|I need some advice, and I'm SURE this is the best place to get it!

|About a week ago, I purchased an external Amiga 3.5" drive, labelled as
|the "AIR products A1010 External Drive."  This drive is supposed to be
|superior to the C-A drive and the Pro-drive in several respects:  first,
|it uses HALF the power normally required for an external drive; second, it
|has the port in the back for pass-thru; and third, it is small and quiet. :-)
|
|Needless to say, I was excited to get it.  BUT, after connecting it to my
|system, it started to do very strange things.  For example, I warm booted

|This is the problem...  it does this with everything I put in df1:.  I'll
|either get a requestor like the one above, or I'll get a requestor telling
|me that my disk is corrupt.  I tried it with the WB Initialize on the
|pull-down, and it informed me that every disk I had was bad.  df0:
|initialized them all just fine.
|
|Now for the kicker... I hooked the drive up to an A1000 (mine is an A500)
|and it worked perfectly.  When I got home, I removed my Progressive
                                              ^^^^^^^
|Peripherals .5M card, and the drive worked perfectly on MY system!?!?!
|
|I have concluded it is a power problem.  But what I can't determine is
                          ^^^^^^^^^^^^^
YES, you got it!

|whether it is in the memory expansion or in the power supply for the A500.
|Does anyone have any comments on either the PP512k or the power supply
|that might help me solve this dilemma?  

The A500 has enough juice to drive EITHER the external disk OR the PP512K,
but not both at the same time.  Get a power supply with more juice.

When using the Commodore .5M expansion + Commodore's external drive, the A500
works just fine, which means that the PP512K + AIR external drive drain
more power than Commodore's units.
