I need some help!
I just bought a Seagate ST 251-1 40MB 28ns drive by mail order but while I paid
the 251-1 price I'm not convinced that I got a 251-1. The problem for me is
that there is another Seagate drive of the same capacity and nearly the same
model number, namely the "ST 251" with 40ns access time. The side of the drive
that I received is labeled "ST 251" and the top is labeled "ST 251 MLC-1".
Now, is the designation ST 251-1 a contraction for ST 251 MLC-1 or not?
If it helps make a determination, here's the diagnostic info that was provided
with the drive:

The MLC-1 is the determining factor that tells you which drive you have. I have installed several ST-251's with 40 ms access time, and they are ST 251 MLC-0's. -- Michael D.

Davis Internet: sld@beach.cis.ufl.edu I recently had the same question at the store where I work. After talking to tech support at our distributor, he confirmed what you suspect. The drive "ST 251 MLC-1" is indeed the ST 251-1. I don't know if you want to call it a contradiction but that's just the way Seagate has decided to do it. The regularST 251 is labeled "ST 251 MLC-0". If you still don't believe them(or me :-)) just run a hard disk test program. One of the many is CORETEST from Core Manufacturing(?). It not only works with their drives but also with most others. This will tell you what the access time is. Hope this helps.

The regularST 251 is labeled "ST 251 MLC-0". If you still don't believe them(or me :-)) The designation ST 251 MLC-1 does mean ST 251-1 But ANY OTHER MLC-n means it is an ST 251, not just "ST 251 MLC-0" greg pavlov, fstrf, amherst, ny
