Symantec PGP whole drive encryption encrypts the entire hard drive (hence the name).With Symantec PGP whole disk encryption, the entirety of their hard drive was password-protected.PGP encryption, also known as Pretty Good Privacy encryption, was invented by Phil Zimmerman in 1991.
Symantec Recovery Disk Software That UsesTechnology companies such as Symantec offer software that uses this strong encryption method to protect users data.PGP encryption helps protect the data on your hard drive from unwanted access. But it doesnt protect your hard drive from any physical or logical damage. When this clients laptop failed to boot up one day, the client removed the hard drive. They found that the drive grew very hot when they tried to power it on, and could not get it to detect on another machine. The client quickly contacted our recovery client advisers here at Gillware Data Recovery and send the hard drive to our data recovery lab. PGP Encrypted Hard Drive Recovery Case Study: Laptop Not Booting Drive Model: Hitachi HTS725050A7E630 Drive Capacity: 500 GB Operating System: Windows Situation: Laptop became very hot and wouldnt boot Type of Data Recovered: User Word and Excel documents Binary Read: 67.2 Gillware Data Recovery Case Rating: 9 Firmware and Parts Compatibility Issues When our data recovery engineers inspected the clients hard drive in our cleanroom, they found that the drives readwrite heads had crashed. There was some moderate damage to the drives platters as well. Even when two hard drives share the same model number, they are both still special snowflakes. Each hard drive has to be calibrated in the factory for its unique tolerances and minor defects separately. The calibration makes sure the drives internal components work properly, according to its unique differences. The calibration data is stored in a ROM chip on the drives control board. A hard drive will never truly behave optimally if it has another drives readwrite heads inside it. This is simply because the drives calibrations just do not line up with the unimaginably tiny variations between the two sets of readwrite heads. This hard drive was particularly uncooperative with our engineers. Normally, when a hard drive powers on, its readwrite heads find the firmware, read it, and store the data in the drives RAM before continuing its normal operations. They could read the firmware, but our engineers had to manually load it into the drives RAM. Due to adaptive drift, it took multiple sets of donor heads to read this hard drive. As a repaired hard drive continues to operate, its operating conditions change. When the conditions shift too far, the hard drives replacement parts become incompatible, and must be themselves replaced. Eventually, after multiple donors have been used on this drive and the drives condition had continued to degrade, we had gotten all we could get: 67 of the drives binary. ![]()
