Title: [Solved] Iomega ZIP 100 IDE
Post by: Igor on December 30, 2021, 10:48:35 pm
I have iomega zip 100 with IDE interface. I want to access the disk.
I installed an additional IDE controller and drivers:

Code: [Select]
BASEDEV=DANIS506.ADD /!BIOS /A:0 /BM /U:0 /A:1 /I /V
BASEDEV=OS2AHCI.ADD
BASEDEV=DANIATAP.FLT /A:0 /U:0 /TYPE:Z /EJ /V

The system is successfully loaded.
I get a report:

Code: [Select]
R1.8.15      /!BIOS /A:0 /BM /U:0 /A:1 /I /V
            Daniela's Bus Master IDE Driver for OS/2 Version 1.8.15
Controller:0  Port:D020 IRQ:10  Status:OK
  JMicron JMB363 PATA host (197B:2363 rev:03) on PCI 2:0.0#1
 Unit:0 Status:OK ATAPI PIO0
  Model:IOMEGA  ZIP 100       ATAPI             14.A   

And

Code: [Select]
0/m: IOMEGA  ZIP 100       ATAPI              14.A    b                     
Port D020/D012, Irq 16, ATAPI, PIO0

0/s: (not present)

However, the drive letter in the system is not assigned and contact the device cannot be applied.

What can be done to get a drive letter in the system?
According to my memories, once a long time, this device worked in the OS / 2 system.

I am guessing, that you need to mount a disk, and use LVM to assign a drive letter (same as required by USB sticks). That would need to be done for every disk, if it is actually the answer.

Thank you for the response. LVM does not allow you to create a volume on the disk, although the disk itself sees. Similarly, it displays flash drives that are missing. Of course, the drive in the drive is pre-inserted.

I used those back in the day. I remember that the hardware doesn't last long.

Only DaniS506 and DaniATAPI are needed, and no special command flags were needed, but that was when DaniS506 handled the hard drives. Now with OS2AHCI, there is more complexity. You've shown that the controller is loaded.

Did you mention the master/slave status of the Zip drive?

I made some notes, but they are from long ago: http://www.blondeguy.com/ZipInstallEssay.html (http://www.blondeguy.com/ZipInstallEssay.html)

I installed this old Daniel driver. It did not help. The driver used by me for several years is newer and there is a disk icon in LVM, but it is supposedly not inserted.

I seem to vaguely remember that with newer versions of DANIS506.ADD the DANIATAP.FLT is no longer needed.
What also seems odd that one driver reports use of IRQ 10 and the other of IRQ 16 for the very same controller. Just try without the FLT driver.

Igor,

I have an IDE Zip disk on an eComStation machine.  The motherboard does not have an IDE interface so I am using an expansion card with an IDE interface.  I have attached my config.sys in hopes it might be helpful.  I do not remember making any changes to my config.sys in order for the drive, or expansion card, to work - but it was a few years ago.

Zip disks function like USB thumb drives, in that a drive letter is not assigned until you insert a disk and click on Refresh Removable Media.  Likewise you need to "eject" the disk using the command line or the WPS before removing the disk.

I have about 10 zip disks from the mid 1990s that I recently searched looking for some old software.  All the disks were readable.  Most are formatted as FAT but at least one is formatted HPFS.

My memory of how I formatted some as HPFS was to insert the disk before booting the machine; the system thought it was a fixed drive at that point.  Once again this was many years ago and I may be remembering incorrectly and that might have been on a SCSI based Zip drive - if it makes a difference.

Good luck

If you remove the Daniatapi, the disk icon in the minijm disappears.
Error with interrupts is a well-known Daniel error. There in one case does not correctly display interrupts if their number is more 15.

Just guessing out of nowhere, based on my own IDE-ZIP100 memories with DOS:

Did you try booting the machine with a ZIP diskette in the drive?
I remember, DOS never gave a letter to the drive, but the diskette, when using the IDE ZIP100 drive.

Perhaps it's the same with OS/2. Leave the disk inserted, and restart. - Does it have a drive letter now?

The USB ZIP100 however, does indeed still assign you a drive letter, when inserting a diskette while the operating system is already fully booted.

I tried to download the operating system having a diskette in the drive. This does not result.
I changed the definition of the device as a floppy disk. It did not help, and I recognize that the drive may simply spoil during this time. Until now, I have no opportunity to check the device's performance. And will this opportunity arise - it is not known.

This may be a stupid idea but... your zip drive has a full ide interface so you could try attaching it to an IDE to USB adapter and see what the response is.  I have used IDE to USB and SATA to USB adapters to read disks that won't attach to the onboard interfaces.

Simplest is probably the DFSee stick downloadable at https://dfsee.com/dfsee/media.php (https://dfsee.com/dfsee/media.php)
Whether that has support for the Iomega zip drive, I don't know.
Title: Re: Iomega ZIP 100 IDE
Post by: Igor on November 13, 2022, 09:53:58 pm
Solved!

1. Install ZIP100 as a hard drive (not like a floppy disk).
2. Install Danis driver:
BASEDEV=DANIS506.ADD /!BIOS /A:1 /I /V
BASEDEV=DANIATAP.FLT /EJ /V
3. After installing the disk in the wildcard, use the LVM command - lvm /rediscoverprm
4. A disk letter will appear and you can work with it
5. Before extracting the disk, use the command - eject drive:

Thank you all for participating in solving the problem!

When I insert a zip disk, and refresh removable media, no drive letter appears.

Unfortunately, my ZIP drive is not working stably. There was one hardware configuration (controller, interrupts) in which I managed to make it work.
But alas, I updated the system on ArcaOS and everything stopped working. I opened a ticket, but no one could help me.
I have an assumption that the device letter assignment is incorrect when the disk is inserted. It worked for me in the ecs system when clicking on the USB device update icon (crazy). It doesn't work in any way at the moment.

I guess each disk will need partitioning and have LVM info added

I guess I don't see how to add LVM information. The disk doesn't seem to show up.

Not quite true, there is an inaccessible ghost disk in LVMGUI that has the right size.

I tested this idea. Unfortunately, Chinese converters do not know how to work correctly with AHCI (controller on the motherboard). If you use a separate controller and DANIS, then nothing fundamentally changes.

Hi

The 3 "fake disks" are probably related to the USBMSD.ADD  /REMOVABLES:  value  in the config.sys file.  What value are you using?

Hi Pete,

I don't see this as a problem. I have installed /REMOVABLES:2 - this is 2 disks. Another one is either a USB CDrom or a blank for ZIP 100. But the trouble is that when the floppy disk is inserted, this blank is not filled with real media data.

A floppy disk will never show up under LVM. And LVM will only show dummy units for whatever is specified via the /REMOVABLES switch.

Hi Lars,

Will this be the case even if the ZIP drive is connected to the IDE bus?
I see in my message similar to the truth figures (96) regarding the capacity of the disk...
Title: Re: [Solved] Iomega ZIP 100 IDE
Post by: Lars on May 14, 2023, 01:27:44 am
If it is connected to IDE, it is served by DANIS506.ADD and it should show under LVM. But the 96 MB entries are typically dummy entries, stemming from USBMSD.ADD.
If a ZIP disk is inserted already on boot, it should even be locked in the drive. I forgot what to expect if it is inserted after boot.

If the ZIP disk shows up in minilvm (and that seems to be the case) and if a disk is actually inserted, you should be able to create a volume on it. Once that is done, you can leave minilvm and do LVM /rediscoverprm and it should give you a drive letter (maybe only on next boot, can't remember). You should then be able to format the volume.
At least that is how it worked with my parallel port attached ZIP served by PPAOS2.ADD.

I would think so, but LVM says the drive is inaccessible, and MiniLVM seems to agree. It shows the little cloud and does not give the option. I think the actual zip disk is formatted HPFS.

Back in the day, DaniS506.ADD didn't need any parameters to access a Zip disk. I wonder what the !BIOS flag does?

Hi all,

I checked and in my case 3 empty disks are blanks for USB. If you remove from config.sys сorresponding lines, then these blanks disappear from the system.
However, I never got access to the ZIP drive. And it is not visible in lvm. Although Danis506/danisflt recognizes it.

From the documentation,
Code: [Select]
     /!BIOS                                                 (call BIOS
        Disable all BIOS Int13 calls                           if required)

Could always test without it.
I also see under Unit options,
Code: [Select]
     /!RMV                                                  (device default)
        (not) removable media drive
So perhaps need /RMV for the zip unit?

Has anyone of you ever tried to access the drive with DFSEE?
DFSEE will be able to access the drive even if the OS does not assign a drive letter.
I am led to believe that you need to add LVM info to the volume(s) as LVM did not exist 20 some years ago.
Once that is done, the drive (or rather, the volumes) should show up with drive letter(s).
A brutal way to start from scratch is to have DFSEE wipe the first 63 sectors (or more) with zeros but of course that will lead to complete loss of data on that ZIP disk.

I tried DFSee, but DFSee does not see the drive at all. LVM can see the drive, but no operation actually works. I tried renaming the drive, and it says it worked, but when I open it again in LVM, the original lack of disk name appears.

MiniLVM shows an extra unavailable drive with the right size, but no operation is allowed.

I found a USB zip drive and hoked it to an ArcaOS 5.1 beta system. Everything seems to work. I can verify that my zip disks are working. I used this system to assign a drive letter to the disk.

Back on the IDE Zip drive system, the disk with LVM information does not appear. Adding a drive letter does not seem to help.

Wasn't there a kink with the IDE ZIP drives? Did they not show some strange behaviour if they were set up as busmasters, especially with some chipsets? It's been 25 years, but I gave up on IDE ZIP's altogether for some such reason and only used SCSI versions.

I can vaguely recall setting it up for friends a few years later that the most successful setup was having them as a slave on IDE channel 2, with the caveat that most MB's post 2005 only have one IDE channel ...

I understood the reason and solved the problem of unstable IOMEGA ZIP 100.
It's all about an unsuccessful design. Magnetic powder flies from the disk to the printed circuit board and forms random connections.
In my case, it helped to remove dust from the printed circuit board of the device.
Unfortunately, I admit that in some cases, random compounds can cause damage to electronic components or the logic of the drive and physical damage of disks.
