Display of attached partitionable media, disk geometry and partition maps
This will display an overview of the partitionable media in table form, plus extensive geometry and size information for each disk. For each disk a pseudo-graphical map will be shown, with each partition or freespace area sized and colored according to its real size and type of filesystem being used. Some key information for each area will be shown inside each partition or freespace area displayed. Note that a 'disk' can be any partionable media supported by DFSee, like physical disks, virtual-disks, images and others ... - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Press <F1> again for more help; Some options may require switching to 'Expert mode'
Display and optionaly set a new geometry to be used for the selected disk
From menu: selects a disk, then starts a standard geometry dialog. The geometry dialog shows, and lets you set, the used geometry for the currently selected object, usually a disk. The geometry and size values for the current object are shown, and a custom or one of several pre-defined geometries can be selected and set: (*) Custom geometry, values: Specify CHS values manually ( ) Reset to system geometry Visible if L-Geo set differently ( ) Classic desktop/3.5" 255/63 OS/2 limit 502 GB \ for other OSes ( ) Classic laptops/2.5" 240/63 OS/2 limit 472 GB > no real limit ( ) Std SSD/4Kb-sectors 64/32 OS/2 limit 64 GB / ( ) Big SSD/4Kb-sectors 255/240 OS/2 limit 1912 GB \ for other OSes ( ) Huge rotating disk 255/127 OS/2 limit 1012 GB > no limits, but ( ) Huge rotating disk 255/255 OS/2 limit 2032 GB / not recommended The Big SSD has 240 sectors/track (120 KiB) to be a multiple of the most used read/write page sizes in SSD disks, for best alignment/performance. Note that setting a geometry for a disk is NOT modifying the disk!

Search partition-tables, LVM or FS-superblocks on cylinder boundaries (FAST)
This submenu has several selections that will find partition related sectors on the current disk using the 'bsfind' command. You can search for partition-tables (MBR/EBR/bootsector) plus LVM, or filesystem-specific superblock sectors, or a combination. The search is quite fast because it searches on cylinder boundaries where 99.99% of those type of sectors will be located anyway. This method of searching can be more than 200 times faster than simply searching every sector on the disk ... - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Press <F1> again for more help; Some options may require switching to 'Expert mode'

Change type for a partition from a list or custom value (NO FS CONVERSION!)
A partition can be selected here for which the PARTITION-TYPE can be changed to a predefined value from a list, or to a custom value specified as a hexadecimal number. The type usually represents the type of filesystem that is used for the partition, although some types are used for more than one FS like 0x07 = HPFS, JFS, NTFS or any other 'Installable File System' (IFS) and 0x83 for any native Linux filesystem like EXT2, EXT3 or EXT4 The most used values are predefined and selectable from a list with a short description, and a full line of extra description in the statusline at the bottom of the screen. To change the type of an extended container (05 / 0f), use the 'fixext' command, or menu 'Fix EXT container type' instead. NOTE: Changing the PARTITION TYPE does NOT change the CONTENTS of the partition in ANY way, it merely changes the type byte in the partition table, nothing else. To change the contents, from one filesystem to another one, you need specific filesystem-conversion programs, like the CONVERT.EXE tool on Windows-XP that converts FAT32 to NTFS, or you need to BACKUP the contents, re-FORMAT the partition with the new filesystem, and then RESTORE the contents. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Press <F1> again for more help; Some options may require switching to 'Expert mode'

You can specify which type of sectors are to be restored: r = MBR sectors e = EBR sectors G = GPT headers g = GPT entries l = LVM info, DLAT s = LVM sig, BBR b = Partition boot sectors If you specify just a BASE name for the file (without an extension), ALL files with that basename will be restored to the matching disks. (You can manually erase the extension in the Dialog filename field). This is a very quick restore of your partitioning scheme after damage from virii, FDISK errors or other disasters. The .PDx files can be created by running the DFSDISK or DFSTART procedures too, since these use the same 'PSAVE' command'. Be aware that the partition-scheme will be restored EXACTLY to the state it was when the backup .PDx file was created, so any changes to the partitioning, or even a FORMAT of a disk after creation of the .PDx file, will be lost You can also selectively restore individual sectors by using the command 'PRESTORE' from the DFSee commandline.

Convert an MBR-style disk to an EMPTY GPT one: NEWMBR, create GPT guard part
Convert an MBR-style disk to an EMPTY GPT one This is a 'NEWMBR -c' command, removing the MBR partitions, followed by a 'CR gpt' that will create a GPT guard partition spanning the whole disk, effectively making this a GPT disk. It WILL automatically recover any GPT partitions still defined in either the primary-GPT header+tables directly after the MBR or the alternate-GPT ones at the end of disk, when present (this would recover from an accidental 'newmbr' on the disk) Any new GPT partition can then be created using 'CR gpt ....' style commands, or the 'Create new partition' menu item. The operation is NOT directly recoverable, since the primary MBR table is zeroed. However, using the DFSee DFSDISK procedure it may be possible to recover the MBR-style partitions with some additional effort. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Press <F1> again for more help; Some options may require switching to 'Expert mode'

Add default LVM-information to the selected disk(s), making it LVM-enabled
This will create default LVM-information for all partitions on the selected disk(s) that do not have any LVM-info yet. This includes a default name for the whole disk. The functionality is similar to the standard IBM-utility 'VCU' or 'Volume Conversion Utility' that is typically used on first-time installs of any LVM-aware IBM operating system. The VCU utility however is known to create severe disk-problems when the disk-drivers in use are not the correct ones. The 'VCU' command in DFSee has not caused such problems so far and is considered a safer way of converting a non-LVM system into an LVM-aware one in a single step. When the disk already contains LVM-information, the diskname will stay the same, but most partition and volume-names will be changed to the default ones generated by DFSee, any assigned drive-letters may get lost and need to be re-assigned (depending on current OS). The driveletters recognized by the DFSee program executing 'VCU' will be the ones that are assigned in the created LVM-information. Typically, a 'VCU' action will be followed by interactive or batch LVM operations to fine-tune the names and assign driveletters. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Press <F1> again for more help; Some options may require switching to 'Expert mode'

Set default selection for the IBM Bootmanager menu, including 'Last booted'
This will set the default item for the IBM Bootmanager to be started after the timeout period has expired. The default can either be one of the available partitions on the Bootmanager menu, or it can be the special value: Last-booted or BM-default This selection will cause the default to be whatever the LAST booted partition was on the previous Bootmanager run. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Press <F1> again for more help; Some options may require switching to 'Expert mode'
Set timeout in seconds before the IBM Bootmanager default choice is made
This will set the time in seconds before the Bootmanager will start the default selection (timeout value). Before this time has expired you can make an explicit choice from the menu, or hit the <Esc> key to cancel the timeout. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Press <F1> again for more help; Some options may require switching to 'Expert mode'
Update BMGR for W2K CHKDSK, fix BMGR-CHS values, and (re)set I13X dependancy
The bootsector for IBM-bootmanager on the disk selected here will be updated to avoid damage by the CHKDSK program from Windows-2000. Without this, the W2K CHKDSK may incorrectly identify BMGR as a damaged FAT partition and will try to repair it, breaking it ... As an alternative, you could apply servicepack-2 to Windows-2000. This function will also verify and fix the CHS values recorded for the bootsector and configuration data sector for BMGR. Finally it will deactivate the explicit 'I13X' check in the BMGR code that results in a dependancy on the IBM MBR 'I13X' signature. After this deactivation, BMGR can be used with other MBR code like Linux GRUB as well (see 'bmfix' documentation too). Note: To allow booting OS/2 with non-I13X MBR code, you should also perform a 'fixboot' on any bootable HPFS partitions that are beyond the 1024 cylinder limit. The MBR used MUST be able to start partitions beyond the 1024 cylinder limit, but does not need to set the 'I13X' signature normally required by OS/2 The standard Windows (XP) MBR does NOT work beyond 1024! To reactivate the I13X dependancy use 'bmfix -I13X' - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Press <F1> again for more help; Some options may require switching to 'Expert mode'
