Spinning Brown Donuts: Why Storage Still CountsSparkhound Inc.
Storage, next to server hardware, is pretty commoditized and probably the least exciting thing in your datacenter. However, not properly assessing your storage needs and requirements can be the difference between a great app or resume generating event. This session will cover topics such as: Why you may not need all flash, SAN is not just NAS spelled backwards, leveraging cloud storage, why RAID is not a sound backup solution, and cutting through the marketing to make sense of it all.
Floppy disks, CDs, DVDs, tape drives, flash memory, and memory cards are described as common data storage devices. Floppy disks were widely used in the late 20th century but have been largely replaced by methods with greater storage capacities like USB flash drives, external hard drives, and cloud storage. CDs and DVDs introduced rewritable formats like CD-RW and DVD-RW that allowed erasing and rewriting data multiple times compared to write-once formats.

RAID (Redundant Array of Independent Disks) technology was invented in 1987 to improve data storage performance and reliability. It combines multiple disk drive components into one or more logical units. There are different RAID levels that determine how disk arrays are used, with RAID 0 through RAID 6 being the standard levels. RAID levels use techniques like striping, mirroring, and parity to provide features like fault tolerance, high throughput, and data redundancy. Each level has advantages and disadvantages for performance, reliability, and capacity.
Hard disks are organized into tracks and sectors through low-level formatting. Partitions divide the hard disk into separate areas that function as individual drives. High-level formatting defines the file allocation table (FAT) for each partition to locate files. Common storage devices include IDE/EIDE and SCSI hard drives, floppy disks, and CD-ROMs. RAID configurations provide fault tolerance through disk redundancy and parity.
The document discusses various types of storage devices and media.

Webinar: Designing a schema for a Data WarehouseFederico Razzoli
Are you new to data warehouses (DWH)? Do you need to check whether your data warehouse follows the best practices for a good design? In both cases, this webinar is for you.
A data warehouse is a central relational database that contains all measurements about a business or an organisation. This data comes from a variety of heterogeneous data sources, which includes databases of any type that back the applications used by the company, data files exported by some applications, or APIs provided by internal or external services.
But designing a data warehouse correctly is a hard task, which requires gathering information about the business processes that need to be analysed in the first place. These processes must be translated into so-called star schemas, which means, denormalised databases where each table represents a dimension or facts.
We will discuss these topics:
- How to gather information about a business;
- Understanding dictionaries and how to identify business entities;
- Dimensions and facts;
- Setting a table granularity;
- Types of facts;
- Types of dimensions;
- Snowflakes and how to avoid them;
- Expanding existing dimensions and facts.

Summary: What processwritessectormarkingstoa hard drive? Thisarticle will analyze the 4
optionsforthe answerindetail andfinallygive youthe rightoption.Learnmore knowledgeabout
diskpartitioningandformattingon MiniTool partitioneditorwebsite.
The Background
There isa questionthatispopularamongthe studywebsiteslike Quizlet,Course Hero,StudyBlue,
BrainScape,andso on. The questionis“whatprocesswritessectormarkingstoa harddrive?”,and
there are four optionsfor the answer:
A. Partitioning
B. Low-level formatting
C. High-level formatting
D. Sectorprovisioning
2. Alt=Which ProcessWritesSectorMarkings to A Hard Drive?
Before tellingyouthe answer, thoughmanyof youmay alreadyknow the result, let’sdive deepto
the relatedknowledge of thisquestion.
About the Question: What Process Writes Sector Markings to a Hard Drive?
There are still some people,especiallypeoplewhoknow littleaboutcomputertechnology,who
can’t evenunderstandwhatthe questionmeans.Tofigure outwhatthe questionrefersto,let’sfirst
of all learnsomethingabout“sectormarkings”.
Sectormarkingsmeanthe marks that divide aharddrive intosectors.Then,let’sgofurtherto
discusssomethingaboutharddisksectorsandtracks.
Olderdisksadopta straightforwardmethodologytowrite tracksand sectors onthemselves.They
have 26 or 17 sectorsoneach track overthe whole diskplate.The trackthatlocateson the centerof
the drive determinesthe numberof bytesthatatrack can contain,andit forcesall othertracks
followingthe same restriction.Therefore,the largertrackslocatednearthe outside of the plate
have the same numberof sectors andbytesas the smallertracksnear the centerof the platter.This
methodology makesdiskformattinganddataaccessingsimpler;yet,itwastes alarge amountof disk
space.
3. Alt=Old Drive Track SectorArrangement
Modernhard drivesabandonthatmethodologyandthe numberof sectorspertrack isn’tthe same
overthe entire plate.Theyuse anewformattingsystemcalledzone bitrecording.Accordingtothe
newsystem,tracksnearthe centerof the platterhave fewersectorsof eachtrack than that of tracks
nearthe outside.
4. Alt=Modern DiskFormatting
Each track onan IDE diskisdesignedtohave the mostpropernumberof sectorsappropriate tothe
size of the track. To make thisarrangementpossible,there is afact that hardlychanges– Every
sectoron the hard diskstill has512 bytes.Withoutthisconsistency,there hastobe a much more
complex interfaceforthe operatingsystem(OS) toreachthe datasavedon the drive.
Since eachtrack of a moderndiskhas a differentnumberof sectors,the OScan’tcommunicate with
the diskcontroller(firmware) relyingonsectorandtrack coordinatesasitdoeswitholderharddisks
or floppydrives. So,forthe currentdrive formattingsystem,the OSandBIOS make use of a simple
sequentialnumberingsystemknownas logical blockaddressing(LBA) toaddressall the sectorson
the hard drive withoutregardtowhere those sectorsare located.
About the Options
There are all 4 optionsforthe question of whatprocess writessector markings to a hard drive.To
figure outwhichone isthe answer,youshouldknow whatare the fouroptionsare about.
Partitioning
Partitioninghere meansdiskpartitioningthatalsoknownasdiskslicing.Diskpartitioningrefersto
create one or more regionsonsecondarystorage of computerstorage.Those regionsare called
partitions,whichcanbe managedseparately.
Diskpartitioningisthe firstthingyoushoulddotoa new harddrive before creatingany file system
to the disk. The drive savesthe partitions’locationsandsizesinformationinasectioncalledpartition

(e.g.diskC,D, E, etc.) actually occupiesonlypartof the actual hard drive.

Disk PartitioningAdvantages
Systemadministratorsrelyonaprogram, partitioneditor,tocreate,resize (extendorshrink),delete
as well asmanipulate the partitions.Diskpartitioningpermitsthe usage of differentfilesystemsto
be installedfordifferentkindsof files.Toseparate userdatafromsystemfilescanavoidsystem
partitionfrom lowdiskspace problems.Also,diskpartitioningisable toease backupprocessesby
sortingdifferentkindsof dataintodifferentpartitions.
Disk PartitioningDisadvantages
One disadvantage of partitioningis thatitcan be difficulttocreate a partitionwithapropersize.
Usually,computerusersencounteraproblemthatone partitionisnearlyfull (usuallyasystem
partition) whileanotherone isalmostempty.
Fortunately,there isthird-partydiskpartitioningsoftwarethatcan solve thatproblemby resizing
partitions.Thatis,to reallocate the free space fromthe emptypartitiontothe full partition.
Therefore,to make a balance of available storage space amongall existingpartitionsaswell asthe
unallocatedspace.
Disk Formatting
Diskformattingisa processof preparingadigital datastorage device,like aharddiskdrive (HDD),
solid-state drive (SSD),floppydisk,USBflashdrive,etc.,forinitialusage.Insome situations,the
formattingprocessmaycreate one or more new file systems.
5. The firststepof diskformattingisoftenreferredtoas“low-level formatting”,whichperformsthe
basicmediumpreparation.The secondstepforformattingadiskispartitioningthatwill enablethe
visibilityof the storage devicetothe OS.Finally,the thirdstepof the formattingprocess,usually
called“high-level formatting”,will create anew file systemtothe storage device.
In some OSes,all orsome of those three stepscanbe combinedorrepeatedatdifferentlevels.So,
the term “format”meansa task withinwhichanew diskmediumiscompletelyreadyforsavingfiles.
Besides,some formattingallowsdistinguishingbetweena quickformattingand full formatting,with
the laterwill erase all existingdata.
Generally,diskformattingbydefaultwillleavemostif notall existingdataonthe hard drive,though
those data are invisibleandseemlost.Those “lost”data,some of mostof themmightbe recovered
by special toolsorprivileged.Yet,the special toolscanalsoremove databysimply overwritingall
filestogetherwithfree space.

Low-level Formatting(LLF)
LLF marks the surface of the driveswithsectormarkersindicatingthe startof a recordingblockand
otherinformationsuchasblockCRC to be usedby the diskcontrollertoreadand write data.Low-
level formattingisintendedtobe a permanentfoundationof the diskandisoftencompletedbythe
manufacturers.
Tip: Until now,you get theanswerfor“what process writes sector markingsto a harddrive?”. That
is low-level formatting.Yet,wewill still continuewith ourarticle.
Hard diskmanufacturerswill use autilityprogramtoperformlow-level formattings,suchasthe OS,
systemBIOS,or utilitysoftware.
Since sectorand track markingswill eventuallyfade,aharddiskwill eventuallyreportmanybad
sectorerrors.In the past, the solutionisto back up all diskdata andperformlow-levelformatting
againto get a newstart. If a harddrive isperiodicallylow-level formatted,itcanlastdecades.
Nowadays,since the drivesare low-level formattedinthe factory,theirsectorandtrack markings
are expectedtolastforthe lifespanof the disk.Thus,moderndrivesare consideredmore disposable
than olderdrives.Whensector&track markingsfade,diskswill warnof “badsectoror sector not
found”error or become unavailable.Then,youshouldtake outwhateverdatayoucan from the disk,
thenthrowit into a garbage can and buya new hard disk.

Manage Hard Drives Without Writing Sector Markings to Them
Justas mentionedinthe above,onlylow-levelformattingisthe answertothe question which
process writessector markings to a hard drive.On the contrary, itmeansthat partitioning,high-
level formattingandsectorprovisioningdon’twrite sectormarkingsto harddisks.
And,the low-level diskformattingisnow performedbydiskmanufacturersandcommonusersare
not recommendedtoconductit.Then,how aboutdiskpartitioningand high-level formatting,can
