Hi cr1818,

Here is some information on compressing drives I thought you might be interested in reading before you tried it on your system.


Compressing Drives? (95, 98)

In previous tips, I've mentioned compressing hard drives on

your computer. Yes, it is possible to compress your hard

drive and make A LOT more space available for use. So

should you?

The answer really depends on how you use your computer. If

you have information that you simply cannot easily transfer

to another hard drive and you're hard pressed for space,

then compression might be an option. If it's possible for

you to transfer data to another hard drive or upgrade to a

larger hard drive, then I would strongly suggest that you

choose that route instead.

There are some drawbacks to compression; read these, and

make your own decision:

- Compression initially takes a LONG time. During this

period, your data is somewhat vulnerable to data loss.

DriveSpace's logic is set up so that the program will to

attempt to restart where it left off, but it's still

possible to lose data.

- Compression works only on disks smaller than 2 gig.

Almost all new drives are much larger than this, so this is

not a viable option for them.

- Windows Me does not support hard-drive compression. Only

Windows 95 and 98 can compress hard drives.

- If you cherish every ounce of possible speed, realize

that the compression/decompression algorithm can cause

bottlenecks. Disk compression works because a compression

utility sits between the operating system and the disk.

Whenever a disk read or write is needed, it must pass

through the utility. Depending upon the level of

compression, this passage may take very large amounts of


- You cannot use FAT32 and compression at the same time.

- DriveSpace 3, with the highest level of compression, will

work ONLY on a Pentium system.

I know people who had nothing but problems from compressed

disks, and also know others who use compressed disks with

no problems at all. But given the low prices of today's

hard drives, I personally recommend avoiding compression
