USB stick memory corrupting files?

Taf · 25-02-2010, 15:44

I bought a DVD player recently that can play video files (xvid, mp4, etc) directly from USB memory sticks.

On one stick, all files in the same xvid codec, some played, others didn't.

The original files on HD all checked out perfectly with GSpot, but once copied to USB memory sticks, all stayed the same size, but GSpot could not identify any codecs on several. Copied back to HD they are still "corrupted".

I have tried several USB memory sticks, including high quality big name brands, and they all give the same results.

Copying other types of files (jpg, gif, doc, txt, etc) results in no errors.

Flash Drive Tester say all the sticks are AOK.

Any ideas?

Are they all the same make of USB Stick? Have you got an external HDD you could transfer the files to and plug that into your DVD player?

Several different brands, several different sizes. Don't have an external drive free for use at the moment.

Hmm...could be your copy of windows doing the corruption??

Have you tried burning them to DVD and trying them on another PC?

All were copied all AVi's to a DVD with no problem, also most have been burned to DVD format in the past few days using DVDflick, again with no problems.

I was trying them on USB stick to check out my new DVD player (Foehn & Hirsch HDMI DVD player 1080P DIVX/XVID/MP4 with USB playback) but the error seems to be copying them from HD to USB stick.

I will do as soon as the twins take a breather from their exam revision. (No way can I get on the missus' PC as she is playing with her Facebook pet again).

Sounds like a good time to broach the subject of a nice new Computer.

Just tried on the lad's PC... same errors on 5 different brand of sticks. Somone elsewhere just advised partitioning the sticks ?

Ahhh....no shortage then. Good stuff.

Back OT....Having a look around i seen someone on another forum mention it wont play from USB if there is a disk in the drive tray. Could that be the issue possibly?

USB sticks normally formatted in FAT - could you be running into a filesize issue?

Taf · 25-02-2010, 18:51

This model just needs you to click between disk and USB AFAIK...

Just tried formatting a stick to NTFS... will see if that helps... or not... maybe the DVD player won't be able to read NTFS formats...

This may be obvious, but have you run a full scan for viruses, malware etc recently?
I had a customer bring a machine to me with similar symptoms and it turned out to be a malware problem. There was also a virus his antivirus software (Norton) completely missed. I would suggest at the very least a quick scan using malware bytes anti malware free edition, and a virus scan. Incidentally what antivirus software are you currently using?

Taf · 25-02-2010, 19:41

Have scanned with Avira (resident), A2, Malwarebytes, SuperantiSpyware, and Spywareblaster is running... all up-to-date. This was one of my first thoughts... anything odd on a PC and it's either Windows or malware...

Taf · 26-02-2010, 19:04

I have formatted every stick I have at every possible setting, Fat32 and NTFS, then copied avi's to them at each setting... most suddenly get unrecognisable as avi files, but still remain the same size in bytes.

Did the same on the the 3 other PCs here (running Vista) and got the same result.

But, as before, all other file formats are unnaffected. I even tried coding as XVid, DivX, MP4... all have high rates of corruption.

That's it, I'm totally baffled now!!
