I am running a laptop with WinXP Pro SP2 and have been having problem with a Speeze enclosure using the Prolific 3507 combo controller. I have tested it extensively with large video files that I was working on in Premiere and found it to corrupt the NTFS partition information when connected via firewire. I could not recover the partition table when this happened I recovered the data using GetDataBack for NTFS and reformatted the drive. This has happened 3 times using the firewire interface, and seems to happen under extensive IO operations. Since, I have formatted again and am using USB 2.0. It has not had any problems yet though it is a little slower with this interface.
I have searched all over the net and can't find a solution to this. I also have a TDK Indi DVD writer connected through firewire and that hasn't been a problem.
The drive is a WD 200GB 7200 rpm.
Open to suggestions.... I finished making a DVD of a wedding that was filmed so I can now afford to lose the drive.... again :-(
