i got a 2.5 external subsystem and the usb input (2.0) sort of fell off and stuck inside and i wonder if it is fixable or not?and whether when it is fix it will still have my work on it?
As you have not got an answer try reposting with a description of what you mean by '2.5 subsystem'? Plus manufacturer and model. If people know what it is they may be able to help.
