invalid. When such record is deleted, the user data space gets
supplemented
with a certain number of extra
sectors, which can be hidden in the translator automatically or manually.
♦
Non Resident G-List clearing. In many cases that list of defect records supplementing the translator is
empty. However, an error during translator recalculation or other corruptions of service information may
cause in it records with a flag other than 0, which will prevent the translator recalculation procedure from
clearing the list and thus include that invalid information in the translation process. The feature allows you
to force clearing of Non Resident G-List, after which you can again initiate automatic restoration in the
'First start' mode
.
♦
Non Resident G-List editing. Since the list can contain both correct and invalid records, the utility allows
you to work with them selectively in manual mode.
Attention!
Records in Non Resident G-List may be described both as single sectors or chains thereof. A chain may
span across several tracks. Therefore, a backup copy of Non Resident G-List should be saved prior to any
manipulations with it. At the same time, clearing it before restoration cannot be recommended with certainty in all cases
as it may result in a time-consuming process hiding thousands of sectors of a defective track.
As tracks hidden in Non Resident G-List are not uncommon, we shall describe further the method for their
identification and quick hiding. If automatic restoration stops because the maximum length of a hidden chain is
reached, you can suppose one of two scenarios - an "extra" defect and a long, often track-sized chain. Let us examine
the second case. Suppose that the translator has diverged at LBA = 10 000 000. For further diagnostics we need to
convert the number in hexadecimal notation. LBA = 10 000 000 = 0x00989680. First, we identify physical location of
the LBA. To do that, use the terminal command A>
F
aaaa,bbbb,,10, i.e. command
F
on level A> with the aaaa and
bbbb parameters defining the LBA
. Here bbbb represents the last 4 characters of the LBA number in hexadecimal
notation, aaaa – the next 4 characters. The 0x prefix is omitted. If an LBA in hexadecimal notation is represented with
less than 4 characters, they are used in the bbbb position as they are, with 0 substituted in the "a" position. Thus the
number 0x00989680 is split into two groups – 98 and 9680; therefore, the necessary command is as follows:
A>
F98,9680,,10

Alternatively, you can recalculate the translator based on P-List, delete the FoundForks.lba file and start the
automatic procedure with LBA = 0.

Parameter 10 defines the number of LBA for translation in hexadecimal notation. In this case, 10 means that 0x10 =
16 sectors will be translated.
