aze 0 Posted July 14, 2002 Hello! (plz, don't note my bad writing, I'm Brazilian - I don't speak English) I'm looking for some information. I have a 40gb quantum Plus AS 7200 [ATA 66] running win2ksp2 (256 ram). All professional defragmentation programs I tryed (~4) dont defrag NTFS partitions cluster greater than 4kb [mine's 16Kb] ------ NTFS > 4kb cluster --------- good - fast speed good - less fragmentation bad - don't defrag bad - lost some disk space ------ NTFS <= 4kb cluster --------- good - can defrag good - don't lost disk space (relative) bad - lower speed (relative) bad - more fragmentation. ============================ C : FAT32 : 32KB CLUSTER : 2GB D : FAT32 : 32KB CLUSTER : 10GB E : NTFS : 16KB CLUSTER : 20GB <--- F : FAT32 : 32KB CLUSTER : 4GB G : FAT16 : 64KB CLUSTER : 2GB ============================ What cluster size should I set for NTFS part? And about MFT? What's the MFT function? What percent of the disk should I set for MFT size (12,5%? 25%?)? Plz, post your comments! Thanks! Share this post Link to post
clutch 1 Posted July 14, 2002 It's a limitation of the MS API that's being used by the defrag apps (Norton's defrag app isn't affected since they use their own APIs, but it is sensitive to service packs and patches from MS) and not the apps themselves. WinXP and .NET server don't have these issues because they have an updated API. Until you can go to either, I would suggest you stay with 4K, it's what I do. Share this post Link to post
aze 0 Posted July 14, 2002 Thank you for responding Clutch! Do u know were (if exists) can I download a 'patch' for this? When you refers to norton, you mean speedy disk? Share this post Link to post
clutch 1 Posted July 15, 2002 Firstly, there is no patch to address this limitation for the time being (unless you classify upgrading to WinXP or .NET Server a patch ). Second, Norton's Defrag util (Speeddisk) is the only one that will do what you are looking for. Personally, I would just backup all the data, delete the partition, then format the drive again but in 4K clusters, then restore the data. Share this post Link to post
aze 0 Posted July 15, 2002 thanks responding! I really could reformat the partition with 4k. But I need more performace information to perform this work. what about mft? Thank you! Share this post Link to post
