Seagate Barracuda 7200.11 ST31500341AS - Reallocated Sectors

September 16th, 2017, 8:46

I have several questions about this HDD and reallocated sectors in general.

It seems that the maximum raw value of reallocated sectors that can be seen in SMART-Data is 4095.
Does this mean that no more than 4095 sectors can be reallocated or is this just a false information of SMART-Data if more reallocated sectors exist? (Even some smaller or bigger Seagate drives seem to have this maximum value of 4095 in SMART-data).

I have read elsewhere that normally a HDD has 0,01% reallocatable sectors and up to 20% of these sectors are used directly after production of the HDD for the p-list?
Is this correct?
The ST31500341AS (1.5 TB) has 2.930.277.168 sectors, so it should have over 200.000 reallocatable sectors for the g-list?

Hello,

yes, it is true, Glist has a capacity of 0x1000 entries on this model. But believe me, it is already the begining of the end when it gets full, the drive will not last much longer.
