GVP HD8+ problems

[Etherweet]

(remember this thing has a small fan that can sound like a disk drive - allthough quantums have a unique noise of their own)

(( fan running could be an indication 12 volts is there at least))

if you do open the case you can disconnect the hard drive power lead and measure the voltage safely there.  the 2 inner conductors are both ground and it wont matter which one of those you use.

you should see 5 volts and 12 volts.  should be in 5 to 10% tolerance to get a hard drive to unpark and do internal diagnostics.

if the supply voltages are wrong the fan could possibly still run.. too fast or too slow...

im almost willing to bet the green power led is on the 5 volt supply and the fan is on the 12 volt supply. so if you have the green power light lit and the fan spinning, you have a good idea whether you want to go inside or not.

- just plugging my .02 in -

at this point i would say disconnect the scsi cable from the hard drive.

then boot up with the hd8 connected.

this will prove the disk drive is not coming up ready and is holding tee scsi bus up.

the hd8 probably does a scan from device 0 to 6, giving each unit time to come up.

if it detects the hard drive but the hard drive is broken then it waits for a ready repsonse that may never ever come.

booting with the drive physically disconnected shouold prove this...
