New subject: [trinity-users] New Thread: USB Hard drive not being recognized after first plug out.

  Hi Guys, 
...
  Probably nothing to do with this problem, but anyway:

 If I have a HDD connected via a USB adaptor, I've found that after an 
 initial plugging and use, then safely removing it, going back to it, 
 in the same session, it may or may not be recognised.  Doing a hard 
 reboot seems to clear what ever causes this.  Simply logging out and 
 logging back in doesn't seem to work.

 --------------------------------------------------------------------- I've seen
this before. Sometimes it just helps to plug out the unit out and do 
the following.

If you can, power it down, then connect it, power it back up.
If it works, it's like the unit. If it doesn't, then it's software.

Another thing  you can try is to wait for a few mins, until the drive spins 
up, plug it out, wait 10s plug in again.

It could be the drive is really slow to spin up.

Good luck, let us know what happens.
