I was trying to say that reading HD formatted media is impossible on DD drives. I've misunderstood that Jack was trying to use HD floppy, formatted as DD 880k disks, in this way it works without any problem.

do you guys still use floppys when playing games?

Yes! Through ADF's on WinUAE

JACK98 · 07 January 2009, 20:23

i would use whdload except haven't got clue how to use it.let alone I'm waiting on my cf to come in post so i can transport it to the amiga then.

just got a boxed copy of uridium2. disk 2 looks clean but when i hold it upto the light bulb and hold the slide open i cant see through the disk material. i can with disk 1, a clear red image of the light bulb. is this contamination or were disks made of differing density?

Hi PZ,

Are you serious?

What happens when you try the disks in the floppy drive?

I reckon this should be OK as the disks are clean.

pubzombie · 11 January 2009, 00:17

yes sorry i am serious and a little paranoid, i killed my original 500 drive when i was a kid some how with a disk that looked clean. didnt think it was the floppy as it looked ok so put it in my external drive an it killed that also - never found out what it was but then again i was more interested in the girl next door at the time and my miggy got left to rot.

prowler · 11 January 2009, 00:23

Can you spin the disk in its case by rotating the metal centre with your thumb? And does the shutter open and snap shut OK?

I would say that if the answer is yes in both cases, then it should be OK to dry the disk in the floppy drive without 'killing' it.

JACK98 · 11 January 2009, 01:26

Think best way as suggested was-open the shutter,and with ur finger underneath the floppy.spin the metal part around with your finger.And check for any dirty/fungi.that's what i would do anyway.

Drive heads could had just been covered in shit from floppy.happened me before.lucky i had a disk cleaner nearby and brought my amiga back to life.

I tried to rescue an archive of 5.25'' (from '86-'91) floppies under DOS a year ago. About 50% were mostly ok. Those were the expensive ones. With the noname stuff, I was happy when it still contained the FAT (filenames, structure), so that I could tell what was lost. Some made screeching noises and some didn't rotate at all.
I opened the drive's chassis in order to see what was going on, and I had to clean the magnetic head with alcohol several times.
The drive still works after this often unpleasant procedure.

If you can extrapolate this to 3.5'': With good quality (originals, brands) and a bit of caution you are relatively safe. Forget about the rest.

Maybe you can give it a test run in an inexpensive PC floppy drive? If it doesn't get damaged, then the Amiga's drive will probably survive, too.

Are they files you could find on net?.i had some floppies too.had throw them out do cause floppies had fungi inside.luckily i was able to get the files off the net.

gilgamesh · 11 January 2009, 21:16

I found some of them, Zaxxon for example. Yet most of it was uninteresting or completely gone. I did this for a relative of mine, and I could rescue some of his serious stuff, though.

The problem wasn't fungus, as far as I can tell. It seems rather to be dust, nicotine and a strange aging process in the materials, that somehow made them bake together.

I hope my Amiga floppies are in a better shape. At least I know for sure they were treated with respect.

JACK98 · 11 January 2009, 21:18

Don't know what going to do the day wont be able to get floppies.i even wonder were does amigakit get his floppies from.

pubzombie · 11 January 2009, 23:20

i was listening to a radio program not so long ago about historical archives. Apparently no data is safe. magnetic data degrades relatively easily whether the tapes or disks are high quality or not. according to the programme even cd's and dvd's will degrade with time; nothing will last as long as the good old pen and paper - allegedly.

JACK98 · 11 January 2009, 23:22

yup its true.since cd-r's,dvd'rs and cds themselves are only around recently no one knows their life expectancy.it's the elements too.probably explains how they filter air and moderate temperatures in museums/galleries.

gilgamesh · 11 January 2009, 23:53

Standard (pressed) CD-Roms can last ~50 years. CD-R have the problem of an aging recording layer and oxidation of the silver reflector layer (~5 years). CD-RWs are slightly better due to better gluing. CD-RAM are best for private digital data (~30 years)

If you're interested, google for digital dark age and digital preservation. Wikipedia gives a good intro. That's another interesting aspect of emulators. (see http://www.planets-project.eu/)

EDIT: Microfilm is quite good.
