Strange problem with external disk .

portaro · 02-27-2021, 03:20 PM

I found a Solution for the video lag but I dont see if the problem is caused by hardware of disk (transmission data or supply) or if is a problem with anyone block of partition with problem that is undetected by ntfsfix, smartontools or testdisk.

The solution is on -cache mode of mplayer vlc etc.

I found this by the terminal output of mplayer or gnome-mplayer launched in terminal and with the target file on disk.

So this is (a half) solution:

************************************************
**** Your system is too SLOW to play this! ****
************************************************

Possible reasons, problems, workarounds:
- Most common: broken/buggy _audio_ driver
- Try -ao sdl or use the OSS emulation of ALSA.
- Experiment with different values for -autosync, 30 is a good start.
- Slow video output
- Try a different -vo driver (-vo help for a list) or try -framedrop!
- Slow CPU
- Don't try to play a big DVD/DivX on a slow CPU! Try some of the lavdopts,
e.g. -vfm ffmpeg -lavdopts lowres=1:fast:skiploopfilter=all.
- Broken file
- Try various combinations of -nobps -ni -forceidx -mc 0.
- Slow media (NFS/SMB mounts, DVD, VCD etc)
- Try -cache 8192.
- Are you using -cache to play a non-interleaved AVI file?
- Try -nocache.
Read DOCS/HTML/en/video.html for tuning/speedup tips.
If none of this helps you, read DOCS/HTML/en/bugreports.html.

A: 61.2 V: 61.2 A-V: 0.001 ct: 0.000 0/ 0 12% 5% 81.0% 977 0
[4]+ Parado

I take speciall interest in this part of the advice:

- Slow media (NFS/SMB mounts, DVD, VCD etc)

So I apply the cache 8192 value to gnome-mplayer then open the file and voilá the video runs well now.

But I dont know if the problem is with partition or with hardware.

Is only a half solution, maybe works for others with a similar problem.

Its a work around. Do you know if any updates were made recently?

As a side note.. Windows cares about the partition ID type but linux does not. The partition type ID is just some bytes in the partition table and has nothing to do with the actual filesystem.

If you have enough available space I would recommend temporarily removing (or doing a backup) of all the files on that drive. You then could use gparted or similar to set it as ext4 and reformat it, and restore the data. This likely would also handle the (possible) bad block issue.

Your smartctl commands have to be run on the device, not the partition, so if you change that to "sudo smartctl -a /dev/sdb" it would work properly.

If I run your suggested command it give me this output :

I cant see if there are a problem or not with this return of command, but I think that is all normal if anyone understand the outputs and see any problem please give me the posible solution.

No my system is based on Lubuntu 14, I test today boot from other distro, bunsenlabs open vlc and run the videos and is exactly the same problem occurs.

Thanks for your answer.

I have other question now -

If I download some windows from web xp or else create a vm machine in virtualbox and conect the device disk to the virtual machine with windows I can solve this ?

What is the program for windows that do this ?

portaro · 03-01-2021, 06:22 AM

I try to find a way to analyse partition via Windows virtualized, but now I have other problem in virtualbox the windows cant find any USB.

https://i.postimg.cc/DmVSxYnT/sh3.png

I already configure virtualbox with guest additons and expansion pack but nothing works, as you can see for virtualbox the USB are active but then in windows not.

I test with other devices and the disk and in any case Windows detect any USB device.

Anyone have any idea ?
