I have the same model of Macbook which was showing the same issues. After replacing the Harddrive with an SSD I still had the same issue. It ended up being the SATA cable connecting the hard drive to the logic board. Over some time the insulation had started to wear off and the cable was occasionally shorting against the base of the case causing IO errors. ...

No, if you move the files back to another location on the disk backed up by Time Machine, the next backup will create a new copy of these files on your backup volume. This may even occur if you put them back into the same place (because the files will get a new creation timestamp which AFAIK triggers Time Machine to create a new file on the backup drive). ...

From Apple KB : Backup disks you can use with Time Machine Formatting a backup disk for use with Time Machine The most common format for a Time Machine backup disk is Mac OS Extended (Journaled) format. Time Machine also supports Mac OS Extended (Case-sensitive, Journaled), Mac OS Extended (Case-sensitive, Journaled, Encrypted), and Xsan ...

Every backup is a full backup. Your destination has hard links to each file so that if you copy any snapshot to another volume or folder - you have a copy of every file. If you delete a file from one time interval - the other intervals lose no data. As implemented, there is no reason to store duplicate bits on e destination if a hard link suffices to fully ...

The Mail.app stores all Messages in your User Directory: ~/Library/Mail/ Depending on your OS Version there is a Subfolder, f.e. "V3" for 10.11 and "V2" for 10.10., containing Subfolders for each Mailbox. The Library Folder is usually hidden, but you can access it in the Finder from the Menu "Go to" > "Go to Folder" (or CMD+SHIFT+G) and typing in the ...

There are two ways of having backups encrypted. First, Time Capsule allows for you to encrypt the disk. If you enable this, the disk can only be mounted by the device if you provide it with the password to do so. This encryption is local and thus doesn't address your concern. It does mean that if the disk somehow gets taken out of the TC, it can't be read. ...

You can actually restore mail messages directly inside Mail. Make the Mail application active, then enter Time Machine via the menulet. Works similar to file recovery in Finder.

I have the same MacBook Pro. I did the following: I bought a SSD and replaced the hard drive disk. I installed OS X on the SSD. (240 GB - $100). I inserted 8 GB of RAM (replace the two 2 GB RAM) ( 2 x 4 GB - $50). Then I replaced the SuperDrive with .... the old HDD. You need to buy an adapter. (Adapter on Amazon - $30). Yes it's expensive, but it takes ...

First, Some Diagnostics While SSD's will give you a boost in speed simply replacing one with the hopes it solves a problem could get expensive. Let's verify that the problem is the drive in the first place and not something else. If you can log into your system, open Terminal and issue the command diskutil list You will get a listing of all your drives ...

Yes, when you go to the Time Machine preferences, just select Use Both when adding the additional drive. From: OS X El Capitan: Use multiple backup disks Time Machine rotates the backup schedule among the disks. For each disk, Time Machine backs up everything that’s changed since the last time that disk was used. If you designated items that shouldn’t ...

The file that contains the serial number, if you still have it, would be here: Macintosh HD/Library/Preferences/com.apple.QuickTime.plist *NOTE: This is the main Library folder, not your User folder Library.

I don't see why one would have anything to do with the other. Drives are not being constantly read from and written to unless something needs to do that. You can play a video game and once it's in RAM it'll stop reading the hard drive in many cases. A large movie on the other hand will constantly read from the hard drive. But even still, Time Machine and ...

In general, I would think that a slow Time Machine disk is not going to really affect the performance of your machine. If you are using the 5400 RPM disk only for Time Machine, then the performance of that disk is only going to affect the speed that backups are made and recovered for the most part. It is true that when TM is running it is scanning your hard ...

I have a Mac Pro 2008 running El Capitan and also experienced slow downs with Time Machine. The slow downs had nothing to do with hard drive speed. I had never used Time Machine until I downgraded from Snow Leopard to El Capitan. I made a mistake and let Time Machine try to back up all connected drives. (I have four internal hard drives, and two external ...

In your situation, I'd try doing a backup with Super Duper. www.shirt-pocket.com/SuperDuper/ It will be a full backup, can go on any drive with enough free space for the backup, and takes you away from any possible issues with Time Machine.

If you want to do a mirrored backup use something like rsync or Carbon Copy Cloner. Time machine's mission is to make incremental backups every hour so you can browse and restore old versions of your documents. It wouldn't be my choice for making a full mirrored backup of a hard drive. Rsync is built in to OSX so the price is right and it can synchronize ...

You will diagnose that you have a serious disk problem by looking at /var/log/system.log and more specifically with: grep disk /var/log/system.log These error messages will clearly show if your disk is producing I/O error on the same location, which will indicate a disk problem, or on multiple locations which will indicate a bus or logic problem. I ...
