pending sector-should i split the hdd into partition before

[nav5]

i have a 3TB hdd that have "reallocate sector" ,"pending sector" ,"uncorrectable sector" warning
and i want to format to reuse that disk (to store unimportant data)
(i read from an website that says write full zero to hdd can reallocate the pending and uncorrectable sector,so i want to use windows format function to do that)

but the problem is the capacity is large so the format process may take long,
so i think maybe during the format process, if there is any problem , i would have to reformat the whole drive again,
to avoid that ,i intend to split the hdd into many partitions, each partition size about 100gb and format one by one (if there is any problem,i only have to reformat that partition)
but i 'm not sure splitting the hdd into partition and format one by one like that would cause any problem
(in comparing with format the whole drive)

If those pending sectors are out of the partition space that you are writting to then they will not be written/tested and will still be on the pending list.

Hello, thank you very much for the very detailed answer and the advice,i really appreciate it
i already copied the data to another drive,i know it has so much bad sectors and i just want to try a test with this drive for experience,i can use the computer during the format process so it 's not a problem
about my question ,to confirm it again that means if i partitioned the drive with no unallocated space,then format one by one, it will make the same result like i format the whole drive, right ?
Thank you very much:D

i see , thank you very much for the help , i really appreciate it
maybe i'm lucky ,it seems that there are no pending sectors in LBA
after spliting into partiions and format , there are no pending sector count , the reallocated sector count now also decreased to 1972
Thanks so much
