Preclear issue before preclear runs

Featured Replies

I tried running preclear on all three of my drives. 2x toshiba dt01aca300s and 1x seagate (common 3tb model) One of the Toshiba drives is running at 150-180MB/s (the seagate is about the same) but the second toshiba drives spits this out before it even starts:

smartctl may not be able to run on /dev/sdb with the -d ata option.

however this should not affect the clearing of a disk.

I ran the exact same options on this drive as I did on the other drives.

 

After selecting yes I get this:

Are you absolutely sure you want to clear this drive?

(Answer Yes to continue. Capital 'Y', lower case 'es'):

 

After saying yes to this, I wait a few more minutes then it begins scanning like the other drives. Instead of scanning at ~160/170MBps, its scanning at 4MBps.

 

 

Is this drive dead / DOA? ...Looks like it will take roughly 10 days for the first test to complete.. I guess that means it is a bad drive then?

 

 

BTW, I vote a different human verification method is used... I'm not familiar with these questions :P

...there is a chance that it is indeed DOA.

 

However, I*d check some more things first as the readson for your problems could as

well be a bad s-ata cable, bad power connector/adapter or a bad s-ata port/controller.

 

Some hints for testing:

- as you have two of the same model type toshiba disks...did you try and swap these

- check the FW version of the "good" toshiba...is this the same as in the "bad" one?

- double check cables and power connectors...replace with the ones from a "good" drive

- test the "good" drive with the cables, power connectors and in S-ATA slot of the bad disk...are/stay these still good?

Thanks for the tip there. I did this around 3am after work so I was definitely missing some things.

 

I tried swapping sata cables and now I get this on the same drive:

Do you wish to continue?

(Answer Yes to continue. Capital 'Y', lower case 'es'):

I am no expert with these reports.

What worries me is this:

 

197 Current_Pending_Sector  0x0022  100  100  000    Old_age  Always      -      8

 

For a new drive I'd expect this to be zero.

Does it run faster during preclear now?

  • Author

Nope, it actually began reading slower than 3MBps, ~450KBps as I kept switching and re-testing.

This actually doesn't look good.

Did you swap this "bad" one with the "good" toshiba you have...this includes S-ATA cable *and* power.

 

AFAIR Toshiba does not offer a Disk-Diagnostics Tools for other that Fujitsu rebranded disks.

However, I *think* these disks are still HGST ones (check the label, my 3TB toshibas do).

So you could use this http://www.hgst.com/support/downloads#DFT (windoze), test and then RMA the drive along with the report

 

Edit: Also, maybe post your results/problem here...I guess, this is where the experts will provide help/feedback first; http://lime-technology.com/forum/index.php?topic=4068.0
