Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii Date: Tue, 28 Jan 1997 15:02:42 -0500 From: Robert Withrow Sender: owner-hackers@freebsd.org X-Loop: FreeBSD.org Precedence: bulk I didn't get anything on the newsgroup: I have a P6-200/VS440FX/2.1.5 system in which I have tried two different ATAPI CDROM drives (a Creative 8x and a toshiba 4x). I get corrupt data when I read large files (like FreeBSD distribution tarballs.) If I repeatedly mount/md5/dismount I get different MD5 checksums for large files each time. If I boot W95 and copy the file, then reboot FreeBSD, the MD5 checksums are OK. Since I have two IDE hard drives on the other channel of this system (working fine on FreeBSD) and the CDROM works on W95 I am reluctant to think the hardware is broken. I thought only the probing of ATAPI CDROM drives was broken. Is reading them (once probed) also broken, or what? ----------------------------------------------------------------------------- Robert Withrow, Tel: +1 617 592 8935, Net: witr@rwwa.COM
