can't read seagate 250 gb external hd

[webazoid]

I have a seagate external hd that was originally used in my dell computer. now that i've converted to mac, it can read but it can't write to the segate. any idea?

Perhaps you reformatted it HFS+? Windows has this thing about not liking HFS+ formatted disks. You can reformat it ExFAT with your disk utility program on your mac, that should solve this.

it reads/writes fine in windows. can read in mac but not write in mac.

It's probably formatted as NTFS. OS-X only reads, natively. I believe there are a couple of utilities that will enable read/write capabilities, but I can't remember the names.

Another option is to move the data, reformat the drive as Mac OS Extended (journaled) with GUID partition table, then move the data back.
