Seagate ST-225 20MB hard disk drive
#364998 - 04/07/17 07:07 PM


Doing some cleaning I found my old Spectrum 48+ (without the charger), my second and also non-working PS2 and some oddities, like this 5.25" hard disk. It's a Seagate ST-225 but I've not found much info about original release date and original prices (out of curiosity) despite the model being pretty famous as the best selling HD model ever and one of the most reliables ever too.

I found an OEM manual dated October 22, 1985, revision F. And I found a Seagate date decoder, which asks for 4 or 5 numbers, but my date code is only 3 numbers: 248. The chassis has an 87 surrounded by a partitioned circle, 12 partitions with 8 marked, could it mean August 1987?

Yet what I'm curious about is what were the original prices of these behemots. 20MB could easily store all accounting information of 3 business the size of my old company

Thanks a lot for the info! I saw some 1985 magazine ads saying 20mb HDs were around 2-3k or more. Just didn't get any about Seagate from that year.

I also got a video of how they manufactured the hard disks, assembled in Singapore. The video is narrated by Dan Castellaneta:
