I'm having a weird problem with my hard drives.

I can see 2 of my 3 external hard drives in finder. All three show up in disk utility and I can access all 3 just fine but the third doesn't show up on the side bar or or in any of the drop down lists. I've already checked the finder preference boxes to show all the drives and restarted but this has been persistent. Anyone have any ideas? Thanks!

Open the AppleScript Editor in the /Applications/Utilities/ folder and run:
tell application "Finder" to quit
do shell script "chflags nohidden " & quoted form of POSIX path of (choose folder with invisibles)
delay 2
tell application "Finder" to run

Having problems with External Hard Drives on my Laptop

Ever since using linux i've always had the same problem. Whenever i connect a hard-drive, it keeps disconnecting/ spitting input-ouptut errors.
I thought it was because of the hard-drive failing, which turned out to be the problem with my last two, but i'm using another one (Seagate MomentusXT 500GB) and i'm getting the same problem.
I had just reformatted this hard drive from NTFS to Ext4 using Gparted, so maybe that's the problem? I'm really kind of lost.
I mount my HDD like this:
sudo mount /dev/sdd1 /mnt/usb
and unmount like this:
sudo umount /mnt/usb
It connects initially, and i'm able to put stuff onto it. I was able to put a whole TV series on it successfully, but when i tried copying my music onto it it failed and alot of the music didn't copy, giving me these errors:
ile system

I can then unmount and mount the HDD again, and try again, but i keep getting the same problem.

Anyone know how to fix this?

There is a whole lot of bad going on there.
There are problems both drive errors and USB errors. I don't believe it.
I have a hunch the drive is starving for power.
USB devices are supposed to function all the way down to 4.25V. Not all do.
USB ports are supposed to be able to deliver 4.25V at the end of the cable at 500mA. Not all do.
USB 2.0 devices are not supposed to draw more than 100mA unless they negotiate for more. Some violate that.
USB 2.0 devices are never supposed to draw more than 500mA. Some violate that. Especially disk drives.
My guess is that your drive is drawing excess current and the voltage drop through the port and cable are dropping you below 4.25; or at least below the voltage that your drive goes "Tango Uniform"[1]. Does your drive have the option for external power? If so try it. Following up on wtx's comment; USB 3.0 is capable of delivering more power. Also, some drives have used a cable that violates just about every aspect of the USB specification: A "Y" cable that plugs into two host ports to provide more power to the guest. I despise this solution with every fiber of my electrical engineering existence; never-the-less, you might try one.

Error code 36 (problems with external hard drive)

I have just upgraded to Yosemite and am now having major problem with my external western digital hard drive. I cannot create new folders and when I hit command N I get error code 36. I also cannot move files from one folder to the next. When I try to move them I get the error message: "The operation cannot be completed because a file of that name already exists" and that simply isn't true. None of the files' names exist in the other folder.

Ok, It appears to be the fault of Western Digital. I ejected the hard drive and then plugged it back in and it said that the drive was broken but I could still read the files and it told me to save the files on another disk and reformat. So it was just a coincidence that I upgraded to Yosemite at the same time that my external hard drive broke.

Problem with External Hard Drive

Hi,
I'm having trouble with my External Hard Drive, a 300GB Iomega USB. Everytime i use it with my iMac G4 it disconnects by itself and i get the "Device Removal" message after 20 minutes or so. This occurs even though the Mac hasn't moved, the Hard Drive and its wire wasn't moved and even when I'm not doing anything on my Mac. This occurrs in all three of the USB ports even though other devices plugged into them work fine.
It's a problem with your External Hard Drive and/or its wire i hear you say. However, the External works fine when plugged into my Windows Laptop.
Any help would be much apreciated as all my music, movies and work are on my External.
Thanks in advance,
K

Hi there:
You may have to use a Mac disk utility on the external USB hard disk drive, since the error
you see is likely caused by some defect. And the symptom is in how the drive fails to mount.
Perhaps a tool like Disk Utility could see what kind of errors, but not fix them; if this is the
case, a more specific tool such as DiskWarrior (for the Mac OS your machine has) may help.
Depending on the level this problem exists, the drive may be repairable through use of one
of the disk utility type of tools; or it may need to be erased, reformatted, etc. So, if there is
some kind of error in the directory or other portion, DiskWarrior could probably fix it and not
interfere with the data on the drive... Or, that's the hoped-for outcome.
And that direction is likely one to pursue. For the sake of discussion, you - do - have extra
USB cords, just in case you have one that does not like Macs? A diabolical PC infiltrator?!
Good luck & happy computing!

Problems with second hard drive

I bought my PowerMac G5 new in 2005 and about two years after I got it, I installed a second internal hard drive. I didn't have any problems with the drive until about six months ago (which was when I moved, but I'm not sure if that has anything to do with it). Around that point, I started hearing a single, loud click followed by a slight winding down noise. Then, my computer would almost completely freeze. After a few moments, I would hear a bunch of soft clicks and my computer would go back to normal. I figured that it was a problem with one of the hard drives, but I wasn't sure what to do.
Later on, the problem got more severe, lasting more like 30 seconds. When my second drive unmounted during one of these episodes, I shut my computer down, opened the case, took both plugs out of the second hard drive, put them back in, and started up my computer again. After that, my computer was running great again. But, a few weeks later, the symptoms started up again.
So, I've gone through the same cable un-plug and re-plug process whenever the drive unmounts. Sometimes it helps and sometimes it doesn't seem to help at all. Altogether, I think that the second drive has unmounted about five or six times. I haven't had this problem at all with the original hard drive and I haven't noticed any other problems with my computer. (Well, okay, there's the rare occasion when, instead of going to sleep, it turns the screen black and puts the fans on full blast.)
Could the drive itself be going bad and it has nothing to do with the cables? I have a utility installed that always monitors the SMART status and it hasn't reported any problems. Are there any other troubleshooting steps I should take? Any advice would be appreciated. Thanks!

Before I bought DiskWarrior, I thought I'd try some troubleshooting with the software I have on hand. But while I was doing that, the problem got worse. Now, I'm having major problems just getting the computer to boot. I'll give you the rundown on what's happened. It goes through a few boneheaded twists and turns and goes on at great length, but I thought I'd relate it all in the hopes that someone can see a likely pattern.
My first thought was the Apple hardware test, which I had thought was on the Mac OS 10.5 install DVD. So naturally, I didn't see the hardware test listed under Utilities. But while I had it up, I used Disk Utility to do repairs on both hard drives (checking both the disk and permissions). It found no problems on the 2nd hard drive, but found a few errors with "leaves" on the booting drive. It also found a bunch of issues with the permissions, but I don't think it was anything out of the ordinary.
Just for the heck of it, I asked it to run the repairs again. Not long into that, I got what I think is a kernel panic (overlaid message saying I needed to restart my computer in a few languages). It also sped up the fans.
I pushed the power button to shut it down, then started it up again. I heard the startup chime, then nothing but a black screen and the ol' hyperactive fans. I went through that several times before I was finally able to boot from the DVD again. Then, I changed the startup disk back to my usual boot volume and restarted. I had to go through the black screen and insane fans several more times before I could boot normally.
Next, I thought I'd try OnyX to see what it could do. Which might not be much, but I had it repair the disks again and also had it run the daily, weekly, and monthly maintenance scripts.
I checked into the black screen & hyperactive fans booting problem elsewhere in the forums, and saw that it was recommended to run the Apple hardware test and also found the correct procedure for doing so, which was to insert the PowerMac G5 install disc (not the Mac OS X upgrade DVD) and press Option when booting. I loaded the disc, restarted, and held down the Option key, but before I could get anything to actually load, I had several more sessions with the black screen of fans.
Regarding that boot problem, I've sometimes seen the red light inside the case turn on almost immediately after I turn on the computer. Other times, it will not light up by itself. But, when I hold the power button in to shut it down, the red light briefly turns on before the unit shuts down. I've also noticed that the light on the Caps Lock button is coming on and staying on when I'm trying to start the computer.
So, after several tries, I checked my G5 User's Guide and it said to disconnect any external devices before trying the hardware test. I had a USB thumb drive plugged in and a FireWire drive hooked up for Time Machine backups, so I took both of them out. Once again, I tried starting up with Option held down and this time, it worked. The fans started running at full blast after I selected the hardware test, which I hoped was normal. So, I asked it to run the extended test and it found no problems. I restarted my computer without reconnecting anything and, at least for now, it's working normally.
Any new thoughts?

MacBook freezing and crashing/running slow, problem with external hard drive

I've been having some issues for the past couple months with my laptop randomly freezing, usually when I have a lot happening. I've ended up having to hard-restart it several times because it will just hang and I can't get into the menu at all to force quit things. In the past couple days, it's now started crashing completely, although restarting okay. This last time, though, it crashed while I was trying to empty the trash and since then it's been crazy slow and not very responsive.I tried running disk utility and ccleaner, and although they repaired some stuff they didn't fix the problem.
I think iTunes might be the issue. I was trying to move my music library when this last thing started. I have it all on an external hard drive, and I was trying to move it from one folder to another. I tried repairing the external hard drive with disk utility to see if that was the issue, but now my files have all vanished and the external appears blank.
I also recently installed BootCamp, if that makes a difference.
I'm mostly just really unsure what to do. I don't want to do anything to the external because I need to recover the stuff that was on it, but I also need my laptop to be usable.

Thanks for the response. I tried booting in recovery mode and running disk utility again and that seemed to help. It's still hanging when I plug in the external hard drive but otherwise seems to be working okay. My main issue now is the invisible files. I tried booting in Windows, planning to install Recuva to try and get the files back. However, they show up fine there. This is a relief but I'm not totally sure what is happening. I'm guessing the disk has somehow mounted incorrectly on the mac portion but I'm not sure how to fix that. I'm about to restart on the other partition and see what's going on there.

Backup problems with external hard drive

I bought a WD passport external hard drive and copied my itunes library onto a file there. I re-set the location of the library on itunes to the drive on the external hard drive. So far I have not deleted anything from my computer hard drive. However, when I am in itunes and click onto a song, nothing comes out of my speakers. Everything looks normal, as if the track is playing, but nothing is happening. I tried buying a new track off of itunes online, downloaded it, and installed it on my ipod; it plays fine, on my ipod, but will not play on the computer. Something is obviously wrong, but I can't figure out what has happened. Any help out there?
Thanks!

It sounds to me like your iMac is on it's last legs....at least the internal hard drive. If you can't make a new Time Machine backup I would advise you replace your iMac as soon as possible.
Assuming your three-week old backup is sound you should have no problems moving everything over to a new Mac. I would recommend you use the Setup Assistant that appears when you start up the new Mac (and note: It only appears the first time you start the new Mac; you can move everything over later on via Migration Assistant, but you may see issues with accounts if you opt for that route).
I don't think you need the Genius Desk for Setup Assistant. You only have to power up the new iMac, answer a few questions....select "....From Another Disk..." When it asks how you want to move everything over....connect up your Iomega external drive...and wait for it to finish. (Could take several hours depending on the amount of data you're moving).
A couple of notes:
1. If your Iomega is a Firewire drive you'll need a Firewire to Thunderbolt adapter to connect it to your new iMac.
2. If you need to load CDs or DVDs remember the new iMacs don't contain an optical drive. You would need to get an Apple SuperDrive or third part external burner if you need that functionality.
I'm puzzled by the comment made in Seventy One's post questioning the reliability of the new iMacs. I upgraded from a 24" early 2008 model to a 27" model and everything works flawlessly. I hardly ever see the beachball anymore.

Problem with upgrading hard drive in 2009 Macbook Pro with Snow Leopard

Current drive is 320gb with fresh install of OS SL updated with some other programs installed. New drive is Seagate Momentus 750, same brand and model as the old, just bigger.
I install the new drive, boot off the OS SL CD and go into disk utility. Partition and format with GUID and Journaled. Install starts and ultimately fails every time.
Tried to clone the 320 by putting it in the macbook, use the 750 via usb/sata. Drive restores, but it is unreliable in loading and stability. When it gets to the grey screen, it alternately flickers the Apple, Folder and NO sign. Sometimes it loads, sometimes it just keeps spinning. When it does load, it's slow and programs that take more power crash.
Brought it to Apple. They said it was a problem in the SMART section, so I got a new drive under warranty. This is the THIRD drive i've gotten from Seagate. Still doesn't work.
I've countlessly repaired and verified the drive. Helps to load sometimes, but not all the time.
If I put the 320 back in, everything works great.
Thanks.

Is there a quality external enclosure to put the large drive in, one that has its own power supply and not rely on the port power in the MacBook/Pro? If it is a viable drive and can actually run a bootable OS X version, I'd begin to wonder after all that.
{I'd also looked up your computer in MacTracker to see what if any limits on hardware upgrade may exist. Nothing said of direct interest to the HDD. Also in everymac.com, so there should be no surprises. Yet to have those problems is troublesome and a surprise. New drives can fail. Maybe in batches?}
And a clone of a working system for backup could be made with a utility such as CarbonCopy cloner or superduper, etc then tested as a bootable clone, with the hard disk drive tested thoroughly before use. It also is odd that a drive of that size would act up, I see drives of even larger size offered online by reputible resellers and Mac specialist companies who have been around awhile, such as OWC. I just looked to see if there was a ceiling on support of larger size HDD capacities, and 750GB is not the largest. Maybe the series you chose could be among a troublesome batch or brand.
http://eshop.macsales.com/MyOWC/Upgrades.cfm?model=302 has a variety of stuff, including RAM, HDD, SSD, etc. And their staff has people who know what they sell. Well, some of them do. I had called them on a topic several years ago and they didn't really have an answer (I was given an OWC dual HDD external drive & it had issues, but had never been used. It still is sitting as-new, w/o support; now obsolete.)
I'd try a different brand and put it into an enclosure that has its own power supply, ports for USB2.0/3.0 and FW400/800, and so on. Perhaps even an OWC line item, not that I've had any valid experience with them here in AK. And ask their people about their products, get names, finger prints, mug shots...! LOL
Good luck & happy computing!

Permission problems with external hard drive

Hello there, I'm writting you from Paris but my french is just not good enough to really explain my problem. I'm no computer expert so i might not use the right name for stuff but i will try to be as clear as possible.
I have a macbook pro 13" from early 2012 and I'm currently running Mountain lion.
At home i use an internet modem that has an internal hard drive of 250gb. and it also gives you the possibility to conect other usb hard drives on it so you can access them through wifi.
I currently have to usb hd of 1tb each, one i use it for Time Machine and so far it works fine and i haven't had a problem with it, all back ups have been done ok. In the other one i have all my films and tv shows and stuff like that and it is in this one that i have the problem. In certen files and folders i'm not able to do anything with them, i tried to rename them but it says i don't have the permission to do it, i tried to delet another one and it said pretty much the same thing, some other time i tried to move the file to a diferent folder it it would ask me for my password and after type it and press enter it would just not move them, no error messager or anything it just didn't do it. Most of the times i have a messager saying stuff about permission or things like i can't read the file. The thing i can't understand is that as soon as i plug the HD on my mac it works fine i can rename and change stuff, I noticed that some of the files and folders have a little lock on the corner, but they aren't the ones i tried to move or rename before and i tried already unlocking all of them but eventhough i manage to unlock them when i plug the HD back to the modem it keeps the same, can't rename or move, not even to the trash.
Can anyone help me out here? I'll be really thankful
Cheers!

Permissions problem with External Hard drive.

Hi,
I've been using my external hard drive for almost a year now and out of the blue last night I ran into a interesting problem. For some reason I couldn't transfer any files to a thumb drive and shortly after I realized I didn't have Read and write permissions for any files on my mac, and everything required my password to get to. I went into disk utility and repaired the permissions and the list went on forever. Upon completion of that nothing was resolved.
SO! I popped in my Snow leopard disk and did a repair of the permissions and system through there hoping that would fix it. I than booted up the main drive and got stabbed in the face with a HUGE error message upon the apple loading screen with a "MISSING DRIVER" "KERNAL ERROR" "CORRUPT FILE" etc.
I went back and did a restore from my external harddrive hoping that would work, and it did. I can access my time machine backups from my external harddrive but cannot do so through my own control.
What should I do? Should I reformat my external harddrive? Which would suck because I'm a paranoid freak and if something would happen during the reformatting I will lose literally over a year of work that is crucial.

What is that, a "clone?" What do you mean by "cannot do so through my own control."?
What should I do? Should I reformat my external harddrive? Which would suck because I'm a paranoid freak and if something would happen during the reformatting I will lose literally over a year of work that is crucial.
Again, what's on that drive? Do you have a clone and TM backups on the same external? If so, are they in the same partition?

This one says you need to repair or reformat the disk; that means your backups are corrupted.
Try to do a +*Repair Disk+* (not permissions) on it.
If there are errors that Disk Utility can't fix, or the +*Repair Disk+* option is grayed out (meaning OSX has already determined that it can't fix it), post back.

Problem with External Hard Drive - Firewire

I have a problem with a *300GB Venus DS3 Hard Disk* / USB 2.0 - Firewire 400 (not sure if 400).
I have a +Mac G4 (1GHz Power PC G4 / 1GB DDR SDRAM)+ running +Mac OS 10.3.9.+
I connect Venus hard disk through USB cable and no problem. But when I want to connect it via Firewire it doesn´t appear in the desktop.
If I go to *System Profile* it says that there is a device connected to the FireWire port but i can´t see it in the desktop and if a open *Disk Utility*, there is no other hard disk besides the internal, so I can´t mount the Venus DS3 Hard Drive.
I looked in the internet and found this page -> http://american-media.com/support/downloadDDDS2316CBK.html
I was about to download the *Firmware Update* but i read this:
AMS is not held responsible for any damage caused by misusage of this utility! Use at your own risk and be aware that your warranty might be void! DO NOT CHANGE
ANY SETTINGS WITHOUT CONSULTING TECHSUPPORT. Do not distribute or post these files on the internet!
I searched in Internet and found that many persons had issues connecting Hard Drives using Firewire port and read some tips (like unplugging all the usb firewire devices unless mouse and keyboard, disconnect AC cable, wait 15 minutes, ...) but couldn´t fix the problem.
I also wrote several emails to the manufacturer of Venus hard drives (American-Media) but so far no answer.
I would really appreciate it if someone could tell me how to connect the Venus DS3 to a Mac G4 (OS 10.3.9) via FireWire.
Thank you very much

I suspect the problem is in the size of the drive. You say the drive was formatted for Mac and Windows. How did you do that? With older Macs, there is a 128 gB limit on drive size.
Here is a link to a third party disk utility that claims it gets around the size limit:
http://www.SpeedTools2.com/
Another possibility is to connect the drive to a Windows machine and re-format it into 3 volumes, each less than 128 gB. The Mac should be able to see the partitions.
Sidebar comments:
• The way I read the information on the AMS web page that you cited, you do not need a driver. And that is consistent with my experience with firewire enclosures.
• Inside the AMS enclosure, the drive is a standard ATA/IDE drive. That you can use the drive with a USB connection is proof the drive itself is working.
• The "bridge" is a key component in FW conectivity. (That is a piece of circuitry that sits between the IDE drive and the FW connection. It is inside the enclosure.) It appears your enclosure has the Oxford 911 chipset on the bridge. That is good.

Is it a hardware or software problem with my hard drive?

A few days ago, I was burning a dvd on my Powerbook G4. It was taking a few minutes and I left. When I came back the dvd burn had completed but my screen was filled with a lot of text and codes. It was also frozen, all I could do was force the machine to quit. It said I had a corrupt stack and system failure. When I tried to restart, the computer failed to find a start-up disk. Using an option key hold down on start and the OS 10.4 installation disk I was able to get started. When ran disk first aid, the internal drive had file structure problems with bit maps and trees not large enough(??), or something like that. So I asked disk first aid to repair the hard drive. It whirred, and after a bit it said the hard drive was repaired. When I restarted from the repaired drive, things seemed ok, but not for long. Again everything froze up. I repeated the option start-up and disk repair. Again the utility found problems and repaired them. Same story when I restarted.
So next time I installed the OS 10.4 on an external fire drive and used it as the start-up disk. This seemed to work fine. After checking to make sure all my data from the failing drive was backed up to another drive (I have two ext fire-wire drives connected), I thought I would erase the affected drive and reinstall the OS. I did that, and then updated the OS to 10.4.8.
My problem now is that whenever the computer seems to be using the internal drive, whether booted from it or not, eventually something will freeze-up. Also, I am sure this drive was s.m.a.r.t. enabled, but now it says it is not smart supported. What's happening here? I do not have a hardware test in my utilities and I do not know if I have a physical problem with the drive or a file structure problem that recurrs for some reason. What is my next move??

Thanks for the Seagate info eww. My pb is a 800 MHz so I'll stick to finding a 120Gig HD. After my last posting, I wanted to make sure this hd was faulty and so I was running the computer booted up from the suspect drive. Things were fine for a while and after I had left the computer running and was away, when I came back, the screen was black and unresponsive to any prompt. I then went through 15 restarts trying to get booted up. I tried everything to get booted from the DVD drive and the OS install disk but it would go to the first screen where you select the drive to boot from and I would only get that ticking watch cursor and could go no further. Finally, I tried the restart with the command-S key route and got a disk os3 I/O error and a hfs early jnl init failed to open. I typed in fsck -fy and it seemed to run a disk repair similar to disk first aid. After a restart, I got to the finder screen but it ran very slow with that spinning pinwheel. I reset the pram again this time it said diskoS3, major 14, minor 2, HD appears OK. It then ran a little better until I was finally able to get to preferences and select the ext hd to boot from.
So now I'm able to get back online to this forum and check on the postings. And again everything seems to work fine from the ext HD. So does that confirm that my int drive is "screaming Replace me!!"
It must appear as though I am a glutten for punishment but I just like sorting these things out. Thanks for your help.

InDesign CS2 has problems with multiple hard drives

I have a mac pro that has two external hard drives attached to it. One is connected through usb and the other firewire. When ever I try to open an inDesign file on the hard drive that mounted second I get an error message. However I the hard drive that mounted first works just fine.
The error message is: "Cannot open the document xxx. You may not have permission or the document may be open already. For multi-user access, close the file and then lock it using the File > Get Info command in the Finder."
Any help would be greatly appreciated.

I've not had any such problem. It's been a while since I used CS2, but I definitely used it on computers with more than one disk attached. I don't think I had a mix of FireWire and USB drives though.

My MacBook Pro 13 inch makes a clicking noise from the hard drive and can not start up in safe mode and normal. I then ran disk utility in recovery mode and disk utility shows no problems with the hard drive. What is the problem?

Please help me, I have a mid 2010 Mac book pro with a toshiba mk3266gsxf harddrive. It started making a clicking noise and then my computer crashed. I proceeded to boot in safe mode, but it doesn't work. When I ran disk utility in recovery mode, it showed no problem with my disk. Does any one know what the problem is?

Sounds like a mechanical problem with the drive and it ruined the sectors where the Macintosh HD partition (and OS X, and files and programs) reside, but not your Recovery HD partition.
If you held command option r while booting, that's Internet Recovery and it's loaded via the Internet, not via the Recovery HD partition on the boot drive, so that could mean the drive is dead mechanically or there is another issue.
In either case the drive will likely have to be replaced, it's a matter of what occured to where and the drive state if you can recover data or not. If you made recent backups then your fine.
My computer is not working, is my personal data lost?

Problems with External Hard drive, will not mount and errors in disk utilit

i have a powerbook g4 aluminum. i have an external hard drive for it. a simple tech 100gig portable drive, almost brand new. i dont know what happened to it, but one day i was starting my computer up with it attached. it wounldnt fully start up, said "waiting for local disks" so i uplugged the external hard drive. now it wont mount and will only show up in the disk utility of my friends macbook. i tried to verify and repair, and this is the message i got.
Verify and Repair disk “UNTITLED”
** /dev/disk1s1

Im in mexico writing a book and so i really need help on this one guys.

Hi, hjbugs, and welcome to Apple Discussions. Disconnecting the drive while your Powerbook was accessing it probably caused your problem. It may be repairable using DiskWarrior or TechTool Pro, but if you don't have access to one of those and aren't going to buy one, reformatting the drive with Disk Utility may be the only other way to make it usable again. If it contains data you need to recover first (i.e., data that isn't also stored on your internal HD or other storage media), download the free demo version of one of the data recovery utilities mentioned in this thread and use it to see what is recoverable. If the files you need are recoverable, buy the full version of one of the utilities and recover them.

I'm having a weird problem with my hard drives.
