system-windows 7 64bit ultimate,Intel i3,8gb ram,1tb hd

Ive purchased a 64gb toshiba memory stick usb2.0 The speed the files are written to the memory stick varies from 3mb\sec to 25mb\ sec I use it to watch video in the usb slot on my lg bluray player Problem is some of the video files do not copy,they appear to have but they havent,this happens if the write speed is 25mb\sec at 3mb\sec works fine why is this? doesnt matter the file type or indeed the size

you could try this solution posted by 'ArcAiN6' on answers.microsoft.com plug your memory stick in, then:

"In Device Manager, right-click the USB drive in Disk drives folder, then select Properties, switch to Policies tab, and choose Optimize for performance. Click OK to keep it."

"NOTE: If you use this method, make SURE you use the sub removal tool that pops up in your system tray when you first plugged in the device (system tray is the little area near your clock on the task bar)"

Actually re-reading that, it might be easier/better(?) to do it via windows explorer by rightclicking on the usb memory stick | Properties | and then the Policies tab.

Thanks ive already done this few weeks ago to no effect I arent really bothered how fast the memory stick writes if it copies the video in its entirety but it doesnt,i get the message in vlc "broken avi index" Today ive copied 6 files same format same size at 3mb\sec the seventh one sped up to 25mb\sec and the result is an unplayable video,even though clicking on properties gives the correct size for the file its not copied across fully

Maybe the memory stick has got 'bad patches' or something - I'm just guessing now, sorry.

Well here's the specs and it's got a 5 year warranty so I suggest you get it replaced under warranty.

lotvic thanks the reviews on amazon are fairly accurate to the problems im having,the memory stick has been replaced 2x still same crap Ive heard about lot of fake memory sticks that say they have 64gb capacity but only have 8gb I used this utility it reported 62.5gb http://sosfakeflash.wordpress.com/2008/09/02/h2testw-14-gold-standard-in-detecting-usb-counterfeit-drives/ think ill forget it its too unreliable,i do have a 64gb unknown make one which performs excellent and an 8gb sandisk which also is faultless

thanks for your help
