[Re: preclear_disk.sh - a new utility to burn-in and pre-clear disks for quick add]

Yeah, all of my drives are either CC1H or CC1J.  I bought the server direct from Lime-Tech and it came with 4 of the CC1H and they work fine (except one of developed an unrecoverable sector or three and I had to RMA it with Seagate).  I also always seem to get CC1Hs from NewEgg, I did get two of the CC1J from Amazon, and apparently there is no firmware to upgrade them to CC1H, you just have to buy em that way for now.  I did run the latest firmware upgrade util on all the drives and it always said the latest was installed... They've been running for quite a while now with no problems, that's why I appreciate your script.

 

Thanks again!

Joe,

 

Thanks for the quick reply.  I'm sure I did format them before, I haven't added drives in a while so it seemed new to me.  But you point out the very reasons this script is so awesome, exercising the drives (especially to see if there are any oddities, especially important with these 1.5TB drives( and letting me keep the array live while it does it's thing.  I didn't realize you could run this on multiple drives at once until this time when I did 2 simultaneously in different terminal sessions, way cool.  Thanks for taking the time to make such a great tool for all of us!

I've used the preclear script on several of my drives to great results.  I just used it on two new drives a Seagate 1.5TB and a WD 1.5TB (wanted to see if the WD works well).  Anyway both ran through the single cycle including pre and post reads.  Everything finished on both fine as usual (though the WD took over 18 hours while the Seagate took the usual 12:12).  When I shutdown, moved them to their new drive locations and started up, both showed as unformatted and I had to format them for them to be usuable.  In the past I seem to recall they simply become active...  Anything I did wrong or is it that I brought both drives up at the same time, I think in the past I did one at a time...
