erasing hard drive so it is "as new"

hi,
i'm selling a hard drive from my macbook and want to make sure that when i've erased it, it will be as if the drive was bought new, so it will work in whatever computer it is put in.

i've already deleted everything on it, in the MS-DOS (FAT) volume format, using the 7 pass secure erase option, just because i assume there's more chance of the winning bidder on ebay being a windows user than a mac one.

was this the right thing to do though? because now i'm thinking maybe the drive won't work if the winning bidder has a mac! i'm pretty rubbish at this kinda thing so if someone could shed some light on it, that'd be mint

oh, also i notice at the bottom of disk utility, where there's all the drive info, it says 'partition map scheme: apple partition map,' even when i made sure i deleted any partitions on the drive before erasing. that seems a bit worrying as i don't know if a drive with an apple partition map would work in a windows computer. although having said that, it has just begun its 6 hour job of erasing, so maybe it will automatically make a new partition when it's done. like i said, i don't really know what i'm doing

hope someone can help, thanks in advance.

oh! ok then, i'll wait for it to finish formatting then send it away! thanks very much

 

how do i do that, millar876?

 

anyone?

 

i did read, but i don't know how do do what he said. i can't find a way to make it windows partition mapped.

 

hi, i understood that, but there was no fat32 in the drop down box.

i've just realised that i had to click options at the bottom and change it to master boot record, and then fat32 appears in the drop down box when i click it. told you i was clueless!

earlier i deleted the partition from the drive completely, and now in the left hand list of all my drives, this particular drive has nothing underneath it anymore. is this how the drive would be if bought new? or do they come with an MS-DOS (FAT) partition as standard?

 

i'm sorry to have to keep bumping this thread but i'm kinda in a hurry...

in disk utility, i deleted the partition that was on the drive, and now it looks like this:

is this how the drive would be if it was bought brand new, or should i make a partition, or format it, or what?

 

great, thanks very much
