In an effort to keep the Preclear script thread more about questions about the script itself, I've started another thread here to discuss the results. The preclear thread is peppered with result questions and questions about the script and is now 15 pages long! So I'm thinking that a seperate thread was warranted. So I'll start it off... If it stays at 5, in my opinion, no problem. If it increases over time, then you might want to use the RMA process. Odds are good it will stabilize. I have one 250Gig drive that has had 100 relocated sectors since the first time I ran smartctl on it. That number has never changed on that disk. I'd say, download the new version of preclear_disk.sh and run another set of test cycles and see if it shows an increase in re-allocated sectors. (the new version stress-tests the drive more. The old one had a bug that prevented the random cylinders from being read in addition to the linear read that was properly occurring) If the number stays at 5, fine, if not another test cycle might be in order. At that point you have all the evidence you need if an RMA is warranted. You might want to start a thread with your preclear experience. It will allow the questions about the output to all be in one spot. Joe L. Ok.. I ran one more full cycle with the new verions of the script and I got no reallocated sector changes. Should I run once more or do you think I'm good now and can put the disk into service? So... first 3 cycles. - 5 reallocated sectors 4th cycle - no more reallocated sectors. Jim

I haven't tried any of these.. but they seem pretty new. Good competition for the WD green drives? @ $109.. This seems like a good deal! Too bad I just bought a 1TB.. Have to wait till next credit card cycle! They are normally $115 but if you get hte newsletter and the code it's $109.99 FYI...

After running 3 interations on my new 1TB green disk I had < 5 Reallocated_Sector_Ct 0x0033 200 200 140 Pre-fail Always - 0 --- > 5 Reallocated_Sector_Ct 0x0033 199 199 140 Pre-fail Always - 5 64c64 < 196 Reallocated_Event_Count 0x0032 200 200 000 Old_age Always - 0 --- > 196 Reallocated_Event_Count 0x0032 199 199 000 Old_age Always - 1 Are 5 reallocated sectors anything to worry about.. I was hoping for 0! This is still running on the old version of the script.. Maybe I should try the new version.. (I started my test the morning before Joe posted the new version!) I did start a cycle again on a different controller (one cycle this time - and still the old script) Another thought... Should we start a new thread for preclear disk result questions and keep this thread for questions/comments about the functionality of preclear? Jim

If you do use the mail programs listed from the posts above (from unraid_notify and it's mail offshoot) you will have to use the -m [email protected] command line parameter It will not default to the e-mail address in the unraid_notify.config file. Maybe we can change the mail script to handle "root" as a recipient someday.. I'm still hoping that brianbone will update the package into a seperate mail and unraid_notify package! Jim

My slightly more efficient PS (replacement - first died) should come in tomorrow. That will be another7-8 watts. (That's what I noticed when I swapped it out the first time before it died) Maybe I won't have to switch to a new MB yet. If I still get ~70 watts with the drives spun down with the new power supply, I probably should be happy with that! I'm at ~74W with the older PS.

I just took out my apg video card and put in the dirt cheap pci radeon and my power dropped almost 25 watts! I was hoping for about 10 watts! I was surprised to say the least!

Fine with me!

Does it? Maybe I'm thinking of Quest or Comcast. I'm going from a distant memory of an ISP that does not require SMTP Auth, as long as you're sending mail from within their network... Earthlink had come to mind for some reason. Man -- I'm getting old. Let me rephrase that.. Outside the network (which) is how I mostly operate... They require authentication. I don't know if I've ever tried smtp from with in the network. Since it's only for dialup backup and my mom's internet (she uses webmail) I've never tried from within... At least not with in the last 8 years or so!

My eathlink requires authentication?

Here is an updated version that more conforms to the berkley standard for mail. It will either take the old parameters or the standard ones. So Samples Usage: cat filename.txt | mail echo 'this is a test' | mail echo 'this is a test' | mail --subject 'ATTENTION' echo 'this is a test' | mail --subject 'ATTENTION' --rcpt [email protected] All still work or... cat filename.txt | mail echo 'this is a test' | mail echo 'this is a test' | mail -s 'ATTENTION' echo 'this is a test' | mail -s 'ATTENTION' [email protected] Will also work. This still requires unraid_notify to be installed The program is attached.. just remove the .txt Or the whole package is there too...

I'm looking to replace my laptop drive with a bigger one and I'm curious to see if they have regular SATA connectors for power. I want to run Joe's preclear script on it to run it through it's paces... but I don't know if I'll need any special adapters. I know the older PATA ones had a different conenctor and I had an adapter for that. But I haven't pulled the old one out of my laptop to check yet. My guess is they have regular connectors. That will also help me transfer the data to the new drive as well.. Jim

The thirst for adventure is outweighed by my thirst for more disk space! My cache drive is filling up because there is no room left on the array!

Whew! 56 hours of testing later, my replacement 1.5T disk passed 3 cycles! Thanks again for a great script!

So you are saying you are also known as google.com? Awww.. come on! Where's your thirst for adventure! Think of it as a challenge! I dare you to try! just kidding! Yeah.. Adding something to display_progress() function might be easy enough.. I'll tinker once I have some time.. but my guess is that I'll be done with the parity upgrade and forget about this until the next time! Oh.. and it is well commented.. good job!

Nice! Let me rephrase.. how hard would it be for you to modify this script to e-mail updates as the test is progressing :-) I've already got unraid notify working.. Maybe I will dig into that.. someday.. For now I'm having to connect back into the session every couple of hours.. :-) hmm.. redirect the output to tee and send the contents to bashmail.. hhmm... all with variables to disable it... Jim

Dumb question here.. I got got my replacement drive and it's on it's second pass. (18 hours for the first pass!) Since this is my new parity drive, do I really gain anything by running this script? (other than testing the drive) It's going to have to write all the parity anyway when I assign it, correct? oh.. And how hard would it be to modify this script to e-mail me updates as the test is progressing? Jim

Yeah... It's WD not Maxtor like I said in my original post.. My replacement drive should arrive today! Jim

Oh... and btw... Thanks for the excellent script!!! It probably saved me a lot of headaches!

Any tests you want me to try before I RMA the drive? It happily went through the pre-read and the zeroing out without reporting an error. I imagine it would have shown some problem when it did the smart diff, right?

Here is my hdparm info and smart test info. Interestingly.. After the power cycle my disk 2 was "missing" I power cycled again and it came back? Now I just have to see if disk 2 is on the same controller as my new disk.. /dev/sdd: ATA device, with non-removable media Model Number: WDC WD15EADS-00H7B0 Serial Number: WD-WCAUP0018631 Firmware Revision: 05.00K05 Transport: Serial, SATA 1.0a, SATA II Extensions, SATA Rev 2.5 Standards: Supported: 8 7 6 5 Likely used: 8 Configuration: Logical max current cylinders 16383 16383 heads 16 16 sectors/track 63 63 -- CHS current addressable sectors: 16514064 LBA user addressable sectors: 268435455 LBA48 user addressable sectors: 2930277168 device size with M = 1024*1024: 1430799 MBytes device size with M = 1000*1000: 1500301 MBytes (1500 GB) Capabilities: LBA, IORDY(can be disabled) Queue depth: 32 Standby timer values: spec'd by Standard, with device specific minimum R/W multiple sector transfer: Max = 16 Current = 16 Recommended acoustic management value: 128, current value: 254 DMA: mdma0 mdma1 mdma2 udma0 udma1 udma2 udma3 udma4 *udma5 udma6 Cycle time: min=120ns recommended=120ns PIO: pio0 pio1 pio2 pio3 pio4 Cycle time: no flow control=120ns IORDY flow control=120ns Commands/features: Enabled Supported: * SMART feature set Security Mode feature set * Power Management feature set * Write cache * Look-ahead * Host Protected Area feature set * WRITE_BUFFER command * READ_BUFFER command * NOP cmd * DOWNLOAD_MICROCODE Power-Up In Standby feature set * SET_FEATURES required to spinup after power up SET_MAX security extension Automatic Acoustic Management feature set * 48-bit Address feature set * Device Configuration Overlay feature set * Mandatory FLUSH_CACHE * FLUSH_CACHE_EXT * SMART error logging * SMART self-test * General Purpose Logging feature set * 64-bit World wide name * {READ,WRITE}_DMA_EXT_GPL commands * Segmented DOWNLOAD_MICROCODE * SATA-I signaling speed (1.5Gb/s) * SATA-II signaling speed (3.0Gb/s) * Native Command Queueing (NCQ) * Host-initiated interface power management * Phy event counters DMA Setup Auto-Activate optimization * Software settings preservation * SMART Command Transport (SCT) feature set * SCT Long Sector Access (AC1) * SCT LBA Segment Access (AC2) * SCT Error Recovery Control (AC3) * SCT Features Control (AC4) * SCT Data Tables (AC5) unknown 206[12] (vendor specific) unknown 206[13] (vendor specific) Security: Master password revision code = 65534 supported not enabled not locked not frozen not expired: security count supported: enhanced erase 412min for SECURITY ERASE UNIT. 412min for ENHANCED SECURITY ERASE UNIT.

Seems like that should be 0 for a new good drive.. Could a bad controller have any effect on that number?

After the reboot it seems to be happily be running I'm at 98% of the pre-read... Ok.. Change that... I guess it isn't happy... I'm getting more of those errors on the zeroing.. Here is a snippet of the log. The snippet starts at close to the end of the pre read and captures the start of the zeroing.. I'm in the middle of a power cycle (remotly so I may not get it back). I'll have to look to see if the very first pass of this test behaved well... I'll post the smart results when the computer reboots..

I am running this on my new 1.5TB Maxtor Green. It did one full pass that seemed to work. On the second pass, it didn't finish. I looked in /tmp for the smart logs, but it appears to have been deleted. where should I look to see what happened? I remember seeing something about not being able to do something with the MBR. My putty session got killed when I rebooted. I'm going to try again and see if it was just some sort of fluke. My syslog file is 500Meg!

Jim

I could have done that! I'm looking for something on the main forum page! Not something in a post I have to go look for!

Is there an wasy way to post a link to the wiki on the forum page? I have the forum bookmarked, and I'm constantly having to go back to the root lime-tech page to get at the wiki. It would be nice if there was an easy way to get it from the forum main page! :-) Jim "I know.. I should just bookmark the wiki in my browser!"

Thanks! I already wrote the hdparm parsing code before you sent this! Maybe I should look more at the unmenu code! I want to try to include a space free in the unraid notify script!
