|

help
|
|
On DiskOnChip devices shipped with the INFTL filesystem (Millennium
|
|
and 2000 TSOP/Alon), Linux reserves some space at the end of the
|
|
device for the Bad Block Table (BBT). If you have existing INFTL
|
|
data on your device (created by non-Linux tools such as M-Systems'
|
|
DOS drivers), your data might overlap the area Linux wants to use for
|
|
the BBT. If this is a concern for you, leave this option disabled and
|
|
Linux will not write BBT data into this area.
|
|
The downside of leaving this option disabled is that if bad blocks
|
|
are detected by Linux, they will not be recorded in the BBT, which
|
|
could cause future problems.
|
|
Once you enable this option, new filesystems (INFTL or others, created
|
|
in Linux or other operating systems) will not use the reserved area.
|
|
The only reason not to enable this option is to prevent damage to
|
|
preexisting filesystems.
|
|
Even if you leave this disabled, you can enable BBT writes at module
|
|
load time (assuming you build diskonchip as a module) with the module
|
|
parameter "inftl_bbt_write=1".
