I have limited experience with troubleshooting PC's. Please share with us the software's that you use in the diagnosing/troubleshooting/repair/data recovery, etc. of PC's. Here is a small list that I have started: 1. Hard Drive/Partition Imaging to allow for backing up of all files on a system which is not bootable, allowing the System Partition to be wiped/formatted and the OS re-installed. My preference would be to use Image for Linux. 2. Hard Drive Diagnostics a. Hitachi's Drive Fitness Test (Works on all manufacturer's hard drives) b. Seagate's SeaTools (Works only on Seagate & Maxtor hard drives) c. Western Digital's Data Lifeguard Diagnostics (Works only on WD HD's.) d. Samsung's Hutil (Works only on Samsung Hard Drives) 3. Puppy Linux Bootable CD (Would be used primarily for copying individual files from a non-bootable PC.) 4. Hard Drive Partition Management - I own a BING license so I would probably use only BING. Some other possibilities are: GParted (Puppy Linux) or Partition Wizard's bootable CD. 5. Disk Wiping before formatting and OS Re-Install - DBAN or Terabyte's CopyWipe. Thanks in Advance.
