Hey guys,

Just bought a new sony bravia w800b. I connected my portable HDD to watch a movie, and as i was loading the files, the TV displayed video files which i deleted months ago. (FYI video files = TV shows, nothing dirty :P). I checked on my computer to see if the files are present somewhere else, however found nothing, I only have 4 folders in the whole drive, it is pretty much empty. I have no clue how the TV is reading my old deleted tv Shows, and whats even more weird is that, the files ACTUALLY WORK! I watched a few full episodes of big bang theory, listed to 5 of my 10000s playlists, all of which should not even be in existence right now! All those media files equate to 30-50gb worth of space, however ive only used up 3GB. Very confused, does anyone have any insight to what might be happening? Does the TV somehow read media file dropping ?? Is there a cache of some sort in the HDD itself containing old deleted files?

Cheers.

Note: HDD brand is Asus, 250gb over 8 years old.

i have this issue too.

no idea where the cache is, but i stream via the wifi and homegroup to the tv.

however the tv will show files i deleted 6 months ago from the computer. very strange.

Exactly it. No clue where these files are. Do HDDs feature some sort of recovery drive ? TV might be reading the clips from that.

From my understanding, when a pc deletes a file it only erases the info to locate the file on the HDD. It doesn't actually erase the physical information on the drive itself. It's not until you either write over the data with other information or do a secure erase with specialised software that the "deleted" content is gone. This is how software recovery works. It scans the physical sectors and reads the information off the HDD directly. I can only assume that the TV is reading the data directly from the disk and because you have not written over it yet, it can be read.

Wow actually never thought of it that way, makes sense though.

If you change the pc settings to view hidden files and folders in control panel you might be able to see the deleted content. I know when I delete content on my external drive it goes into a "hidden" '.trash' folder.

I think Sony uses a linux based OS for their smart stuff, so it can pick up the 'deleted' files; Windows would read some sort of file location table. Since the location info is gone (as stated above), it doesn't know those files exist.

My AVG Free has a shredding function for the recycle bin, which I assume overwrites the sectors.

Hmm thats pretty interesting, explains why a full format takes a couple hours while a quick format takes 1 minute. Must be that file location table thing just being erased rather than actually cleaning the HDD.

and LOL @ the family TV comment, definitely a worry, dad comes home chucks in the HDD and bam! "daddy why are those men on that lady"

i used to have a program which totally wiped a disk, basically it would wipe all info, then write at binary level all 0 then all 1 then clear again so all data is over written.

Once data is written to a hard drive it cannot be removed, only overwritten. Thus even the most thorough of disk formatting serves only to write over each bit with gibberish binary.

File recovery services from computer stores / techs are pretty much based on the assumption you've only deleted the file from windows.

    • I came here to note that is a zener diode too base on the info there. Based on that, I'd also be suspicious that replacing it, and it's likely to do the same. A lot of use cases will see it used as either voltage protection, or to create a cheap but relatively stable fixed voltage supply. That would mean it has seen more voltage than it should, and has gone into voltage melt down. If there is something else in the circuit dumping out higher than it should voltages, that needs to be found too. It's quite likely they're trying to use the Zener to limit the voltage that is hitting through to the transistor beside it, so what ever goes to the zener is likely a signal, and they're using the transistor in that circuit to amplify it. Especially as it seems they've also got a capacitor across the zener. Looks like there is meant to be something "noisy" to that zener, and what ever it was, had a melt down. Looking at that picture, it also looks like there's some solder joints that really need redoing, and it might be worth having the whole board properly inspected.  Unfortunately, without being able to stick a multimeter on it, and start tracing it all out, I'm pretty much at a loss now to help. I don't even believe I have a climate control board from an R33 around here to pull apart and see if any of the circuit appears similar to give some ideas.
    • Nah - but you won't find anything on dismantling the seats in any such thing anyway.
    • Could be. Could also be that they sit around broken more. To be fair, you almost never see one driving around. I see more R chassis GTRs than the Renault ones.
    • Yeah. Nah. This is why I said My bold for my double emphasis. We're not talking about cars tuned to the edge of det here. We're talking about normal cars. Flame propagation speed and the amount of energy required to ignite the fuel are not significant factors when running at 1500-4000 rpm, and medium to light loads, like nearly every car on the road (except twin cab utes which are driven at 6k and 100% load all the time). There is no shortage of ignition energy available in any petrol engine. If there was, we'd all be in deep shit. The calorific value, on a volume basis, is significantly different, between 98 and 91, and that turns up immediately in consumption numbers. You can see the signal easily if you control for the other variables well enough, and/or collect enough stats. As to not seeing any benefit - we had a couple of EF and EL Falcons in the company fleet back in the late 90s and early 2000s. The EEC IV ECU in those things was particularly good at adding in timing as soon as knock headroom improved, which typically came from putting in some 95 or 98. The responsiveness and power improved noticeably, and the fuel consumption dropped considerably, just from going to 95. Less delta from there to 98 - almost not noticeable, compared to the big differences seen between 91 and 95. Way back in the day, when supermarkets first started selling fuel from their own stations, I did thousands of km in FNQ in a small Toyota. I can't remember if it was a Starlet or an early Yaris. Anyway - the supermarket servos were bringing in cheap fuel from Indonesia, and the other servos were still using locally refined gear. The fuel consumption was typically at least 5%, often as much as 8% worse on the Indo shit, presumably because they had a lot more oxygenated component in the brew, and were probably barely meeting the octane spec. Around the same time or maybe a bit later (like 25 years ago), I could tell the difference between Shell 98 and BP 98, and typically preferred to only use Shell then because the Skyline ran so much better on it. Years later I found the realtionship between them had swapped, as a consequence of yet more refinery closures. So I've only used BP 98 since. Although, I must say that I could not fault the odd tank of United 98 that I've run. It's probably the same stuff. It is also very important to remember that these findings are often dependent on region. With most of the refineries in Oz now dead, there's less variability in local stuff, and he majority of our fuels are not even refined here any more anyway. It probably depends more on which SE Asian refinery is currently cheapest to operate.
    • You don't have an R34 service manual for the body do you? Have found plenty for the engine and drivetrain but nothing else
