RAID 0 capacity

[HAL9000]

Go to a DOS prompt and type DIR. How much free space do you have?

I have an old Compaq Proliant with a SCSI Disk Array that I have aquired for personal use. I have two 2.1 GB drives in the Array configured as Logical Drive 1 under RAID 0.
The configuration utility does list it as a 4.2 Gb logical drive.
When I launch Windows (95B) and check the properties of the drive it is only listed as 2.1 Gb.
Do I really have the full 4.2? When I copy files to it, both activity lights do light up together.
Is W95 just interpreting it incorrectly?
TIA

Hi F525,

Well being that win95b only supports only 2.1 gig (uses fat 16) partitions I wouldn't be sure, when you made the fdisk partition on the drives how much did it show up as? Both drives are working on the array because even though you might only have 2.1 gig, that partition is equally spread out on both drives...so both would always get read and written to. Try what Hal said and let us know. HTH

Win95B supports more than 2.1Gb, it's Win95a that has the restriction.

Thanks Hal....I thought only win95c support fat 32...therefore increasing partition over 2.1 gigs? Does the "b" version support FAT 32 as well? I must have my letter mixed up somewhere...thanks for clearing that up.

Win 95 and 95a are fat 16 only. 95B is "OSR2" with IE3 and 95C is 95B with better USB support and IE4.

glc got it, and there is a version D that I mentioned in another discussion that is pretty well 98 in a 95 wrapper.

Hi, thanks for your replies.
I'm going to have to look into this a little deeper. I exited W95 to DOS. I could only get a C: prompt which is my boot drive. The Array is the D: drive while I am in Win95. When I typed D: then enter, it said invalid drive. I think I need to make up a boot disk with the scsi drivers on it to access the D: array.

Your comments and what I just found out may indicate the problem. Because, when I had run FDISK before, I only saw the C: drive; NOT the D: drive (which is the array).

I'm thinking now that I need to make this boot disk to access it in DOS, then re-FDISK it again.

What do you think?

Thanks again.
Dwight

Exactly - if you need to access the array from a dos boot, you need to load SCSI drivers. I don't *think* anything is broken - why don't you try pulling one of the drives and see what happens in Windows? I would bet that 95 will still see it as a 2.1 gig drive no matter which one you pull - and when they are both there Windows is writing to both and reading from God knows what <g>

Is C drive IDE - SCSI (if SCSI is it a partition on the array)

In windows is the D drive fat32 or fat16

Have you run fdisk from a DOS window

> Is C drive IDE - SCSI (if SCSI is it a partition on the array)
Answer: The C drive is also SCSI. It is on a seperate SCSI bus which resides on the mother board. I gave it boot priority in the "CMOS". (It is not a partition on the array. The array is controlled by an interface card. A 50 pin ribbon cable goes from the interface card to the 2 drives that are on the array.)

>In windows is the D drive fat32 or fat16?
Answer: The D drive does FAT 32 when I check properties on it. (C: drive also).

>Have you run fdisk from a DOS window?
Answer: No, I booted to a startup disk when I ran the FDISK and couldn't see the D: drive. At your suggestion, I also tried it from a DOS window in windows. Still can't see the D: drive; just the C: drive.

Tnx, Dwight

As mentioned above, I am hunting for a DOS driver for the array to put on the startup disk.

Follow up question: But when I do find the driver, do I just put a line in the config.sys file to use it?
i.e. something like device=array.sys (with a copy of array.sys on the floppy.)

TIA, Dwight
