IMac :: External Hard Drive No Longer Readable

Sep 24, 2010

I have had this WD "my book" ext. HD for about a year without a problem. Today after restarting the computer I got a notice, instead of the HD icon. On screen I got a box that said "the disk you inserted is not readable by this computer" below this was 3 options. Initialize, ignore, eject". I was afraid that initialize would erase or reformat the drive so I pressed eject, I've tried many times but still the same thing. Has my ext. HD died? Should I click initialize? All my backup data & time machine, music,etc., is on this drive, I don't know what to do.

OS X :: External Hard Drive Not Readable By Computer

Feb 8, 2010

I have an external hard drive that I have been using for back ups for several months, but now I get an error message that says, "The disk you inserted was not readable by this computer". I looked up other peoples issues with this, and they have used things like disk warrior to fix it, but I am not very interested in saving what's on the hard drive anyways. I just want to clear out the hard drive and start fresh.

I can't manage to format my Seagate 500GB external HD correctly so it can be readable with my Macbook. I formatted like six times already in Windows 7 and XP to NTFS and still my macbook won't read it...only my Windows computers can read/write it. What am I doing wrong?

MacBook Pro :: FAT Formatted External Hard Drive Is Not Readable By This Computer

Jun 2, 2014

when I insert my 'FAT' formatted external hard drive (Samsung M3) into my mac book pro it comes up with the error message that says "the inserted disk is not readable by this computer" and I therefore cannot access the files. The story (potential further details): 

1. I had a problem with my mac where it took hours to load each time I turned it on, would only work when power was plugged in etc. so I had to reformat my mac hard drive (when I tried to veriify it said repair, that wouldn't work). So i'm starting with a recently reformatted, clean mac. 

2. Before doing this I reformatted my external hard drive (whilst on windows machine) to FAT32 (so I can use on both windows and mac) so that I could back up my files. 

3. I then transferred files from mac onto external hard drive and then also put them on a windows machine. 

4. After reformatting mac hard drive when I then tried to transfer files back onto the mac I get the 'not readable' error. 

Info:
MacBook Pro, iOS 7.1

Dec 8, 2009

I just bought a new 1 TB external hard drive for back up purposes. When i connect it via USB to my Snow Leopard macbook pro, it gives me a "this disk not readable by this computer message". I click ignore, and it lets me do whatever i want to the disk - read, write, etc. I have tried repair disk - tells me it's good to go, and tried reformatting several times - thought not zero disk data or the 7 pass bs.

Mac Pro :: New Hard Drive Not Readable Or Usable

Apr 15, 2008

I installed a hard drive to a new Mac Pro, the physical install went fine. When I booted the computer, it said the drive was not readable or usable or something along that lines so I went to disk utility and erased the hard drive with the Mac OS Extended (Journaled) setting selected. Now the drive seems to work fine but I haven't tested it much. Is everything ok with this drive now? Is Journaled the best setting? Is there a better setting to use for video editing. The drive is: WD Caviar GP 500 GB SATA

OS X :: Best Format For External Drive Readable In OS X And Windows?

Nov 3, 2008

I have an external drive that will need to be connected at different times to both my Mac (Leopard) and my Windows XP & Vista machines. I had it formatted for Mac OS (Journaled) but it wasn't readable in XP or Windows. So what is the best format so that all can read/write to it normally? NTFS? It needs to be able to handle larger files (4GB and bigger).

Mac Pro :: External Backup Drive File System Readable By PC?

Sep 7, 2009

I'm considering using dedicated internal drive for TimeMachine backups and an external drive for an additional backup of photos, videos. Wondering if there is an option for formatting an external drive with a file system that could be read by a PC so that I could transfer images or videos by simply plugging the external drive into the PC.

IMac PPC :: Make Hard Drive Into An External Hard Drive

Mar 1, 2012

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. 

I want to save the hard drive and put it in a case, then use it as an external drive on my other Macs. 

What sort of case do I need to shop for? Should I look for SATA or what exactly is the proper nomenclature. 

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?

MacBook Pro :: External Hard Drive No Longer Appearing-Shows Up As "Vendor-specific Device"

Jun 14, 2012

I'm using a 500GB WD external hard drive to store a lot of data. It's been working fine, plugged into a USB hub. Suddenly, today, the drive stopped appearing when I plugged it in. I've tried plugging it in directly to the computer, it doesn't help. In system profiler, the USB port shows up as : Vendor Specific Device. The ID is confirmed as being from Initio, so I was rather dismayed. Upon trying the drive with another computer, same thing. The drive just shows up as an Initio device, not my external drive. I've rebooted and changed cables many times.

IMac :: Freezes While Using External Hard Drive As Main Drive

Jun 6, 2010

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?

IMac :: External Storage - Ssd Drive - 2TB Hard Drive

Nov 22, 2010

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?

IMac :: Won't Work With External Hard Drive

Mar 11, 2009

which external hard drive (for backup purposes) or empty hard drive enclosure (so I can buy my own drive and install) to get for an iMac, which meets the following criteria:

- has Firewire 800 (or Firewire 800 and USB 2)
- stylish to look at (preferably matches the current iMac)
- has a good quality, reliable hard drive (no cheapo Maxtor drive or whatever)
- preferably is bus-powered (saves yet another wall-wart and power cable)

If it comes with a drive mechanism it should be around 400 to 500 GB.

IMac :: External Hard Drive From Vista On Mac?

May 23, 2009

First let me say I just bought my first mac yesterday and I LOVE it! i am so glad i am finally using a mac!

Now onto the little issue:

I have a 500gb external hard drive with a Music , Anime, Books, and Movies folder. I tried deleting the music folder and I could not, so I used my old vista laptop with the hard drive and deleted it. Then I plugged the hard drive back into the mac, now there is a $recycle.bin folder that i can not get rid of, i can put it in the trash, but can not empty the trash.

I tried downloading NTFS-3G Stable Read/Write Driver, but it does not do anything.

IMac :: Won't Boot Linux From External USB Hard Drive

Nov 14, 2010

I have an Intel iMac with with Snow Leopard and Windows 7 on separate partitions. Recently I have acquired an external USB hard drive. I formatted it with Ext4, and installed Linux Mint to it.

The installation went smoothly, but I can't seem to boot from the USB drive anymore. Holding down Option on start-up only gives me two choices: Mac OS X and Windows. The drive isn't recognized in either operating systems anymore: on Snow Leopard I get "The disk you inserted was not readable by this computer" and on Windows, it doesn't even show up in My Computer.

IMac :: Unable To Transfer From External Hard Drive

Jan 12, 2011

My 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?

IMac :: External Hard Drive & System Sleep

Oct 6, 2009

I'm running out of space on my Mac Mini's disk because of all my iTunes video files. I am thinking about buying an enclosure for my spare 1 TB hard drive, and using it as the location of my iTunes library, but I wondered how it works with the Mac Mini's energy-savings mode. My Mini is set to sleep after 15 minutes of inactivity, then wake when iTunes content is requested by my Apple TV or Airport Express. I like it, because it's very energy efficient that way! My question is, will the disks also sleep along with my computer, and will they wake properly when the computer wakes?

IMac :: How To Transfer Files To External Hard Drive

Oct 15, 2009

I have an IMAC and I am having problems transferring video files I download to my external hard drive. I had trouble playing the files at first because it was not readable with Quicktime. I downloaded VPN and it played with VPN. I don't want to save those files on my computer so I would like to transfer it to my external harddrive. When I try to drag it over, it won't let me drop it in. I am new to the MAC world. Is there a way to choose where it will save itself right before you download like there is on windows. I click on it and it does not prompt you, it just starts downloading.
