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.
