Wavs have a second of static

A new problem has popped up. Whenever I play wavs there is a second of loud static, usually at the start of each clip. The MOV audio all play fine. Sometimes the sound dips out for a second or other tracks play in the background seconds before they begin on the timeline.
I'm at work and don't have my specs at the moment. It's Windows 8 (I think). I have the latest vegas update, tried a fresh reinstall, removed the audio driver and rebooted. No plugins. Rendered audio likewise has the glitches. Sources are all clean.
Thanks.

Does the clip(s) start midway through a waveform cycle ? Will give a click and maybe overload DA. Try a 20ms fade-in, or start at a zero-crossing.

If it happens anywhere within the file when initiating play, try adjusting the audio PB buffer.

I moved the data from a hitachi to a seagate external and now it works. Something about the hitachi vegas didn't like.

I have exactly the same problem with projects located on a certain external disk. Whether it's the disk itself or its USB nature, it would be good to know the cause. In my situation, the misbehaving disk is a 4 tb Seagate external. Other symptoms can include continuing periodic blasts of loud static as well as periods of total silence. The projects themselves seem fine. If I copy them to another disc they play perfectly.

I ran into this problem with a Buffalo 3 TB external drive, Vegas Pro 12, and uncompressed WAV files. I have another Buffalo drive and a Seagate 5 TB drive that don't cause problems. The wav files are of songs ripped from a CD using Vegas Pro 12.

I didn't experience problems with Wav files ripped from CD's created years ago with unknown ripper.

I changed drive letters, swapped cables, swapped ports, etc.. There wasn't anything I could do to make the Buffalo 3 TB work with Vegas Pro 12 and uncompressed wav. I copied the files to various drives and compared them with the DOS FC command. There were no differences.

To get around the problem, I used subclips made in the trimmer from the problem wav files. I didn't trim anything, just set the in and out markers to the entire range and then clicked the create subclip icon. I dragged the subclip from the project bin to the timeline, and it played back perfectly.

UPDATE: The Buffalo 3 TB drive was formatted incorrectly. Somewhere along the way I incorrectly formatted it as MBR instead of GPT. After backing up the data onto another drive, I tried using a partition manager to change the MBR to GPT, but that didn't help. Next I formatted the drive using Windows Disk Management, but that didn't work. Finally I found online the appropriate Buffalo formatter utility to format the drive, and that fixed the problem.
