I have a Seagate hard disk. Usually, the Seagate hard disk drives have firmware updates, some of them very critical for the saved data. Some years ago I had to recover a Seagate hard disk because the firmware had a problem and the hard disk headers were unaligned with the data. Now, I try to have the hard disk firmware updated.
The main problem is that some Seagate firmware updates use a CD-ROM, but my computer do not have CR-ROM.
This post shows how to update a Seagate hard disk firmware using a USB dongle.
