Vista - O&O users: I have a question

I am using O&O 10 pro. I have a fresh install of Vista x64 on a Raid 0 (2x150GB Raptors). I have run defrag in Space and Complete modes a few times now. Yet every time I run it I still have 50%+ fragmented files on my Raid. When I had Vista intalled on just one Raptor before, O&O would take it down to 0.3%. Is there something wrong? Or is this how O&O reads Raid 0, even after defragging? I have exhausted Google queries looking for an answer to this issue.

Any help will be greatly appreciated. Thanks.

Is your paging file on this RAID 0? Try doing an offline defrag. It will do system and paging files properly.

I believe it is, since I did not move it to my sensitive data storage drive. I will try offline defrag tonight. See if that helps.

I did a massive program reinstall since reformatting. I should have run defrag in between a few install batches.

I have tried O&O and have numerous problems with them. Not on a RAID system though. Then I went and tried Diskeeper x64 and Perfectdisk x64. They seem to work much better in comparison to 0&0. Sorry this didn't answer your question but I thought maybe a few alternative might be worth your time.

Yah, I had used O&O for almost a year on my previous Vista install, seemed to work on just one drive.

I did the offline defrag in O&O, after doing so, "check drive" found a chkdsk error. There wasn't an error before, but now there is after O&O just defragged the files it was supposed to optimize. Go figure.

Anyway, doing a trial of Perfect Disk right now. Seems to work better...at least it gives me peace of mind right now. Perfect Disk seems to leave a lot of chunks of free space, as opposed to a few large chunks. I thought it was supposed to optimize that?

Gonna try Diskeeper on next defrag run.

Hi Blackjaw,
Diskeeper 2008 Pro and Pro Premier editions support RAID as well as Vista 64-bit. Please do download the free trial versions of Diskeeper (current build is 781) from the downloads section of our website http://www.diskeeper.com

I used Diskeeper for years. Beta tested with them. I left them. I was not happy with the product. It was slow and not optimized very well. The algorithm did not do a great defrag. Perfect disk had issue with firewire drives. I found O&O was the best.

Thanks for the replies.

I wish O&O still worked correctly on my current install, I like that program. But when I did the Vista CHKDSK sequence, O&O did not find errors. When I did the offline defrag in O&O, all of a sudden I have CHKDSK errors. Didn't bode well with me. Anyway, I may investigate this problem further when I have some time.

No worries here with firewire drives.

Eventually I will test Diskeeper.

I would run chkdsk c: /r from dos prompt and reboot. I had the same issue. It was a hard drive going bad.

I am actually working with a higher up at DisKeeper who has put me in touch with a developer to get a few issues that I experienced with DK to make it work better, as well as making sure it is compatible with 64bit versions of Vista.

When I get some new info I'll pass it along.

(Be sure to remind me if you haven't heard anything from me in a month or so....the dev is actually in China presently so we're at a standstill....)
