Re: Disk not recognised

[Neil Houghton]

Hi Peter,

 

In your original post you said that the disk is not recognised by your wife’s 
MBP but that it mounts fine to your own MBP and content is seen as expected - 
so just a couple of thoughts:
Is it possible that the original problem was either caused by or resulted in an 
actual problem in the USB port(s)/bus on your wife’s MBP – have you since 
connected another, known to be good, external drive to this MBP and does 
everything work OK.
Assuming you prove that the USB ports are both OK on your wife’s MBP, try 
mounting the disk to your own MBP again and, assuming it still mounts OK, run 
the disk repair routines from your MBP (at all levels) and see what errors it 
can find and fix.
To me, it seems like you are assuming that you have a problem with the external 
drive caused by the disk being ejected improperly – and I am not ruling out 
that possibility - however the fact that the disk seems to be working fine on 
your MBP but cannot even be seen by Disk Utility on your wife’s MBP seems 
strange to me. I would definitely want to first rule out any USB problems on 
your wife’s MBP (step 1 above). Assuming that all checks out, step 2 might let 
you “sneak up” on any problems with the actual drive ;o)

 

 

Just a thought.

 

 

Cheers

 

 

Neil

Hi, I’ve been continuing to attach and wait for the drive/volume to mount, no 
mount showing on desktop or in Disk Utility. Numerous attempts at this in both 
USB ports - still nothing showing. 

 

I decided just for safety I would make a copy of the two Photos Libraries 
(~500GB total) on this drive over to my external drive and make sure they’re 
not corrupted. That finished overnight and this morning they open up fine on my 
MBP and all photos/videos present in both libraries. I turned off TM for my MBP 
in the mean time during this process. 

 

Whilst I haven’t done this yet. I was thinking I will just erase and reformat 
the drive, copy the library files back and then reconnect. No big deal with 
this except I am certain Time Machine will see it all as new file path 
(reformatted drive) or files and then create another ~500GB into the backup 
file for what is unchanged data. 

 

The alternative to this is to erase/reformat the drive and then restore the 
library’s files from Jo’s TM backup sometime prior to the fault occurring 
Saturday eve. I think TM would then set about backing it up again so same 
outcome. 

 

Before I go down this path, any last comments about how I could recognise this 
drive on Jo’s MBP? Any commands in Terminal that might help?

 

At least WCE followed through yesterday, one good outcome for the weekend... 
Dockers did look good for the first half.

You will keep receiving the Error: ‘Disk Utility can’t repair this Disk etc 
because the drive has not been ejected properly’

But keep hitting Repair Disk until it eventually runs correctly through and 
completes the process of repairing the drive.

4. Disconnect the Drive correctly and remove it from the USB port.

 

Let’s know if it gets rid of the Notification notice when the external is 
connected again to the MacBook.

Re: Disk not recognised

[Ronni Brown]

Hi Peter,

You have probably sorted the problem of the external drive by now.
I’ve been busy and unable to get back to you before now.
What I would suggest is:
Go to System Information utility, and see if the external drive is showing up 
under USB section. 
When it is trying to get mounted, OSX is launching a process "fsck_hfs". It's 
the same process that appears when you're performing "first aid" on the disk, 
so the OSX is trying to check the disk before mounting it.

So if the external is showing under USB in System Information - Force quit this 
process in Activity Monitor utility, then the disk should appear in Disk 
Utility, and you should be able to perform First Aid on it manually.

The Pies are beating Carlton... The Pies must beat Carlton!

Number keys do not work

[Michael Hawkins]

The number keys on my MacBook Pro  (17 inch, late 2011)(macOS High Sierra 
10.13.6) have stopped working (other than the key for “0” and “)”. I’m using my 
bluetooth keyboard to write this email.

The other keys in the row that includes the number keys do work, but the keys 
for symbols such as @*%^& do not.

I have run Disc First Aid.
 T
Any suggestions?

Thank you,

Michael Hawkins
