Help! External HDD Problems.

I just used windows to format my Maxtor OneTouch 250GB to NTFS so that I can use with my iMac, however, when I connect the HDD to my iMac, the HDD comes up as a read-only drive.
How do I change that? I've already tried using the "Get Info" option to change it, but I cant change anything from there. What are my other options?

I had recently purchased a WD Premium Edition II drive and had naively thought to use it on both a PC and Mac. After transferring several hundred gigabytes from the PC and attaching to the Mac, I found to my dismay I could not write files. However after visiting Macosxhints page:
http://www.macosxhints.com/article.php?story=20070220150856279
I was emboldened by the March 3, 07 comment by jo7ker and downloaded the current version of Macfuse from google (0.3.0) and the 1.516 version of NTFS-3g (http://shadowofged.blogspot.com/2007/03/ntfs-3g-for-mac-os-x.html). I did not have to fix any errors or run terminal, the NTFS drive showed up as a network drive and I was able to read and write to it from both a Mac and PC. Yea, and kudos to the programmers who made this available.

Yosemite - Win7 on Parallels - Adobe - External HDD - PROBLEMS

Hi
Hope someone can help, have the same problem or even better, have a soluion, i have a macbook pro retina with 2,6GHz intel core i7 and 16 GB ram. When i got the mac i purchased parallels 9 and was then running on Mavericks OS.
Using Adobe CC series on a daily basis i have alot of files so everything is stored on a external HDD, it has all been working super super good, BUT, after upgrading to Parallels 10 and then Yosemite, Adobe programs (its only these programs that has this problem) are running superslow when ever saving, opening, mounting a file etc, sometimes it runs super smooth, but then it can lock up the program for 1-4 mins and then run ok for a short period. Everything is ok but the Adobe program used states as not responding in the activitymonitor.
I know this might be a question for Apple and Parallels forums, and i have asked the same thing there, but really need to sort out what is causing the problem since alot of working time now goes to waiting for the adobe program to respond.
Thanks in advance!

Trying to mount external HDD, problems arise

Been trying to mount my external HD but it's not playing ball. Firstly, I can't work out what my setup is naming it in /dev, partly because I'm getting inconsistent readings of available space on my internal HD.
If I run
df
when the external HD isn't plugged in, I get the following output:
Filesystem 1K-blocks Used Available Use% Mounted on
rootfs 7662396 2662828 4615216 37% /
/dev 1024816 0 1024816 0% /dev
run 1027740 204 1027536 1% /run
/dev/sda3 7662396 2662828 4615216 37% /
shm 1027740 0 1027740 0% /dev/shm
tmpfs 1027740 8 1027732 1% /tmp
/dev/sda1 99590 17903 76468 19% /boot
/dev/sda4 152576072 2634200 142302968 2% /home
I figured that if I plug it in and run the command again, something new should pop up and I can thus figure out what's where. However, the above reading doesn't even make sense.
Firstly, there's sda1, 2 & 3. I only have two partitions on my hard drive (one for /, one for /home). I also have a swap. Yet reading the available spaces, there's four different places (going on size); 1027740, 99590, 152576072 & 7662396.
My internal hard drive is only about 160 gig.
If I open thunar and view the properties for /, I get the following:
Size: 106764 items, totalling 128.0 TB
Free Space: 4.4 GB
From memory, the partition allocation for / was 10 gig, so the free space reading is presumably correct, but the 128 TB reading is bizarre. My external hard drive is 1TB, so it can't be that it's adding together / & the ex. HDD to get that estimate (if it is, it's worse at maths than I am); plus it gives the same estimate regardless of whether or not the ex. HDD is attached to my PC.
If I run:
lsusb
with my external HDD attached, it registers just fine (OK, it gets the size wrong, but it's better than nothing)
Bus 001 Device 004: ID 1058:1021 Western Digital Technologies, Inc. Elements 2TB
Anyone got any ideas about what's going wrong and how I can amend things?
(this is the first time I've had a Arch setup -previously ran Crunchbang- so I acknowledge that I may just have missed something I should have installed/configured)
Insights much appreciated :-)

Ohhh, pmount worked a treat ^ ^
Any way to get it mount it automatically when I log in?
mm..I guess you can put it in your ~/.xinitrc file
but put the line before the DE/WM invocation line.
so, if you use say, use lxde and have a line like
exec ck-launch-session dbus-launch startlxde
in your .xinitrc,
put the 'pmount device' line before that.
Edit. if u want to put it in ~/.bashrc, you'll have to start a bash terminal at least once after you log in to get it mounted.
Hmm, pmount isn't working as well as I thought.
It won't let me transfer files from my hard drive to the external; says it isn't permitted. If I open thunar as root and try to change the groups read/write permissions it says the operation isn't supported (though I myself have read/write access apparently :s).
Edit: Typo
pmount is just a wrapper, it calls the standard mount program to actually do the work, without the need to have an entry in fstab. Let's first make sure that you can mount and use the drive with the standard old-fashioned mount. When we get that to work, switching should be just a matter of using correct pmount options or doing some minor tweaks.
From what you linked, I assume you are using ext filesystem, which should make things a lot easier. If you're using something else, you need to let us know.
First things first, lets start from the beginning. Umount the drive and set permissions on the empty directory you're mounting it into back to root (or just remove it and recreate it as root). This is not essential, just doing that so we know the current state of things.
Second, mount the drive with simple mount /dev/sdx /mnt/mountpoint Obviously you need to change the device and mountpoint to whatever's appropriate. This *should* work. Logged in as root, try to create a directory inside, and for example copy something into this new directory, to make 100% sure that the drive is correctly mounted. If you get past this point and everything works, then this all is most likely just a case of botched permissions. You can't write into it as a user yet, but we now know that it can be correctly mounted.
Third, find out your user uid, and your primary group gid. Simply type 'id' into terminal logged in as regular user you want to mount the drive with, if it's the only user you created shortly after system installation, then most likely your uid will be 1000 and gid of users group will be 100. Now umount the drive, and re-mount it with running as root mount -o uid=1000,gid=100 /dev/sdx /mnt/mountpoint Again, change everything as appropriate. You now should be able to write new files and directories onto your drive as your normal user. You still may not be able to edit files already stored in if permissions were set wrong, but that can be changed, as we discussed before.
If this all works, then you can use your drive without any problems, and one line in your fstab will mean that you can mount the drive as user without even needing pmount. Please verify everything works first, if it does we can help you with that as well if you need it. And sorry if I'm being too thorough, just trying to avoid any mistakes
edit: to avoid any confusion, this is more or less a test. When mounting ext partitions you shouldn't have to set things like uid, gid or umask. Those options are primarily meant for filesystems which don't use this kind of permission setting, like vfat or ntfs. But it should move us a little bit further.

Samsung 1.5TB External HDD problems - very slow and crashes Mac

I recently bought a Samsung 1.5TB Story Station External HDD, to supplement my full iomega 320GB drive (firewire). The Samsung is USB 2.0, and I quickly realised that the Mac only has USB 1 - i.e. very slow. The HDD took about 15mins to even register in Finder and transfers were inevitably slow.
I bought a new USB 2.0 PCI card, with 4 external and 1 internal USB 2.0 connectors. Installed securely and correctly, it should be plug and play right? Wrong. Firstly I checked with a Compact Flash card that the USB 2.0 was working and it is - very fast upload of images to the Mac. Then I tried to move a group of files from the Samsung to the iomega drive and it started off transferring really fast, saying under one minute to perform the task. Then it froze, and slowly worked it's way up to 2hrs remaining. I had to crash out of it in the end. I tried a few simpler transfers, but it froze in finder each time. Now the Samsung drive is not even getting recognised by the Mac.
What am I doing wrong? Is there a shut down/eject order that I have not been doing? I usually just shut down the Mac with the HDDs on, and that has never been an issue for the iomega drive.
Any help or links appreciated. PSD

Hi-
Welcome to Discussions!
External drive controller chipsets vary greatly.
Along with this, and a big problem for PPC Mac users, is that the makers don't take PPC Mac architecture into consideration.
The first mistake is to rely on USB/USB 2.0 for connection.
Firewire is +the surest+ bet for an external drive for a Mac.
USB 2.0 is for WinPC machines, which often don't have firewire.
It is NOT a reliable connection method for hard drives.
Second, these ready made externals are often a problem with PPC Macs.
WD MyBook, Seagate FreeAgents, and others, are often just no good.
I don't see why the Samsung would be different.....
The best way to use an external drive, is to get a firewire drive enclosure kit that has an Oxford chipset, and then install the drive of your choice inside.
http://eshop.macsales.com/item/Other%20World%20Computing/MEFW91UAL1K/
These all have drives installed, but the case and controller is definitely no problem:
http://eshop.macsales.com/shop/firewire/1394/USB/EliteAL/eSATAFW800_FW400USB
I would return the drive.
Is early failure a problem? Look here:

External Hdd problem with macbook pro 13" i5

I bought a extern hdd last week and i have detect that it doesn´t initialize when my early macbook pro 13" i5 come back from sleep or i turn on the mac. I must reconnect the hdd´s usb cable. My question is... Thats it normal?

Very true that if you don't see it in Disk Utility, you also won't see it on the desktop.
It sounds like you have an intermittent contact somewhere. It might be worth trying a different cable and a different port. Also try that cable with some other device.
No idea if the problem is with the drive's port, the Mac's port, or the cable, but you might be able to chase it down by trial and error. It may be something like a cable that is not fully engaged in the port and not making good contact.

10.4.10 external HDD problems

Hello folks,
It was my great misfortune to buy two USB/Firewire enclosures recently, just after updating my OS, only to discover that there is a problem with 10.4.10.
Most posted problem seems to be with some Firewire audio devices . I have seen a few regarding USB external HDD's too but my problem is that my two USB/Firewire drives are not recognized when i connect them via Firewire but work fine with USB. Seems there's absolutely no rhyme nor reason to this bug. I think I'm just going to sit it out and hope Apple get onto this quick sharp. I cringe at some of the lengths some folk are going to, to get back to 10.4.8. just hope there aren't too many folk that make a bigger mess of their systems trying to right this bug.
Having had used Apple Mac's for over 10 years now i have to admit this is the one and only time i have been stung by an Apple software update.... just means I'm going to have to delay my archiving for another day so not that bad all in all.

Seems there's absolutely no rhyme nor reason to this bug.
It seems to me that the problem is limited to certain external FW-connected drives or enclosures. For instance, some LaCie drive models that would not work reliably with 10.4.9 do work perfectly with 10.4.10 while other LaCie models that did with 10.4/9 don't with 10.4.10.
I suspect this has to do with the firmware in the device & the fix involves both Apple & the manufacturer working together to standardize the firmware & how it is accessed by the OS. This is no easy task because various manufacturers use proprietary firmware or custom hardware components & they are not easily made compatible with one another, to say nothing of with both Microsoft's "non-standard standards" & independent standards organizations based ones.

External HDD problems?

I have just purchased a Toshiba STOR.E ALU 2 external HDD to use as a back up drive. When I try to send files to the drive they will not go and an error message pops up saying that the drive is read only.
How do I change the settings to read and write? The instructions only list the device as being Windows compatible but I have a HDD that is 7 years old that works fine with my Mac.
The HDD icon appears on my desktop and I can open it and browse the files that are already on there. If I left click on the HDD then select get info it tells me that the drive is formatted to Windows NT File System (NTFS) however my 7 year old HDD is formatted to MS-DOS (FAT32). Would changing the new HDD to MS-DOS (FAT32) cure my problem and if so how do I go about doing it?
Any other ideas?

Connect the Drive to the Macbook Pro, open Disk Utility and select the HDD at the sidebar, click the tab labeled "Erase". Choose the format (FAT) and click "Erase". This will allow the HDD to work both on Mac and Windows.
Warning: Formatting will cause the data of the drive to be wiped, so any files you want to keep should be temporaly placed on other device (your Mac, the other HDD you have, etc) .

Sudden Time Machine & External HDD Problems -*All Backups gone

I really hope someone can help...
Today, I went to backup my MacBook Pro files using Time Machine and my external HDD, as usual.
Until today, Time Machine and the HDD have been running fine, and today I saw all backups in the HDD going back to September 2011.
However, today when I tried to backup an error message came up saying there was not enough disk space on the HDD. Here's the error message:
>>>
Time Machine could not complete the backup.
This backup is too large for the backup disk. The backup requires 299.79 GB but only 50.95 GB are available.
Time Machine needs work space on the backup disk, in addition to the space required to store backups. Open Time Machine preferences to select a larger backup disk or make the backup smaller by excluding files.
<<<
Nothing would work. So I deleted 1 backup to free some space, but the same error kept coming. I deleted another backup...no go.
Then all of a sudden all HDD in Finder is showing NO backups/files/folders...nothing!!!
Time Machine still thinks all the old backups are on the HDD. So does finder, which shows the following for the HDD:
Capacity: 159.7 GB
Available: 50.95
Used: 108,747,599,872 bytes (108.75 GB on disk)
Yet NO backups/files/folders are showing on the HDD under Finder and Time Machine won't recognise the old back-ups — ie, it says "Oldest Backup - None, Latest Backup - None"
I've tried all sorts of things... including restarting, shutting down, repairing the HDD via Disk Utility etc and the tips here: http://forums.macrumors.com/showthre...t=time+machine
But nothing is helping.
I really don't know what to do next.
(BTW, by chance, i did keep two of the old backups that I copied over today from the external HDD to my internal HDD)
Any suggestions would be appreciated.
Thank you.

1. Although I wouldn't recommend what you are asking to do nor do I know if you can do it with the device you are buying (if it has its own RAID card you may not be able to do anything with it.) However, for a software RAID using Disk Utility you would need to partition each drive before creating any RAIDs. Let's assume you partition each drive into two volumes. Call them A1 and B1 and A2 and B2. Then you can create one RAID using A1 and A2, and a second RAID using B1 and B2. Keep in mind that you cannot access two partitions on a single drive simultaneously, so when trying to access one RAID you will find that you lose any RAID speed benefits when trying to access the other RAID to, say, copy data from one RAID to the other or when trying to copy data to both RAIDs from another source.
2. If a RAID is connected to a FireWire port or to the USB port on the AEBS, then it can be used as a TM backup drive. TM can only have one backup volume on any one computer, but multiple computers can backup to the same TM backup drive or to other backup drives, but it would be more efficient for all the computers to backup to the same TM volume. TM will backup each computer separately into discrete folders on the backup drive.
In my opinion I would recommend having a single 2 TB RAID volume that is connected either to a FireWire port on one of the networked computers (and set up as a shared drive) or connected to the USB port on the AEBS. Each computer can then backup wirelessly to the drive except for the computer to which the drive is connected via FireWire, if that's how you choose to set it up.

Moving iTunes to an external HDD - problems??

My iTunes folder resides on my C Drive and is gradually eating available space - if I copy the whole thing into my external HDD and then set the path to the HDD via Edit>Preferences>Advanced so that the path leads to the Ext HDD rather than the C drive, am I likely to screw everything up?
Alternatively, how does everyone reduce or mitigate the physical space used on their C drives?
Thanks in advance

No, but you won't get the expected results. You will simply have an empty library.
Quit iTunes .
Copy the entire iTunes folder to the external.
Drag the original iTunes folder to the desktop.
Hold Shift while starting iTunes.
Select Choose existing library and go to the iTunes folder you just moved onto the external.
Once you are satisfied it works, you can delete the iTunes folder you put on the desktop (freeing up all the space on your C: drive.
The external must be online and ready BEFORE you start iTunes, else iTunes will revert to the internal drive.
If this happens, simply hold the Shift key to again select the library on the external.

Satellite 2430-101: USB 2.0 External HDD problem

Hallo Everybody,
I have Toshiba satellite 2430-101. I recently bought external 40GB hard disk. When I connected to my toshiba usb hub, it says it exceeds the limit of power suppy and I need to detach the external hard disc. When I read from recent questions, somebody suggested to uncheck the power options to the usb hub, but still it says the same. Are they anybody to help me.
Regards
Sri

Hello Sri
Has the USB hub own power supply? If yes I hope that you have tested it with and without power supply.
Can you use HDD if you connect it directly to the Satellite notebook?

Reformatting WD Elements External HDD problem

I have a problem with my WD Elements 2TB hard drive.
So a little background.
I have a mid-2010 MacBook, 8GB RAM 2.4GHz Core 2 Duo, 250GB HD, OSX Lion 10.7.4.
The hard drive is a 2TB USB external Western Digital Elements formatted to NTFS.
So, I used this disk to backup all my pictures and documents from all of the house computers.
I had the only Mac, and the rest were Windows 7 PCs and one running XP
The NTFS worked seamlessly with my PCs and I had NTFS-3G and MacFuse reading the NTFS on my Mac running Lion with no problems at all. None. I never experienced any problems with the NTFS-3G/MacFuse setup that I read about online.
A few weeks ago, I was putting some documents onto the disk from one of my W7 PCs.
After I believed it to be through copying, I clicked “Remove Hardware Safely” in the bottom right corner by the clock.
I was in a hurry to get out the door, and forgot you had to click the bar icon, then select the device from a list that pops up.
I just clicked once and yanked the USB
Then, I realized it was still transferring another file.
Uh oh.
I didn’t have time to plug it in and see what happened, so I left.
A week later, I needed to transfer a rather large .mov file from my PC to my Mac for editing. I plugged in the Elements, and waited for it to come up. And waited. And waited.
And restarted the PC, and waited.
Nothing.
So I plugged it into my Mac.
No icon appeared on the desktop like normal, but “WD Elements” showed up in Disk Utility. I verified and repaired it, not too worried.
It sat there repairing it for about 15 minutes or so, then it came back with an error saying it could not repair the disk.
This was two weeks ago.
I have now found that the drive is corrupted.
When i plug it in now, it shows up, but it takes a very long time to open files on it, and copy/paste and navigate.
it needs to be reformatted.
but, it has 264.3 GB of files on it, a conglomeration of PC and Mac files.
and my hard drive has 60 GB of free space.
I need to get the files off, reformat, the put them back on.
i cant lose any of these files, some are pictures i have no where else (i know, i know...)
if i make a disk image of the drive with Disk utility how large will the file be? 1TB? 264.3GB? or is there some way i can compress it or something?
and, if I make a disk image of the drive, how will i be able to get the files back on?
Thanks.

Take the drive to a Windows PC and install Data Rescue ($100) and let it work on reading the 1's and 0's of the files themselves, outputing the recovered files to another large external hard drive (formatted exFaT on the PC, not on the Mac and not NTFS!)
This is going to take hours to complete, so buy the software upfront and get it over with.
Once it's finished you can hook up the drive to the Mac and it will read it, no NTFS reading/writing software required.
If the PC your using is a Windows XP machine and there is no exFAT, then install the free exFAT for XP from Microsoft first.
Take a second to learn about drives and formatting, it's not wise to use NTFS software as you see now the problem.

2012 Mac Mini and WD MyBook External HDD Problems

I just bought a 2012 Mac Mini (2.5Ghz i5 version) and I can't get my WD external drive to work with it. I just tested the drive with my mid-2010 MacBook Pro, and it works just fine, pops right up and I can view/edit the files on there. When I move it back to the Mini though, the WD drive turns on and the drive starts to move like its turning on, but nothing shows up on the Mini, either on the desktop, Finder or through the Disk Utility.
Any suggestions? To my knowledge the WD drive I have is USB 2.0/3.0 compatible, and I know that the Mini has all USB 3.0 ports so I'm confused as to why it isn't working.
Thanks in advance.

If you have Disk Utility open when you attach it to the Mini, does it show for an instant in DU?
Is it a Bus powered drive or does it have an A/C PSU?

Problems with creating a Time Machine backup on external HDD

Hello!
I tried to make a new Time Machine backup file on my external harddrive today.
Unfortunately it stopt after about 6 or 7 gb with the popup:
''the backup was not performed because an error occurred while copying files to the backup disk. The problem may be temporary. Try again later to back up. If the problem persists, use Disk Utility to repair your backup disk''
I'm certain that the HDD (Western Digital 1Tb) was correctly formatted (Mac Os Extended (Journaled)). It's the same type as my internal harddrive.
I also have a Time Machine Buddy logfile. Maybe that will help in finding the problem.
Also noticable is that after the backup failure, I can't seem to restore or format the external HDD. Once I connect it to a regular pcc and remove and reinstall the driver, I can use it again.
here is the logfile from the latest backup try:

Can't Read/Write to External HDD-Permissions Problem

I have external Seagate HDD, formatted as FAT32, connected to Airport Extreme Base Station. I am unable to Read/Write to this Drive because Finder says I "Don't have permissions" to do so.
Following are details that may be important:
1. I was able to read/write to this drive under Leopard but lost the right under Snow Leopard, after upgrade to SL.
2. In Airport Utility, I set up (2) accounts for the External HDD, "Dad" with "Read/Write" access and "Mom" with "Read" access only. I have Guest Account privileges set to "Read Only". It has been this way for (2) years.
3. Under "Get Info" in Finder, the only account listed is "everyone" with "read" permission only (this is same as Guest Acount in Airport Utility). I am unable to add new accounts because I get error message "The account name is not valid" even though I am using the account name that I am logged in under.
4. I can change the Permissions on the "everyone" account (in Finder) by changing the permissions on the "Guest Account" in Airport Utility. When I do this, "everyone" in Finder now has "read/write" access but my two accounts, "Dad" and "Mom still don't show up in Finder.
5. I also upgraded internal HDD to 1Tb and used Restore from Time Machine. I hhad problems with the restore and did new install of Snow Leopard.
Any ideas on how to make Finder show the two accounts I have set up in Airport Utility?

My apologies for bumping this but I still don't have a solution...any help would be greatly appreciated!

Error -50 problems on external HDD

I am having intermittent problems backing up to a USB external HDD (via ChronoSync). After a couple of days of successful backups they start failing with error -50. When this happens I am unable to write anything to the HDD. Restarting the computer fixes the problem for a day or so, but then it happens again. I do not think that there are any physical problems with the drive or cable because the drive is partitioned (3 partitions) and another partition is used by SuperDuper to make bootable backups and has not failed.
I see messages like this in Console which may be related:

Any suggestions about how to narrow this down will be appreciated. ChronoSync tech support is getting tired of trying to help me and I suspect that it is a Leopard problem.

Try repairing disk permissions.
Launch Disk Utility. (Applications/Utilities) Select MacintoshHD in the panel on the left, select FirstAid, then click: Repair Disk Permissions. Quit DU when it's finished and reboot.
And check here: What to do if your computer won't recognize a FireWire or USB device
*" ChronoSync tech support is getting tired of trying to help me and I suspect that it is a Leopard problem. "* Since ChronoSync wrote this software. If it's not Leopard compatible then Apple isn't responsible. Might be able to get more support here: http://www.econtechnologies.com/pages/support/support_faq.html
