I'm curious to know what other data recovery specialists do in this scenario. We just purchased 3 new 1TB Seagate drives, don't have the model in front of me. I just got word that the first drive being tested is already showing 2 sector warnings (<500ms) and it isn't even to the 25% mark.



Our habit is to return such drives, as we depend on stable drives on which to mirror our client's data. Are we expecting too much from hard drive manufacture's?

In follow-up, all three drives failed. Each of them showing multiple sectors <500ms. I'm going to remap them and will be sure to watch those drives closely.

I had a change of heart and decided that we can't risk it. So, we sent the three drives back for RMA. We sent three new drives and got back three re-certified drives, all with the same slow read problems. I really am curious to know what you do when you encounter slow reads on brand new drives.

Typically I will ignore a few greens, but reds or browns even are cause for RMA I would say. With the exception that some drives always show a red on the first square, etc.

i dont use it , i send for a RMA.

Never know what can happen with the rest of the drive.

Yes the new sticker is not good....

Thanks,

It is just nice to know that I'm not being too fussy and have too high of an expectation for drive manufacturers.

Even though I dunno about the new 1 TB Seagate models, this problem seems to be common with Seagate HDDs. (slow sectors)

After some playing with the drives that show these slow sectors, I discovered that they are not consistantly slow. It is rare to find the same sector fail twice. So, as long as they stay in the <500ms and don't continuously fail, I'm going to continue using them.

how is it that MHDD detects a single block at greater than 500MS, when the software description states that it reads blocks in 255 packs? And how can MHDD accurately measure seek times considering it is used in a PC, which is subject to things like interupts.

well, interrupts can be masked if we want...
MHDD does not measure seek time, but access time for 255 sectors blocks as it issues verify command with that block size.
it might not be as accurate as an atomic clock, but basically it reports weak areas quite well, and that's the goal.

yes I meant seek time

and I get what you are saying, its a guide only and not 100% accurate

thanks

I would be pretty peed off if I bought three new drives and they were replaced with refurbs !!

Should have taken/sent them back to the supplier.

Agreed with Simba =)

IIRC, most HDDs I encountered lately with weak sectors have been Seagate. I would watch out for brown sectors, especially Seagate!

And the Seagate U-series may have this problem even more!
