I have recently purchased a kingston 512MB USB pen drive, to which I can copy data. The problem arises when I try to install the copied software back to the HDD from by pen drive. I get crc and all kinds of data error on installing. I got it replaced and I am still having the same problem. So, I want to know whether it is possible to carry large data files including software without corrupting it. Has anyone here been able to copy and install software back from the pen drive. Also another intriguing thing is that the media files work perfectly fine no matter what its file size may be. I am absolutely flummoxed! Please help. Also the small programs or software work perfectly fine when I install them from the pen drive. It is only a problem with the large software. The pen drive is both USB 2.0 and 1.1 compatible. I generally use archiving tool winrar to compress the software. I have also tried coping the installer and installing from it but made no difference. I aslo want to know are these pen drives only meant for document, media, presentation files and not for software. Should sound stupid !!! Also I forgot to mention here that I have tried it in different comps and everywhere it gives the same errors. I tried connecting it to comps with the extension connector that comes with it and also directly to the USB ports. I have Windows XP SP2 installed on my system. Please Help.... And Thanks in advance.

Just to let you know I have successfully copied installation files up to about 150MB in size on my USB drive with no problems whatsoever. Have you tested the compressed file before copying it to the disk? You're ejecting the hardware properly before removing it from your PC too, right? Otherwise, I'm confuddled :)

Thanks for clearing my doubt. So I guess this could be an issue with the drive itself. And yes I have tested the compressed file and uncompressed setup file as well.

You didn't answer about properly removing the drive in Windows before unpluging it.
