A lot of CD/VCD images distributed on the Internet are in BIN/CUE format, I've been told."

This is for example useful to divide live recordings into tracks where 2 second gaps would be kind of irritating."

CD-ROM Speed Tester — Thoroughly tests the reading speed of CD-ROM tracks for further critical use such as with a CD-R Software.
"This little utility was made because my brand new Teac CD-R55S doesn't support test mode (or RSJ doesn't support its test mode). Since the only real problem when no test mode is available is the read test (the write test will always succeed unless the CD was bad is the first place and this you never know until you actually write to the CD), and since HD are always fast enough, only duplicating CD tracks remains gloomy if not properly tested. Even if you have a brand spanking new 40x drive, if your CD has a nice big scratch right in the middle, you might never get more than 2x from one of the tracks on it, even if it's only for 1 second, it can be crucial. You will not know about this before it's too late (ie.: you get a brand new frisbee), or before using the test mode or this CD-ROM Speed Tester.
This utility will fake a read cache. If you use an 8 megs cache in your CD-R software, specify /c 8096 on the command line and the tester will take in account in its speed calculation the size of the cache, although it never actually uses one.
Reading CD-DA does no dejittering. If you need dejittering, it is usually too slow to do CD→CD copy anyway. Use another utility than your CD-R software to grab the track on your HD, and write it back to a blank CD.
If the lowest speed is 4.1x for example, I wouldn't try to copy at 4x, unless the area is very specific and you can come out of it without hitting the bottom using a huge cache. Also take in account that if your CD-ROM drives are not bus mastered, your CPU might be overloaded during copy which means CD-ROM Speed Tester might report higher transfer than your CPU is capable of when writing at the same time in your CD-R software."

"FAT32 Blanker is a tool that generates a file when giving some parameters. So it should be 100% safe by itself for everyone. Advanced disk tools like DFSee required to complete the job.
FAT32 support is somewhat limited in OS/2 world: we have an IFS that allows us to read/write data from and to FAT32 partitions, but we cannot format them. FAT32 Blanker somewhat fills this gap, with the help of advanced disk utilities such as DFSee."

Hogger — Shows disk space usage statistics by directory.
"This program allows the user to determine how much data is in a directory tree, not just a single directory. When the program is run, the user is asked to select a directory. The user does this by selecting a file within the directory of choice. Once the directory has been selected, the program will look at all files in all directories, and collect sizing information.
Once the program has selected its data, it produces a chart. The chart may be viewed as either a Bar or Pie chart. Letters are used as symbols for the directories in the chart. Under the chart there is a list box filled symbols, each directories name and the exact size in Kilobytes held under that sub-directory.
This program is useful for determining the true allocation of your hard drives space. This way you know where to focus cleaning efforts. It can also be helpful for determining how many disks will be needed to copy an entire directory structure."

KORT_IMG — Compress DOS images booted on a floppy disk.
"KORT_IMG converts a large disk image into a smaller one. The program shrinks the length of a bootable image to the total length of all files as mentioned in the directory of the diskette. So it is of vital importance to align the files on the diskette before the disk is converted into an image (VMDISK). No unoccupied clusters must be present between files. It will ruin your image.
The original disk image is not changed. A new image is produced, named KORT.IMG. If you fill in KORT.IMG in the settings of a "DOS from Drive A:" icon, you will have a plain DOS session, occupying minimal memory."

Spacehog — Hide diskspace above 2G-512b.
"This PUBLIC DOMAIN program helps you maintain the amount of free space in the specified drive to under 2G-512 Bytes. (Because HPFS allocates space in 512 byte units.) Thus stopping programs using 32-bit signed integer math from seeing space above 2G-512 bytes as negative.
If it can't find the \SPACEHOG directory in the specified partition, it behaves like a run-of-the-mill freespace reporting utility, albeit it can handle disk partitions up to 999,999,999,999 bytes in size. It reports the file system type and in the case of LAN drive, the NETBIOS alias name.
If it sees the \SPACEHOG directory, which you have to create explicitly, it will create dummy files there as needed to maintain the 2G-512 byte freespace ceiling for that disk partition (you may have to run this twice). The dummy files are named with simple integers, from 0 thru 99999999...
If the amount of reserved space needed is less than 2G-512 bytes, it will shrink or expand the size of the \SPACEHOG\\0 file instead."

TestDisk — Check partition and boot sectors, recover lost partition.
From the docs: "TestDisk queries the BIOS (DOS/Win9x) or the OS (Linux, FreeBSD, Windows) in order to find the Hard Disks and their characteristics (LBA size and CHS geometry). TestDisk does a quick check of your disk's structure and compares it with your Partition Table for entry errors. If the Partition Table has entry errors, TestDisk can repair them. If you have missing partitions or a completely empty Partition Table, TestDisk can search for partitions and create a new Table or even a new MBR if necessary."
TestDisk works with these partitions:
- BeFS (BeOS)
- BSD disklabel (FreeBSD/OpenBSD/NetBSD)
- CramFS (Compressed File System)
- DOS/Windows FAT12, FAT16 and FAT32
- HFS, Hierarchical File System
- JFS, IBM's Journaled File System
- Linux Ext2 and Ext3
- Linux Raid
- Linux Swap (versions 1 and 2)
- LVM and LVM2, Linux Logical Volume Manager
- Netware NSS
- NTFS (Windows NT/2K/XP/2003)
- ReiserFS 3.5 and 3.6
- UFS (Sun/BSD/...)
- XFS, SGI's Journaled File System

TFile
"TFile is a utility designed to present file system information in ways that have value to file system maintainers. LAN maintainers or single system users may find this utility helpful in tracking down the largest files on a drive, or the least recently accessed files on a drive.
I wrote this utility so that I could automate the removal of files which haven't been accessed in a certain period of time from a particularly full server disk."

Waste/2 — Calculate space lost to cluster size.
"Waste/2 is a utility program designed to calculate the amount of disk space lost to cluster size allocation. No matter the size of a file, full clusters must be allocated to hold them, regardless of if an integer number of clusters is required. For instance, a 1 byte file still uses a complete cluster."

EXT2-OS2 — Linux file system driver.
"ext2-os2 is a file system driver that allows OS/2 to seamlessly access Linux native partitions (ext2fs partitions) in both read and write modes. Once installed, Linux partitions appear as standard OS/2 drive letters.
My initial purpose was to get limited read only access to ext2fs partitions from my OS/2 system, so at the beginning, it was more a quick and dirty rewrite than a clean and full port of the Linux ext2fs file system kernel code.
I've improved it to reuse as much original ext2fs code as possible in order to get an almost full featured ext2fs driver on OS/2. I wrote a kind of IFS to VFS translation layer, and ported some Linux kernel services in order to minimize the changes required into the ext2fs sources. Now that ext2-os2 is 32 bits, these changes are minimal."
