Anyone out there with an Adaptec 2940U2W? C'mon in please!

[GeoffS]

At boot up, after the card identifies itself, a listing of the hds it finds is generated. This lists the SCSI id, the drive identifier (ie. IBM 09Y), and a number at the end of the line (40.0, 20.0, 10.0, 8.0 are the ones I have seen). What is this number? Is the the throughput in mb/sec? If so, I am somewhat confused as I have 2 identical IBM drives on the wide 'channel' (not the U2W), that identify as 40.0 and 20.0 respectively. They are all that is on that 'channel'. The narrow 'channel' has a Toshiba 6201 CDROM that shows 10.0, and a Yamaha 4416 burner that shows 8.0. Does this number represent something other than throughput? I don't find any reference to it in the manual.

Thanks!

I have one here....and there is no number besides disk label...

Ill check this later this evening...

flash to the new bios and you'll get it. old bios is 2.00, new is 2.57 or 2.5 something

 

[GeoffS]

I have 2.57 I believe... so what is the number?

 

[Vegito]

That should be how fast your connected to.. I have some Atlas connected to the U2W LVD and it says 80 which is what it should be. Goto the BIOS and check if the number on that SCSI ID is set to 40 or 20, you might have 1 ID as 40 and the other as 20. Thats a maybe.. unless the two drive have different firmware - possible.

 

[GeoffS]

The two drives have the same firmware. Strange! When I get home, I'll take a look at the drives with the Adaptec SCSI tools and see it there is some configuration difference on the actual drive. As I recall, all the IDs are set to 80.

Thanks!

 

[GeoffS]

Hmmm...interesting... Using the EZ-SCSI 5 tools (SCSI Explorer to be exact), the drive that reports 40.0 supports 16 bit data transfer (Wide SCSI), but the drive that is reporting 20.0 does not. They are identical drives with the same firmware: IBM DGHS09Y Revision 03B0. Could this possible be a problem with the SCA => 68/50 pin adapter? These are not LVD drives and don't need any special adapter.

Thanks!

The transfer rate should be identical on both drives[if they are identical] then something is wrong.
The drive at the end of the chain should be set to zero, next at one, etc etc scsi id at 7.

You might try booting with only one hd hooked up[check transfer rate}, then swap hd and reboot and check again, may help you to narrow down which drive is not getting the right transfer rate
