So I just got a WD Passport 320 GB external drive. I formatted it from FAT32 to NTFS using windows, and transferred some files to it. I then took the drive to school and discovered that for some reason i couldn't write to the root, unless i was moving over a folder. I thought it was a quirk, so i ignored it. at the end of the night I tried to back up my work, but it said it couldn't overwrite the files on the hd. I checked the properties, and every folder on the drive has a greyed out read only check-mark on it. I tried a couple times to remove it, but each time it just replaces itself. well I opened the properties of a folder I had taken off said drive, and it too had this read only semi-flag on it. but I needed to back up this folder, so I put it on my ipod which i had with me and use as another disk. I got home and thought maybe my computer could remove the read-only, like it was some sort of user doesn't have permissions error, but no luck. and now, my homework is read only. any ideas on what i did/ should do?
EDIT: Both Machines are using WindowsXP Pro, I'm using SP3, school is using SP2 I believe.
Edit 2: Apparently despite having the read only flag, my home computer has full access to the drive and can overwrite any file, and write directly to the root. any ideas as to why i don't have that level of control with my school computer?
