How to format RAID NTFS partitions?

6 posts in this topic

As the topic says. I've tried Partition Magic 7 Pro, it doesn't work for me. Is there some other software out there that will do it?

I want my RAID Array to be 64KB NTFS Cluster sizes and the other backup drive to be anything <4KB. Currently both are default 4KB, which is not ideal for me. I have Highpoint 370 RAID Controller. (120gb in 2x60 + 60gb stand-alone)

Thanks in advance,

I just downloaded Paragon Partition Manager which appears to be reading my RAID drive. Although I get an error with Disk2, whatever that means. All my drives are represented correctly so I dont know what that error means.

Can NTFS cluster sizes go upto 128KB? I thought the max was only 64KB.

I'd delete this thread if i knew how. I've solved all my problems now so no need to get any help.

I found a way in windows to format to 64KB cluster size. (Must go into Admin.Tools, Disk Management) otherwise normal format only supports upto 4KB sizes.

End-of-Thread :)

Using Windows Explorer, you can also choose to format a drive by right-clicking the drive. However, Windows Explorer will only format at 4 KB cluster sizes.

Erm..

cmd.exe
format E: /FS:NTFS /A:size

/A Overrides the default allocation unit size. Default settings are strongly recommended for general use.

NTFS supports 512, 1024, 2048, 4096, 8192, 16K, 32K, 64K.

FAT supports 512, 1024, 2048, 4096, 8192, 16K, 32K, 64K, (128K, 256K for sector size > 512 bytes).

FAT32 supports 512, 1024, 2048, 4096, 8192, 16K, 32K, 64K, (128K, 256K for sector size > 512 bytes).

Note that the FAT and FAT32 files systems impose the below restrictions on the number of clusters on a volume:

FAT: Number of clusters <= 65526 FAT32: 65526 < Number of clusters < 268435446

Format will immediately stop processing if it decides that the above requirements cannot be met using the specified cluster size.

NTFS compression is not supported for allocation unit sizes above 4096.
