Just reformatted my hardrive to NTFS from FAT 32, now I have

[eprunner06]

I formatted my hardrive from FAT 32 to NTFS and now when I captured I get tons of dropped frames. Just to make sure that the NTFS filesystem was the thing giving me the problem I formatted back to FAT 32, and now I dont drop frames anymore. Has anyone ever heard of this?? Any suggestions for getting my captures to work with NTFS. FYI, I used "quick format"
Please help
Thank you

I have been thinking of doing the same thing, but it might be the NTFS file system is slower than FAT, especially if the clusters are small. For video, the bigger the clusters, the better performance.

my drive is a little over 20 gigs, is that small? It is actually a "virtual drive" that is part of a 30 gig 7200 RPM hardrive.
Thank You!

i have a similar problem with a medea video raid system that i recently formatted in ntfs. i can capture for like 10 minutes, then i get a dropped frames report. this never happened b4, and it certainly shouldnt be happening.
would fat32 likely fix this?

I would say that its worth a try, however as you probably know, if your formatting the hardrive that windows is loaded onto, you have to know what you're doing to load it back on. If you have a seperate hardrive for video captures, I would try it.

at least in FAT32, i'm pretty sure that the first partition is given the outside (faster) part of the disk. so if you want to make a 10 and 20 on a 30G disk, make the capture partition first. and FAT32 is supposedly faster especially when you pre-allocate the capture file. most of the performance problems are from the heads seeking back to update the FAT when they should be writing.

and if you have a 7200 RPM drive, what exactly are you capturing that you can't keep up with? i don't think your disk should be a bottleneck at DMA66/100 unless you're doing huffyuv or another nearly-uncompressed capture.

if you reinstalled your OS it might've been how you managed the disks instead of the filesystem though.

[eprunner06]

No, I didnt reinstall the OS, but the capture partition is second, and I am capturing in HuffyUV. So you are probably right.

Hello,

I'm not sure if this helps or not. My system utilizes 2-45GB IBM 75gxp drives configured as RAID0. The RAID card is a Promise FastTrack ATA100. The drives are formated NTFS. Using this setup, captures can be done full frame with 0 drops using Huffyuv (or many other codecs).

Here are some items I found that help:
-Any SMART features must be turned off
-UDMA must be turned on in Win2K device manager
-RAID drives perform best when they are of identical make/model.
-VIA based systems must use Win2K SP2 and the latest 4-in-1 drivers.
-Turn off performance counters.
-Capture to a non-OS partition.

that's a good point too, that SP2 must be installed. but when i used the latest VIA 4in1 it changed my drives to SCSI in device manager as it installed the VIA BusMaster Channel. the drives worked ok, but the cd-burner wouldn't. so i switched the IDE controller back to the one it was originally, and everything's fine.
