If you update to 5.x or later, you can use background FSCK rather  than

having to

wait for the FSCK to complete the way it does under 4.x.

I wasn't aware 5.x could do this. My next question is how are my existing
apps going to be affected by upgrading to 5.x?

If you install the 4.x compatibility libraries, your old 4.x binaries should continue to work just fine. However, you will want to rebuild as much of your existing software under 5.x as possible.

Also, if you update to 5.x, you can run the smartmon tools, which will let


do a drive self-test using SMART, this will give much better information


what is going on with the drive, and also give an estimate of its remaining

Yes, this would help a lot!!!

Well, once you're running 5.x, install smartmon and run: "smartctl -t long /dev/ad0", or whatever the right device is.

How old are the drives, if you know?

They're less than 2 years old, and still under warranty. This is the second
drive to fail and it's driving me nuts.

They're Maxtor DiamondMax Plus 9 6Y250P0 250 GB PATA drives... Never had a
problem with that particular drive until this batch.

Can anyone suggest some good 250GB PATA drives for me to use? I  might as
well swap them all out since I'm starting over. The 6000 series  Escalade
card I'm using doesn't support anything more than 250 GB.

I've had somewhat better luck with the so-called "special edition" variants of the drives, such as the WD1200JB, which have more cache RAM and a longer warranty period than the generic versions....

According to Western Digital, ONLY their 'SD' or (RAID-Edition) drives should be attempted in an array; WDC utilizes proprietary error correction mechanisms which mangle the error-handling done by an array controller. In short, while the drive is doing it's internal error-correction, the raid controller sees it as a drive failure and a whole new mess develops.

We've run into this several times now, both with our own in-house systems, and with those we've procured for others... trust me on this, if going with Western Digital drives... DO NOT use anything other than their 'SD' or RAID-Edition drives. Maxtor drives have no such issue AFAIK, nor Seagate... but only speaking from experience here not factual data. - WDC has a good explanation int he knowledge base on their website/support section.
