A problem found when running a diagnostic on a media drive.
I recently ran a TechTool Pro Version 3 diagnostic on my media / video hard drives. I received the following error under Volume Structure: “File Thread Mismatch (1,24296)”.
I contacted TechTool and was told that “A file thread mismatch means there is corruption in the disk directories. There is inconsistency in where the file system thinks fragments of some files are located. This needs to either be repaired successfully or the volume reinitialized.”
My question, should my media drives be fixed, or is this fragmenting normal for a media / video drive?

You need to keep your drives as clean as possible by erasing them every chance you get. I erase my drives after every project if possible or at the very least every three months.
Defragmenting a media drive can lead to a whole host of issues with FCP where you can have have media “disappear” from a project.

Thanks for the quick reply. I am in the middle of three projects that are being incorporated into one DVD and have been unable to erase the drives.
Do you suggest I try and rebuild them using TechTool?
Thanks

[Howie] “Do you suggest I try and rebuild them using TechTool?”
I wouldn’t.
If it was me, I would run to the nearest Best Buy, Circuit City, CompUSA, whatever, and get a cheap firewire drive that’s big enough to hold all your media. Copy everything over to that drive, erase the original drive and copy everything back.

Do you know of any decent Copy Disk Cloning programs?

You can use either Carbon Copy Cloner or Psync. Both are free to use.

Howie,
You don’t need to clone your media drive. In fact, cloning the drive would do nothing but clone the current problem that is indicated Tech Tool. Just copy everything across, including directories. If the OS is unable to copy a corrupt file it should issue an error message.

Hi David
I have a Seagate 300GB FireWire Drive to back-up all of my media drives to. This drive came with back-up software. Do you suggest I use the drag and drop copying method or try this software?
Thanks

Hi Howie,
Yep, just drag and drop. Other than the fact that video files are relatively large, they are simple to keep track of compared to system and program files, which often require incremental backups and such. Don’t sweat it, you’ll be fine.
