Hello, I use both Mac OS and Windows. In the past, I also used Linux. Some of the files created under Windows and/or Linux have very long names and some of the files are also written in Japanese. Could you please let me know the following? 1. If I buy a 3T-4T drives to back up my current MBP and also to backup of previous backups (don't want to carry lots of small capability drives), which format should I use to format the drive? I remember that in the past, sometimes during copying, some files could not be copied due to long file names and/or size. 2. I just connected a 2T FeeAgent GoFlex to my MBP. I used it about a year ago. For some reason, I cannot create a folder nor delete an empty folder. Do you know what is going on? Under Access rights, it says that it is read only! The file format is NTFS. Thanks.
