Lost data? Your next steps are critical!
To avoid permanent data loss, follow these important guidelines and tips:
1. If your drive is making clicking, grinding or whirring sounds, shut down your computer immediately.
These sounds could be the read/write heads hitting or scraping the platters. Severe or complete data loss could result.
2. Unplug the power to the computer before removing the hard drive and handle the drive carefully. Hard drives are extremely sensitive to static electricity and physical jarring or jolts.
3. If your data is critical, make sure you choose a reputable recovery firm that can properly recover data from physically damaged drives. Even the simplest recovery attempts on a physically damaged drive could render your data unrecoverable.
When disaster strikes:
1. If possible, back up the data immediately
2. Do not use utility software if the drive makes scraping, tapping, clicking or humming sounds
3. Do not power up a device that has obvious physical damage or is making unusual sounds
4. Shut down the computer to avoid further damage to the drive and its data
5. Do not attempt recovery yourself on severely traumatized drives (i.e., turning the computer off and on,
Preventing data loss
Everyone should adopt strategies to ensure critical information is protected from corruption and loss.
1. Never upgrade any system without a verified backup
2. Use up-to-date hardware and software utilities for data security, such as firewalls and virus protection
3. Scan all incoming data for viruses, including packaged software
4. Use ventilation, fans and/or air conditioning to keep servers at the proper operating temperature
5. Connect systems to an uninterruptible power supply (UPS) to protect against power surges
6. Power down and take extreme caution when moving computers
7. Avoid static discharge when touching or handling the media, especially in excessively dry environments
1. Invest in redundant backup systems
2. Establish a structured backup procedure to make copies of all critical data files, using software
3. Periodically test the backups to verify that data, especially databases and other critical files, are being backed up properly
4. Keep at least one verified copy of critical data offsite
