System freeze due to Jazz

Hello!
   I have a Toshiba Laptop and a Jazz driver which is pretty new, and which is always connected.
When I open up my laptop and the computer attempts to read something from the Jazz drive, the computer freezes.

For the moment I am having to shut-down my computer every time, which is a pain! So how do I prevent my laptop
from freezing ?

PS: Note that I always turn on the Jazz and insert the cartridge and let it load before I open the laptop lid.

Did this just start happening? What operating system do you have, i.e., Windows 95?
Have ever had any problems before with it?


Thanks,
Mike

I'm using Windows 95. There are no major problems with the Toshiba, nor minor problems.

I think it never worked actually...Can it work? Or do I have to start up every time?

Check in your documentation for the laptop and see how to see your parrallel port to either compatible or EPP/ECP mode or bidirectional. Set it to EPP/ECP if not set at that and try it again and let me know what happens.

Thanks,
Mike

Tried that-didn't work. I need it to be on Standard bi-directional for my printer anyway or my printer won't work!

Have you tried uninstalling the drivers and reinstalling them to see if that worked?

Thanks,

When you start the system do you see the led on the Jaz blink (even when the system freezes ?). Are you using the WINGUEST program of Iomega ?, or have you tried loading the disk after Windows was started ?.

The drivers are installed correctly (I'm almost sure!)...everything works fine, except for this resume problem with the Jazz.

There is absolutely NO Jazz activity when I just open up the computer. (ps: opening up=opening the lid and resuming from where I started..)

It sounds like you're having an IRQ conflict. Go to System Properties > Device Manager and check your Jazz and Printer(s) device properties. Examine the Resources of these devices for conflicts. If a device does have a conflict with anther device, I suggest (only if you feel comfortable doing so) unchecking the "use automatic settings" box and changing the settings; do so with the other device as well. You may want to record the original settings just in case you want to restore them.

Also, you may want to disable any unused com/printer ports.

Check for any conflict in Device Manager. If there's one or more, just Shut Down the system, then Reboot in SAFE MODE (by pressing F8, then option 3).
Go to Device Manager again, and Remove all Conflicted Devices. Reboot the system.

No. I don't think it's a port problem. The Jazz is connected through the PCMCIA SCSI slot. No conflicts on that. The Iomega Jaz card Host adapter (SCSI Controller) is also working fine with no conflicts. There is a Generic IRDA compatible Device' in the Ports (COM&LPT) section, which Windows95 automatically installs if I remove it. (although I've always seen it with a red cross through it. No conflicts there either.

I think maybe the problem doesn't lie in here...

Are you saying that it has trouble reading the Jaz drive after coming back from suspend mode?  Does it come up okay from a cold boot?

Remember that suspend mode is NOT the same as turning it off, and turning off the Jaz while the laptop is in suspend mode may confuse it, as the Jaz drive isn't hot-pluggable, and won't be recognized when turned on after the machine has booted up.  Try leaving the Jaz drive ON when going into suspend mode.  You shouldn't have a problem then.

Ok....that might be a good explanation of what is going on here. What is hot-pluggable ?
Is there a way of making it hot-pluggable ?  

How do I do a cold boot ?
Is that like safe mode, because I don't think the Jazz will work in safe mode anyway. It needs a PCMI extension to run.

Sure it works. But it doesn't work when resuming/suspending.

Also check Toshiba's site, I've often had problems with operable but outdated drivers for the SCSI controller.

I have updated the Iomega Tools from 5.1 to 5.2
The problem is still persistent. (Even when I "leave the Jaz on")

   I ....don't think there are any SCSI updates needed for my Toshiba Satellite Pro 420CDS

  Toshiba had no info on SCSI or Jaz anyway.

  still unhappy :(

This might be going to extremes, but there is a BIOS V5.30 download for your model.  Is that the version you've got?

There is a CardWiz update (CWINFFIX.EXE), but it says for cards that aren't initializing, while yours is just on resume.  Have you tried calling them to see if they have any info on resume problems with that model?

updated BIOS from 5.2 to 5.3  ---  still no change.

No known problems. COuld it be some kind of software conflict with other PCMIA software?
