Simple answer - No. But ... personally I keep my preclear reports so I can use them as a historical comparison so that when I run SMART reports on a disk I can go back and compare the results to when the disk was new. ty - i didn't know if UR needs it, for my uses, i did keep the .txt exports, the files in the folder, and all the emails. another question ... i have an older 500GB drive that isn't Advanced format. I have the setting in UR set to always do AF... how do i go about and pre-clear this drive? i thought I saw something somewhere about -a but can't for the life of me find it. OR should i just change the setting in UR and pre-clear? ./preclear_disk.sh -M -a 4 /dev/sda ? edit: found it in tutorial

does unraid need the files in the preclear_reports folder? The reason i'm asking is because the unraid install where i ran the pre-clears probably wont be the final production version. do i need to copy these over or *if* i decide to start fresh, can i just let all of these go? thanks! every little bit gets me closer to a finished product (and happier wife)

ah makes sense. i saw the esxi formatted drive have like 1/2 dozen. ty learned something today.

blech! == Disk /dev/sda is NOT precleared also i'm new to linux - is it "normal" to have the drives listed 2x in the main of Unmenu? i see /dev/sdb and then right below it /dev/sdb1 on the devices tab of unraid, the drop downs only show the actual number of disks.... so i should run another pre-clear then right?

gaaaaaaaaaaaaaaaa i was toying with esxi and it auto formatted one of the drives (i'm guessing sda)... will unraid think it's not pre-cleared, meaning i'll have to run another cycle on it?

funny thing the Post Read stage is running now and i've got 36c, 35c, and 34c all between 74MB and 78MB read speed.... looks like sticking them together, but in front of the fan has helped keep it below 40.. havent' broken that since this cycle started yesterday.

sda is now at 40c on the zeroing disk process, 25% it IS a bit warm - right now, the room is 80F or 26.6C. Is there a way for me to get case temp from unraid or this linux distro? Cpu is at: +56.0 C, +55.0 C, +54.0 C, +52.0 C. perhaps first I can try throw two fans on the side? Or maybe just get a 5in3 and put 1 or two HDs in there?

i've been thinking of a 5in3 for when I "release" the 1TB drives. After your first reply, i moved them so that they are in front- and on the pre-read cycles, i'm getting 39, 38, and 36 (top to bottom). Going to go dig for a decent 5in3. my machine sits in Living Room so need something not so funky on the look.

it's the Cooler master Storm scout: http://www.newegg.com/Product/Product.aspx?Item=N82E16811119196 I know it's not ideal, but didn't think drives would get this HOT. Pic below is from NE's stock photo. Sorry it's a bad scribble using win7 snipping tool. I can't get good photo of the actual unit w.o. moving it a good amount. wit the HD light solid, prolly shouldn't. Thanks for lookin @ it.

Okay so stackin' em didn't help much. more airflow, but temps are still same (perhaps a bit higher when it goes over to the write stage). SOO... the drive that is getting the highest (over 40C).. should I make that my parity drive, or keep it as a data drive? I saw a posting on here, about two types of drives - ones that have failed already, and ones that will fail. And high temps lead to failure... so is it better for a parity drive to fail or a data drive? right now it's on stock case fan. I can add two more to the side as exhaust and perhaps swap out the front one with a noctua or something. OH BTW, the reallocated sectors are at 0 so far. thanks for everyone's help still learning the ropes around here.

thanks - going to fire off another 2 rounds. the 40c has me concerned also. it was the 1 drive that's at the top of the drive rack. and coincidentally is "missed" by the intake fan on the bottom of the case (Cooler master storm scout). I have the drives spaced out so that there's a gap between them. before i fire off the next round, i'm going to put them closer together so they all get hit with the intake air. bad thing is i think I'm going to need to get a sata backplane or something when i decide to add more drives. I have 3x 1TB drives that would be in here by about december or so. Scout can hold 6x 3.5" but it would be too tight and would probably melt if i ran a pre-clear. Oh - I was also hoping that the temp wouldn't be too bad during regular non-stress use. thanks BRiT and Superorb. I planned on finishing up the ESXi + UnRaid build this weekend. I guess it's just pre-clears. :-)

So here are my results - any input would be greatly appreciated. there are three drives - sda, sdb, and sdc. WD20EARS, 2.0TB drives. Command I used was from config tutorial: ./preclear_disk.sh -A -M 4 /dev/sda (thru sdc). sdc Initial: ID# ATTRIBUTE_NAME FLAG VALUE WORST THRESH TYPE UPDATED WHEN_FAILED RAW_VALUE 1 Raw_Read_Error_Rate 0x002f 100 253 051 Pre-fail Always -

are people really running several cycles my 3x 2TB drives took a little over 30hrs to complete (running simultaneously). not sure that I want to run/start another cycle if not neccesary..
