Very Computer

Hello all,
I have bought an Solid State Disk (SSD) with 64MByte (Hamlet Exagerate).
It works nicely on MacOS 9.2 and diverse WindowsX systems.

I have found out how to mount (mount /dev/sda1 /mnt/pendisk). I
supposed that also umount should work.

I unmounted, waited for flashing of the control light to stop, and detached
physically the device. I then attached it again and tried to remount it,
but I get the error: No medium found.

Any idea?

Thanks a lot and have a nice day,

Provide us with the output from "dmesg | tail -40" after you tried this,
and somebody will have an idea.  There's too little information in what
you provided to do more than guess, but the kernel will have logged
a bunch of useful information including any errors.

Right.
I have found out about "eject".... in the meantime.
BUT ...
Actual situation:
Machine reboot.
attach device
mount /dev/sda1 /mnt/pendisk (OK)
umount /mnt/pendisk (OK)
eject /dev/sda1 (OK)
detach device

After a while
attach device
mount /dev/sda1 /mnt/pendisk (OK)
umount /mnt/pendisk (OK)
eject /dev/sda1 (OK)
detach device

This works fine for three times, then I get

mount: No medium found

Here is dmesg:

Flashlight flashed steady now when I attach the device, but does not flash
fast at any further trial.

Any suggestion?
How can I "reset" the usb driver or bus? Only reboot will help?

Thanks a lot,
Best regards,
Igor
