As I recall, LBA started showing up in the mid-90s so I'd look for
drives that were manufactured in that timeframe
Quantum ProDrive LPS, or any Apple-labeled ATA drive.
I think <1gb are starting to dry up, haven't seen many at Weird Stuff
in a while.
There should be tons of them out there somewhere coming out of Performas.
I have a large collection of known good old drives to pick from and that
general answer
does not hold for the Quantum prodrives LPS105 series below 500mb and my
collection
includes a good handful of common sizes in the 60-340mb range! I have a
cross section of
drives that range from small 20mb IDE though 500mb amounting to about
80-100 drives
with a large portion of them in the 100-500mb range. So I'm not
concerned with market
drying up as my supply is sorta guaranteed.
The problem is without testing every drive not all (many) of the drives
less than 500mb
supported LBA. Some had alternate structures available but without
LBA. It's in the
same category as 8bit transfer support... in the spec not often seen in
the wild.
While there are random claims of drive less than 500mb having LBA
support data
sheets with info that might confirm it are vague or blank on that
information.
For PCs this was a non issue before 512mb. For drives in the 500-1gb
range
there were three schemes, CHS with artificial geometry support, Large
bit shift, LBA.
I may have to read the feature data on all of them and see... a horribly
time consuming task.
Or just save them for random use and go CF as I can still find small
ones (64mb to 1gb).,
