That's right, the partition the files were on was a fat32 partition, and I learnt later, that whoever mounted the partition. has ownership of those files...
Any ideas why this is the case? Intially, the drive was mounted by root, but even though I logged in as root, I could not change the permissions for hte files. HOwever, I logged out, logged in as a user, (with super access), unmounted the drive, mounted it again, and now this account owns the files!
