  1. Update: It's a little worse than I thought. I tried to just move all the avi's off onto other large drives. A fraction of the files have CRC errors; they were corrupted. As far as I can tell, I can only move off non-corrupted files, and will have to re-generate all the files with corrupted CRC's. That involves a LOT of time. This will not be done in the near future. I really thought that couldn't happen....
  2. Hi. I've been using Defragger for a while now, and love the ability to defrag individual files. Most tools are set up for a desktop computer, not a video server, and although they work, the parameters may be a bit less than optimum. I think thats the case here. I was setting up a video server drive for a dedicated video server box. It runs a small Linux kernal off ROM, and mostly just plays MPEG or AVI (Divx/Xvid) files on demand. It doesn't do much else except copying files or acting like a really big USB drive. I am using a 1.5Tb Seagate drive with 32M cache (more than it needs cache wise), and set it up as a secondary drive on a desktop computer just to format the drive and copying files. I formatted using the Seagate utility (I think it's written by Acronnis) just fine, but used standard single drive parameters. I copied about 1 Tb of files from other drives attached to the desktop. Everything went very well as I copied from a single source at a time. I was over 800Gb with no fragmentation at all. Then I got lazy; I copied from two drives at the same time. Sure enough, at about 1Tb, I had some minor (5-10%) fragmentation. Since I was about to move the drive to the video server, I decided to defrag the drive now as I would not have SATA acess in the server so a defrage on a big drive like this would become hopeless. That was a mistake. The better move would have been to move any fragmented files off the drive again, then put them back one at a time. Defragger went about it's business just fine, but after about 3 hours we had a re-start of the desktop (not due to defragger) long before it was done. Oh-oh. After the re-start, the files all appeared intact, but Defragger now claimed the drive was 50% or more fragmented. Half red, with some blue scattered here and there. It also appeared to have a larger MFT (?!?) than before (but I have to admit, I hadn't paid much attention to the size of the MFT before) and I have no idea how that could happen. On a 1.5 Tb drive, even a 12% MFT is over 160Gb. On a video server you don't need more than probably 20Gb MFT under any conditions I can imagine; a 2 hour Xvid file is only about 1.5 Gb, and you can only play one at a time. I stated Defragger again, and after 3 days I am only 15% done (this is a dual-core machine running over 3GHz). Eventually, in about a week, I may finish. At this point, I'm thinking of using two 1 Tb external drives, writing all the files out to them, and reformatting. Any other ideas? If I re-format, should I try and make a smaller MFT? How would I set that up? Any ideas as to what is appropriate? This probably should just look like a really big USB drive. I really did myself in this time! Larry
