Spare sector and reallocated sector number
March 4th, 2012, 11:01
hello i have currently two questions:
1)How many spare sector does a HDD have, generally. I guess every HDD model/brand/ has not the same number of spare sector. Where can one find this information, is it something published by manufacturers by any sort?
Where in the SMART/System Area wherever is it saved/ajust (i talk about the number of spare). For ex, with seagate serial cable and T shell, is it possible to read this value? how?
2)When SMART subsystem is reporting (05) reallocated sector count, where i can find the LBA of the remapped sector? Is this info can be reached into SMART logs? I think i've seen this info into SMART logs one time using hdat2 or mhdd. Is there a windows tool that can display the same SMART low level informations such as log and so on?

You have to learn a lot more about Hdd's and how they work.

Is that all you can say? Seriously you took the time to type on your keyboard to answer this? You have some time to lose?
Except that, any serious answer?

In order to see the G-list (Grown defect list) and P-list (Primary defect list), you need to send the drive a vendor specific command. These are proprietary commands that are not part of the ATA standard.
For example, here is a list of Seagate Diagnostic Commands:

Be very careful how you use them. They are case sensitive and can render your drive inoperable. They also only apply to certain models (F3 architecture).

This is like giving somebody a scalpel and a medical dictionary and allowing them to do surgical procedures....
The only difference is someones data and not someones life!
Of course its not good, but you just know people will try to DIY it. Whether because is cost, convenience or curiosity etc, the end result is the same.
