Ric, can you press harddisk vendors hard enough such that those model and revision numbers squeeze out of them?

Thanks.


I will certainly push to get drive vendors to work with us on this. It is in everyone's interest to have the drives avoid stressing features that are not stable ;-)

Even better, we can usually try to work the bugs out with vendors before the drives become public which should help minimize the issues.

Just thinking out loud, but it would be really helpful to get drive vendor's a basic set of tests for Linux systems - error handling, performance, SMART features, etc - that would run natively on linux. We would need to get something really easy to deploy, like a live CD image with the test suite that could be booted on a pc, to get into an environment that is used to booting DOS based floppies...
