NTFS... Read Only ?

[brianjys]

Hi , Recently I just reformatted my mac as some old settings may have gone . so here's the problem , I'm been unable to copy things to my external harddrive as it is only can be read only. So is there anyway to change it to read & write because before I reformat my mac , it's able to read & write . PS : please don't ask me to reformat the external had to exFAT or mac formats because i have to use this hd on windows too. Thanks !

On its on OS X can only read NTFS volumes. Other software can allow it to read/write.

NTFS by default is read-only, you'll need software like NTFS for Mac for read/write ability.

By default your Mac can't write to NTFS. Is it possible you or the previous owner had installed an aftermarket utility like mentioned above, and by reinstalling the OS you deleted that utility?

it's not second hand and I got it from apple store so it's impossible to have 3rd arty apps install

Logically, either some 3rd party tool was installed, or your external hard drive was not NTFS formatted. There isn't any other explanation.

I would suggest reformatting to ExFAT, ANY Windows operating system >Microsoft XP can read/write to this, and I highly recommend it. (It is "FAT64" equivalent.).

Goodluck!
