Modern hard drives use up to several hundred Megabytes of their own capacity for software in order to control and mange the containing processors, operating system and processes.
Attingo is able to
Generally speaking, software is error-prone. This can sometimes even affects every single drive of a certain series. Usual indicators are a wrong capacity shown in the BIOS (e.g. 0 MB) or cryptic model or serial numbers.
The commands necessary in order to communicate with the firmware depend on the manufacturer, model and firmware version. Attingo has nearly every firmware version reverse engineered and can directly access it, manipulate parameters or patch it so the data can be recovered.
A firmware error may also be caused by an overflow of the defect list in the service area, caused by defective sectors. This combined error pattern - defective sectors and firmware error – often occur together. In this case the hard drive can no longer be used after the data rescue.

If a Seagate hard drive is not recognized any more by the computer or a capacity of 0 MB is shown, a firmware defect is commonly the reason. Some particular Seagate and Maxtor hard drive series are affected.
Attingo is able to repair defective firmware (e.g. SD15, SD16, SD17, SD18, SD19, SD25, SD35, SD45, SD81, SD1A, DE12, HP12, MX15). Normally all the data can be recovered that way. Furthermore we update the firmware to an error-free version, so that the hard drive can be continued to use afterwards. Affected are the following series:
With numerous modern Western Digital hard drives, a certain behaviour is caused by the first physical read errors: The transfer rate decreases drastically, accessing folders takes unusually long and bigger files occasionally cannot be opened any more. Attingo has methods to recover data from such affected hard drives.
