Changes since 0.88

fixed an issue with debug output when performing Discop to ICS cards
fixed an issue when checking ZIDEFS based partitions past 512MB caused by ZIDEFS_SectorDiscOp being misnamed ZIDEFS_SectorOp
RISC iX type 1 (ST506/CHS) and type 2 (SCSI/LBA) partitioning now supported
fixed an issue with the OS version check in FS.ADFS and FS.HDFFS which caused the drives to be scanned twice
Partitions.ZIDEFS wasn't using the physical disc heads and sectors to convert the partition cylinder to LBA
fixed an issue with the Filecore middle zone address calculation, which miscalculated the address if zone_spare was greater than 255
some IDEFS partitions were not being linked to OS FileCore drives
merged ATA IDENTIFY response decoding for FNadd_drives_IDEFS into one unified function
Simtec drive detection added, using IDEFS_Enumerate and IDEFS_Enquire
APDL drive detection changed to use IDEFS_DriveFlags to avoid the Module locking if an IDENTIFY it send to a non-existent drive
non-FileCore partition check now only checks partition types 1 and 2 to avoid false positives and accounts for a negative head count in the Boot DiscRec
added some basic validation to the FileCore Boot DiscRec to avoid false-positives on drives using partitioning
added LBA limit checks to all IDEFS discop functions
added Simtec partition reading
fixed an issue in FS.ADFS which wasn't setting the drive prefix to "ADFS"
if an invalid non-ADFS partition is found, the first FileCore partition is no longer shown as an overlayed partition. This fixes Simtec partitions, which put invalid data into the non-ADFS partition words
split add_drives_IDEFS in FS.IDEFS into sub procedures for each IDEFS interface type to make the code easier to follow
split read_partition_table_IDEFS into su functions for each IDEFS interface type to make the code easier to follow
IDE model name wasn't being byte order reversed
Modified Formats.FileCore FNWriteDefectList to write Simtec/HCCS compatible boot records
FileCore wasn't zero terminating the drive name in the Disc Record
FileCore format wasn't setting the Disc Record filetype to &FCD
Simtec IDEFS partitioning now checks for the partition size being in the penultimate word in the Disc Record
HCCS now sets the Logical Device name, to avoid having to search for it in FNvolume_info_FileCore
FNvolume_info_FileCore modified to only search for the logical drive name if its not already been set
Restrict the max partition size to 512MB pre RO3.50
HCCS IDEFS now configures IDEFSDiscs to match the number of partitions
ZIDEFS write partition table added. Wimp modified to ensure the size of a new partition aligns with a cylinder to meet ZIDEFS restrictions

modified FNwrite_partition_table_ZIDEFS to allow for 0 ZIDEFS partitions
ZIDEFS wasn't marking the unusable area correctly for drives >2TB
switched ZIDEFS to use low level IDE commands to read/write
Lowered the default partition size pre RISC OS 3.5 to 495MB to ensure the LFAU is 1 sector
added Wizzo support
IDEFS and ADFS now show unformatted drives as fully unallocated space
ADFS now defaults drives to FileCore partitioning
Error boxes modified to support WindowManager versions below v3.50
FNupdate_window_title was corrupting memory
FNwrite_partition_table_ICS was writing an invalid CRC to the end of the partition tables
ADFS GPT/MBR support is now based on the ADFS Module version, instead of the OS version
ZIDEFS drive identification could result in an error being reported
ZIDEFS wasn't setting the partition limit for secondary drives
ZIDEFS was starting the first partition at LBA 0 to mirror the OEM. The first partition now starts at the second cylinder to avoid FileCore overwriting the partition table
ZIDEFS partition starts are now rounded up to the next cylinder to avoid overlapping the previous partition
added FNalign_partition_* to allow ZIDEFS to align new partitions to cylinders
ZIDEFS wasn't correcting the sector address to +1 when performing low level disc ops
Added FNcylinder_size(<drive>) to !RunImage for general use
Added Drive_Info%(<drive>, D_Addressing%) to track if a drive prefers CHS or LBA addressing. Modified FS.ZIDEFS and Formats.FileCore accordingly
Moved FNdecode_IDENTIFY into !RunImage and made it general use as its used by several filesystems that need to decode IDE IDENTIFY DEVICE
FS.ADFS, FS.HDFFS, FS.IDEFS, FS.ZIDEFS modified to use FNdecode_IDENTIFY
Adjusted the progress bar code to see if it now updates correctly
Deleting an ICS partition was failing to clear the partition table entry correctly
ICS partitioning wasn't allowing FAT partitions to be created
Added low-level IDE commands for ATAFS, which needs testing. It might identify drives and provide debug info to work out the partitioning scheme
Added PROCadd_unallocated_space as a general procedure that adds any unallocated/unusable space to the GUI
Update Partitions.* to use PROCadd_unallocated_space
Moved the Partitions.ATAFS/IDEFS/ZIDEFS code into their FS.* files to avoid them being loaded if the filesystem isn't present
Added PROCadd_unallocated_space and modified all the partition code to use it to add any unused or inaccessible areas to the GUI
Added FNcmp64() to compare two unsigned 64bit values
FNvalid_range wasn't checking the range correctly

FileCore no longer scans ADFS floppy discs when searching for a partition's logical drive name
Progress bar now refreshes the whole area to avoid stale Wimp updates
Added PROCadd_drives_progress() and modified all FS.* to use it
ZIDEFS *Configure ZIDEFSDrives now performed when the drives are reattached
ZIDEFS wasn't ignoring partitions that were 0 cyliders in size
ZIDEFS and ICS partitioning were not adding unallocated space between partitions correctly and were not allowing the area to be formatted
Modified the IDEFS read partition code to handle a bug in ICS IDEFS where later versions will report a drive failure if IDEFS fails to a valid partition table
Modified the FileCore partitioning code to always write a valid LBA 6 to work around a fatal bug in some versions of ICS IDEFS
ADFS based ST506 now use CHS addressing
MBR partition range validation altered to size-1
When restarting a filesystem the filesystem Filer Wimp task is now asked to quit, before RMReInit'ing the Module
Holding CTRL while loading, or selecting "Refresh drives" will cause FS drivers to scan for missing drives. Currently only applicable to ZIDEFS and HCCS
If scanning for missing drives, HCCS will check if IDEFSDiscs matches the number of accessible drives and will prompt to correct if different
HCCS will correct IDEFSDelay to 8 if its configured lower
If scanning for missing drives, ZIDEFS will check if ZIDEFSDiscs matches the number of physical drives and will prompt to correct if different
IDEFS wasn't falling back to general DiscOp 3 when the Podule is unknown, causing drives hosted on Risc Developments IDE to not appear
HCCS was not forcing HCCS partitioning
HCCS and Simtec were not forcing CHS addressing
Now checks for open files before restarting a filesytem and wlll prompt allowing the restart to be cancelled
Will inform if open files are going to be forcibly closed when known logical drives are being dismounted prior to formatting or partitioning. This cannot be cancelled, so is informational only
Now dismounts a partition's logical drive (if known) prior to deletion, formatting, or extending
MBR partitioning wasn't using the correct limits when adding unallocated space at the end of the disc
FAT will now check if a FAT volume is mounted by FAT32FS

MBR wasn't allowing four partitions to be created if the disc was formatted as a full-disc FileCore drive
MBR wasn't marking a reserved partition as a non-standard format, to prevent the previous partition from being extended into it
MBR now restricted to 2TB
"Refresh drives" menu is now shown when middle-clicking anywhere in the window
FAT32FS v1.60+ hosted drives will now use OS_FSControl 55/49 to retrieve the free space
MBR wasn't passing the first free LBA to PROCadd_unallocated_space, causing an unallocated area the size of the disc to be created
Modified MBR to track partitions as 64bit, to avoid the situation where a malformed partition size might wrap beyond a 32bit LBA
Format volume no longer refreshes the drives if cancelled
Modified the Wimp menu handler to allow items to move around
Added "Mount with FAT32FS" as a menu option on FAT partitions if FAT32FS is available and the partition isn't already mounted
Added Backup/Restore partition table for MBR, GPT and FileCore. As full-disc FileCore doesn't have a partition table, it stores/restores the first 6 LBA. HCCS and Simtec partitioning store LBA 6 from each partition. ICS partitioning stores/restores LBA 0 and 1
HDFFS wasn't allowing MBR, GPT or FAT to be used
RISC iX partitions were not being displayed

Increased minimum unallocated block to 2MB on IDEFS
Backup partition wasn't backing up the backup GPT
Moved all initialisation code into an Init overlay to regain 13KB
Moved HCCS hot-fix code from FS.IDEFS to Init to regain 2KB
Creating a new partition at max size was creating a partition that spanned all of the unallocated area, ignoring the filesystem limits. It now only uses the full unallocated area if Filecore is v2.51 or newer and there's less than 1MB remaining in the unallocated area
Max partition size is now limited based on the Filecore version:
< v2.91 (pre RISC OS 3.60)
512 MB
>= v2.91 (post RISC OS 3.60)
262144 MB (262 GB)
Adjusted Partitions.FileCore / FS.ADFS and FS/SCSIFS to observe the FileCore limits above
When formatting a new partition, it was not reducing the LBA count by 1 which caused FileCore to exceed its limit when formatting a 512MB partition pre RISC OS 3.60
Added progress updates to all format and partition table write code
Wasn't rounding up the partition size when setting the maximum size for a partition
ICS was writing the unusable area to the partition table

Debug output is now sent to Reporter instead DEBUG/TXT if its running
HCCS/Simtec were not adding unusable space after the partitioned area
Wasn't setting the default partition size to 502MB for FileCore 2.52 thru 2.90
No longer rounds the partition size up to the next MB
Fatal error handler modified to use legacy BASIC functionality only, to avoid infinite error loops
Updated the custom BASIC Module to BASIC 1.85 and added a 32-bit version
The bespoke BASIC Module is now loaded if inbuilt BASIC is below 1.85

Initialising a drive now accounts for 4K sectors when writing the boot DiscRec
When initialising a drive as HCCS or Simtec partitioning, the boot DiscRec is now marked with their respective magic identifiers, so the partitioning can later be distinguished from a blank or FileCore initialised drive
HCCS/Simtec partitions that exceed the drive size are now reported
ZIDEFS IDEop was causing a buffer overrun when reading from the disc
DiscOp's where not setting the disc size correctly in the temporary DiscRec

Known issues/caveats

Does not recognise FAT partitions embedded in a full disk FileCore drive, that have no accompanying MBR/GPT partition entry
Currently makes no attempt to link a FAT partition to an accompanying DOSFS file on the Pi (ie !Boot.Loader)
Does not calculate the free space in FAT12 or FAT16 partitions
Freespace on FAT32 may not be accurate as it shows the freespace as reported in the FAT header; it does not trawl the FAT itself to get the exact current freespace
GPT Basic partition contents are not checked for NTFS/FAT formats etc
It relies on FileCore partitions being mounted to display the free space
Does not detect drive insertion/removal
ST506 drive size detection may not work
Partitions with an overlayed FileCore drive will incorrectly show partitions that start after the FileCore area as being within the FileCore area
Bespoke SCSI partitioning is not supported (eg Castle, Oak, Power-Tec)
No attempt is made to identify GPT partitions on filesystems that do not natively support them
When initialising a Pi Boot drive on an SD card, the SD card cannot be hot-swapped if SD was used as the OS boot drive. The only workaround is to format the new SD via a USB adapter
URL's for Pi Firmware, RISC OS builds, HardDisc4 builds, NetSurf, SharedUnixLib, IconV, Tinct, PackMan, SparkFS are currently hard-coded into the app, so may not reflect the latest versions available when initialising a Pi Boot drive. PackMan will also not know about any of the pre-installed apps when the new SD is initially booted.

Extending
Partition Manager is designed to be modular, allowing additional filesystem support to be added without the need to alter the main program. Refer to the document below for details on internal variables, procedures and functions required to add filesystems, partitions and formats.
