Kupi³em dysk twardy.Seagate 2,5GB ST 52520A. Przez kilka dni chodzi³
normalnie Windows itd. Pó¼niej
gdy chcia³em go przenie¶æ do drugiego komputera i ustawi³em jako sleave,
zaczê³y siê k³opoty. Wszystkie pliki siê pokaszani³y tzn.krzaczki zamiast
nazw. Prze³o¿y³em go do drugiego komputera, zdj±³em partycjê, za³o¿y³em
now±, sformatowa³em ale po resecie albo partycji nie ma albo po przegraniu
na ni± wszystko zmienia strukturê i nie mo¿na uruchomiæ plików. Graficzne s±
poprzestawiane itd.
Próbowa³em niskopoziomowego formatowania, od¶wie¿ania bootsektora mks'm,
dyskietk± od seagata i po dwóch dniach uda³o mi siê go uruchomiæ ale tylko
na trzy dni. Pó¼niej bawi³em siê w Winie i po resecie dalej to samo. Teraz
ju¿ kolejny dzieñ próbujê co¶ zrobiæ i nic. Próbujê formatowaæ
niskopoziomowo ale nic to nie daje. Dziwne jest to, ¿e gdy uda³o mi siê go
uruchomiæ to chodzi³ na dziwnych ustawieniach.
4970 cyl, 16heads, 63 sect i auto (które pó¼niej w biosie tzn. w ramce
wykrywa³ jako LBA,
a takie ustawienia s± dla NORMAL
LBA powinno byc:
621 cyl, 128 heads, 63 sect ale na takich ustawieniach te¿ nie chodzi.
Nie mam pojêcia co zrobic i jak to ustawic. Dziwne jest, ¿e po sformatowaniu
niskopoziomowym dalej na dysku jest wszystko.
Jeszcze mam pytanie o co chodzi z Alternate Capacity?
Tutaj kawa³ek ze specyfikacji dysku.
Badzo proszê o pomoc i ewentualne podpowiedzi co mogê z tym jeszzcze zrobic

Alternate Capacity jumper sets the default cylinder translation
to 4092 to solve issues with certain BIOS that only auto-detect.
Total available sectors are still at full capacity as reported via
Identify Drive data words 52 - 61. Third party partitioning software
may be needed to achieve full capacity if this option jumper is used.

TYPE AVAILABLE. (see below)
Possible translations:
This translation is generally acceptable, as
is, for non-DOS operating systems:
4970 cyl, 16 heads, 63 sectors = 2,564,997,120
DOS operating systems may require a translation
that uses larger values for the CMOS head
parameter which lowers cylinders below 1024:
621 cyl, 128 heads, 63 sectors = 2,563,964,928
Other FULL-CAPACITY solutions for DOS operating
systems include third-party drive preparation
software, system BIOS which supports LBA mode
or bios driven host adapters. Otherwise,
capacity may be limited to:
1024 cyl, 16 heads, 63 sectors = 528,482,304
Some systems BIOS have capacity limitations.
Types that have been identified are:
a 2.113GB or 4095 cylinder limitation
and, if exceeded, may cause the system to fail or lock up during POST
with auto-detect options set in the CMOS.
Note: A "custom" or "user-defined" CMOS drivetype may ask for a
numerical value for the Write Precompensation cylinder and for the
Landing Zone cylinder. A basic rule-of-thumb for drive models that do
not require the old Write Precomp technique or a Landing Zone because
they are Auto-Parking is to add 1 to the cylinder value being used. As
an example: If cylinders equaled 820, then both Write Precomp and
Landing Zone would be entered as 821. Some BIOS will convert this to
65535 or -1, which are functionally equivalent to "none (not used)".
PHYSICAL/LOGICAL equivalent to NATIVE/TRANSLATION
ZBR = Zone Bit Recording = Variable sectors per track
Already low-level formatted at the factory.
Since a User-definable or Custom translation geometry may be used, it
is imperative that the values be written down and kept with your
permanent records for retrieval in the event of CMOS battery failure.
