Unfortunately you may have hardware issues if yours is an "Early 2011" model, many owners have reported symptoms similar to yours with the culprit being failed ball grid array solder on the graphics processor. There's some info here. The article has a link for a utility that will allow you run solely on the integrated Intel HD3000 graphics so at least you'll ...

We just has a similar issue last week at our office. Do you need to retrieve any of the data from the drive? If not: 1) Run Internet Recovery so the Macbook is not running off of the active drive (command+r at boot) 2) Open disk utility -> select drive -> partition -> 1 partition scheme, set format as appropriate, etc. 2.5) (if 2 fails) Go to Erase -> Name ...

Just let it sit - I have the same EXACT situation and while I was researching online, it just "popped up" and was available. It seemed like my good computer was trying to fix the bad computer first, before it mounted as ext hd. Hope this helps.

insert Guest Additions CD image.iso corresponding to your version number http://download.virtualbox.org/virtualbox/ worked for me once I unmounted USB from host OS launched VB, went into settings adding the USB filter and pointed to desired USB, launched VB, logged in to windows, voila, right there in computer devices as Drive (E:)

The issue persisted across multiple macs but Windows 7's Disk Management tool didn't seem to have any issues creating a new partition table. Afterwards the drive worked as expected on OS X.

You could do worse than to try dupeGuru, available from Hardcoded Software, I've had very good results with it. It presents numerous options for fine-tuning your search and will perform byte-checking comparisons. In addition to the standard dupeGuru there is a music edition as well as a picture edition for more specific media searches. It's free so give it ...

If disk utility does not even see it the electronics in the drive may have failed. System Profiler may show a drive there but if disk utility cant access it, well... "Houston we have a problem." If it IS an external you could try unplugging any other USB devices and/or trying another USB port and possibly even a different USB cable. If you can easily open ...

I can speak from experience - I've got a 32GB USB drive, 8GB of which are a Yosemite installer and 24GB of which are normal storage. It works perfectly!


1

The only conclusion I can draw at this moment is that OS X Yosemite does not support hard drives larger than 2TB. Very wrong. Yosemite supports drives up to 8EB (exabytes. Or 8 million terabytes. You could download the internet with some room left over). What it has problems with is proprietary file formats from other companies, esp. if the patent ...

I read on another forum that there is an issue with Yosemite reading Windows formatted exFat drives. I don't seem to be able to find any workaround, so I am faced with the only viable option I can see: which is to copy stuff on disk to a Yosemite formatted hard disk. I don't know how Windows reacts to Yosemite formatted exFat drives, though.

I had this same problem and it seems that the drive may have been underpowered. I may be wrong, but I got a powered USB hub and a new surge protector and everything worked out.


2

I suspect Windows` chkdsk or another Microsoft tool to erroneously repairing the partition table of your device containing the EXFAT volume. The result of sudo gpt -r -vv show /dev/disk2 of my 4 TB device created in a VM and formatted with Disk Utility in comparison looks like this: gpt -r -vv show /dev/disk2 gpt show: /dev/disk2: mediasize=4000655081472; ...

There are quite a few causes for the SBOD (spinning beach ball of death), but you'll have to narrow them down to figure out what you need to do. Possible Reasons: You are maxing out your CPU You are maxing out your RAM Your hard drive is full You have malware Now, with what you put in the question, I think the most likely answer is that your hard drive ...

If you're content with your current computer, upgrade to a SSD. I did this with my 2011 MBP and it's like I've got a new computer. I was always encountering a beachball doing anything and now I never do unless Yosemite acts up.

I have that same model and have a 240GB SSD from OWC in it. Have had for probably two years. It works very well and since you just need a 3G model you can get one for like $125.00 or so.

Yes, that drive will work for your Macbook. However, keep in mind that your machine uses a SATA II interface. This means that the maximum throughout is 300 MB/s. Though SATA III drives, such as the one you link to, are backwards compatible, there’s no benefit to spending the extra money. You are better off finding a SATA II SSD. Either way, you will notice a ...


1

Yep it'll be compatible, your HDD is a SATA II. But because of the SATA2 limitation (~300MB/s) you won't be able to use your SSD at full speed.

You mention "unlocking" the drive which would suggest your brother is using filevault (the drive is encrypted). If the drive/file system is indeed damaged, I find it unlikely you will be able to recover data. If your brother happens to be using an "old design" MacBook Pro with a non-ssd harddrive, you can still pull the drive out quite easily and connect ...

The drive will fit (2011 MBP uses standard 9.5 mm thick drives) and it is a SATA II drive that will work nicely with a SATA I port on the 2007 MB thanks to backward compatibility.


2

The only limit would be with the format/filesystem the operating system uses. You should be fine to put in whatever size drive you want, as long as it physically fits and uses the correct interface (e.g. SATA vs PATA).

Yes, you can replace the hard drive in an iPod Classic. There is no need to replicate anything on to the drive as all the OS is stored in firmware separate to the drive. Once there is a blank drive in the iPod the firmware will take over. Instructions are here at iFixIt. Mounting the Classic to take a backup is another question entirely. Since you can't ...

I just made an installer image for OS X 10.10 to install in a virtual machine and it's only 5268873216 bytes or 4.90702 GB in Base2, in Base10 it's 5.27GB. So you could have made it smaller. Not sure if you can resize it, you can try and if not delete it and start with a smaller partition. BTW There does need to a just a bit of free space as it's written ...

Onyx offers the option of hiding and revealing files, folders and volumes. You'll want to select the Utilities section and then Visibility. This may help with your visibility issue. If you can regain visibility you should be able to select the mounted volume and bring up its info (command + i), then tick the "Ignore ownership on this volume" box. You could ...

My iMac 27" 1TB HDD died, and we phoned around for a replacement HDD. We were offered on many occasions to take the machine in to them to repair ... for $600 !! Well we bought a new 1TB HDD as per recomendation, as utilized the power of Google and YouTube. We taught ourselves how to replace the HDD, and did. However, with an unfomatted HDD the iMac could ...

The only measurable difference aside from storage space is that the SSD version will be slightly more secure from data loss from the occasional fall. SSDs don't suffer from disk drive failures of scratched disks. But if your not clumsy, that's not a problem. Go with the 1TB drive. 128gb is pitiful in this day and age.

In my opinion "TestDisk" hosed your GPT. Please compare the TestDisk result with my disks. The disks in my example are equally sized, disk0 contains a CoreStorage partition and disk2 an old-style JHFS+ partition. I'm using two separate disks because it's unknown (at least to me) which formatting type (CS or JHFS+) was used originally. The PMBR/GPT and the ...

If you want to put your most-used files on the SSD and the less-frequently-used files on the HDD, you could make your own Fusion Drive. I'm paraphrasing the instructions here: Take a Time Machine backup of everything. THE FUSION DRIVE-MAKING PROCESS WILL WIPE BOTH DRIVES! Make a bootable OS X USB drive. If you can't, that's fine, but doing so will let ...

The Trim command helps with “garbage collection” of deleted data, resetting those now-unused blocks to an empty state at the time of file deletion. This allows for better performance for many SSDs, because waiting for the next write operation that requires use of that space to reset the blocks can significantly lower the speed of the write operation. ...

The TRIM command was introduced to facilitate “garbage collection” of deleted data, allowing the SSD to reset those “unused” blocks back to an “empty” state. This allows for better performance for many SSDs. All Chameleon does is hack your SSD to enable TRIM. What the hack does is basically tell the OS that the non-Apple SSDs in the system are Apple drives ...

There are three ways to handle corrupted Time Machine backup drives: (easiest) Forget about the backup. It's a backup - you are not losing anything. Just erase it and start again. Copy the final backup (or just the parts that are really important) to other media. This can be done in the Finder, and it requires about the same space as what is currently on ...

Try and format the disk by using Disk Utility built into the installer (Utility > Disk Utility) then try and reinstall. This should work since 'Macintosh HD' is only a volume and not the actual SSD. I used this method to fix the b-node tree error or whatever it is where I couldn't write to it.

Copying the entire drive is a really bad idea for several reasons. Copying it to the cloud is also a bad idea. Buying a new TB or larger drive is far cheaper, faster, and easier and would let you just start backing up and put the "corrupt" backup on the shelf until you're sure you don't need to recover any files from it. Due to the hard links that are ...

Simply… Both SSD first - having that for your swapfile will immediately appear to 'speed up' the RAM, just because access times will be much faster. RAM second - as more RAM/less pagefile will be faster still. Rough prices… 500 GB SSD - $200 4GB RAM - $33 Source ...

I am not sure if I found a real solution or not, but I've got my computer working properly again at least for the last few days. I believe the problem is mechanical; the contact between the hard drive and the logic board is not great. I hypothesize that it's something to do with batteries expanding somehwat inside the case, causing problems, but it could ...

Depends on what you're hoping to gain from your upgrade. An SSD will load everything faster, but RAM can keep more stuff open at once. If you find your computer being unbearably slow in literally everything it does, an SSD is the way to go, but if, for example, your computer only starts acting up once you open your "lots of tabs," you'll want the RAM boost. ...

Go to Crucial.com (or any other similiar site that sells ram and ssds) and check out prices. Ram is a LOT cheaper than getting an ssd. If you can afford both, get both. If you're running Yosemite then 8gb will make a marked difference. If all you're doing is surfing the internet then go through your hard drive and free up a load of space, a cheap usb drive ...

Just did SSD upgrade on 2012 MBP non retina and it flat flies now. Was gonna do ram but my graph is low mostly it's just HDDs are sooo slow. Love it now!

Open up activity monitor and check your RAM usage. If it's high pressure (check the graph), or even swapping files, you will benefit from more RAM. Any computer will benefit heavily from installing an SSD. Expect everything to go 10x faster (not kidding). Also, it will make you not having enough RAM less of a problem, as it will speed up your swap. So it ...

It depends on your budget. If I were you, I would upgrade both RAM and change 512 GB SSD. There is also Super Driver bay to SATA HD adaptor available. You could put your HDD there.

I've never tried this, so it's a theory only - Copy the backup to a sparse bundle disk image Launch Disk Utility. From the Toolbar, select 'New Image' In the Create dialog, set size to be sufficient to contain the entire backup you wish to create [it will start smaller & grow to that maximum size as you fill it.] Format - Mac Extended (Journalled) ...

The official answer from Steve Chambers will work in almost all cases. It's been a year, so the details aren't fresh in my mind. But for some reason still, I could not access recovery mode! What I ended up doing was installing an older version of Mac OS X by DVD (Snow Leopard is what I used). The install would fail, but it would set up a recovery ...

If your drive is corrupted in any way you probably don't want to use it for backup purposes any more, unless the data is not of great value to you. Apple does not allow an easy transfer from drive to drive regarding backups. I think this is due to the way TimeMachine works (As stated in this apple discussion thread) Now how to do it anyways ? I would ...

Based on your "diskutil list" it looks like your partition map is gone. This will most likely warrant data recovery options. You could try using Data Rescue (http://www.prosofteng.com/datarescue4/ or something like it) and Target Disk mode to scan it yourself - if you have a second Mac. But if the disk is physically failing (which it appears to be), the ...

disk0 - visible in the pic and the output - is the recovery system you booted to in Internet Recovery Mode and it's no real disk in the sense of a HDD or SSD. All other disks (disk2 - disk11) are related to this recovery system. Essentially your HDD, the SATA-controller or the SATA-cable is dead. You may open your MacBook Pro with this guide or another one ...

If you happen to have a thunderbolt cable and a spare mac you can try your luck with target disk mode. Target Disk Mode is a feature that allows a Mac to act as an external hard drive.

Your MacBook isn't the weak link in the chain, it's your external hard disk. The 2011 machines don't support USB 3.0 so you're either using Firewire 800 or USB 2.0 - the fastest throughput you're going to see on FW800 is around 95MB/s for RAID 0 HDDs and SSD devices. More RAM will help with overall speed, 16GB is supported, but fitting an SSD and using it ...

You've selected the Master Boot Record option. Only 4 primary partitions are allowed. disk2s5 and disk2s6 are actually extended partions. You cannot change the name conversion via DiskUtility.

There are no obvious reasons to convert parts of the main drive(s) to a CoreStorage scheme - except for Fusion drives and FileVault 2 encryption - until now. To convert your classical to a CoreStorage scheme boot to Internet Recovery Mode, Recovery Mode or an external bootable (thumb) drive, open Utilities/Terminal in the menubar and enter: diskutil list ...

Disk utility can't resize the last partition on a drive. One way would be to use GParted to move the partition and then resize it. Boot the Mac with a Ubuntu Live CD. Run GParted and move the second partition to the beginning of the free space; Reboot to Mac OS X. Verify and repair the external disk with Disk Utility. It found a minor error on the volume ...
