I need help retrieving Microsoft files lost when upgrading to OSX Mavericks

Question

My daughter recently upgraded our Mac to the OSX Mavericks platform. Unfortunately, all of our Microsoft files, etc. are gone! I need to know how I can retrieve these files or if I can. I'm honestly not impressed with this new platform. I need help asap and your help is truly appreciated.

Answer 1

You have to make the backup yourself. That's your only protection against file loss whether accidental or catastrophic. In fact you should have at least two of them - each done differently and on separate drives.
If your files truly were "erased" then you can see if they can be recovered:
General File Recovery
If you stop using the drive it's possible to recover deleted files that have not been overwritten by using recovery software such as MAC Data Recovery, Data Rescue II, File Salvage or TechTool Pro.  Each of the preceding come on bootable CDs to enable usage without risk of writing more data to the hard drive.  Two free alternatives are Disk Drill and TestDisk.  Look for them and demos at MacUpdate or CNET Downloads. Recovery software usually provide trial versions that enable you to determine if the software would help before actually paying for it. Beyond this or if the drive has completely failed, then you would need to send the drive to a recovery service which is very expensive.
The longer the hard drive remains in use and data are written to it, the greater the risk your deleted files will be overwritten.

Basic Backup
For some people Time Machine will be more than adequate. Time Machine is part of OS X. There are two components:
1. A Time Machine preferences panel as part of System Preferences;
2. A Time Machine application located in the Applications folder. It is
     used to manage backups and to restore backups. Time Machine
     requires a backup drive that is at least twice the capacity of the
     drive being backed up.
3. Time Machine requires a backup drive that is at least double the
     capacity of the drive(s) it backs up.
Alternatively, get an external drive at least equal in size to the internal hard drive and make (and maintain) a bootable clone/backup. You can make a bootable clone using the Restore option of Disk Utility. You can also make and maintain clones with good backup software. My personal recommendations are (order is not significant):
  1. Carbon Copy Cloner
  2. Get Backup
  3. Deja Vu
  4. SuperDuper!
  5. Synk Pro
  6. Tri-Backup
Visit The XLab FAQs and read the FAQ on backup and restore.  Also read How to Back Up and Restore Your Files. For help with using Time Machine visit Pondini's Time Machine FAQ for help with all things Time Machine.
Although you can buy a complete external drive system, you can also put one together if you are so inclined.  It's relatively easy and only requires a Phillips head screwdriver (typically.)  You can purchase hard drives separately.  This gives you an opportunity to shop for the best prices on a hard drive of your choice.  Reliable brands include Seagate, Hitachi, Western Digital, Toshiba, and Fujitsu.  You can find reviews and benchmarks on many drives at Storage Review.
Enclosures for FireWire and USB are readily available.  You can find only FireWire enclosures, only USB enclosures, and enclosures that feature multiple ports.  I would stress getting enclosures that use the Oxford chipsets especially for Firewire drives (911, 921, 922, for example.)  You can find enclosures at places such as;
  1. Cool Drives
  2. OWC
  3. WiebeTech
  4. Firewire Direct
  5. California Drives
  6. NewEgg
All you need do is remove a case cover, mount the hard drive in the enclosure and connect the cables, then re-attach the case cover.  Usually the only tool required is a small or medium Phillips screwdriver.
