Righteous on April 29, 2003, 01:28:30 PM

First, I'll start with my specs... A4000D, 040/25MHz (with FPU), 2M Chip, 16M Fast, 8M Ext (GVP A400 SCSI board), 2x 1.2G IDE drives (DH0, 1,  2), 4G SCSI drive (DH3), 4-Speed SCSI CDROM, WB ver 3.9... Pretty standard stuff.

The problem I'm having is kinda strange. Every now and then, my system reads my floppy drive for no apearant reason. Ordinarilly this isn't a problem, but whenever I try to restore an ADF to a disk, I have to do it several times because this read cycle interferes with both Tacktool and DiskWiz.

I've yanked all my WB enhancements out, even disabled CrossDos, and still have this problem.

Anyone have any ideas?

Um, memory resident virus trying to write to floppy boot blocks.

But of course you've checked that, haven't you ?  ;-)

Schtop! That's not the correct interface you're using!

I think the hospital A&E department will give you some strange looks :-)

Could it be simply that the floppy disk controller is knackered?

Of course not... Why would there be any viruses written for the Amiga?

LOL

No, there's no viruses... At least none VirusZ is picking up...

I had much the same problem on my A2000. Because it lives in my bedroom and runs 24/7 the FDD reads would even wake me up.

Turned out to be a suspect diskinsert switch. A quick spray with CRC contact cleaner (possibly available where you live) was enough to fix it for a few months.
Eventually the switch itself gave up though, so I simply replaced the 880k FDD with one from an A500. Took some work to swap the casings, and not all A500 FDDs are the same, but it did work.

I'd suggect pulling the drive down and testing the diskinsert switch with an ohm meter.
