Hmm, both probably :) Anyhow, I would avoid old Quantum/Maxtor/WDC drives as many of their models are know to have bugs in the DMA support. For brand new drives there are still some Maxtor/WDC models that are flaky.. The only drives I can recommed are IBM's, but beware the new DTLA series are so fast that some old controllers can have problems with them. And as always I'm interested in reports/patches to the driver to make as many drives/controllers work proberly. PS: I have just committed a huge update to the ATA code on stable, please try that out as it might fix some of the problems (and hopefully not introduce new ones)... -Søren To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
