i started my computer up this morning and noticed a problem on my 1tb wd my book external. i have a rather sizeable collection of music and movies, split into 18 folders, each containing roughly 20gb of media. i noticed this morning that one of the folders was much, much larger than it should be. after some digging i found the location of the problem, but i have no. idea. at. all. how to remove it. i included a screenshot - it appears to just be junk data, but i'm not certain about that. i tried using a program called Unlocker to delete the junk data, but it failed, even when i ran it at startup. i don't have enough money to go out and buy a new external, so if there's a way to fix this i'd really appreciate it.
if it matters, i'm running windows xp on a gateway e-series tower, 2.6ghz p4 ht northwood processor, 1.25gb ddr-400 ram, 40gb system hdd.
