A friend of mine has a 80meg Seagate hard disk that was formatted with the Ontrack Disk Manager that came with it. The problem now is that the driver takes up 200k worth of his memory! He would love to put this driver into his new 4.0 LIM/EMS 2+meg of memory so programs, like 3-d perspective in Enable3.0, will actually maybe work?!!! Any help would be appreciated. -- To live is to die, to die is to live forever; GRegg Thompson Where will you spend eternity? greggt@vax1.cc.uakron.edu

This doesn't sound right -- there must be something else using up most of that memory. You don't say which 80 Meg Seagate and what machine (I have an 80 Meg SCSI on a PC and an 80 Meg standard drive on an AT) and the OnTrack drivers don't use nearly that much. I did replace the OnTrack driver on the AT with the OnTrack Superproms which eliminate the driver, allow full use of the entire drive capacity, and work under OS/2 -- your friend might want to consider adding these if he has an AT type machine.

The problem now is that the driver >takes up 200k worth of his memory! You did not say what kind of machine it was on, but I cannot imagine the driver taking 200k. I also use Disk Manager on an 80meg drive and the total package is well under 5k. Please double check your install. ----- Kenneth W.

If yes, then Disk Manager works by faking DOS into thinking that the sectors are 2048 bytes instead of 512 bytes (If the clusters are 8K, then you know that's what is happening). Now DOS has to allocate disk buffers which can hold those 2048 bytes, so a BUFFERS=99 statement in your CONFIG.SYS will use 198K worth of disk buffers instead of 50K without Disk Manager (in addition to a few K for the driver itself). If you partition the disk into three partitions of 32 megs or less, then the driver doesn't have to fake DOS into larger sectors, saving you a lot of RAM for your disk buffers. Unless you have files larger than 32 megs, there isn't really any reason NOT to partition the disk into smaller chunks. You might also want to use BUFFERS=40 to BUFFERS=50 if you are currently using BUFFERS=99--it quite likely will speed up your disk accesses, as well as saving some more RAM. -- UUCP: {ucbvax,harvard}!cs.cmu.edu!ralf -=-=-=- Voice: (412) 268-3053 (school) ARPA: ralf@cs.cmu.edu BIT: ralf%cs.cmu.edu@CMUCCVMA FIDO: Ralf Brown 1:129/31 Disclaimer?

I have a 300MB SCSI disk and I was missing about 100K. The solution was to use less buffers. I had BUFFERS=30. With the cluster size at 4K, this added up. When I reduced buffers to 20, I got about 40K of memory back. I also asked them if it was possible to install this driver in higher memory; at this time it is not possible. Eric M.
