RAID
data recovery
Redundant
Array of Independent (or Inexpensive) Disks is another concept to
store the data on two or more than two hard drives. Regardless of
the file systems used in the RAID configurations Promise data recovery
can recover data from it.
" RAID 0 : Without Fault Tolerance Striped Disk Array
" RAID 1 : Mirroring
" RAID 2 : ECC Hamming Code
" RAID 3 : Parity with parallel transfer
" RAID 4 : Shared Parity disk with Independent Data disks
" RAID 5 : Distributed parity blocks with Independent Data
disks
" RAID 6 : Two independent distributed parity schemes with
Independent Data disks
" RAID 7 : High Data Transfer Rates with Optimized Asynchrony
for High I/O Rates
" RAID 10 :High Performance combined with Very High Reliability
" RAID 53 : Data Transfer Performance & High I/O Rates
" RAID 0+1: High Data Transfer Performance
List of Raid Failures
o Lost of data due to the expansion & reconstruction of array.
o One or more hard drives down in RAID
o Accidental replacement of RAID Drives
o Applications those are unable to run or load RAID data
o Corrupt RAID files / data
o Array controller failure
o Corrupted partition & invalid volumes
o Failure of one or more hard drives.
o Registry configuration lost
o Damage due to fire and water
RAID
data recovery from Windows based platform :
In windows raid implementations can be software or hardware or both
mainly known as Hybrid. Furthermore, Raid0, Raid1, and Raid5 are
common raid structures used in Windows Os family.
RAID
data recovery from Macintosh based platform :
HFS, HFS+, and UFS are few file systems use in X-Serve G4/G5, and X-SAN
systems RAID configurations. These configurations can be Striped,
spanned volume, Mirrored or Parity based RAID .
RAID data recovery from LINUX based platform :
Promise
data recovery also recovers data from Linux based software RAID
(multi-disk and EVMS) Inboard, outboard DASD (Direct Access Storage
Device) boxes RAID, and disk controllers RAID.
RAID data recovery from UNIX based platform :
In
addition, Promise Data recovery not only accomplishes raid recovery
in Novell NetWare with Traditional and NSS file systems. But also
support raid recovery from Unix SCO Open Server, different flavors
of BSD, Solaris, HP-UX with 15+ file systems including UFS, VxFS,
JFS, FFS.
Note:
Please do not forget to give the numberings to the drives while
taking them out from any servers. If possible ship or bring all
the components originally used in the configuration of the Raid
structure which includes controller card, utility software and cables.
