Before it lands in the archive, I have to put it here too …
It is a hard drive from the 90s (exactly 21.10.1991) – namely a 2.5 inch disk from Seagate with the incredible storage capacity of 85.3 MB (yes MEGABYTE). In comparison, a 160 GB (Gigabyte) disk from Fujitsu in 2007.
The Seagate disc with the designation ST-9096 was installed in a Commodore Amiga 1200. It kept the complete Amiga OS 3.1 including plenty of applications space. At that time you could not get that 85MB so easy.
To the technical data: If you want to format it today, you should know the following parameters: 980 cyl, 10 heads, 17 sectors gives a capacity of 85,299,200 bytes. The HDD has a power consumption of 2W in read / write mode and 1W in idlemode. 300mW still consumes it in sleep mode.Interesting is perhaps even the size comparison to current records.
The interface complies with the IDE standard (Integrated Drive Electronics).
