Hi, I'm getting an 'Invalid disk' message during the boot process of a P166 w/ a 2GB hard drive. When I boot to a floppy, I can type C: and the prompt appears, but when I try to access the drive with a dir command, it returns a CDR001 message which I've never seen before. The drive is recognized at the BIOS level. Does anyone know what that message means? The operating system was the latest W95 release. Thank you. chuck finnigan [log in to unmask] Do you want to signoff PCBUILD or just change to Digest mode - visit our web site: http://nospin.com/pc/pcbuild.html
