DSK1 FDR / V9T9 / TIFILES COMPARISON

These are the results of an comparison of the real TI99/4A file descriptor record (FDR), a V9T9 style file header and a TIFILES file header as created by the terminal emulator program Telco when uploading a TI99/4A file to a PC with a serial connection. The comparison is done with DIS/VAR, DIS/FIX, a TI basic and binary PROGRAM file of less than one sector, precisely one sector and less than two sectors. As I expected there is no difference between the header information of a TI basic program and binary data. To my surprise there was no TIFILES header created when uploading DIS/FIX files to the PC.

The physical layout of an FDR on a floppy disk is as follows: +---------------------------------------------+ 0 | | 2 | | 4 | FILE NAME | 6 | | 8 | | +---------------------------------------------+ 10 | EXTENDED RECORD LENGTH | +---------------------------------------------+ 12 | FILE STATUS FLAGS | NUMBER OF RECS/SEC | +---------------------------------------------+ 14 | NUMBER OF SECTORS CURRENTLY ALLOCATED | +---------------------------------------------+ 16 | END OF FILE OFFSET | LOGICAL RECORD LENGTH | +---------------------------------------------+ 18 | NUMBER OF LEVEL 3 RECORDS ALLOCATED | +---------------------------------------------+ 20 | DATE AND TIME OF CREATION | 22 | | +---------------------------------------------+ 24 | DATE AND TIME OF LAST UPDATE | 26 | | +---------------------------------------------+ 28 | | 30 | | ~ DATA CHAIN POINTER BLOCKS ~ 252 | | 254 | | +---------------------------------------------+ FILE NAME: Contains the file name of the file. The file name can be any combination of up to 10 ASCII characters, except for the space or period characters and the null character. The name is space filled to the right in case of less than 10 characters. EXTENDED RECORD LENGTH: Contains the record length if it is a data file and has a record length of greater than 255 bytes (not TI original). FILE STATUS FLAGS: Defines the data type of the file. The flags are as follows with bit 0 being the least significant bit: bit 0: Program / data file indicator 0= Data file 1= Program file bit 1: Binary / ASCII data 0= ASCII data (DISPLAY file) 1= Binary data (INTERNAL or PROGRAM file) bit 2: Reserved bit 3: Write protect flag 0= Not write protected 1= Write protected bit 4: Reserved bit 5: Reserved bit 6: Reserved bit 7: FIXED / VARIABLE flag 0= Fixed length records 1= Variable length records NUMBER OF RECORDS PER SECTOR: Contains the number of records that will fit into a sector in the case of data files. In the case of FIXED length records the maximum LOGICAL RECORD LENGTH is 255 and the NUMBER OF RECORDS PER SECTOR can be calculated by 256 / LOGICAL RECORD LENGTH. In case of VARIABLE length records the maximum LOGICAL RECORD LENGTH is 254 bytes and the NUMBER OF RECORDS PER SECTOR can be calculated by 254 / LOGICAL RECORD LENGTH. NUMBER OF SECTORS CURRENTLY ALLOCATED: Contains the number of sectors allocated to this file. END OF FILE OFFSET: Contains the offset of the first free byte into the last sector used in case of a program or variable length file. A variable length record always starts with a record length and is closed with a >FF byte. The END OF FILE OFFSET points to this location. If a new variable length record is written the value >FF is replaced by the length byte of the new record. If the new record does not fit in the free space of the current sector, a new sector is allocated. Because a sector of a variable length file always ends with a >FF byte the maximum length of a record is 254 bytes (256 - 1 byte for the record length - 1 end byte). LOGICAL RECORD LENGTH: Contains the logical record length of a data file. If this entry is zero and it is a data file, then the record length is given in the EXTENDED RECORD LENGTH at bytes 10 and 11 ((not TI original). NUMBER OF LEVEL 3 RECORDS ALLOCATED: In the case of a FIXED length record files, this contains the highest record number actually written to. In case of VARIABLE length record files this contains the highest sector number actually written to. Note: The bytes in this field are in reverse order. DATE AND TIME OF CREATION: Gives the date and time the file was first created on the disk. The meaning of the first (TIME) word is as follows: xxxxx xxxxxx xxxxx Seconds/2 Minutes Hours The meaning of the second word (DATE) is as follows: xxxxxxx xxxx xxxxx Day of month Month Years%100 DATE AND TIME OF LAST UPDATE: Gives the date and time the file was last written to. DATA CHAIN POINTER BLOCKS: Each data chain pointer block consists of three bytes which indicates a cluster of contiguous sectors. The three bytes are broken down into two three nibble blocks. The first three nibbles indicates the first sector number of the cluster. The second three nibbles indicates the last sector number of the cluster. Byte1: N2 | N1 Byte2: M1 | N3 Byte3: M3 | M2 First sector : N3 | N2 | N1 Highest sector: M3 | M2 | M1 The FDR data block below is what is found with a sector editor when reading out the catalog of a floppy disk. A V9T9 header is 128 bytes long and consists of the same data as the first 20 bytes of an FDR in the same order. A TIFILES header is also 128 bytes long and contains the 11th through the 20th bytes of the FDR. The first 8 bytes of the header is equal to "\x07TIFILES". The file information of the FDR is copied to bytes 9-16 of the TIFILES header. The rest of the 128 bytes may be filled with any other character. Most common is >00 or a >CA >53 combination. Another version of TIFILES header also contain the original TI filename in bytes 16-26.

EOF-----------^^


======================================================================
Filename: DV128_1P
Display Variable file with a size of precisely 1 sector.

The EOF offset points to the EOF flag (>FF) which is at the very last 
byte of the sector. Because records of a variable length file always 
starts with a length byte the maximum record length is 255. In this 
case the length byte is 255 (>FF), the EOF offset has a value of 0 and 
there is no >FF byte at the end of the sector. In general: the end of
a sector is reached when the read offset + record length + 1 is
greater than the sector size.

EOF-----------------------------------------------^^


======================================================================
Filename: DV128_2S
Display Variable file with a size of less than 2 sectors.

Notice that the first sector still contains a byte with a value of >FF 
to mark the end of the sector. This does not mean that every byte with 
a value of >FF marks a sector end. The first byte of every record 
(here always >10) is the record length. If a record length of >FF 
(255) is found (and the maximum record length is not 255 and therefore
this value is not found as the very first byte of a sector, see above) 
than this means the end of the sector, skip the rest and start reading 
the next sector.

The last record "ABCDEFGHIJKL" is written in a new sector because
in the previous sector there was no room for an record length byte
(>0C) the record (12 bytes) and the end of rector flag (>FF) thus a
total of 14 bytes.
