Windows 7: Format new HDD - quick or full ?

another question on this issue....where/how do you run chkdsk /f after formating....?...do I run from within windows at the run command ?

Is this different from checking both options on the Check Disk Options in windows under Properties/Tools ?

Thanks....

You open an elevated Command Prompt (run as admin) , type chkdsk /f and hit Enter. Command Prompt you find in Start > All Programs > Accessories.

chckdsk /f does not scan for bad sectors. chkdsk /r does. /f does file level consistency checks, not sector level. That is why it is much faster.

If you do a quick format followed by a chkdsk /f, as suggested, the chkdsk does basically nothing since there are no files after the quick format.

Maybe the moderators won't delete this reply from me in this thread since I didn't say anything about MS.

I was under the impression a quick format will wipe the partitioning table, and create a new one.
A full format will wipe the partitioning table, write zeros across the entire disk, then recreate the partion table.
So, when I need to recommission an old disk, I'd do a full format.
A brand new disk, sealed from the shop/factory would already be zero'd, so only needs a quick format.

A full format also scans for bad sectors, which is something you probably want to do for a new disk. You don't want to start laying data down if you have any bad sectors.

Zeroing out is relatively new (vista) for added security.

You are right in so far as on a disk with a lot of data, the /R option is the better one because it attempts to recover the readable data. However, on an empty disk, the /F option is sufficient since it disables the bad sectors.

I believe you are wrong, sorry. On an empty disk /f does nothing as it does checking at the file/MFT level, which on an empty disk there is none.

/R on an empty disk does a lot - it checks every sector and repairs bad sectors - exactly like a full format does. how much is on a disk doesn't matter so much with /r - its purpose is a sector scan, but /r does include /f.

This is from cmd chkdsk /? - But maybe I am reading it wrong.


/F Fixes errors on the disk.
/R Locates bad sectors and recovers readable information
(implies /F).

Yes, and indicates your mistake in your previous post. /f does not scan for bad sectors.
