Hi,

We have to phase out and decomission several Compaq/HP servers and
respective hard drives. I attempted to use a tool 'maxblast' (or something
like that) in the past, and I didn't get that one to work on multiple hard
disks with unconfigured RAID.

Two questions:

1)If I use the vendor tool to 'delete' an array and 'recreate' an array, is
the data on the hard drive wiped out? According to the message on the screen
it says that is the case. I am wondering if security wise, the data on the
hard drive has been destroyed for good and what it would take to recover it
in case someone with bad intentions manages to explore data from those hard
drives.

2)Imagine I run 'SmartStart CD' (it is just a vendor initialization software
from HP) and I run the option 'Erase System Partition'. That respective
option tells me that the whole data and system partition would be deleted
from the hard drive. Upon running the tool I noticed that the LED on the
hard drives flash very quickly and the message on the screen states that the
data has been erased. Since that happens so fast, I am wondering whether the
data has been wiped out? If I don't get an answer from people on this, I may
ask HP, however I am trying here to get an unbiased feedback.

Thanks much,

Marlon

Since I haven't ever used HP's proprietary utilities, I can't comment on
what they do. I would ask HP tech support. Instead, you may want to look
at Acronis Drive Cleaner. It has a ton of options. Check with the
Acronis site for this product regarding usage with RAID arrays.

No. Use a disk sanatizing software utility. A common utility is that from
Norton/Symantec
that comes with several suites and Ghost called GDisk.exe. You can actually set
switcgh
parameters to wipe each disk according to current DoD standards.

Otherwise use a deguasser if you don't go the software wiping route.

I have a deguasser here and I will use this one. That's quicker I think. The
only thing is that I understand that the deguasser would not only format,
but it would make the HD's useless, what is not a problem in my case anyway.

You are correct except the term "format" is specific to preparing a hard disk to
have a
structure an OS will use to read/write files. The act of degaussing will
destroy both the
High Level Format and the Low Level Format and can leave the disk unusable [NOTE:
manufacturer tools may be used to re-low level format the disk and subsequently
high level
format the disk]. However, degaussing will guarantee a sanatized disk with the
Bellevue
SchoolDistrict having no worries.
