Re: Estar DM 800 se HDD problem

problem resolved. just insert to dm other HDD from laptop ,and they works. dreambox still cant find WD VelociRaptor HDD . i try format it ntfs ,ext2 ,ext3 . but result is same ,

So:
- hd VelociRaptor is ok
- receiver's sata interface is ok
- it's not a file system problem (you tried them all)

... it can only be a power supply issue.
Try to provide external power supply !

VelociRaptor still not working,on DM. with any file system . on pc,all ok.
hdd from pc working ok,on dm with NTFS . ext2 -3 not tested,on this hdd.
so i think, for VelociRaptor need more power.

Re: Estar DM 800 se HDD problem

does this VelociRaptor use the esata and no external power supply
that can be the reason

That's exactly what I meant !
If dm800 is not able to provide the requested current by hd, you should measure a voltage drop on connector, comparing to nominal voltage (5/12V)

I think that the problem is the sata.
The wd VelociRaptor is not recognized by the dreambox,
because is a new disk with SATA3.

Dreambox support sata, but maybe has some problem recognizing sata3 disk.
So, either your disk (on the drembox must work as simple sata) or the box have an issue with that.

maybe problem recognizing sata 3 disk. but i think , problem is with low power to. i found hdd power table :

WD Scorpio Blue

Average power requirements (W)
Read/Write - 1.6
Idle - 0.65
Standby and Sleep - 0.20


WD VelociRaptor

Average power requirements (W)
Random Read/Write - 5.1
Sequential Read/Write - 5.8
Idle - 4.2
Standby and Sleep - 1.1

Next step ,when i receive esata cable ,i will check VelociRaptor with esata + external power.

Re: Estar DM 800 se HDD problem

sata3 is backward compatible with sata2.
Of course, limitations of sata2 transfer rate will apply.

You are in the right way my friend
Take esata cable and test it.
If you still have problem try it with external power.

@gianni253
yes, sata3 is backward compatible to sata2 and sata1 but with limitations on speed.

HDD model HDD SATA 600GB 10000RPM 6GB/S/2.5" 32MB WD6000BLHX WDC

you CANNOT mount a 10.000 rpm hdd on dreambox(2.5 or 3.5)internal or esata

Can you elaborate further about reasons ? (interface, power requirements etc. etc. )
