Thread: Vast PVR & HDD

I think you'll find most external HDD's which have an external power supply require to be turned off separately to the device they are connected to... including computers.

Every external USB drive I have (different brands, capacities and enclosures) are not switched off by the device they are connected to.

I set one up for a mate and it has the same problem and is the reason why I would never entertain buying this particular box.

Cannot use a Usb stick only use an external hard drive according to the manufacturer and the testing I done myself .

So you shall use more electricity and wear out hard drives.

An inferior box in my opinion.

You would think it would go into power save once the receiver was turned off with it realising no USB connection and the drive spinning down. Try another drive. Have you used this same drive with the MS9100?

this problem came up during the trial and I thought it worked with the drives they provided.
Heres the report I sent

Is it possible to send the HDD to sleep mode after a certian amount of
inactivity then have it start when a scheduled recording begins.

Thanks for your suggestions.

Most drives actually spin down on their own if no data comms have occurred for
a period. On the field trial build, we are forcing the HDD to remain active, so
that it is always immediately ready to begin reading/writing.

Some HDDs can take up to 30 seconds to become fully active again, which would
negatively affect the user experience for any interactions we cannot predict
beforehand (e.g. playback, instant record, and pausing live TV).

For future releases, we are looking at some ways of putting the HDD to sleep.
The most basic implementation would be to spin the HDD down whenever the STB is
put into standby mode. It can spin itself up again a few moments before any
scheduled recording is about to start.

It's a simple task, we just have to ensure that the implementation cannot ever
affect the normal user experience negatively.

Thats good news Im sure people dont want the HDD spinning away for a couple of
days waiting for a scheduled recording to begin, great for the electricty bill
also

New release will be available this week and will hopefully address this problem
and the HDD will go into sleep mode when the 4121 is in standby and not
recording.

& so did the new release fix the problem?

I'm hoping so as I bought a Seagate 1TB that powers down the drive to idle with a quick start up response when needed. Still waiting for OTA PVR upgrade of course.
Living on a stand alone power system, I can't justify having a hard drive running flat out while waiting for a recording & if I have to switch it on & off manually to time for the PVR function it negates the purpose of a PVR!

Tiny, no it hasen't even been done yet. I've just bought my box last week so they wrote that on the 30/05/2011, i mean how long is a piece of string

Or maybe my box was in the retailers store before that

What OTA upgrade are you talking about?

The OTA upgrade of standard UEC 4121 decoders to the PVR version that is coming sooooon, its been mentioned a few times in the VAST forum, you know the one, your in the thread.

Grrrr, I'm no longer looking forward to the upgrade then.
Other Sat box manufacturers have worked this out, WTF.

I'm currently recording VAST using the Auto Tune function & setting my Sony PVR to record at the right times. Not that I record that much of VAST anyway.

Can always use the hard drive for something else.

Thanks, h8fg4

What was your brand of Hard Drive ?

Did it just "spin down" like in power saving mode when the STB was in Stand by ? (& did the Hard drive light remain on ?)

I think this is what is supposed to be happening....

or did it completely shut down the Hard Drive...?

Cool, thanks for the info Thomo, that's the drive I bought.
Feeling a lot better & I'm looking forward to the upgrade again.

Further to thread 12 above uec says that they will be providing an update to allow the HDD to turn off when the stb is in standby, but didn't say when that's going to happen. If thread 7 above is any indication that could be a long time to wait.
