Drive reports 'write protected' or 'read only' 
when trying to save to or delete from it 

Discusses what to do if an external reports "Write Protected" when trying to save files onto it or 
delete files from it. 

A drive can sometimes report "Write Protected" when trying to save files onto it or delete files 
from it. 

This typically means that you have connected an external drive that is formatted with an NTFS 
partition to a Mac computer. MacOS cannot write to NTFS partitions and so will often indicate 
the drive is write-protected. 
Seagate GoFlex and GoFlex for Mac drives include an NTFS driver that can make the drives 
intercompatible between Mac and Windows, so that may be a good solution. 
See 

Document ID: 214531

 for more information. 

For all other drives, please see 

Document ID: 207851

 for instructions on reformatting the drive 

in MacOS. 

Reformatting the drive will ERASE ALL DATA on the drive.

 Please note that 

Windows partitions (ie, NTFS partitions) and MacOS partitions are not easily compatible at this 
time without special software, so using an external drive to transfer data between a Windows 
computer and a MacOS computer can be difficult and sometimes dangerous to your data.
