Can't Transfer Files to External Hard Drive Anymore

The only solution I have found is to have the external HD partitioned between Mac and PC. To copy drag to Mac then drag again to the PC Partition.

Hi good day, does anyone fix this without reformatting, My disk are NTFS, an always been capable to write data on them, yesterday I installed tuxera and start copying files, suddenly the power went out, so when I wanted to write the files again, I saw it has that restrictive acces to the disk. ¿how come it was working on the first instance? and then isnt?

have a great day if anyone can help. preciated that!

Power cuts can leave a hard disk in a state that needs to be repaired. This is may be more likely on a NTFS disk when used on a Mac (due to how the drivers cache & write data slower than supported disk formats).

I suggest you connect a different disk that is NTFS format to see if the Mac can read & write to that disk normally. That will indicate if the Mac is at fault or if the original disk is at fault.

Then verify the original NTFS disk on another machine, ideally one with native support for NTFS (so that it can repair the filesystem if required).

You can also try reinstalling Tuxera, if it is not loading.

Thanks for your reply, already did that, missing the test on another machine I let you know.

But I was writing and reading last weeks. Dont know what happen, same on another drive that wasnt disconected when the energy seizure happend.

Finally got home, after reading and installing and uninstalling many drivers for NTFS, i conect via rj-45 inverted cable, a windows laptop and my macbook, via athernet, set up network, and was trying to pass files via network, windows machine crached on so knowed blue screen. Before that I deleted the incompleted tranfered folder, and rename the volume.

I let the windows laptop behing and plugged again the win NT NTFS drive. so it worked again, is tranfering like a charm via usb.

I can't really tell how this goes Im not that geek, but wish I could be so I can give more detailed information whom having the same issue.

are installed macfuse, fuse for osx, and NTFS-3G

enjoy!

I just reinstalled Yosemite on my MacBook Pro computer and suddenly my Seagate External Hard Drive quite working. I used to be able to read and write but after the reinstall it was showing "read only". Also the hard drive still worked perfectly on my wife's MacBook Pro. I reinstalled the driver from Seagate and it fixed the problem. Here is the link to the driver, http://www.seagate.com/support/downloads/item/ntfs-driver-for-mac-os-master-dl/Good luck to everyone else, hope it works for you.

🙂🙂🙂 it worked

THE ANSWER TO YOUR PROBLEM IS RIGHT HERE!

I had the same issue. One of the posts were correct in that, Mac is typically unable to write to a hard drive that is NTSF formatted, HOWEVER, on the Toshiba external hard drive that I purchased, there was a software called Tuxera NTFS for Mac. It was inside of a folder titled Mac Driver. If you have this on your hard drive as well, all you will need to do is install the software on your Mac and you will then be able to write to your hard drive. After you install the software it is recommended that you restart your computer, however, in most cases, if you unmounted the hard drive and reconnect it, it will work.

Hi all

I had this problem this morning, I guess because I just updated the operating system to something like OS Capitan or whatever it's called... When I connected my hard drive I was asked if I wanted to use it as back up just like it did the first time and like the first time I said no. Somehow the drive is now NTFS with no option to change permissions, and was NEVER used to write from Windows.

My hard drive being a Samsung, I found this piece of software that sorted everything pronto. Although I found it on the samsung/seagate website, I don't think it's specific to the brand and will allow your mac to write on NTFS:

Hope it works for you, if not maybe check if your hard drive manufacturer has something similar.

Failing that, you'll need to transfer the content of your hard drive somewhere else temporarily and format it to Mac!

You can avoid the need for third party software to read NTFS disks simply by formatting the disk as Macintosh OS Extended. It allows the data to use all of OS X's filesystem features - it's best for Mac users.

Third party NTFS drivers have caused issues on previous OS updates - sometimes the developers do not stay up to date with how the OS works.

Drives do not 'reformat' themselves & an OS X update will not have done that either. It seems more likely that the disk shipped as NTFS for PC support - many suppliers pick a format compatible with Windows as a default and you have only just noticed. It's also possible that you already had an old NTFS driver that stopped working after the update. Macfuse, NTFS3G or OSXFuse may have done that. Without knowing what OS you updated from it's hard to say.

For what it is worth OS X only has read support on NTFS - it has always been that way, you probably had other drivers installed on the last OS.

Hey Drew

I know I can reformat the drive, the whole point of installing this piece of software was to avoid doing that, as I have tons of pictures on that hard drive that I wouldn't know where to 'park' in the meanwhile - and it would probably take me a couple of days! I'm a photographer, filling hard drives like they're USB sticks...

I updated from the latest version of Yosemite to El Capitan and yes, I just saw there was a previous version of the same software which obviously stopped working with the OS update. So if anyone is having this problem and not wanting to reformat, I guess the answer is to check for an update of your hard drive driver which is already in there somewhere!

The hard drive is a Samsung M3 which I bought at the same time as my Macbook not too long ago and being totally new to Mac I just set up as recommended on the manual - i.e. using the software included. I've been happy with it so far.

Shall I decide with the next one to format straight out of the box to OS Extended, would it be a problem reading from Windows? Not everyone I work with is a Mac user... I really hate this whole Mac/Windows thing! CAN'T WE ALL JUST BE FRIENDS??? 😢

Thanks for your help!

Mac & PC are different. They need different disk formatting, you will require additional software to read & write one format from another OS.

Personally I avoid NTFS on Mac as much as possible on a Mac, if you need to use on a Mac & PC make sure you have additional copies of the Mac data on a Mac formatted volume is my advice. Certain apps (like iPhoto) save data that requires OS X specific file system features - it can break the data on NTFS disks etc.

It sounds like you don't have enough space to backup this disk - one copy of any important in files is a bad idea.

The video was helpful but not because I followed the steps to reset my driver! I instead read the comments and found this gentleman offering the Tuxera App for Toshiba drivers. All i did that download that software he offered through dropbox and now my Toshiba Driver works again!

Try it if you have a TOSHIBA DRIVER ONLY: https://www.dropbox.com/sh/0sa86kro55hr1br/AAAWRNNnWKgM5nJ9j5OS5esXa/Tuxera%20NT FS%20for%20Mac.dmg?dl=0

Thanks chikizz, had the same problem as others on here today, followed your instructions, back to normal now, again thanks.

I had the same issue, and here's what worked for me, did not require reformatting, and you might not need all these steps.

(1) ensure that my external disk is formatted for Mac, not NTFS.

(2) use the Disk Utility to "Verify Disk" - it found some errors! Then click Repair Disk. It healed itself in 10 minutes. Nice but still I can't write to it.

(3) Finder, select the external disk, GetInfo (cloverleaf i), SCROLL WAY DOWN to see the lock, unlock it.

(4) Select that guilty-looking read-only, change it to read-write

(5) if you see "error code -8076" it's because you're at the root folder. MAKE A SUBFOLDER and redo step (4)

(6) Now can you save your winclone bootcamp backups to that folder? If yes then treat me to Starbucks 🙂
