ntfs 4kb or 512byte chunk size here?------>>

[Pilsnerpete]

In w2k, how do you know the size of clusters (is it?)? I want to use 4k chunks, for better performance, but I read something about how it uses 512b in a certain instance. Don't remember where I saw that...

So, I'm wondering if the format command in the recovery console (f8) formats the drive with 4kb or 512b blocks. Anyone know off the top of your head? Thanks

Run chkdsk from the command line, it'll tell you the cluster size.

If your NTFS partition was converted from FAT32, it will be 512 Bytes clusters. However, if it's "native" NTFS, it'll have 4 KBytes clusters (the default and more efficient choice). You cannot convert from 512B to 4K without reformatting the partition.

Thanks, guys! Especially Zucarita. That was Grrrrrrreat! So any time--except when converting fat32-ntfs--it spits 'em out at 4k? That's good news. Now just to check if Asus has the newest nForce drivers...

Partition Magic and Partition Commander will both let you change the chunk size.

too bad I didn't know that 2 days ago!! just ordered an OEM version of Drive Image. $30 seemed like a good price compared to the retail of $70(!). Coulda saved on shipping.
:frown:

I forgot I posted this one. Thanks, M.R. Burns. and Nothinman! Is "allocation unit" what I was referring to as "chunk"? Now to use the new word in a sentence:

Mr. Burns got so drunk, he blew allocation units all over the floor.

Yes an allocation unit is a 'chunk' or 'block' or 'cluster'. block is commonly used in unix and VMS terminology and cluster is common with Windows, but they all really mean the same thing.
