Running win 7ultimate x64 installed from MS disc, slic bios activated. Problem I have is every time I put a zip drive in with files on it I get a message saying there is a problem with the drive and wanting to know if I want to attempt to fix it or attempt to use it as is. Does anyone else have this issue? I have several zip drives and it always asks. Yes my pute is USB 2.0. I can read and write files to the drives fine after selecting use as is. BTW some are formated FAT32 and others NTFS. I am also using a zip drive for readyboost.
