Date: Mon, 12 Jul 2004 11:13:04 +0200 I've got exactly the same problem on my JBS20 and we managed to find the cause for this behaviour, but not the part which is broken. Perhaps we manage to figure it out together: We measured the voltage applied to the HD when starting the JB and recognized that voltage is 5V if the HD isn't present while it is breaking down to below 1V when the HD is present. So obviously the powersupply for the HD is broken somewhere and we think it should be one of the fets switching power on and off. To see wether the unit would work if the voltage is present, we connected the power- pins of the ATA- Connector directly to 5V from an external powersupply. The unit works fine this way but it's not a proper workaround because the HD will stay in standby even when the whole unit is switched of. So in my eyes the first thing you might do is measure voltage on the ATA- Power pins, when you switch on your unit to see if our problem is really the same.
