One more question ...
I rebooted in msdos mode (i have win98se) and typed update so that i can install the J004 firmware.
After i did that the dos screen showed a message "waiting for (something)IRQ ...ms".
I waited for 20 minutes and after that i pressed esc and the whole procedure stopped.
I used discinfo and it shows that i have the J004 version of the firmware.Also the drive still works fine with no problems so far.
Was the procedure i followed for updating the firmware right ?
