Desperately need help - important ext hard drive will not mount (com.apple.DiskManagement.disenter error 49244.)

[wfriedwald]

Help! one of my most important hard drives refuses to mount! (no, I wasn't smart enough to make a back-up)

I try to mount it in disk utility and I keep getting this message :



Could not mount “5V”. (com.apple.DiskManagement.disenter error 49244.)

can anyone help? I have tried using a different USB connecting device, and also tried mounting in different computers.

as you can see, the drive appears in Disk Util, but it is grayed out, and that is the error message I get when I try to mount it.

failing all else, can anyone recommend a good hard drive recovery service in Manhattan?

thanks!

if it is important I would suggest getting a proper data recovery specialist to look at it for you, as screwing around with random ideas from the internet (which is what you will get here) if you don't know what you're doing is likely to do more harm than good.

live and learn, take backups next time.

Here is a thread with some information on "File system check exit code is 8"
Not sure if any of this will help, but might be worth a read.

"File System Check Exit Code 8" -- Disk wont repair

I'm not sure where this question should be posted. I've got a 3 tb Western Digital My Book Studio external drive that I use for backups. I bought it in July. I've got a 2 tb partition that I use for Time Machine and a 1 tb partition that holds old photos/music files. Last night, I started...

If the drive is formatted in HFS+, a product like DiskWarrior can more then likely correct the issue. DiskWarrior has been a staple for me for years. It works great on HFS+ formatted drives. It is not free though.

ALSOFT - Makers of DiskWarrior.

DiskWarrior is a utility program designed from the ground up with a totally different approach to preventing and resolving directory damage.

update: yes, I tried DISKWARRIOR - and yes, it seems to have worked! so far, so good. Totally worth the $130 it cost.

thanks for all suggestions!

I have been using DiskWarrior since OS X 10.2. It has saved my system many many times. I am glad it worked.

Now make your 3-2-3 backups!
