External IDE hard drive formatted FAT32. Connected via an IDE-to-USB adapter. OS: Windows XP

Tried two different adapters (different manufacturers), same results. Reads fine in bursts of ~500MB, then the entire machine (Explorer, apps, etc) all hang for about ~2mins. Copying then resumes again.

Same behavior whether copying lots of small files (1-2MB) or large files (> 1GB). Happened with three different drives so far, ranging in size from 6GB to 20GB.

Any ideas on what's going on here, or how to resolve it?

This issue does not occur on NTFS formatted drives.

@RandolphWest: That's my own post. And it's not the same issue, since this behavior is observed with or without write caching. –  Unsigned Oct 15 '11 at 18:04
    
Audio is enabled and no "ding" from USB disconnect/reconnect? –  horatio Dec 30 '11 at 21:05
    
@horatio - Correct. It's not a connector issue. –  Unsigned Dec 30 '11 at 21:06
    
I was thinking power actually. External power for HD? –  horatio Dec 30 '11 at 21:10
