When I try to use preclear it just sits as starting. I let it run for two days and still saying starting with an empty log.

So just have to wait another 40 or so hours to see reports from the first pass? [emoji41]

Anyone here tried the docker version to see if it fails there too?

I'm 10hrs into the Pre-Read with the Docker version on my drive so in about 18 hours I'll let you know 🙂

I am also running the docker now.  10TB will take a while

I've just gone back to the previous version, and it works fine. Ran a full preclear on a smaller drive (which failed MBR verification on the new one) overnight.

 

Just pull from the prevoius commit like so:

https://raw.githubusercontent.com/gfjardim/unRAID-plugins/2e4cd4b6568c64b58782388eff7fba550e91da03/plugins/preclear.disk.plg

 

I'm assuming this move to starting from sector 64 (rather than 1) has it misassigning during the MBR verification. Can't say for sure, but one thing I know is someone doesn't check their commits :)

also getting the "Preclear signature FAILED" on a WD My Book 8 TB via usb

How did you find those?  I spent way too much time looking for previous plg files yesterday but I'm not much of a Github user.

One can look through the entire commit history and find previous versions of files from here: https://github.com/gfjardim/unRAID-plugins/commits/master 

 

Cool, thanks!

Ok, guys, @HeyBurt is right, apparently the formatting part got right but the verification doesn't. I've just updated the plugin to try to solve this. I've added more debug verbosity to help me fix it in case this update doesn't address the issue.

 

For those that want to test it, there's a small trick to limit the preclear routine to the first 4Gib of the drive. In <server name> > Tools > Preclear, hit Help in the menu bar, than click Start preclear.  In the dialog, at the bottom, you have to select Enable Testing (just for debugging). This will limit all read/write routines to the first 4Gib, and as the name say, speed up the debugging process. If it's successful, I still recommend a normal/full pass, even if the disk has been zeroed before.

 

In case of issues with the new version, please send me the logs.

This test worked for me as well.  My x2 12TBs from WD easystores have failed once or twice already with the signature error.

 

Currently they are running again starting from the ZERO point (skip pre-read).

my 3TB just finished and succeeded!

Although when i added it to my array its now clearing it again?

My 10TB cleared successfully using the Docker plugin.

I also just ran the Enable Testing (just for debugging) option with the latest Plugin (2019.11.27) and it finished fine.

 

Thanks @gfjardim !

so since I’m just starting out my unraid and i’m new around here, I added my drives to the array to start messing with things and getting used to it, how would i go about running the preclear tests on the drives now that they’ve been added? i don’t care about wiping out the data yet

Remove them from the array configuration using the new config tool. You can't preclear drives that are part of the array.

thanks! figured it out

Hello,

 

I have ran preclear on two separate disks and both fail writing zeroes to the drive saying it failed mbr write.  These are being run on 10g drives and happens about 24 hours in.   Is there something I’m doing wrong?

 

TIA

Have you updated the plugin? There is an update released day or two ago for that exact issue.

 

If you have updated and the problem still is present, send logs so the author can take a look.
