Mac Pro :: Testing Hard Drive Read / Write Speeds

Oct 13, 2010

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.

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 :: 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??

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..

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.

Mac Pro :: Boot Drive - Read And Write Speed Differences?

Apr 27, 2012

My Mac Pro came with a 500GB boot drive when I ordered it 3 years ago.  It has been used most days and now runs Snow Leopard (for scanners and a canopus video box that don't work with Lion) and Lion. I did a write & write test on the drive recently at both were approx 60 - 65 MB/s.  I have another drive in my machine I bought last month, replacing an WD drive that failed in less than 18 months. This new drive (complete same as replacement is a WD Caviar (Black) 1TB 64Mb drive. This drive tests at speeds for 110MB/s.  This may seem an obvious question, but will I notice much difference if I swap the drives around and have the newer drive as my boot drive. Also, does having two OS on a HD slow the drive down also?

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.

Intel Mac :: "Excessive" Write And Rewrite To Hard Drive?

Mar 26, 2012

It's a 27 inch iMac, 10.6.8, 3.06 GHz Intel Core 2 Duo, 3GB 1067 MHz DDR3, late 2009. Recently (last couple of months) I've noticed it seems to be 'constantly' making the write/rewrite noise and is busy doing something. When this happens, activity is slightly stalled, slowed, paused while it finishes whatever it's doing. I check the Activity Monitor expecting to see high CPU but there is nothing especially hogging CPU. But on the advice of another person answering someone else's similar complaint, checked Disk Activity, which does show sharp peaks. I have cloned the hard drive and cloned it back and the problem persists.

Nov 5, 2006

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.

Hardware :: What Format Write / Read And PC Read?

Jun 16, 2009

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?

Mac Pro :: Can't Write To Non OS Hard Drive

May 11, 2010

Starting today, when I try and write anything to my non-OS harddrive (with my music library and data on it), OSX gives me the error: "The data can't be read or written" The permissions seem to be fine. I can open files on the HD fine, but they open a little slow. So basically I only can't write to the drive. What's going on? Is my HD dying?

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 :: 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?

Software :: Error 36 Can't Copy Or Write To Hard Drive

May 5, 2008

The one response I had was: 'alex try putting your mac os cd in and restart the system holding down the letter d key and let me know what happens.' unfortunately I can't find my system disc... will I need to buy a new one? here's a the problem: I have a PPC G5 iMac 2.1GHz, 1.5GB. The Internal Hard drive is 250GB in total and partitioned into 4 sections. After working fine for ages I suddenly found I can't copy files into one of the partitions. Initially I got an error message saying: "DS_store could not be tead or written. (Error code 36)" I used Disk Utility to clean up the hard drive. Which didn't help. Got a copy of Disk Warrior(4.1) to try a more effective clean up. There were a few errors that found and fixed, but i still got the same error message. Then found a utility called DS_Store Cleaner to try and force it to remake the DS_Store files. This got rd of the DS_Store message but I'm still left with another error 36 message and still unable to properly copy. The message then said: "The Finder cannot complete the operation because some data in "example file.doc" could not be read or written. (Error code -36).

I have also got hold of a copy of techtool pro (4.6.1) and run everything - basic, intermediate and advance scans. Everything (aside from a few minor errors on other partitions - which it cleared up easily) was fine, that partition showed no errors at all. I didn't do the full tests on the system partition though as I haven't used the e-drive function yet. The problem has been ongoing since late March.Just today I found the same problem in another of my partitions: "The Finder cannot complete the operation because some data in "example file.doc" could not be read or written. (Error code -36).This happens when trying to copy to either of those partitions or trying to save anything to either of them.What might be causing this and what should I do next? with the first partition to have problems I am unable to copy/write any file size (eg KB size files) with the most recent partition I found I could copy a 2.3MB Jpeg. The problem occured when I tried to copy a 680MB .mov file (there was enough space - about 1.8GB)

MacBook Pro :: Internal Hard Drive - Reading Ok But Cannot Write

Mar 12, 2012

I have a late 2009 MacBook pro, running the latest version of Lion. Last week, I experienced a Kernel panic at start up, and was unable to launch the OS, even with the recovery boot. Starting in verbose told me that there was a sata issue. I opened the computer, replaced the internal hard drive with lion set upon it, and tried to start again, without any success. I bought a SATA-USB cable to plug my old hard drive. My computer is now running normally, but with the former internal hard drive plugged in USB.

Disk manager sees the new one and I can read data written upon it, but I can't write anything nor erase or partition it. So both the hard drives are OK (I tested them in a friend's MacBook pro and it worked), the computer seems OK too, because I'm running it presently, but any internal hard drive won't work. The cable that links the hard drive to the motherboard does not seem to be damaged, however, the status indicator light is not working since that time.

MacBook Pro, Mac OS X (10.7.3)
