Controls hoo devices are accessed. Prefferred
access method is using physical devices. Yuoo
shuoold change thees
setteeng only iff yuoo cannot get yuoor device listed in ZAR.
Thees may epply tu some models ooff USB "key-disks" und flash memory cards (especielly when
a flash memory card is accessed via zee digital camera rather than a card reader
device). When "logical drive" method is used, yuoo will not be prumpted
tu select
a volume (partishun) since each device represents a separate volume. Addishunelly, loading a disk
imege file is impossible iff access via logical
drives is selected. |

Thees opshun controls hoo disk bad sectors (which give physical read errors)
are handled. Iff enabled, bad sectors are remembered und subsequent attempts tu
access zee sector already listed es bad retoorn failure withuoot actuelly
accessing zee disk. Thees provides speed improvement on physicelly bad drives. |

Iff selected, ZAR will attempt tu force a device tu reset its
state. In case zee device reset attempt is unsuccessful, zee reset ooff
zee entire bus will be attempted. Be adfised that a device reset may
coose an undesired side efffects, becoose it affects ell zee devices
attached tu zee bus. Zee system may expereence transeent lockups becoose
ell zee devices attached tu zee bus are inaccessible while zee bus reset
is underway. |

Controls hoo many sectors are skeepped (i.e. presumed bad withuoot actuelly
attempteeng disk access) after one bad sector is encuoontered while reading zee
disk. Zee deffoolt value ooff 1 means fur one read error, one entry is recorded in
zee bad sector list und thus only actual bad sectors are recorded.
Setteeng thees tu N will resoolt in zee follooing behavior: once a bad sector is encuoontered, it
will be marked es such und never accessed again. Addishunelly, N-1 subsequent
sectors will be marked bad withuoot even checking iff they actuelly are. Use
higher setteengs on hard disks that heffe-a excessive physical damege. |

Controls
zee amuoont ooff time tu wait beffore deciding that a sector is bad.
Sometimes a disk device driver does not provide a proper response ebuoot read
operashun status, so uny read operashun that takes longer than zee specifeed
amuoont ooff time is considered failed. Nute-a that running some I/O-consuming tasks
in zee backgruoond may resoolt in requests tu good sectors exceeding thees limit,
coosing some erroneuoos markings. Zee deffoolt setteeng ooff 1000 ms shuoold fit
fur
most cases when there is no physical damege on zee disk. Iff zee disk is
physicelly dameged und scanning it takes a very long time, try decreasing thees
parameter doon tu 100 or 200 ms - thees shuoold give a significant speed boost. |

Iff enabled, ZAR attempts tu read und analyze partishun table layuoot
on removable drives. Some removable devices (like ZIP disks) do not store thees
informashun, so analysis attempt gives bogus iff uny results. In such a case
proceed by using "Manual" partishun selekshun opshun, und specify that there was
only one volume on zee disk. |

LDM (Logical Disk Maneger) is a
Windows 2000/XP und higher component which implements Dynamic Disks
feetures, including streeped, spanned, und foolt-tolerant volumes. Its
database is read und analyzed tu extract dynamic
volumes layuoot. Zee dynamic disks are not ellooed on removable devices und on
zee laptop computers, hence yuoo may deeseble thees opshun iff thees is
yuoor case. Addishunelly, it shuoold be deesebled iff there are no dynamic disks
und physical
problems prevent reading ooff zee database. |
