Re: [qmailtoaster] Re: concerning server for qmailtoaster
Rajesh, He is referring to an addition to cars that increase the horsepower with nitrous oxide injected into the intake. This is a very popular way to increase performance in street cars and drag race cars. See http://en.wikipedia.org/wiki/Nitrous So he's saying that Jake's tweaks act like adding "nitrous".

[qmailtoaster] Re: concerning server for qmailtoaster
These appear to indicate a problem with the drive: Errors logged 7934 errors detected Self-test execution status The previous self-test completed having the read element of the test failed. I don't know that this conclusively proves that this is the cause of your past problem, but together with the fact that the problem went away with a new drive seems to be a pretty good indication of a problematic drive. Check the serial number online at the WD site. If it's still under warranty (usually 3yr), they'll send you a new one if you send the faulty one to them (get an RMA for this). WD is great about that. You simply need to pay for shipping the old drive to them. I've done this on numerous occasions, and with other manufacturers as well. -- -Eric 'shubes' Rajesh M wrote: hi eric here is the SMART DATA as you wished to view.

Re: [qmailtoaster] Re: concerning server for qmailtoaster
I have got to get registered to get these.. Ive putting it off to long.. I ve been working with qmt since 2004 and luv it.. I feel like it is an integral part of my core systems and if it has an issue then the whole core has an issue. I want to be more part of development but I am still putting together gear to help with this.
