How to format HP C2490A

Dilandau — Wed, 21 Jul 2010 09:19:14 GMT

I have acquired 2 HP C2490A.

I have a pci to scsi adapter Adaptec AVA 2904 which I have use with other SCSI 50 Pin old drives without problems.

I am trying to access the drive. The drive does not appear under Disk Management console on windows XP so I am not able to format it on Windows XP.

The disk does appear in Disk Management under Windows 7 (it was very surprising). But when trying to format it on windows 7 it gives I/O error: 0x8007045D. The same happened if I try to do it like a new installation.

I would think that the disk is wrong but happens exactly the same in both HP C2490A I have.

Do you think both drives are faulty? Do I need another adaptec pci card to try? What other tests I can try to make it work?

What you want to do with this old and sloooow stuff?

IIRC this is a 2GB single ended SCSI drive, so you need to use scsi ID between 0 and 6 and a single ended terminator.

Here is where I got the jumper settings

http://stason.org/TULARC/pc/hard-drives-hdd/hewlett-packard/HP-C2490A-002-2100MB-3-5-HH-SCSI2-DIFF.html

I am configuring it with parity and "Drive will spin up automatically at Power-On".

I don't see any jumper for single ended configuration.
I have tried with different SCSI Ids from 0 to 6 with same result.
Hardware is recognized by Windows 7 Management console but no other operative system ( neither Ubuntu, nor Norton Ghost, nor Windows XP)
And none of them is able to format it.

I am in need of using this hard drive as I have to fix a very old system witch make use of a SCSI 50 pin 213 MB storage size.

How about the terminator? Is it installed?

I have had other SCSI 50 pin in my hands but I have to say I am not an expert at all.
What I saw in other models is that there was always a pin to shortcut for single ended function... unfortunatelly not in this one.

Anyway, I recognize there should be a terminator for SCSI bus but I dont know how is it or where to put it.
To be honest I have not worry of it with previous hard drives I have tried which worked.

Here there is a picture of this hard drive without any pin. When I connected it, it had only the parity and ID=1 jumpers.

After checking my PCI to SCSI adapter (Adaptec AVA 2904) I see this spec:

"
Auto termination feature will enable or disable onboard termination automatically
"

So I suppose this is why I did not have problems with other drives. I also suppose that termination is installed.

Auto termination means the controller terminates an open connector. If devices (disks) are installed, the controller cannot (!) terminate this end of the bus.

You need a terminator behind the disks!

Without you get what you have, sometimes it looks like working, sometimes not, sometimes never.

Well.
I have installed a terminator. Actually the drive does have 2 pins for termination purposes:

"

15 Terminator Enable
--------------------
Front Pin: GND; Rear Pin: Terminator Enable

15 OPEN On-board active terminators disabled. Terminators not
connected to SCSI connector
15 CLOSED On-board active terminators enabled and connected to SCSI
bus. TermPwr source determined by placement of Terminator
Power pinset jumper.

16 Terminator Power
-------------------
Front Pin: SCSI pin 26; Rear Pin: TermPwr

16 OPEN TermPwr for on-board terminators provided by the drive
only. Drive TermPwr is not connected to SCSI connector pin
26.
16 CLOSED TermPwr for on-board terminators provided by the drive, and
drive TermPwr is connected to SCSI connector pin 26.

"

I have use both, so now I have: parity, ID=1, Power On and both terminations with jumper "CLOSED"

Still same results, I/O error when trying to format it
