Hard disk failure on Netserver E60

[madhu_11]

I am facing frequent hdd failure on my E60 server. My configuration is p3 500/128mb/3*9.1 gb and my os is netware 4.2.

My first hdd is sys volume and my second and third hdd's are mirrored.My server reported a hanging pbm. I restarted the server,but my volumes on second and third hdd's are not mounting. All the hdd's are detecting on netware, but if i am going to MONITOR--DISK INFORMATION-and then PARTICULAR HDD-it is showing as inactive. If I am trying to activate it,no error is reporting and it is in inactive state only. If we go to INSTALL--DISK INFORMATION AND THEN PARTICULLAR HDD, it is giving error that PATITION TABLE NOT FOUND. The same pbm for both the HDD's.

If we reboot the server and go to ADAPTEC 7895 BIOS OPTIONS and trying to varify the media , it reports the following error

Target scsi id-------------4
Scsi cdb sent--------------03000000070000200
Host adapter stattus--No host adapter error
Sence code 02h--------not ready
Sence code-------------40h
Sence code qualifier----80h

The same error is reporting for both the HDD's.

The same error is reporting even if I am trying to format the hdd.

I changed the SCSI HOST ADAPTER and SCSI CABLE also. The first hdd is detecting and wkg very fine in place of old hdd's.

My hdd model is DNES-309170 (68P U2W SCSI HDD)
P/N is 25L2131
I changed the HDD's and now it is wkg fine.

Now I am in a mess. My entire data was lost even if I am having Mirroring.

Is there is any way to get my data.
