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.

      Pops when backing off throttle, rough-ish sound through rev range.

      Hence why I suggested some tests.

      Yes to both! Yes to standard ECU and tune, but exhaust is aftermarket. Unsure on brand. Actually have it sitting in at my desk haha! I have to set it up on my laptop but this is a great next step, will do. So I generally try to shift before 4.5K RPM most times. I largely don't do a lot of high-rev driving, but I will take it up to red 1-2x a week max, as I know the occasional "Italian tune-up" is good for these cars.  Oh wow, is this way better than what I'm getting. Does this mean there's a good chance I have an issue?   Thanks for all the info so far guys.

      Old Son, did you re-use the Holden ABS in the new shell or try a different module?

      Another little story of weird shit happening

      Yeah, nah. I had the actuator rod off it today. The arm will not move at all. Neither out, nor in. Yeah, you'd think so, but I've been thinking about that. Even when the actuator rod fell all the way off at the beginning of this saga, it would build more boost and faster in lower gears than it would in higher gears, and you'd think that that was the opposite of what should happen. But I strongly suspect that there is a thing with the gearing getting the revs to rise faster, that there must be some transient effect with the gas flow rate rising quickly, that you don't get with the more steady state case of the higher gears. Keep in mind - the gate is not shut in either of my weirdnesses. So things are not "normal". We normally think about a turbo spooling up (below the wastegate target) with the gate shut. I have all sorts of mental models running now where the gate is a little bit open, and having it stuck open allowing gas out while it should be going through the turbine has all sorts of weird effects (in these mental models). I'm thinking in the higher gears, the ex mani pressure builds to the point where enough gases spill out the wastegate to just prevent the pressure rising much more at all, or just creeping up, all the whole the revs are increasing and getting closer to the point where a gear shift becomes necessary.

      Is it possibly wastegate actuator itself is sticking, or even the rod to flapper? Otherwise I reckon things are getting a bit rusty/worn   Also odd it won't boost in 3rd to 5th, but will in 1st, I'd expect the other way around with it slightly open as there's more time on your way to redline for it to spin up
