Original Post:

Dear Sun Managers,

I just inherited this Sun IPC running SunOS 4.1.3
And this is the first time I saw this error message:

......
......
sd3 at esp0 target 0 lun 0
sd3: corrupt label - bad geometry
sd3: Label says 676305 blocks, Drive says 675484 blocks
sd3: Vendor 'MAXTOR', product '7345-SCSI', 675484 512 byte blocks
le0 at SBus slot 0 0xc00000 pri 5
cgthree0 at SBus slot 2 0x0 pri 7
bwtwo0 at SBus slot 3 0x0 pri 7
fd0 at obio 0xf7200000 pri 11
root on sd0a fstype 4.2
swap on sd0b fstype spec size 23004K
dump on sd0b fstype spec size 22992K

Is it a serious error message? Do I need to replace the disk? What cause
the label to get corrupted? I assume that I need to reformat, partition and
relabel the disk. Is it correct? Please help me.

Thanks, Aline...

Hi Aline,
I had this problem with a SUN0207 (Maxtor) drive I labeled it as a Maxtor
LXT-200S and have been using the drive witout any problems for the past
10 months.
I think my drive is faulty towards the end of the drive so formating it as
a smaller drive seems to fix the problem.
I would like to know why this works!!
Please summarize.
Hope this helps.

In list.sun-managers you write:

>Is it a serious error message?

Serious enough.

>Do I need to replace the disk?

Perhaps, if the problem reoccurs.

>What caused the label to get corrupted?

Perhaps labelling the disk with an incorrect format.dat entry.

>I assume that I need to reformat, partition and >relabel the disk. Is it correct? Please help me. Relabelling should be enough.

Yes and no. It means that the OS won't be able to use the Disk the Way it is.

> Do I need to replace the disk?

Maybe, but try reformatting first.

> What cause the label to get corrupted?

Most likely: Someone low-Level accessed the Disk inappropriately, over- writing the Label.
