Hi Greg, Do you know of any pointers to increasing the performance (in general) of FreeBSD's IDE drivers by tweaking the kernel settings? A related story: I have a 1Gb drive which came to me marked "faulty", but I ended up putting it into a FreeBSD machine and it has worked flawlessly for the last 18 months. I recently put it into a Win95 machine and it's been gradually corrupted to the point where the file system is almost unusable. If I only used Windows I'd probably also be considering it faulty. I'm guessing it's because FreeBSD is more conservative (by default) with IDE settings/features so it's being more gentle on the drive. Windows is trying to automagically milk every last bit of performance out of it so that's why it is failing. Time to put it back into a FreeBSD box methinks. :-) Cheers. -- Rowan Crowe http://www.rowan.sensation.net.au/ Sensation Internet Services http://www.sensation.net.au/ Melbourne, Australia Phone: +61-3-9388-9260 To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-isp" in the body of the message
