OS 9 - doesn't recognize flash drive

Did you format it HFS+ and install OS9 Drivers?

Something like Disk Utility on OS9... run that, sorry, sick & drawing a lot of blanks right now.

I'm not sure Drive Setup (OS9 equivalent) of DU can handle this. As I recall, flash drives do not show up as drives in the proper sense in OS9. A flash drive behaves more like a floppy disk. Usually when I wanted to format a flash drive in OS9 I would click on the drive and erase it. The computer would ask me what format and then reformat it. This doesn't really address why yours isn't showing up at all on your OS9 machine but I think you might be better off doing this in OSX.

Thanks, I think you're right. 🙂

I just did a quick check:
Finder says the flash is a network volume and you can't erase it. Disk setup reports the volume as unsupported.

Julia,
open control panel "extensions on/off" and check that all Apple extensions are active. There should be several extensions dealing with USB. It might also help to upgrade your OS to 9.2.2 in case you got 9.2.1.

You wouldn't have Hard Disk SpeedTools™ 3.1.1, or Norton on your OS9 would you?

Hi, Julia. USB 1.1 and 2.0 flash drives are supported by all Mac OS versions from 8.1 on, though USB 2.0 drives will only operate at 1.1 speed in any OS earlier than 10.2.6. So I suspect that, as others have suggested, you are missing or have deactivated the necessary USB extensions on your iMac.

You should have the following USB extensions present and activated in Extensions Manager (shown below with their version numbers) if your iMac is running OS 9.2.2:

USB Authoring Support 1.1.2
USB Device Extension 1.5.6
USB Mass Storage Support 2.1.1
USB Printer Sharing 1.0.2
USB Printer Sharing Extension 1.0.2
USB Software Locator 1.5.6
USB Support 1.5.5

Not all of these are essential for flash drive support, but USB Mass Storage Support definitely is, and some of the others may be.

If you still have trouble using the flash drive, you could network the two computers. You will need a ethernet crossover cable. no router needed. Plug the cable into the ethernet ports on both machines. With the proper network setting, you should have easy access to either machine. I have a beige
G3 os9 hooked to an imac osX this way. tom

Julia,

suggest you download and apply the OS 9.2.2 download.

It will add any missing extensions of your system.

You are welcome. Glad I could help.

Tom... I've tried to find info on how to troubleshoot OS 9 and OS X networking via an ethernet crossover cable, and can't.

Since you mentioned that in this thread, I'm wondering if you could help point me in the right direction?

Thanks!

Probably would be better to start a new topic on this since your goals and configurations are different. In the meantime [Creating a small Ethernet network|http://docs.info.apple.com/article.html?artnum=106658]
