View 6 RepliesWithout warning my iMac [OS X Snow Leopard] popped up an alert saying that I should eject a drive before disconnecting it. I had done nothing to generate this error message. I clicked ok to close it and noticed my 4 month old, external 8T Mercury Elite-AL Pro Qx2 was no longer visible in my drive directory. I also noticed this external unit was making a looped grinding noise as if it was trying to write without success. I figured one of the drives failed and took it to the mac doctor. Other than a few directory errors, everything appeared to be fine, so I paid the service fee, brought it home and plugged it in only to find the same prob - obviously it's something with my iMac. Before I go spending more service fees, I wondered if anyone here could point me toward a method of discovering what might be wrong. I ran disk utility [verify and permissions] and fixed some directory errors, but don't know how to look further. iMac was home networked with a PC [Windows] and a laptop [Windows]. I did notice something wacky with the PC, but its very old and I expect it to die any day. I was running the network through the PC, so I direct connected the iMac to the router and modem but no change: still cannot see the external drives. What other info do you need to make an educated guess for me?
View 1 Replies View RelatedMy new iMac is arriving tomorrow and I need to transfer everything over to it. I know about Migration Assistant, but I want to know if there will be any complications due to the data I have on an external hard drive.
Specifically, I currently have an older (white) iMac hooked up to two 2TB external hard drives. One if for backup but the other one has all my iPhoto and iTunes content on it, including about 1.5 TB of movies and TV shows that I have ripped. None of this material is on the computer's internal hard drive - it is all on the external hard drive.
Because my new iMac has a 2 TB internal hard drive, I want to transfer all the iPhoto and iTunes content currently on the external hard drives onto the internal hard drive of the new iMac. Will Migration Assistant handle this and will it be clear what I need to do?
I was wondering how much external memory an iMac G3 1999 will accept! And I'm looking for an external Hard Drive that uses the built in Firewire 400.
btw: it's blueberry. and 400MHz with 512MB SDRam
I have a macbook and I am connecting an external hard drive via USB 2.0.
When I want to delete a folder it gives me "error 1407". There is nothing in the folder and it is not protected in any way. It was a folder created by me only a month or so ago. ALL of the folders on my external hard drive are like this. No files are effected with this issue.
Supposedly, the external is in use and cannot be ejected, but i don't think it's in use. I've only recently been encountering this problem, and i have no idea why. I've tried quitting every application, but it still claims to be in use.

Now, I decided to transfer some of my stuffs from my MBP to this Lacie External, however, it won't allow me. It keeps giving me warning that "Lacie External Hard Drive Cannot be modified".
I had tried to modify the "Lock" property from "Get Info" but its option is grayed out.. I am unable to change it..
I have OSX leopard as a disc image on my desktop. When I try to copy the .dmg file over to my external hard drive it copies for a while, then an error message says it can't copy it over and stops. I'm really confused as this sort of problem doesn't usually happen.
I'm running Tiger 10.4.11 and I want to install Leopard. The Leopard disc image is 6.66GB.
I can't burn it to a DVD either because the discs I have are 4.7GB & the .dmg is 6.66GB. Do I need to buy a bigger DVD blank disc?
Another question is how I should burn the disc. Should I simply burn the .dmg file straight onto a DVD (if I can get one that is big enough!) using Disc Utility?
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.

in disk utility i have tried repairing disk and i get the message "invalid node structure". it then tells me it cannot be repaired and i need to re-format my hard drive.
as i said there is literally YEARS of info on this drive that i really really dont want to lose, is there anything i can do, or anything worth trying. as a side note on the front of the drive it has a capacity gauge and has gone from 3/4's full to not showing anything.
I'm using a 1.42ghz Macmini running 10.4.11. I've been using a Lacie 500 G firewire external hard drive for over a year to store and retrieve files. I have several movies in the mp4 format stored on the Lacie external hard drive. I recently opened one of the movies in full screen (quicktime). It ran for about 10 minutes before freezing up. I watched the spinning beach ball for about 5 minutes. Unable to force quit Quicktime, I pulled the plug on the Macmini. After restarting the computer, the icon for the Lacie external hard drive no longer appeared on the desktop.
I tried several different things to get the icon back, including: repairing the permissions and shutting down the external drive and unplugging the power supply for several minutes before reconnecting the external drive to the computer. The external drive doesn't show up in either the System Profiler or Disk Utilities.
Two years ago I installed Leopard on a pair of striped Fantom Hard Drives (3TBs) via Firewire 800, and have been running my 2007 Macbook Pro off it ever since. When Snow Leopard came out, I updated it with no problems. When Lion came out, again no problems. Last month I bought a CalDigit VR2 with dual hard drives (4TBs) specifically built for running OS externally. But no matter how I configure, install, or connect... it will not boot up my Macbook Pro, or my Macbook Air.
Last week I bought a new Fantom external hard drive (1.5TBs) and discovered the same exact issue, with one exception... the Fantom will boot the Macbook Pro via USB 2.0, but only when plugged into the left side port.
Has anyone else noticed this change?
P.S. I've talked to the people at CalDigit, Fantom, and Apple, and no one seems to have an answer.

I bought a WD My Book Essential to do Time Machine backups. It is formatted for a PC but I was told I need to format for my IMac before I can use it. How do I do that? Is it a complicated process? I have only been using a Mac for about a year now and am still learning about them.
View 3 Replies View RelatedI have 100gigs of music so I successfully transferred my iTunes media to an external hard drive, and identified this new location within iTunes/Preferences/Advanced/Location. Everything worked great until I had to shut down and start up.
Now, it no longer recognizes the media library. When I try to play a track in iTunes, iTunes says the original file could not be found. It prompts me to locate this one track, which I do, and that one track will play. All of the other tracks have the (!) sign next to them in my iTunes library.
I have double checked the settings in my iTunes preferences, everything appears to be configured as when I first made the successful transfer (identifying the external hard drive as the location).
I've made sure to restart once the external hard drive is connected.
One of my important external hard drives recently died and I was wondering of there was a way to see a list of files that were on the drive before it crashed, maybe the spotlight index?
Before sending the drive in for recovery (and not attempting to change the logic board myself) I would like to see if there is any private data on the drive that I wouldn't want to fall into the wrong hands.
i have just bought and external hard drive and want to put stuff on it. i know i hav to format it somehow using disk utility on my imac. what do i format it to so i can use it on both mac and pc? it is set to read only in "get info" and ms-dos fat in disk utility.
View 6 Replies View RelatedYesterday I reformatted my Macintosh hard drive, partitioned it, installed Snow Leopard on one partition and Windows 7 on the other. I installed all the drivers for Windows 7 from the Snow Leopard disc.
When I plug in my 1TB Seagate external hardrive it's not showing up in Snow Leopard or Windows 7. Not even in Disk Utility. I tried plugging the external drive into my Windows laptop and a pop-up comes up saying "USB Device Not Recognised. One of the USB devices attached to this computer has malfunctioned, and Windows does not recognise it." I think that this may just be because it's formatted to Mac OSX?
The hardrive had all of my photos, videos and music on so I hope it's salvageable. I find it hard to believe that the hard drive malfunctioned at the same time I reinstalled the software onto the iMac.
I have looked at a ton of posts on this site and others and find similar problems but cant figure out what is wrong. If someone could point me in the right direction that would be great. I have an Imac 2.4ghz intel core 2 duo 3 gigs of ram. I have an Iphoto library that is 190gigs . I have been trying to transfer the library to an external 1 tb hard drive so I can get my computer to run normal again. When I try and transfer the Iphoto library to the external I get a really lame error code. The transfer will start perfect it will get to about 142 gigs complete then the message :"the finder cannot complete the operation because some data in "iphoto library" could not be read or written. (error code -36). I have looked up the error code and it seems to be one of those codes that doesn't really tell you anything. At first I thought it was a problem with the external, maybe it was not formatted correctly. Then I tried with an alternate drive I had and the same thing. Just to make sure I took back the original drive. Re formatted the drive only one partition, and mac os extended journaled using GUID partition as suggested by many posts. So I don't believe it is the drive at all I can transfer other files no problem. I have not tried to transfer something as large, but everything else, photos, movies, ect seem to be no problem at all. I really do think now there is something wrong with the library but I don't know what to do. I would love to try and make a copy on the computer itself, but there is not enough room. I think I may need to rebuild the Iphoto library but do not want to lose everything.
View 6 Replies View RelatedI am having problems ejecting the external hard drive that I use to back up my laptop. It is a 2012 MacBook Pro running Mountain Lion OSX 10.8.5. My external hard drive is a WD 2 TB My Book Studio. I use it to back up my laptop with Time Machine. Every time I try to eject my disk now I am told that "The disk (Diskname) wasn't ejected because one or more programs may be using it." I have tried some solutions like to stop Spotlight from indexing the disk and to try and turn off TimeMachine, but neither of these worked. The only thing that has worked so far is to log out of my user name and log back in with a guest user and eject it from there. This takes up a lot of time and is ultimately not really a sustainable way of working on my computer.

I have a G5 Imac and a G4 ibook. i want to use time machine, and have one external hard drive connect to both. I could get an external with more than one input (ie, usb and firewire)--does that work? Could i use a usb hub to connect the 2 computers to the HD, and set up different partitions?
And what of NAS? i do not want to set up a whole network (we already have one at my office, and i want this to be independent).
I've got my iTunes Library on an external drive, but for some reason all of my Apps download onto my internal hard-drive, and if I move them onto the external drive they all corrupt.Any suggestions? The music/videos work perfectly.

I received an Acomdata 2Tb external hard drive today from Amazon and plugged it in. Time Machine popped up and I declined to link the hard drive to it. I went into Disk Utility and chose the new hard drive on the left column and went to erase. I chose Mac OS Extended. I named it and hit erase. It started going, and going..... and going... and a half an hour later I knew something was wrong.
Disk Utility was not responding and I eventually had to Force Quit. Now I cannot format the hard drive. I starts and then it stops with a disk error. I tried to run the First Aid verify and repair and both stopped after a few seconds with an error. What do I do?
I am unable to transfer movies from my External Hard drive to the MacBook. The error code is 36. how to get this sorted out?

I've bought a Seagate External Hard Drive, and want to copy my photos from the Macbook Pro to it. Every time I try and copy them, a message appears 'Unable to render file for export' followed by the drive details and a string of numbers. How I should be copying them? I've already accidentally deleted and appear to have permanently lost photos from iCloud, which is why I want a spare copy on an external drive.

Today I went to plug in my Lacie 250 GB USB external hard drive into my 13 in. MacBook to get a shirt template for a design I am making. I discovered that the hard drive just would not mount and show on the desktop, and I remembered that this happened a few days before, but all I did was unplug it and plug it back in, and it worked... except that today, that didn't work at all. I tried the other USB port, and the hard drive showed up on the desktop for about a second, and then disappeared. I kept on replugging it back into both USB ports, but nothing happened.
Then I tried to see if it would work on the PC beside me, and it was recognized as an external device; however, a message came up telling me the drive was malfunctioning. I am guessing this is from ejecting it incorrectly (because I am in a hurry to head to my next classes...I use this laptop at school), but I have incorrectly disconnected it before in the past and this problem never happened to me before.
Every single project I have ever created for my design career is on that hard drive, and all I want now is to get my files back. All I need it to do is show up on the desktop for just the right amount of time for me to copy my files onto my computer.
I read online to put it into the freezer for a while and it should mount, but that didn't work. I tried using Disk Warrior, Data Rescue 3, and Tech Tool Deluxe, but the hard drive did not show up on any of those apps.I tried plugging the hard drive into an iMac as well, but it did not show up either.
I am trying to copy my iTunes folder from one external hard drive to another external hard drive but I keep getting an error message "unable to copy because file (song name) is in use". It starts copying for a while but keeps stopping when the error message pops up. No songs are playing so I am not sure why it says certain song files are in use.

My PowerBook G4 (Alum) died. I've had it for 4 years, taken it with me to Alaska and all over the lower 48, and have had nothing but happy experiences. I knew she was gonna go, but I was hoping she'd hold on until I could afford a MacBook. Alas, no. The problem appears to be the ability of the logic board to communicate with the hard drive. I can hear the HD spin, but even with Disk Warrior, I cannot locate it. The Mac Geniuses at my local Apple store confirmed this and gave me a shoulder to cry on. I've run Disk Warrior, Disk Utility, and tried finding it using the target disk mode - no luck.
The problem is that I've got 4 years of teaching materials, 6000 songs, and irreplaceable pictures on the HD, so I can't bring myself to just trash it. It's true that you only fail to back up you stuff once. This is my once. I've heard that with PC hard drives, you can just drop the old HD into a USB HD box and use it as an external HD. I can't afford professional data retrevial, and I want to give this option a try if it'll work with a Mac HD. Any ideas or suggestions?
I know this is going to be an incredibly easy fix, but I can't find it. The Hard Drive on my new iMac is not appearing on my desktop, nor is it appearing in the "Device" menu in Finder.
if i delete files off my internal hard drive (Macintosh HD), will it still be on my external hard drive or will it just add to it?
