[comp.sys.ibm.pc.hardware] How Big a Hard Drive Will Fit on an XT?

jboggs@inco.UUCP (John Boggs) (10/02/90)

I'm currently running an XT-clone with an ARC motherboard and a 20meg
Seagate hard disk.  I'd like more disk space.  What's the largest capacity
drive I can install internally in my full-size desktop chassis that will
be compatible with my system?  What controller will I need to control it?
I'm running DOS 3.3.

Thanks, in advance, for any info.

I ran Maxtor 2190 which is 133 Mb formatted.  I do not remember the 
model of the controller, but it was a regular Western Digital MFM 
controller with 3:1 interleave.  The drive was divided into four 
partitions.

I have an ST-277-1 in my XT formatted to 65MB with two 32.5MB partitions on a
Western Digital 27X card (RLL format). It is my understanding that the only
limiting factors in drive size in an XT are the controller card's drive 
capacity limit (in the card BIOS) and the drive bay of the box (I had only a
half height bay left open). I am told the 27X can address drives over 150MB
without errors.
