How long should it take to zero an 80GB drive? More than 25 min? - mattkime - 10-03-2006
How long should it take to zero an 80GB drive? Its been 25 minutes and the blue thermometer isn't at the 25% mark yet.
I suspect this drive is garbage.

It takes a long time. I zeroed my 60gig drive on my powerbook before I sold it, and it took a couple of hours for three passes.

hours. maybe even overnight if it is an 80GB laptop drive.

its a desktop drive.
grar. zeroing is a good way to verify a drive. client is getting that at this hour.

I have had 2 drives be bad from Apple in new machines. They installed the OS over the bad sectors.
Since then, I wipe, and zero all drives before I put them into use. it took months to figure out what the problem was.

Zeroing writes zeros to the entire drive. 80GB of zeros.
How long would it take for you to copy 80GB of data? A couple of hours? More?
Leave it overnight.

it takes longer than just writing 80 gigs of data. not sure why.

'Depends on how you're doing it. It could be writing zeros 3x or 7x or 11x or 35x...

i was only zeroing once. i'm not sure why it was taking so long.
writing to sectors should, in thoery, map out bad sectors. i think the "write zeros" option does something more intensive to get rid of the intermitent blocks. or maybe thats just what it feels like.
...installing OS X combo update....can't wait to go to bed...

I think it is a read, write, and read back to each sector. (old SCSI and OS 8 days at least that is what the surface verify did)
