IMac :: Hard Disk Makes Read And Write Noise

Oct 25, 2010

I have my iMac since August. I use it a lot, and I've noticed that the hard disk makes read and write noise a lot of times, even using Safari, for example. It looks like fragmented. What can I do?

PowerPC :: Hard To Read / Write To External Drives With G5

Sep 17, 2007

This issue has been killing my work flow for quite awhile. I have a G5 dual 2.0. I can barely read or write files to an external hard drive. Say I try and copy 1.56GB of audio (12 files) from my external drive it will start to copy then stop at 500mb for minutes then start moving as normal and stop again around 900 for minutes.. then again at 1.4. This also happens when writing.

Here is the confusing part. This happens with two external drives (different models) with firewire 400, 800 and USB. I have reinstall OSx. I have repaired permissions and ran repair disc on everything. These hard drives work FLAWLESS with my Macbook Pro as well. Gr what can this be? It takes forever to copy data to or from a drive which is often how I transfer audio between my desktop and laptop. I should soon have Mac Pro money and this crappy G5 can go out the window. I am on 10.4..

MacBook :: Why Can't Read Or Write From My External Hard Drive

Mar 25, 2012

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.

OS X V10.7 Lion :: Read And Write To External Hard Drives?

Apr 13, 2012

hey all, this has been really frustrating for me today. i want to be able to write to an external HDD that's formatted in NTFS. today i find out it isn't possible to write to this file system on a Mac and that on FAT32 it is possible. however, FAT32 can't address files larger than 4GB so this hurts me a lot. are there any other file systems that'll allow me to read and write from a Mac? my goal was to use freeNAS to build a NAS with an old tower and connect my external hard drives to it, but if i can't write to them this may not be possible.

OS X :: External Hard Disk Changed From "Read And Write" To "Read Only"

Aug 12, 2010

I have an external Transcend HD, which has been working perfectly fine for around 5 months now. It is NTFS, and I use NTFS-3g and Macfuse. Been running fine. Was able to read and write. Suddenly I am only able to read though. I go into the "Get Info" pane and the option to choose whether I want to read and write, or read only is gone, and all that it says is "You can read only". getting this back to read and write is really appreciated. I really need this disk.

OS X :: External Hard Drive Folders Unlock To Read & Write?

Nov 14, 2010

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??

OS X Leopard :: Disk Write Cache Corruption On External Hard Disk?

Feb 15, 2011

Recently I purchased an external hard disk, to put all of my pictures of my baby due to space limitations on my internal laptop drive. Since my Canon camera 10 megapixel pictures take up a ton of space this was occurring at an alarming rate. My intention was also to back up to DVD but never got to it. This is both a comment and a question.

Now said baby, is getting really good at pulling cords etc. He managed to do this on the external drive firewire cable. As far as i know the drive was not in the process of actually writing. However, after a few minutes and trying to re-plug the drive the OS crashed with a Grey Screen of Death hardware error that tells you that you need to push the power button..

This apparently corrupted the drive's directory. Upon reboot the drive would not mount. Since there were time machine backups on the drive too Diskwarrior was not able to reconstruct the drive in the built in memory available on the computer. Time machine stores millions of files and Diskwarrior apparently wants to keep it all in memory at once. Since my computer has 2GB you would hope that would be enough but apparently not. So that failed. Other utilities seemed to be able to find the files but not restore the directory. I also took it to the apple store they were not able to recover it.

I have to say this is extremely distressing, and hard to believe that a simple accident like this could cost the loss of thousands of pictures. I did send it to a rescue company but that was expensive but I think apple needs to do something about this situation.

On Windows there is a way to disable the write cache for external drives. This is not available for Mac OS X. This would prevent this rather common occurrence of a plug accidentally becoming disengaged when the drive is not in the process of writing. This reduces the odds but I still think apple, in order to become clearly superior, needs a better solution.

I know Apple has experimented with ZFS would this not eliminate this possibility of this kind of disaster? Is this in Snow Leopard desktop? I know they are thinking this is a business customer focused technology but clearly if it can eliminate this kind of thing then I think it is extremely useful to their non server customers. Perhaps there are other ways of dealing with this issue but ZFS is designed to deal with these issues. HFS+ is extremely fragile to disk corruption.

I know my situation is not that uncommon and this is not the first time this has happened to me with an external drive. You would think I had learned. I hate to think of how many other people have had the same thing happen to them.

OS X :: Unable To Write To External Hard Drive Anymore

Dec 10, 2009

I have a Toshiba 250GB external hard drive to back up pictures. I can write to it just fine. I also have a Fantom Drive 1TB external. I could write to it last week, but I turned it on this week and I can't write to it. I can still pull stuff off of it, but I can't write to it. What can be causing this? I have already installed MacFuse and NTFS-3G. It doesn't make sense to me that I can't write to it all of the sudden.

OS X :: Unable To Read / Write / Eject Shared Network Volume?

Jul 24, 2008

I have my iMac and PC connected to each other through the ethernet. The iMac is set to read/write the shared network volumes on my PC. The Finder is used to set up the SMB connection. Everything works fine. Mac applications are able to read and write files to the PC.

However, after a day or so (during which the PC has been kept on, while the Mac has slept) problems occur. It seems as if it is possible to access the network volumes and even view the root directory. However, clicking on any directory will show a blank directory.

Windows On Mac :: Access Data On Partition - Full Read / Write?

Nov 11, 2009

Been a Mac convert now for about a year and haven't really looked back. So far the only thing keeping me from going straight Mac is Quicken. Hopefully this spring Intuit will get the latest Quicken for Mac right, but I digress. I am currently running VM3 to boot into Windows 7 in order to use Quicken, and a few other things from time to time. But this new Modern Warfare 2 game kinda has me thinking I might need to install Windows 7 via Boot Camp in order to give it a try. With that said, if I install W7 via BC I'm I able to access the data on my Mac partition, and with full read/write access? Furthermore, do I understand correctly that VM will then allow me to access my BC install from within it, thereby having the best of both?

MacBook Pro :: Paragon HFS+ For Windows Can't Read / Write Flash Drives

Apr 10, 2012

I use Paragon HFS+ for Windows which allows me to read and write to my HFS formatted drives. It works great for any external hard drive I use but when I use a flash drive it doesn't work. I format both my external hard drives and flash drives the same way, I use Disk Utility, I format them using Mac Extended Journaled and GUID partition scheme. When plugging in my flashdrive, my Windows 7 PC will not mount them. Disk Manager shows 3 partitions: EFI, Fat32 and some empty space. If I format my flash drives using the Master Boot Record partition scheme they work great.

So, here's what I have so far:†External hard drives work fine when formatted with the GUID Partition scheme. (Mac extended journaled) Hard drives also show 3 partitions in Windows Disk Manager: EFI, HFS and empty spaceFlashdrives show 3 partitions but oddly enough the second partition shows as FAT32. But is completely unusable in Windows 7 Flash drives have to be formatted using the Master Boot Record partition scheme when formatting them as HFS+ volumes in order to work on Windows 7Windows 7 supports GUID partition schemes.

What is causing my Macbook Pro to treat an external hard drive differently then a flash drive when formatting them? Experience and common sense tells me that it shouldn't matter whether it's a flash drive or spindle drive, both should format the same. Granted, I could simply use exFat or FAT32 on my flash drives for cross platform compatibility however I prefer to use HFS+ when possible.

All my old office files have become "read only" and I cann ot modify and save w/o renaming. Is there a "blanket" way to change the Permissions to "read & write" for all my Office files? Idid not see a similar item in the FAQ's......

Also, when I open an Office application, I get the following message: "An unexpected error occurred while trying to load the Microsoft Framework library". How do I fix that?

Software :: Unable To Write To WorldBook NAS / File Could Not Be Written To The Disk

Apr 7, 2009

I am a Mac convert now two years and was beginning to truly believe Macs are impervious to the hair pulling and teeth gnashing so often associated with PC's but...I have been repeatedly trying to write to my WorldBook NAS which has previously worked beautifully but everytime I try to write anything remotely large, I get the message,

"An unexpected error has occurred the file could not be written to the disk. Error Code 51"

My NAS is 2TB and attached to my D-Link wireless. I have used it exclusively for my iTunes library and it has worked very nicely.I experienced this the first time with one of three movies I am adding to my library. After a couple tries, I decided to let iTunes copy it to the folder in it's process of adding it to the library and it worked fine. The following day I repeated the process and now I get the message through iTunes as well.

OS X :: Write On NTFS External Hard Drive - Won't Mount?

May 26, 2010

After a lifetime of owning PC's I finally purchased a MacBook Pro running OS X. I installed Parallels Desktop 5, Windows XP, and several Windows apps to have dual functionality. Now I need to write to my NTFS ext. hard drive where I backup everything. It has 800gb of space left, so it would be a shame to get a new one just b/c I have a Mac now. I first installed MacFuse and then NTFS-3G. Now when I reboot, the ext. HD won't mount at all. What have I done wrong?
