All manufacturers end up with bad series. A few examples:
IBM Deskstar AKA Deathstar is infamous - SCSI disks from them around the same time also failed very quickly - before this IBM had a great reputation for quality disks. They sold their disk division to Hitachi global storage after this ending a long chapter in computer history - the hard disk was invented by IBM in 1956. Interestingly, disks IBM bought from a third party (CMI) for the mid-80s AT did major damage to the company - a huge number of them failed either due to design flaws in the discs or bugs in MS-DOS.
Western Digital had a terrible reputation for poor disks back in the late 80s/early 90s
Maxtor, which later got bought by Seagate, had a terrible reputation for unreliable disks (I've had a few bad ones myself) Seagate have had major firmware issues on the 7200.11 series and bad firmware on some 7200.10 models as well and in 1995/1996 the company I worked for had huge problems with failing Seagate SCSI discs.
Samsung is the ONLY current manufacturer of 3.5" disks that haven't (to my knowledge) had an unreliable series - and I expect that is only because they haven't been a major player for long enough to have had a large number of different disks types. (That said, they did have a problem with buggy diagnostics software that erroneously marked disks as bad, even though they where not)
While it is a good idea to avoid disk families that are known to be bad, and keep an eye on firmware issues on any disks that you have, disk makers end up with a long term bad reputation for ALL their products whenever they've had a bad family, even if the problem has been resolved. While I'm sure they put tremendous effort into ensuring new models will work correctly, it is impossible to anticipate all problems, and accelerated aging won't reveal all problems and then there is of course the rush to get the disks to market as soon as possible!
