Few facts about 5Tb Seagate Hard Drive recovery and data restoration
Here are few instances of most recoverable in our lab hard drives of this kind.
Desktop HDD ST5000DM000
This device is a heavy duty 5TB 3.5-Inch internal Hard Drive.
Disks and Heads
Three Disk platters rotate at 5900 RPM. Six head for reading and writing the data to 9,767,541,168 available LBA sectors on disks. Data density is up to 1TB-per-disk (AcuTrac servo technology) require careful data extraction procedures.
Printed Circuit Board
Circuit Board (PCB) has 128 Mb Buffer onboard memory chip and SATA 6Gb/s connector. PCB numbers are different and depend on specific part number and firmware type. For example, PCB 100721570 is installed on ST5000DM000 with PN: 1FK178-568, FW: CC49.
PCB failure is extremely rear event and almost never causing data loss, unless original microcode in onboard ROM is destroyed or erased intentionally.
Data Recovery Chances and Rates
A solid, heavy duty mechanics and reliable electronics may keep this 3.5-inch hard drive running flawlessly for years. However, when sudden jolt (or a drop) forces the heads to make a little scratch, situation may change drastically in few moments. Immediate clean-room surgery may be the only chance to retrieve most of files before it’s too late.
Few facts about ST5000DM000 failure
- The clicking is the most dangerous symptom. Immediate internal parts inspection is required. Any further power-ups will render the disk surfaces to scratched and unrecoverable.
- ST5000DM000 firmware is locked to prevent unauthorized recovery attempts.
- Silent spinning is good symptom for fast and successful data recovery from such failed HDD, but to prevent more damage the drive must not be in use.
- Silent and non-spinning disks: the problem might be very serious, related to stuck heads.
- Any attempt to repair ST5000DM000 outside of professional laboratory may render this drive to unrecoverable. Do not allow opening the drive outside of specialized data recovery lab.
