MacBook Pro :: It Suddenly Won't Read My Hard Drive
Mar 24, 2012
My Macbook Pro suddenly won't read my 750GB WD Elements Hard drive.It was working earlier today but when I went to press play on my TV show in VLC it said the files couldn't be read. So i reopended them all and they still didn't work. I closed down all programs running that could possibly be using my hard drive but it said it was being used so I force ejected it and when I plugged it back in it didn't work.
It comes up with an error message "this disk can't be read by this computer" but it still shows up in disk utility. In disk utility though it says it is a 2.2TB hard drive which confuses me. also I the buttons for "verify disk" and "repair disk" are greyed out.
I have an external hard drive, it's formatted in NTFS, sort of like a 'bridge' between my Macbook and my Windows machine. I was able to write to the NTFS drive from my Mac using MacFUSE and NTFS-3G. A few days ago, the hard drive showed up as 'read-only', and is still that way now. I've tried repairing disk permissions, reinstalling the NTFS applications, nothing seems to change the write permissions back.
I've had a 1TB external hard drive for the last year and never had a problem with it until now. Suddenly, it is showing as read-only, however, it's formatted for Mac. Do I have to re-format it?
I am using an Intenso 2,5" MemoryStation as an external hard drive. I have a few folders with pictures on it and my TimeMachine. When I plug it in it would usually show up on my desktop and start backing up my hard disk automatically. Something has now changed.
My dad gave my Macbook a new hard disk with more storage. When he put it in, he first safety copied all my stuff onto a separate external hard drive - ie. not my own. My Macbook is working perfectly and looks and acts exactly like before. But when I plug in my external hard drive, it now doesn't show up, neither on my desktop nor in disk utility. I can see that the external hard drive is responding as a light switches on and off when I plug it in and out; I don't think it is broken as I have taken very good care of it.
I'm worried that I have formatted my external hard drive so that it will only respond to a (now old) backup of my Macbook, which I can't access from my new hard disk.
I do also have the external hard drive that my dad originally used to backup all my stuff - with the older backup. Is there a way I can have my external hard drive read the new external hard drive (with the old backup of my Macbook)?
I have a Seagate FreeAgent GoFlex Desk external hard drive, which i've loaded movies, pictures, videos, and documents on to. I have only used up about 100GB of 1.5TB and for some reason when I plugged it in today it wont let me load anything onto it and if you click get info on it, it says you can only read.
I recently borrowed my brother's laptop to use as a media station for listening to music from, and watching movies, in order to free up some space on my main macbook. In trying to migrate some files over, I discovered that my hard drive, a 320 GB WD Elements drive, is having some problems which I've never encountered before. It has always worked fine in the past, but now I can't transfer any files to or from it, from either computer. In all of my troubleshooting, I've gotten various errors, (-36, -50), and various messages saying how the device can't be read or written from, or how some files contian unreadable data, etc.Disk Utility found an unused node when verifying the disk, and notified me that the disk needed to be repaired.I then used Disk Utility, which said it was able to successfully repair it, but the same problem remains, and after verifying the disk, it still says it needs to be repaired.I've tried to find any files that may be causing the problem, and was finally able to delete a seemingly troublesome file that was stuck in my trash bin from the external drive after trying various apps, (ie Trash It, Cocktail, What's Keeping Me?).This didn't end up solving anything...I've used terminal to eliminate some other potentially problematic files, with no luck still, and I'm not too confident with Terminal so I don't want to be messing around too much without more guidance.
I've used Disk Warrior to try to solve the problem, but still with no success.When I use the app to Check All Files and Folders, it does so for only a few seconds, then reports that "An unexpected error ocurred while attempting to perform file operations" for several files, and that several files' "Property list is damaged and cannot be repaired". When using Disk Warrior to REBUILD the drive, the app pauses for about 15 seconds, then says that it can't be rebuilt because it is in use.Again, I've used the What's Keeping Me? app to kill any activity with the drive, and the same error occurs.I've spent a lot of time trying to sort this out.
My external hard drive has reverted back to it's read-only form after a few weeks of running fine using tuxera so I can use my hard drive with my mac. Now tuxera or similar programs don't even recognise the drive.
I have an early 2009 macbook, with 320 GB hard drive and running OS Lion, after i upgraded my os to lion, the computer ran perfectly normal, although a little bit slower than running snow Leopard. However, recently I notice my mac become very slow, got rainbow wheel even when i open the safari. then I use the black magic to test the hard disk speed, it appears the read and write speed is only a little over 30mb/s.
i have recently change my keyboard at apple store, I notice my mac slow down after that, do you think it would related?
I have an external hard drive(seagate 250 NTFS format) which i have used on my windows 7 computer now that i'm trying to load the information onto my macbook pro (10.7.4) it will not let me change the permissions nor duplicate the files. How can I be able to edit and save the information to my mac from the external drive??
Just a few seconds ago, my WD Mybook external HD wasn't recognised. The sign came up saying that you should eject your drives before disconnecting them (although I didn't disconnect it). So I unplug it and try to plug it back in and it isn't recognised. The hard drive is powered (I can hear it spinning), I tried switching firewire cables, I tried it with another computer, and it isn't recognised
I am sure this is a simple question, but I am having a problem going from windows to mac with an external hard drive. I can read and write to the drive on any windows PC. On my macbook pro laptop, I can only read. It will not let me write or erase anything to the drive. Does this have to do with the drives formatting? If so which format will let me both read and write on mac and pc?
maybe I haven't been paying attention but my HD seems to have a misc 50-150 GB of stuff on there that didn't seem to be there before, nor can I account for what it is. I have opened up the HD and gotten "info" on all folders there. The total amount of storage does not equal what the HD tells me I have. I get "info" on the HD and it says 300 GB used (20 GB left).The folders and size are as follows as listed on my HD:
For a grand total of: 190.39 GB or so (not including the 50 mb or 644 kb) I'll include what is on my desktop as well (I assume it is already included on the list above but just incase).........
I have 2 external hard drives one specifically for mac the other is for either mac or Windows base PC. I backed up on my mac using the time capsule back up now. When I attach to a usb ion my windows PC it wont read or even pick up either external discs, is this normal.  How do I get files from my mac to windows based PC, it does work using a memory stick. But why won't PC pick up the drives.

For some reason my Lacie external drive that's hooked up to my imac is constantly being read for no reason. It's never idle and never rests until I eject it. I'm afraid the drive's gonna fail soon and all my work gone? Did a search but can't find anything online.
What is the standard tool to test your hard drives read/write speeds? I'd like to test my new SSD to see how fast it really is. I've heard you cant trust XBench for that which is the only thing I have to use.
I recemtly purchased a G4 at a local thrift store for $10. After repairing the processor and installing and updating os X 10.4 on a 20g drive I added and additional 100g drive for music and videos. The 20g drive read/write is fine and writing to the 100g works fine also. When attempting to view videos located on the 100g drive, the system hangs. when using itunes it must rebuffer every few seconds.
I just had the hard drive replaced in my IMac and it only at 1 to 1 or maybe 2 to 1 speed. my old one did over 10 to 1. car it be speeded up? Any way to get hard drive to read/ write faster?
I bought a Seagate Free Agent Go Flex External drive. I transferred all my files from my previous external HD.
When I went to access my folders on my external HD, the folders are all locked, with Sharing and Permission section in the Information "Everyone: Read" only! I can't change any of the information or move things! All of them are locked and "read only." I know how to change it, but only manually, individually. I have several hundreds of folders and I don't want to manually change all of them to "Read & Write." Is their a way to let me re-set the folders to "Read & Write" easily??
I'm both elated and pissy at the same time. Something happened to my mac when I was traveling, be it a latent hardware flaw, damage, or some other random act, and my mac OSX partition just, well, died. Unbootable, disk utility spends over a day trying to fix the boot record. The Bootcamp windows partition is fritzy, but it at least mounts and periodically can be booted from. I bought an external usb hard drive, loaded SL onto that, and have my mac back up and running again, but no data to speak of. So based on numerous recommendations, I paid good money to purchase Disk Warrior 4. Nothing, just told me the Macintosh HD partition on the hard drive was damaged, but that bootcamp could still be read.
Ok so I have an 8800 GS imac, 3.06 intel core 2, 4 gigs ram. Running snow lepord. I need to resolve an issue where I can not get into OSX. At first I got error messeges saying my external HDD could not read, now it looks like its my primary drive because when I restarted I got the progress bar under the apple logo, indicating that something is wrong with the OS. The bar when to full 100% but then I got stuck at never ending spinning wheel. I restarted and no more progress bar but still the spining wheel of death. I really dont mind refomrating its just that I had some important text documents and other files that I cant get back without recoving them some how. How to proceed? I held down cmd v or s (i forgot) on startup and got a black screen with several problem statements. One reads the system boot strapper has crashed trace BPT trap.
Recently my computer has been slow, having freezes, endless colorwheel/beachball, etc. I've deleted the whole disc and rewrited 0s to it, which fixed a bad sector error and seemed to help but its still freezes oftenly. I have come to the point where I think the HDD needs to be replaced and theres nothing else I can do.

I have stuff on it that I'd rather not lose, any advice
Got a new MBP last month to replace my white MacBook - loving it as an upgrade but one gripe - if I'm sat using it on my knee I regularly hear the "click" type noise of what I imagine is the protection of the hard drive because it thinks it is being dropped.
I never heard this on my old Mac and while it's not a huge issue it is a bit disconcerting, as though I'm being told off for moving it in a fairly responsible way.
If I have iTunes on an SSD drive (the boot drive in my Mac Mini), can it read the music library on a second rotational hard drive? I'd like not to have the large music library on a 120GB SSD drive.
I have an aluminum unibody macbook from October 2008. I'm looking to upgrade the 160 GB hard drive inside to a 500 GB one I'm considering from Newegg. Would it be possible to migrate/copy/clone the entire contents of my current hard drive to the 500 GB one? I also have a section of my current hard drive partitioned for Bootcamp. Would this affect my ability to transfer everything over?
If this is possible at all, how can I go about doing so? If there are steps laid out somewhere, I'd appreciate a referral. Sorry if my question is a little elementary, but I did a search on these forums and also google and nothing really came up
This is a very specific problem that I'm sure other 17" MBP users have. I bought a 17" uMPB a few weeks ago and after a fair amount of use I am started to get a bit of eye strain from trying to read the text on the screen. I understand that the text size (as well as palettes, other windows, etc.) are smaller because they are taking up the same number of pixels on a higher dpi screen (I believe the WUXGA MBP screen is 136 dpi). So it makes many things difficult to read. I have tried TinkerTool to increase font sizes.
But many things in the system appear to remain unchanged and things such as dialog windows are still very small. I really want to increase the size of the text globally but there doesn't seem to be an easy solution. I would not consider lowering my resolution simply because I want to be able to view my pictures and high def videos at native screen resolution. Is there an easy solution to this? Please don't post things like "just zoom in by holding ctrl and scrolling" because I know that exists, but that's a workaround. These are my google findings for my problem. [URL]
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.
