Dear NooNoo, thanks for your quick reply

The HD (MAxtor) drive letter was J:
I have C:, D:
and E, F,G ---> DVD Writer, DVD, CD Writer
and H: logical partition
and the J: was the new HD.

I changed them to C, D, E System and logical partitions.
X, Y, Z for DVD Writer, DVD, CD Writer
the drive got disappeared

so i changed the CD/DVD drives to F,G,H.

So my current naming is C,D,E for internal system and logical drives
and F,G, H for DVD Writer, DVD, CD Writer
-------------------
when i run the USBDLM it gives me that there are no drives connected to the USB, so it doesn't see the drive at all.
-------------------
I use the hard drive for storage since i have internal hard drive with 80 GB and i already had loads of DVDs and CDs so that was some how live storage and expansion to the system storage.
--------------------
Another thing i just noticed when i start the computer after this problem with the HD plugged the computer frees until i unblog the HD - some times it give USB failed to initialize error - and some times not and it continues normally.
