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..

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.Â

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.

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??

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.

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.

I may end up getting another external hard drive & would like to be able to stay with NTFS so I can use it with either PCs or macs, there is a PC in my home & I would like to be able to use it between the PC & my macbook pro. Does anybody know of good reliable software that does not hog resources that will enable me to read & write NTFS on my macbook pro?

What is the standard tool to test your hard drives read/write speeds? I'd like to test my new SSD to see how fast it really is. I've heard you cant trust XBench for that which is the only thing I have to use.

I've always wondered this: I know when you mount a drive (USB stick, FireWire external or even an iPod of some sort) in OS X, a few invisible files get created. And if you have an AV program, sometimes it will write files to the drive. Same with some other third party apps. Do any of these files contain personal information, or things unique to the machine? Like user name or directory structure or things of that nature? I assume they don't, or else you'd probably see it mentioned more often, but I was wondering if anyone had a definitive answer..?

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?

I have an early 2009 macbook, with 320 GB hard drive and running OS Lion, after i upgraded my os to lion, the computer ran perfectly normal, although a little bit slower than running snow Leopard. However, recently I notice my mac become very slow, got rainbow wheel even when i open the safari. then I use the black magic to test the hard disk speed, it appears the read and write speed is only a little over 30mb/s.
i have recently change my keyboard at apple store, I notice my mac slow down after that, do you think it would related?

Every time I reboot my computer my external drives are all set to "read only". I have to eject them, and remount them and things are then fine again, but this is an annoying step and the fact that a reboot is causing them to switch to read-only is having me worried.
Anyone else have this problem/know of a solution?
I've been trying to figure it out over at the official apple forums but we're not getting anywhere... the thread is here:

i used to have a bunch of files on my hard drive before i sold my mac pro
i backed everything up on an external hard drive so i can keep it until i received my imac. now i have my imac, and when i try to transfer over the files to my imac, or another external hard drive, sometimes the copying stops and says something along the lines of "you do not have permission to copy this file"
so i guess some of my files got messed up, putting them in "Read only" mode.
i know i can go to "Get info" and then manually change it to "read and write" mode but honestly theres so many files it would take a lot of time.
is there a script, or an app i can run that could scan my whole external hard drive so it will go thru each file in their own specific folder and change the permissions to "read all write all" without me doing it manually one by one?

sorry if this is a noob question, but when I try to save things to my new external hard drive a box comes up telling me that the disk is write-protected. Is there a way I can write-enable it? I have tried a bit of searching on Google, but to no avail.

I know this is lame, but I searched and can't find a solution. When I click on a day in ical it says it is a Read-only calendar. I repaired permissions, but it still says read only. The strange part is, in the Get Info screen, it says Read-Write for all the users.

I'm buying an external hard drive to use as a backup for my MacBook but also as a network drive that all the computers connected to my router (Airport Extreme) can use. There are two MacBooks and two PCs that connect to the network. I only need my MacBook to be able to write to the hard drive but I need the two PCs to be able to access and use the files on the hard drive. I was going to get a 1TB external and give it two partitions. The first partition is going to be the Time Machine backup for my MacBook and the other will be accessed by all computers on the network. What format will the second partition need to be so that both MacBooks and both PCs can view and use the files? Also what external hard drive would you recommend?

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.

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?

I have a Late 09 15" MBP and a WD 1TB external HD. I've never had a problem until now. I start up the hard drive, then it loads up fine and the Mac recognizes it just fine. As soon as I try to copy something - doesn't matter how big it is - I get an error and at the end it says "(Error code - 36)". It just says the file cannot be read or written. Weird thing is I can access everything on the hard drive. Anyone have any tips before I try reformatting the HD?
