I'm trying to format an external hard drive (Iomega 1TB) using Disk Utility but when but when I select
Format Volume or
Format Drive, it shows me the error:
Error creating file system: helper exited with exit code 1: Error calling fsync(2) on /dev/sdb1: Input/output error
I tried with Gparted too, but it doesn't find the drive.
Can anyone give me some hint? Thanks in advance.
P.S: I tried in Windows, but it doesn't work too. It says that I don't have write permission.
