Has anyone out there noticed a problem when using an internal 250mb zip drive writing large files to a 100mb zip disk. I have one machine that locks up for a 8-15 minutes to write large files examples include (power point presentation 50mb file). It has never locked up while writing a large file to a 250mb disk. The machine in question is a 8200 Dimension, it has the XP operating system. IDE devices are One CDRom, One CD-R/RW, One Hard Drive and One Iomega 250mb zip Drive. Factory Strapping for Master/Slave/Cable select. Previous Corrective Action: I have already had the drive replaced, loaded all service packs, for XP and office, and loaded the iomega ware software. Dell can't give me an answer. http://support.dell.com/us/en/kb/document.asp?DN=1014241 Any previous experiences, known solutions or causes to this problem would be appreciated, Lee Lee Duynslager Michigan State University Center for Integrated Plant Systems Information Tech.
