Mirror Ü
ßßßßßßß
Records information about one or more disks; the unformat and undelete
commands can use this information to restore a reformatted disk or to
recover deleted files.
Syntax: MIRROR [drive:[...]] [/1] [/tdrive[-entries][...]
MIRROR [/u]
MIRROR [/partn]
drive: Specifies the drive for which you want Mirror to save information.
/1 Retains only the latest disk. If you do not specify /1, Mirror
makes a backup copy of the existing disk-information file before
recording the current information.
/tdrive[-entries]
Loads a terminate-stay-resident (TSR) deletion-tracking program
that records information used by undelete to recover files. The
required drive parameter specifies the drive for which you want
Mirror to save information about deleted files. The optional
entries parameter, which must be a value from 1 through 999,
specifies the maximum number of entires in the deletion-tracking
file (PCTRACKR.DEL). The default for entries depends upon the
type of disk being tracked. The following list shows each disk
size, its default number of entries, and its corresponding file
size:
Disk size Entries File size
360K 25 5K
720K 50 9K
1.2MB 75 14K
1.44MB 75 14K
20MB 101 18K
32MB 202 36K
> 32MB 303 55K
CAUTION Do not use deletion tracking for any drive that has been
redirected with join or subst. If you intend to use assign,
you must do so before using Mirror to install deletion tracking.
/u Unloads the deletion-tracking program from memory. You cannot
unload the tracking program if you loaded any other memory-
resident programs after it.
/partn Saves system information about how a hard disk is partitioned.
and saves it in a file on floppy disk. Unformat can use this file
later to rebuild disk partitions.
