Remount Hard Drive Mac

External disks such as external hard drive, thumb drives, and SD cards are frequently used as extended storage for digital devices or portable media for file sharing.

Using physical external disks will sometimes encounter unexpected situations. For example, when you connect an external disk to a Mac, the disk becomes readable but not writable.

  1. A drive formatted in this fashion can be swapped between a Mac and Windows PC. However, you might choose instead a format you can use easily with OS X, Windows, and Linux.
  2. Asked 8 years, 6 months ago. Active 1 month ago. Viewed 1.3m times. I'm trying to mount an hfsplus filesystem in a Xubuntu 12.04 VM (kernel version 3.2.0-23-generic) but when I type mount -o remount.

Select '1 Partition' from the drop-down menu (or more, if you have specific need for more than one volume). When you select a new partition layout from the drop-down menu, each new partition will automatically be formatted to Mac OS Extended (Journaled) by default, but be sure to double-check this by selecting each in the partition diagram and then choosing the format for it.

The read-only state could result from limited file control, unsupported NTFS access or corrupted disk protection. We will look into each cause and illustrate detailed solutions.

If you know the cause, you can jump to the specific case and find the solutions. If not, read through the article to get the read-only disk problem resolved.

Case 1: You have read-only file privilege over the external disk

It happens often if you get the disk from another hand. The previous owner has set up read-only permission to this disk to protect data from unwanted changes.

If the read-only permission was set up by third-party software, you will need the same software to change the file permission. If the permission was set up on the Mac computer, follow the following steps to change read-only files on Mac.

  • Step 1: Connect the external hard drive to the Mac and wait for it to be mounted on the desktop.
  • Step 2: Right click the icon of the external disk and select Get Info.
  • Step 3: Unfold Sharing & Permissions at the bottom. A message ' You can only read' will be shown underneath.
  • Step 4: Click on the lock at the corner and input your user name and password.
  • Step 5: Click the Read only under Privilege of your user name and select Read & Write.
  • Step 6: Click on the lock to ensure the change.

If you are the administrator of this computer, you can also tick the box in front of 'Ignore ownership on this volume' and then input your admin password to be able to write to the external disk. Vlc not working on mac.

Case 2: macOS has read-only support to NTFS-formatted disks.

If the restrained file permission is not the cause, file system incompatibility could be the roadblock. Still in the Get Info window, under General information, you can see the Format is Windows NT File System.

NTFS is the proprietary file system by Microsoft and macOS only allows read-only access to NTFS. When using an external USB drives such as external hard drive, solid-state drive or thumb drive, you will find you can't store any files to it and existing files are locked or read-only.

To enable full NTFS read and write access, you can modify macOS kernel extension through commands. But it will become tedious because you need to do it every time you restart your computer.

Another one-for-all solution is to back up the current files and format the disk to FAT or exFAT. The drawback is that it is time-consuming especially when you have tons of data to back up.

We recommend you install free NTFS for Mac to read/write to a Windows NTFS drive.

  • Step 1: Download iBoysoft NTFS for Mac or any other app you may be interested in.
  • Step 2: Install the app and launch it following the onscreen wizard.
  • Step 3: Read & write to NTFS-formatted disks freely if the disk is automatically mounted in read-write mode. If not, manually unmount and remount the disk by yourself.

Case 3: The external drive becomes read-only because it is corrupted.

Most times, when a disk is corrupted, the macOS is unable to mount it or shows 'the disk you inserted is not readable by this computer' error when it is plugged in.

It is rare that a corrupted disk still can be viewed as usual. However, in a certain scenario, the disk still can be mounted in read-only state to prevent data overwritten from any writing activities.

Drive

This could be a warning sign that your external storage device is failing. You should get hands on saving your files and fixing the corrupted disk.

  • Step 1: Move your files to another destination to make sure they are safe before the disk completely stops working. If necessary, use professional data recovery software to restore important files.
  • Step 2: Open Disk Utility and find the disk on the right sidebar. Disk Utility can be found in Applications folder in Finder.
  • Step 3: Right-click on the disk and select Run First Aid.
  • Step 4: Eject the disk safely and reconnect it to the Mac if the disk still can't be mounted to be editable.

First Aid can only fix minor software errors on a storage medium, so big chances are that it may fail to fix the read-only disk.

To remove all errors, you can format the disk in Disk Utility using Erase option with an adequate backup first.

Conclusion

When external hard drives, SD cards, or USB flash drives suddenly became read-only, don't panic. The problem is totally solvable with free and easy solutions.

We want to remind you again, formatting the disk to get rid of NTFS file system or repair the corrupted file system will delete all files on the portable disk, so remember to back up files first when conducting erase option.

Introduced as the first sub-$1,000 Macintosh in October 1990, the basic Classic came with 1 MB of RAM, a SuperDrive, and space to mount an internal SCSI hard drive. The hard drive version came with 2 MB of memory and a 40 MB hard drive. RAM expansion was via a 1 MB daughter card with two open slots, which could accept a pair of 256 KB or 1 MB SIMMs. This made memory upgrades far easier than on the Plus or SE, since the motherboard didn't have to be removed. At the same time, it means you should avoid any used Classic without 2 MB or more memory unless you have a source for the memory card.

What Apple was thinking releasing an 8 MHz computer so late in the game is beyond me. By 1990, 8 MHz was just too slow for practical use, although that didn't keep Apple from selling it or people from buying it. At this point, a 16 MHz Classic would have been sweet (see our review of the 16 MHz Brainstorm upgrade in a Mac Plus for details on that).

One new feature on the Classic was elimination of the brightness knob. Instead brightness was controlled with the Brightness control panel.

A feature unique to the Classic is the ability to boot from ROM by holding down command-option-x-o at startup. The ROM Disk is called 'Boot Disk' and is 357 KB in size. The ROM Disk uses Finder 6.1.x and System 6.0.3 – this combination is specifically designed for the Classic. The only control panels are General, Brightness, and Startup Disk. MacsBug and AppleShare Prep are also part of the System, which loads into 294 KB of the Classic's RAM. Because this is in ROM, there is no way to add anything to the ROM Disk.

The Classic was the last Mac to use the 8 MHz 68000 CPU. Looking at all the compromises involved in its design, we label the Classic a Limited Mac.

You can convert a non-working compact Mac into a Macquarium. (Please, don't even think of converting a working one – you can always find someone interested on the Classic Macs or Vintage Macs lists.)

Tips

  • Don't buy a used Classic without the memory expansion board unless you have one available elsewhere.
  • If you have less than 4 MB installed, upgrade to 4 MB. You can often find pulled 1 MB SIMMs (removed from other Macs during upgrade) inexpensively.
  • Memory permitting, set the disk cache to 128k.

Cautions

  • Apple discontinued support and parts orders for this model on 2001.01.01. You may be able to find dealers with parts inventory either locally or on our parts and service list.
  • Never connect an Apple II 5.25″ floppy drive to the Mac's floppy port. Doing so can ruin the floppy controller, meaning you can't even use the internal drive any longer.
  • Macs with black-and-white only displays (1-bit, no grays) may find Netscape Navigator 3 makes it impossible to view some pages and sites. The workaround is to use Navigator 2.
  • Reliably supports serial speeds to 19.2 kbps, although default is 9600 bps. May have better throughput at 28.8 kbps despite some dropped and retransmitted packets. Throughput with a 56k modem may be limited. See 56k modem page. For more information on Mac serial ports, read Macintosh Serial Throughput.
