Romulus hangs...
July 11th, 2005, 10:40
Hi,
does anyone have an idea what to do when a romulus doesn't get ready after power up?
I started in SM, loaded a loader, but the SA is not readable afterwards.
it is a 4D040H2220511, KMDE, B9FDB.
BTW everything sounds OK, it just doesn't get ready.
thanx for any help.

Hi Pepe,
Did you try with other PCB?
I had one Rigel 40GB with somekind defect in PCB that do something similar to yours. It start the drive but drive can't do full calibrate and stop at the end of calibration process.And can't read SA even with right LDR) Afterwards I found that PCB(bad one) chnage 2-3 bits in ROM

Hi pepe,
ldr in Safe Mode - BSY - wait, wait, wait up to 20 mins.
Evfen if not BSY - wait, wait.......
only then select Standard Mode.
Then hopefully you can read KS and use ldr to suit
and maybe wait again.

Thanx all!
Of course I changed the PCB. Same situation
I will try to wait a little

Hi,
there is some evolution
I tried to load the loaders I have with other DSP utilities (athena, proxima), and they loaded perfectly, so there must be some bugs in the Romulus utility.
After loading I could read and correct modules in the Romulus utility (G list had read error and DNCS had ID error).
after that the drive initialized OK, no hanging, detected correctly but it seems that it cannot read from head 1 (UNC).
I found that the RCT module contained all zeroes, but despite of this it could read from Head 0 correctly.
I found that in module 02BA0080.rpm there is an RCT-like portion at offset 0x8400. So I copied it into the RCT module, corrected the header and the checksum, wrote it back to the SA.
But unfortunately nothing changed, no data from Head 1.
any ideas?
thanx,
pepe

Hi Pepe,
I just comapre RCT 21h with 02BA0080.rpm(0x8400) taken from working drive, and they does not seem to be identical. But you can rewrite this module from working drive anyway...
Could it be possible 93h& 78h to contain invalid data?

Hi,
thanx for your attention
meanwhile i came to the same conclusion regarding RCT and 2BA000A.rpm.
I will check 93 and 78.

Hi, $amo,
Could U tell me what is the purpose of mod 93?
thanx

Hi,
I tried many things like copy modules 1f, 78, 93 from a working drive, but nothing good happened, sometimes I got clicks when tried to read.
I don't think that Head 1 (3) is defective, because I could read the SA from it (though it contained empty modules), and after writing correct modules to it, FW structure test showed it OK.
So I think there must be something really bad with adaptives.
any ideas?
