Seagate Hard Drive Firmware Modules http://www.dolphindatalab.com/seagate-hard-drive-firmware-modules

Seagate is one of the biggest hard drive manufacturers besides western digital and seagate hard drive

repair and seagate data recovery cases are very common within all our data recovery labs. This

article will introduce to you the basic and important firmware modules of Seagate hard drive.

There're two parts of firmware located on the platters' minus tracks and ROM chip on the PCB, we

call the part on the platter SA-service area or FW(firmware area). A complete Seagate hard drive

firmware contains APP, Cert, Cert table, ATA(7200.10 and .9 contains ATA 0 and ATA 1) and

vendor modules and ROM module. APP module: it's necessary to load within level F command

mode and it's one codes module; CERT module: it's one selftest module; CERT table: selftest

process module; ATA interface protocol module: after selftest, it's necessary to load ATA; Vendor

info module: after selftest, it's necessary to load ventor module. Seagate hard drive can work on

both normal mode and safe mode too like WD hard drive. Within safe mode, power on the hdd, the

pcb is ready but the motor doesn't spin up. When users want to read/write APP and ROM, it's

necessary to operate within safe mode. Anyway, functions within safe mode is limited. Normal

mode: most functions are run within normal mode and selftest needs to be run within normal mode

too; Safe mode: PCB mode and firmware is not working at all, when the APP module is damaged,

the hdd enters level F command mode. Dolphin Data Lab will soon release its own unqiue powerful
