    Hey guys!
    I bought a SANDISK USB 256Mb pen drive. But I'm confused if it is or not corrupting my files.
    I did some tests:

    1) I transfer a 200Mb .ISO file to the pen drive and restart the computer. Then I check for the CRC32 / MD5 code and those codes are different form the original ISO file.

    2) I pack some files into a ZIP / compressed file (about 200Mb)and send it to the pen drive. Then I restart the PC and transfer the file form the pen drive to my HD. I test the zip file (using winzip 9.0) and it says all files is ok.

    3) Another day I tranfered a 1Mb corel draw file to to the pen drive and it corrupted the file.

    Please, help me to understand it!

    What OS are you using? Have you formatted/partitioned the drive with standard tools? Have you turned on write caching on the drive? Do you have to restart the computer to make it corrupt things?
