I am sure this is a simple question, but I am having a problem going from windows to mac with an external hard drive. I can read and write to the drive on any windows PC. On my macbook pro laptop, I can only read. It will not let me write or erase anything to the drive. Does this have to do with the drives formatting? If so which format will let me both read and write on mac and pc?

I've had a 1TB external hard drive for the last year and never had a problem with it until now. Suddenly, it is showing as read-only, however, it's formatted for Mac. Do I have to re-format it?

For some reason my Lacie external drive that's hooked up to my imac is constantly being read for no reason. It's never idle and never rests until I eject it. I'm afraid the drive's gonna fail soon and all my work gone? Did a search but can't find anything online.

I recently borrowed my brother's laptop to use as a media station for listening to music from, and watching movies, in order to free up some space on my main macbook. In trying to migrate some files over, I discovered that my hard drive, a 320 GB WD Elements drive, is having some problems which I've never encountered before. It has always worked fine in the past, but now I can't transfer any files to or from it, from either computer. In all of my troubleshooting, I've gotten various errors, (-36, -50), and various messages saying how the device can't be read or written from, or how some files contian unreadable data, etc.Disk Utility found an unused node when verifying the disk, and notified me that the disk needed to be repaired.I then used Disk Utility, which said it was able to successfully repair it, but the same problem remains, and after verifying the disk, it still says it needs to be repaired.I've tried to find any files that may be causing the problem, and was finally able to delete a seemingly troublesome file that was stuck in my trash bin from the external drive after trying various apps, (ie Trash It, Cocktail, What's Keeping Me?).This didn't end up solving anything...I've used terminal to eliminate some other potentially problematic files, with no luck still, and I'm not too confident with Terminal so I don't want to be messing around too much without more guidance.
I've used Disk Warrior to try to solve the problem, but still with no success.When I use the app to Check All Files and Folders, it does so for only a few seconds, then reports that "An unexpected error ocurred while attempting to perform file operations" for several files, and that several files' "Property list is damaged and cannot be repaired". When using Disk Warrior to REBUILD the drive, the app pauses for about 15 seconds, then says that it can't be rebuilt because it is in use.Again, I've used the What's Keeping Me? app to kill any activity with the drive, and the same error occurs.I've spent a lot of time trying to sort this out.

My external hard drive has reverted back to it's read-only form after a few weeks of running fine using tuxera so I can use my hard drive with my mac. Now tuxera or similar programs don't even recognise the drive.

I bought a Seagate Free Agent Go Flex External drive. I transferred all my files from my previous external HD.
When I went to access my folders on my external HD, the folders are all locked, with Sharing and Permission section in the Information "Everyone: Read" only! I can't change any of the information or move things! All of them are locked and "read only." I know how to change it, but only manually, individually. I have several hundreds of folders and I don't want to manually change all of them to "Read & Write." Is their a way to let me re-set the folders to "Read & Write" easily??

Ok so I have an 8800 GS imac, 3.06 intel core 2, 4 gigs ram. Running snow lepord. I need to resolve an issue where I can not get into OSX. At first I got error messeges saying my external HDD could not read, now it looks like its my primary drive because when I restarted I got the progress bar under the apple logo, indicating that something is wrong with the OS. The bar when to full 100% but then I got stuck at never ending spinning wheel. I restarted and no more progress bar but still the spining wheel of death. I really dont mind refomrating its just that I had some important text documents and other files that I cant get back without recoving them some how. How to proceed? I held down cmd v or s (i forgot) on startup and got a black screen with several problem statements. One reads the system boot strapper has crashed trace BPT trap.

my External Seagate Hard drive just changed to read only on its own?
I went to get info and scrolled down to the Sharing and Permissions
But there is nothing there but a greyed out : You can only read
There are No boxes to check or uncheck, No options to change to read and write, No name of owner or ignore ownership box. NOTHING ELSE IS THERE
I have recently upgraded to Mountain Lion and am having other problems as well

I have used a Samsung HX 1Tb external hard drive under OSX Snow Leopard with absolutely no problem. Since I upgraded to the free (improved?!?) OSX Mavericks my Macbook Pro cannot "see" my hard drive. All I get when I plug it in is the following message -
my MacBook thinks that the hard drive is formatted for windows - but why should it work OK under Snow Leopard but not with Mavericks? I don't want to simply reformat the external drive because I'll lose all the files stored on it.Is there suitable software/Apps that I can use to let my Mac access this external hard drive.Incidentally my partners new Macbook Air can still read this hard drive.

How do I transfer video files from one external hard drive to another external hard drive? OS X 10.9.5. I opened up each device in a finder window and tried to drag and drop from one device to the other. No luck. Next, I R-clicked on the file and requested to copy it, then R-clicked on the Finder of the destination drive, hoping to paste but that option did not present. I am able to paste a file onto the desktop from the original location but I cannot move it from there onto the destination drive. Full disclosure: I began this operation using a Windows laptop with no difficulties. Both drives are dual formatted. The destination drive is 2 Tb and has 1.5 Tb remaining space.

I used my external hard rive for installing linux(ubuntu) in my other machine. Now when I use the hard rive in mac os or windows, it does not respond very well. When I use windows for transferring files, it shows 1Mbps transfer rate. But it used to have 25 Mbps transfer rate in windows. Now when i use this drive in my mac, it does not show anything. I then used disk utility to reformat it to Mac os x extended journaled, it just gets stuck in Mounting..... like forever. Is there any way to reformat it Fully (i mean "fully" to remove the core files and rebuilding the system files for my external hard drive)) by using 'terminal' or disk utility? Is the hard rive hardware damaged(but the file transfers in windows though slowly? My external hard rive details are:
1.WD external
2.USB 2.0
3.size: 1TB

I have a western digital hard drive that had previously been working flawlessly on Lion, however when using it with Mavericks it had suddenly stopped working meaning it would no longer be found on the desktop or in finder. I have been using the hard drive as a time machine backup. the obvious next step was to launch disk utility and look for a solution. I have found there two hard drive names in disk utility, the first is the HDD name of Western Digital and the second is the "Time Machine" partition. Running first aid on the partition resulted in an error and that the disk could not be repaired. This HDD is important and the data cannot be lost.

I've got a 2011 macbook pro, 16GB RAM and 500GB Hard Drive. I'm wondering if it would be possible to buy a 1TB external hard drive and partition it in half, and have 1/2 be a bootcamp windows 7 partition and the other be a time machine backup for the mac hd.

Why does my external hard drive back up on time machine ok, but when I enter time machine (and the external device isn't plugged in) i can't see it?
It appears in time machine fine when the external drive is plugged in, but just not if it's been ejected or
I want to have the ext drive backed up in case I lose it or it corrupts....and if that happens I won't be able to plug it in to see the drive in TM - does that make sense?
I am running OSX 10.9.3 on a Mid 2010 Mac Book Pro. The external drive is a samsung and is formatted to Mac OS Extended (journaled). Time Machine is a standard Apple one and has been working fine for a couple of years

My external Hard Drive (Western Digital 2TB hard drive in a ICYBOX 2-bay USB 2.0 HD Dock) won't transfer files to the Mac HD. The transfer box comes up but stays at the 'estimating time' stage and remains like that. No matter how big the file/group of files are (biggest I've tried was only 500-odd MB) it won't transfer and stays at the 'estimating time' stage. When I try and stop the transfer, the transfer box remains at the 'stopping' stage until I restart the iMac. I can access other programs during this 'stopping' stage, as long as it doesn't involve the External HD.
When I attempt to open files from the External HD in Photoshop CS4, both Photoshop and Finder stop responding and have I have to 'Force Quit'. However, upon force quitting finder, I loose all icons on the desktop until I restart the Mac via holding down the 'Power' button on the back.
Ive already done a couple things.
- I excluded the Ext HD on the Spotlight>Privacy tab.
- I verified the Ext HD via System Utilities. Some errors came up but the Repair was successful and subsequent Verifications have returned as 'OK'.
- I tried the Mac Diagnostic tool as suggested by Apple, but when I press the 'D' key on start up nothing happens.
The annoying thing is that this problem came out of the blue, the Ext HD was working fine 3 days ago.
My system:
iMac 21.5inch, mid 2010
3.6GHz Intel Core i5
8GB 1333 MHz DDR3
OS X 10.9.5 (13F34)
The Ext HD:
Western Digital 2TB
Mac OS Extended (Journalised)
1.91TB available on the HD
Shares a 2 Bay ICYBOX dock with another 2TB WD HD
Connected to the iMac via USB 2.0 to a 4-port USB 2.0 hub

I have a MacBook Pro running OSx 10.9.4 and have been successfully using Time Machine with a WD My Passport External Hard Drive for a while. Now (after 10 days with a successful back-up), the computer will not back-up. I have gone into disk utility and tried to erase, partition, and/or repair the disk, but repeatedly get error messages - it can't erase the disk, re-partition the disk or unmount the disk.

MacBook Pro, Retina, 15-inch, Late 2013
OS X Mavericks 10.9.5
USB 3.0 External Hard drive
I am currently using an external drive for my user storage. Right now I log in with a separate User account to mount the drive, log off, and then log in with my user. I am trying to remove the extra steps so I can boot my Mac and log right in. I have not found any method that pertains specifically to Mavericks, and all of the methods I have tried for older OS versions do not seem to work properly.

Rather than empty the trash which now contains all the data on my external drive I ejected the external drive immediately. When I ejected the WD external hard drive the trash bin no longer displayed any trash inside of it, and when I re-connected the external drive the "trash" (contents of my external drive) appears again in the trash. Is there a way to break the connection which has formed between my data on the external drive, and my trash bin? I was simply trying to eject my external drive as I've done hundreds of times by dragging the icon to the trash/eject area. I don't want to risk losing the data. I restored my computer, and upgraded to Mavericks.

A few months ago, I inherited this 2010 iMac and finally getting around to personalizing if for my use after finding a way to get rid of the admin pass. So today, I downloaded Mavericks, the AppStore updates and hooked up my 'WD External HD My Book Essential' and only after loading everything to iTunes did I realize that the HD is read only. I looked a couple of forums and thought I found something but to no avail. I saw a post that suggested the installation of NTFS-3G (I converted years ago to NTFS from FAT32 for space reasons.) However, I still had problems! disconnecting and reconnecting, uninstalling and reinstalling, heck 'macFUSE' keeps coming up as being unsure if it's even installed so I installed 'FUSE for mac' and I keep getting the same message:
Library not loaded: /usr/local/lib/libfuse.2.dylib
Referenced from: /usr/local/bin/ntfs-3g
Reason: image not found
Once I uninstall 'NTFS-3g', my external will show up on the desktop and I can access it.... still as read only but it's there. I have a huge music library and if I can actually have access to it since my old Windows got fried and I now have a iMac as a personal computer. I really don't want to reformat it since I have so much on it and losing anything would be a devastation.
