Help dumping Novell Netware 2.15 Gendata floppy

[robbo007]

Hi all,
I've aquired a couple of 8bit network cards and a load of Novell and Gateway Communications Inc. Floppies for Netware 2.15.

The Advanced Netware Gendata disk works and appears to be good but when I dump using these commands I get a load of bad secotrs which looks like copyprotection maybe?

dtc -f"%DTC_GameTitle%[%DTC_Platform%]\%DTC_GameTitle%%DTC_PlatformFileName%(%DTC_CurrentDisk%of%DTC_NumberOfDisks%)" -i0 -i2 -v300 -d%DTC_DumpDrive% -f"%DTC_GameTitle%[%DTC_Platform%]\%DTC_GameTitle%%DTC_PlatformFileName%(%DTC_CurrentDisk%of%DTC_NumberOfDisks%)".img -k2 -i4

I've tried to write the disk back to a new floppy and its not readable. Any help most appreciated.

Heres the dump log:

[SomeGuy]

I could be wrong, but it is my understanding that Netware 2.15 used hardware key based copy protection, not disk based copy protection.

The above log shows 9 sectors per track with seemingly random numbers of bad sectors on a number of tracks. That does not look like copy protection to me. Looking at the histogram (or loading in to HxC and looking for red areas) would show "noise" if there is a real reading problem rather than copy protection.

If it seems to work on your DOS based system, try dumping it with ImageDisk. If that works then you will at least have the data in case the disk is getting worse.

There are a few things that might cause it to read OK on one system but not another.

Is this a 3.5" 720k disk?

I'm seeing 9 sectors and 80 tracks, but the RPM value says 360 RPM when it should be 300RPM for a normal 720k 3.5" disk.

If you are using a "Mode 3" compatible 3.5" drive, make absolutly sure the density line logic level is set right. Typically you must select Density Line High in the Kryoflux menu to indicate you are using a low density disk. (Yea, logic level is the opposite of the density).

Mode 3 drives (used in the Japanese markets to emulate 8" disks) enter 360RPM when the asserted logic line does not match the notch on the disk. Most 3.5" drives just ignore the density logic line. A few actually flip density filtering based on the logic line.

Thanks SomeGuy, Great replies as always.

So I'm using a 1.2MB Teac floppy drive and the floppy is a 360kb. I'm using the -v300 parameter.

I've just Winimaged the floppy and as you say, at least I have the data. But it would be good to see what's going on the the errors.

Thanks,
Rob

[robbo007]

Do you think ImageDisk is more accurate than Winimage? and better to use for these cases?

http://www.classiccmp.org/dunfield/img/index.htm

[SomeGuy]

ImageDisk is typically the prefered tool under DOS. Winimage is the prefered tool under Windows. I did not know if you had Windows on it. ImageDisk is better at imaging DOS 1.x formatted disks and some non-DOS disks, but that should not be an issue in this case. Be sure to write protected you disk.

[ZrX]

If possible, upload the raw files of the dump to sendspace/gdrive/etc. and someone usually can quickly check the dump and find the possible cause for the error.

[robbo007]

Ok, Here's the link: https://drive.google.com/file/d/1Sc_i-5 ... sp=sharing

[ZrX]

Either there's something wrong with the drive (dirt in the bottom head... do other disks read ok?), or the disk itself.

About 1/3 from the beginning of the bottom side (side 0) tracks of the disk is just noise, which then gradually is becoming readable towards the inner tracks.

Top side (side 1) is in moderately good condition.

[robbo007]

From all these Gateway Communications G/net Netware disks, I've got 3 which I can't dump. That was one of them. The others seem worse but I can image them using ImageDisk (with errors). The rest are fine. I've been cleaning my drive too. So not a dirty drive. Must be the disks. Good to know I'm going the dumps fine.

What I have seen are a few videos on youtube about floppy disk cleaning with isopropyl alcohol (IPA 99%). Is this a good idea? Or will it damage the floppy disks?

[SomeGuy]

Isopropyl alcohol can damage low quality, shedding, or scratched disks. If you have used Isopropyl alcohol to remove paint or rust... well, guess what is on the surface of that disk. (rust filled paint!).

But higher quality disks can withstand it, and sometimes that is the only way to get really bad sticky gunk off.

Also, I would not recommend anything stronger than 91%.

Typically, I recommend just starting with hot water. With 5.25" disks you can just run water in around the hub. That gets damaging gunk off the disk and out of the jacket lining. Then I use a couple of q-tips to gently prop up part of the hub and put in front of a fan to let it dry. Periodically adjust the q-tips to help prevent the disks jacket lining from sticking to the disk as it dries.
