OS X :: Accidentally Unplugged External Hard Drive While In Use?
Aug 4, 2008
today, while i had the external hard drive in my macbook, i accidentally unplugged my external hard drive (the only file i had open from the external was a movie), and it was copying nothing at the time. i am wondering if this little error will cause data damage to the hard drive (this is the first or second time in the year plus i had it that i did not properly eject the hard drive) or do i have to do it over and over again for data damage to happen. i'm concerned because i think a file got wiped (but then again, that file had a bunch of problems reading before the power shutoff today and likely wouldn't have played anyway). should i be concerned about any data damage to my computer or am i fine?

I went to make a copy of an important drive and accidentally re-formatted it (re-formatted mac journaled, originally mac journaled). The drive contained a bunch of important disk image files which I need to retrieve whole. I'm fairly confident that the files are still there and only the table information got overwritten, as the re-format took about 30 seconds. None of the recovery software I've seen however, can retrieve .dmg files, or such large files (these are up to 32 gb each in size).how I can retrieve these disk image files?Â

One night when I was overly tired, I accidentally placed my second hard drive in the trash and emptied the trash in my old G4 Sawtooth (ignored warnings, etc.). This machine is not backed up because I only use it for practice. I don't need to retrieve the data on the hard drive, but I would like to re-format it and use SuperDuper to copy the start-up disk to what would now be a new second hard drive. I can't see the "lost" hard drive. Can anyone tell me what I need to do to locate the second hard drive to make it appear in "About this Mac" and on the desktop ? Do I need to physically remove it and re-install it in the case?

I was installing windows XP to my macbook pro and accidentally formated the hard drive to a FAT32, now when I go to start-up the computer all I get is the grey screen. I have tried holding the "C" key when booting with OS/X disc but nothing happens.

with cloning/copying the content one an external hard drive onto a new external hard drive. Basically, I have a 500GB FW400 drive which I use to store my media files. It's full, so I purchased a 1TB FW800 drive to replace it. Obviously, I thought I could simply copy and paste the media files from the old drive to the new one.I cannot copy the media files to my internal drive first as my internal drive is only 250GB and nearly full itself.I have used Disk Utility to attempt to close the old drive to the new drive, but keep getting "insufficient space" errors.

Recently I bought 2 identical WD Scorpio Blue 1TB hard drives for my macbook pro 13 inch 2010. My aim is to replace the internal hard drive with one of the two I just purchased and use it as my system drive with Lion, Windows and Data partitions. And for the other hard drive I want to use it as a full disk back up for the internal drive (now 1TB hard drive). After I was done with setting up both windows and mac and data transfer, when I booedt into the recovery partition from the internal drive to clone the drive to the external drive, the disk utility gave me this error (Could not validate source - error 254). I also tried using Carbon Copy Cloner but it only could clone partitions, not the entire drive. Yesterday I downloaded a copy of Clonezilla. It worked fine until it had to clone an exFAT partition (my data partition). The exFAT partition appeared as 'RAW' partition in clonezilla. As a result, the whole partition appeared to be full and clonezilla had to copy every single blocks of data in that partition and the estimated time remaining was about 30 hours. So clonezilla is out too. Just want to ask if there is any program/application (bootable or not) which allows can do a full disk clone to an external hard drive.

I purchased my mybook 500gb external hard drive the same day I bought my mac. One day I accidentally unplugged it. Now when I plug it in into the usb hub, it won't pop up mybook icon on my screen. How do I get it to work again?

I've had a lot of problems with my iMac G5 power supply and since I have newer computers I've decided to get rid of this computer.Â
I want to save the hard drive and put it in a case, then use it as an external drive on my other Macs.Â
What sort of case do I need to shop for? Should I look for SATA or what exactly is the proper nomenclature.Â
Is USB 2 the preferred choice, or Firewire, or what? Is there a USB 3? I use a mid-2010 27 inch iMac with the intel processor, and I needed to buy an adapter to use my older Firewire external drive. Is Firewire a dodo?Â

Looking for opinions or comparisons on performance between an internal mac hard drive vs an external firewire 800 hard drive or better. Is the performance on an internal MP drive or iMac internal drive much faster than connecting to a firewire 800 drive? I'm sure it depends on the drive, I'm wondering about apple factory installed internal drive vs say a WD external firewire 800

In other words... I have moved my music library to the external hard drive, as per an earlier thread I read here on the forums. It worked like quite well. Now that it is working perfectly, I am having a hard time leaving well enough alone. It is never a good idea for me to think too much...Can itunes be installed and run on/from an external hard drive? If so, how?

I have an elderly Q950 with an external hard drive with everything backed up onto it. The external drive is a Micronet ADV1000E, with a sticker on the back saying it's Macintosh or PC compatible. I also have an iBook laptop, & PC Dell Inspiron 1300 laptop. As I have the 2 laptops, the Quadra hadn't been switched on for maybe one year. On the weekend I tried to get it to boot up (with & without the external drive switched on), but all it does is display a grey screen with an image of a 3.5" disk with a '?' in the middle. If I start up from a Norton 3.5" disk it still can't find the external or internal drive. If I try booting up with my finger in the shift key it doesn't want to know.
1. Any idea why the Quadra isn't seeing either the external or internal drive & what can I try to do?
2. Is there any way I can connect my external drive to either my iBook or Dell? At the moment I have no cables to connect the old & new - are cables available & if so any idea where from? I've looked high & low but so far no joy.
3. Is it possible to remove the hard drive from the Quadra or the external drive & put in an external drive enclosure, then connect that to either laptop? I see there are drive enclosures available which are Mac & pc compatible. This by the way would be a major undertaking for me. I'm by no means a computer dunce but would be wary of trying it.

when I went into the "get info" window for the G-Drive and switched the ownership/permissions dropdown from "read/write" to "no access". When I tried to switch it back to read/write, it would say read/write in the dropdown, but then I'd try to access the g-drive and I'd only get to the first set of folders--when I'd click on a folder, there would appear to be nothing in it. (Not sure if this is really related to my current problem.)
I then tried ejecting and remounting the drive, but it didn't show up on my desktop. Stupidly, I assumed my computer didn't recognize it at all and unplugged the firewire without ejecting thru disk utility. When I did this I got the device removal error.
I then plugged the firewire back in and tried repairing the disk in disk utility, but it said it didn't need repair. When I click on the G-Drive in disk utility the info at the bottom says:
Mount Point :/Volumes/G-DRIVECapacity :465.6 GB (499,973,603,328 Bytes)
Format :Mac OS ExtendedAvailable :
Owners Enabled :NoUsed :
Number of Folders :0Number of Files :0
0 Files! I'm worried about losing all my stuff! I then tried DiskWarrior (v4.0). When I first opened it I think the info at the bottom said "This disk is a Mac OS Extended disk. This disk does NOT appear on the desktop." I'm not quite sure about that "not" b/c after rebuilding the directory of the G-DRIVE I know it now says "This disk does appear on the desktop." Anyway, it's definitely not appearing on my desktop. After building the directory it said "All file and folder data was easily located. Comparison of the original and replacement directories indicate that there will be changes to the number, the contents and/or the attributes of the files and folders." And later: "19 files (and 2 folders) had a directory entry w/ an incorrect text encoding value that was repaired." And:
Disk Info:
Files: 51,646
Folders: 18, 493
Free Space: 65.42GB
(etc)
I then clicked "Replace" whereupon it said it was successfully replace. But still it did not appear on the desktop even after ejecting, remounting, rebooting computer, etc.
If anyone has any advice I'd really appreciate it. I'm pretty desperate here! Thanks!
(FYI I already tried going into the Finder permissions and unclicking and reclicking the box for showing disks on the desktop. Also, I plan on getting DataRescueII in case that's necessary, but i hope it isn't)

So, I've been searching the forums, as I just had a 1TB (well actually a dual 500GB) external drive stop mounting and start clicking on me. I'm trying to find a way to recover files, and I know I've seen a lot of posts on DriveSavers, which. I was searching around, and I was wondering if anyone has ever heard of a company called "OneWorld Data Recovery." It was something I stumbled across, but I can't find any reviews, or nail down anybody who's used it.
Clearly, this seems fairly suspect, but I figured I'd check and see if anybody had ever heard of it or used it. Thanks!

My internal 1TB hard drive on my iMac is dead and I don't have the money to replace it at the moment. I have everything backed up on an external 1TB drive using Time Machine. As a workaround for the time being,Is there any way I can install the system on the external drive and use that as the boot drive without erasing the Time Machine Backups? It seems to me I would have to have two partitions for the external drive, one for the system, and one for Time Machine. But is there any way to add a partition without erasing the existing one with Time Machine only on it? Â

Basically I have a 750GB hard drive in my Macbook Pro and over 300GB is taken up with 'BackUp' data. This is more than the total of everything I have on the drive other than that. Time Machine has always been setup on an external drive and when searching all files on the Macbook there is nothing for backup files so don't know where it is coming from.

MacBook Pro, OS X Mavericks (10.9.4)

I want to put my old 15" PowerBook hard drive into an external case. I pulled the hard drive out of the PowerBook. And I purchased a NexStar CS 2.5" SATA to USB 2.0 external case. But the connections don't match. What do I need to do? Do I need to buy some sort of adaptor? Hard drive is a Hitachi 120GB 5400RPM (model # HTS541612J9AT00) 2.5" Sorry, these photos are blurry as hell. Picture of hard drive pins:
Pins are in the following configuration (1's represent pins):...............

Lately I've been using my external hard drive as the main drive of my imac I5 and every day it freezes when I open 3 or 4 apps or more or while doing several stuff at the same time. This, obviously, doesnt happen when using the internal hard drive of the imac, so I suppose is due to using firewire 800 or usb 2.0. Is it normal for every external hard drive to freeze when using it as the main drive or maybe is it that my external hard drive is bad?
I'm planning on buying a more quieter external hard drive to use as the main drive of my imac, but I wont do so if it also keeps freezing every day. Any suggestions? Is it normal even when using firewire 800? When using the external hard drive I umount the internal drive of the imac. Maybe this is the reason? Its a Lacie Big Disk 500GB. Would an external SSD make a difference or would it still freeze?

So around 5 years ago i got the WD-160JB hard disk drive. I want to see all the things i did back then. I want to be able to connect this WD-160JB drive as a external hard drive to my mac.Â
What i am wondering is if you can somehow have a cable or something which links the USB from the MBP to the hard disk.Â

I'm curious what people use for external storage on their iMacs. I have a Mac Pro which is getting a little long in the tooth. I'm debating whether to get a new Mac Pro or to get an iMac, which would be a pretty good speed bump from my Mac Pro 1,1. I'd get the ssd drive, and the 2TB harddrive and get aftermarket RAM. But what I like about the Mac Pro is the upgrades you can do. And I like the four hard drive bays, for storage and backup. I've got over 3 TB of photos and music/tv/movies, so I'm going to need an external drive. In addition, I'd like to be able to backup everything. Is there an elegant way to do this on an iMac with an external drive that isn't super loud and hot?
