Read and Learn: How to Clean Up Mac Hard Drive Published On: 05 March 2018, by NewAdMacSoft The following guide will be the answer to the most annoying question: how to clear Mac hard drive and make your laptop perform better. Mac users can insert a Windows hard drive into their computer and be able to read (not write) the contents of their hard drive if they did not install a separate driver, for example NTFS-3G or Paragon NTFS.
Presentation
MacDisk is an utility for reading, writing and formatting Apple Macintoshmagnetic media on an IBM compatible PC, without any hardware modification ofthe computer and without any add-on.
MacDisk is a 32-bit application and runs under all recent versions of Windows(Vista and 7/8 included, even 64 bits).
Supported Media
- HD (High Density) floppy disks (1.44 MB),
- Plain hard disks without any capacity limit (see also our page onDisk Interfaces and on Hugedisks). Caution, Thunderbolt disks are not supported yet.
- CD-ROMs, pure HFS, hybrid (HFS/ISO 9660) and evenISO 9660 CD-ROMs with Apple extensions
- DVD-ROMs, which are in fact just huge CD-ROMs
- Iomega Zip cartridges, 100 and 250 MB
- Iomega Jaz removable disks, 1 and 2 GB
- External hard disks connected on the USB or FireWire (IEEE 1394) bus
- SyQuest cartridges, all capacities
- Bernoulli disks, all capacities
- USB media (keys, drives, token)
- Magneto-optical cartridges of 128 and 230 MB (3.5') and of 300, 350, 600, 650 MB (5.25').
Macintosh CD-ROMs are managed as read-only volumes. If you want to createMacintosh CD-ROMs or DVD-ROMs on your PC, please checkMacImage.
All kinds of Zip cartridges are supported(be it on SCSI bus, on USB bus, on IDE/ATAPI bus or on the parallel port).
Under Windows 2000 and higher, we don't use the Aspi layer any more, but a servicelaunched under the local system. See the MacDisk datasheet and the Lsdiorw page.
File System Compatibility
MacDisk manage the old HFS volumes (classical magnetic Macintosh media)and the recent HFS+format (also called Extended Mac OS, journalled or not).
MacDisk, when launched from a Windows partition created by the boot managerBootcamp on a Macintosh with Intel processor, can access the Macintosh partitionto copy files back and forth.
Why MacDisk?
MacDisk is aimed at all users needing to exchange data files between theMacintosh and the PC.
MacDisk is an indispensable tool for data exchanges between sibling applicationsthat exist in both Macintosh and PC (Windows) versions, like MS-Word, MS-Excel,PageMaker, Quark Xpress as well as transfering compatible data formats (Ascii,graphical files).

MacDisk Version 8.0
MacDisk is a 32-bit program. The latest version for Windows 2000 and higher addsmany new functions: it now supports all CD-ROM drives (SCSI, USB, IDE/ATAPI),all kinds of CD-ROMs (HFS, HFS+, hybrid, even multi-session ones). The 32-bitversion is much faster than former ones. For an example, a 80-MB file is copiedfrom the CD-ROM drive to the hard disk in less than a minute!
More, the new interface offers an Explorer bar to navigate the Macintosh volumeand a listview which allows to sort the items according to the name, to the type,to the data or resource length, to the creation/modification date and to thesignature.
This feature is very interesting, for an example if you get an USB token withboth Word and Excel files. A sort according to the signature will allow you tocopy selectively the Word files in a specific subfolder and the Excel files inanother one. Likewise, if you do DTP, you'll be able to copy selectively theTiff pictures, the EPS files and the layouts.
See our Preview Page on its newfeatures and its new user interface (with numerous screen captures).
And What About DD Floppy Disks?
MacDisk cannot read Apple Macintosh DD (400 KB or 800 KB) floppy disks.Apple chose to implement the GCR coding (Group Coded Recording) witha variable spindle speed to squeeze more data on the outer tracks of the medium.There are no software solutions to mimic that on the PC, and the existing hardware solutions become more and more of 'historical nature' (Central Point Option Board DeLuxe, Apple external floppy drive connected to a MicroSolution controller).
However, I recently learned that one of those cards is still available: theCatweasel board can read DD imageswith a normal PC-floppy (connected to it) as well as many other formats.
For the time being, the only practical solutions is to find a working Macintoshwith a floppy drive to copy the files onto another floppy (HD) or anothermedium.
MacDisk Features
MacDisk manages the Macintosh signatures and addsa corresponding extension to the files copied from the Mac to the PC.Conversely, MacDisk gives a signature to the files copied on the Macintoshvolume to make 'double-clickable' icons. The lookup table is freely editable(with the SignEdit utility).
MacDisk is a low-level disk utility and not a conversion program. It doesn'tmodify the contents of the files (to avoid yet another source of problems). Itis bundled with MacText, a little text converteraimed at some Macintosh text formats.
Cross-Platform Compatibility
Most big applications existing on both platforms open the files created onthe other platform. That is, Word for Windows opens Word Mac files. This holdstrue also for Excel, PageMaker, Xpress and many others. See ourHints & Tips for more information about convertingand transferring data files between Macintosh and PC.
Font Transfers
From version 4.5, MacDisk offers certain features to transfer and convertfont files between the Macintosh and the PC.

Want to use one external drive for both your Windows PC and your Mac? One hurdle you'll face is that, by default, these platforms use different filesystems. Windows uses NTFS and Mac OS uses HFS and they're incompatible with each other. However, you can format the drive to work with both Windows and Mac by using the exFAT filesystem. Here's how.
In this guide we're using exFAT instead of FAT32, another filesystem that both Windows and Mac can read and write to, because FAT32 has a maximum 4GB file size limit whereas exFAT can work with files as large as 16EB (exabytes). exFAT also performs better than FAT32.
You can format the drive from either the Mac or the Windows machine. However, if you want to use part of the drive for OS X's Time Machine backups, you should do this from the Mac, since there's an extra step to make the drive compatible for Time Machine.
How to Format an External Drive in OS X
1. Connect the drive to the Mac.
2. Open Disk Utility. The easiest way to do that is hit CMD and the spacebar at the same time and type in Disk Utility to find the program.
3. Select the drive you want to format.
4. Click Erase.
If you don't plan on using the drive for Time Machine, skip steps 5 to 11 below and continue with step 12.
5. Give the drive a descriptive name and leave the default settings: OS X Extended format and GUID partition map. These will format the drive in OS X's HFS+ filetype so it will be compatible with Time Machine.
6. Click Erase and OS X will format the drive.
7. With the drive selected in Disk Utility, click Partition.

8. Enter the amount of space you want to set aside for Time Machine. In this example, we're shrinking the Time Machine partition to 128 GB instead of allowing Time Machine to take up the whole drive.
9. Click Apply.
10. Select the new untitled partition so we can format it as exFAT for use with both Mac and Windows.
11. Click Erase.
12. Give the partition a name and select exFAT for the format.
13. Click Erase to finish.
Your exFAT-formatted drive or partition can now be used for both Windows and Mac. Note that using a drive frequently between Windows and Mac could increase the chances of file corruption, so make sure you have backups of the files on the shared drive and be extra careful about safely ejecting the drive before disconnecting it from your computer.
How to Format an External Drive in Windows

The instructions below are for Windows 10, but other versions of Windows from Windows 7 and up can also format an external drive as exFAT for use with Mac as well.
1. Connect the drive to your Windows PC.
2. Open the Disk Management tool. You can do that by typing 'disk format' or 'disk management' in Windows search or going to Control Panel > Administrative Tools > Create and format hard disk partitions.
3. Right-click on the external drive's partition or unallocated space you want to format and choose New Simple Volumeā¦
4. Follow the wizard to choose a volume size.
5. Assign a drive letter.
6. Choose exFAT as the file system in the Format Partition screen.
7. Give the volume a new name.
8. Click Next.
9. Click Finish.
Windows will format the drive as exFAT and you'll be able to use the drive on both Windows and Mac.
