Hello

Running a net6501-70 board in its rackmount case (with the included
internal power supply), I'm having troubles with SATA-II disks (Samsung
HN-M101MBB, which actually seem to be Seagate ST1000LM024; attached to
J1, J2, JP18): almost always at least one of the disks fails to spin up,
producing a tapping noise for a second instead of the usual spin-up
noise.  But sometimes both disks succeed to spin up, and sometimes both
fail.

Attaching only one of the two disks to one of the SATA ports, spin-up
also fails most of the time.

However, if the disks are _not_ connected to the SATA ports, they always
seem to spin up perfectly.

Is this a power problem?  Is anybode else seeing this?  What are my
options, besides not using the disks? ;-)


TIA & cheers,

Jukka
