Hardware :: External Hard Drive Not Working?

Nov 4, 2010

I took 2 storage HDs out of my Mac Pro and stuck them in this external HD which I just bought.when I plug it in to my Macbook Pro and turn it on, nothing happens. It all lights up and the harddrives churn for a little bit, but nothing shows up on the desktop or in Disk Utility. What am I doing wrong? I have tried FW400, FW800, and USB2.0. I'm new to external enclosures, so tell me if there is some song and dance routine I need to perform to get it to show up.

MacBook Pro :: WD External Hard Drive Not Working?

Aug 6, 2010

My MacBook Pro is fairly new, but I have a 500g Western Digital external hard drive that was originally hooked up to my previous computer, a PC. When I plugged in my external, I was able to move files from it to my Mac. However, I was unable to delete files off of the external while it was plugged into my Mac and I could not add files, either.

When I booted up my old PC and plugged the external into it, it worked fine. So I can only assume that since I first used it on my PC, I'm having trouble using it on my Mac. A friend of mine told me something about how I'd have to reformat my computer and start over. PLEASE tell me this is not the case. Does anybody know a way to fix this that lets me keep my Mac as is and not have to delete anything?

OS X :: External Hard Drive Constantly Working / Reading

Jan 13, 2010

I recently bought an external hard drive (like 2 weeks ago)- I put two partitions on it, one set as a Time Machine backup (HFS+) and one as file storage (FAT32 to make compatible with Windows XP boot on my Macbook Pro). When I first got it, I remember being surprised by how quiet it was. I filled it up and now, whenever I plug the drive in, it makes a sound like it's constantly reading (reminds me of the sound old, old computers used to make when thinking a lot, i.e. with the blinking orange light).

As soon as I start 'using' it (for instance, turning Time Machine backup on, etc.) it suddenly starts running quiet again. I made sure to make it 'invisible' to Spotlight so it doesn't index the drive... what else could be accessing the drive and making it work so hard? The constant 'grinding' of the drive is really bothersome!

PowerPC :: Hard Drive Not Working / Logic Board Unable To Communicate With Hard Drive

Sep 9, 2009

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?

OS X :: How To Clon And Copy The Content From One An External Hard Drive To New Hard Drive

Oct 14, 2009

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.

MacBook Pro :: Cloning Entire Hard Drive To An External Hard Drive

Mar 31, 2012

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.

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?

Mac Pro :: Internal External Hard Vs External Hard Drive

Jul 12, 2010

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

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?

Hardware :: Q950 Hard Drive & Connect External Drive To IBook Or Dell?

Jan 29, 2008

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.

Hardware :: Won't Show Up G-Tech G-Drive (500GB) External Hard Drive

Jan 16, 2008

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)

OS X :: Recover Data Fom Hard Drive / External Drive Stopped Mounting

Sep 4, 2009

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!

Intel Mac :: Using External Hard Drive As Both A Boot Drive And Timemachine Backup?

Mar 8, 2012

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?

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?
