Q: Mavericks corrupts external hard drive

And what was that?

They acknowledged the problem and said it is being addressed.

Interesting. I would of been happy with that. They told me they would walk me through reformatting my drive and helping me wipe out the Mavericks install then reinstal;ling Mountain Lion. That was it.

If in fact they acknowledged the problem to you - and that they are working on it - where have they said so on their support pages? Have they?

I don't know. Where have they said they are not?

2 other 'interaction' examples that come to mind.

Spotlight re-indexing the other OS disk after an unsafe dismount (if you have to force reboot).

Launch services indexing the apps on the second disk. It means you can see 2 items in the 'Open in' dialog and Spotlight lists both copies too. They're minor annoyances.

Just don't assume you are safe from the possible corruption mentioned here, partition tables have been damaged in some cases (internal disks seem ok but there is no reason not to backup).

Noted. Thanks.

Internal disks are NOT immune to the problem.  After I had several external drives wiped (connected with eSATA, FW800, and USB that were WD and G-Tech), I pulled the plug on Mavericks when an internal drive was wiped on my Mac Pro with 4 internal drives.  The wiped internal drive was HGST and used for data only and not bootable.

I tried rebuilding the wiped drives under Mavericks but my system would always crash and leave another drive or the same drive wiped.  It was like dominos falling.    I used my Mac Mini with Mt Lion to rebuild my MacPro boot SSD from a cloned backup that I made prior to installing Mavericks.

The only external drive that I have NOT seen a wiping issue reported is a NAS drive.  I have a Drobo 5N that I was testing and it contained my last copy of the internal drive that was wiped.

I posted a summary back on Oct. 29.

Wow - I'm going to stay away from this thing !

BTW isn't it interesting how the fanbois are not lining up in a chorus to deny that this is happening? Where are they when you need them ?

Does anyone know whether the 10.9.1 release has address these issues?

This may help (or not....)

Prior to install Mavericks on my macbook pro, I run it on an external drive. I had no problem with the internal disk. Everything worked nicely, slower because of the external disk, but nicely. Based on that I decided to use it as my main SO.

Mavericks is starting to sound like a poorly presented high school project. I've been at this problem with two external drives for over two weeks now and no constructive sure-fire resolve.

All chat, call center and visit to genius at the Apple store have come up stumped.

WD haven't got a solution either and cant even get hold of Seagate :-(

All our Time Machine backups and scores of files and family pics are now inaccessable.

Does anyone know how we can be notified when this problem has a fix? I'm tired of sailing through the sea of complaints and forums with no definate fix. Everyone is guessing and grabbing at straws.

Thanks for nothing Mavericks Project Team :-(

I put what worked for me on this thread a while back and heard no replies. I'll repeat it and maybe this will help someone. What worked for me is plugging my WD in via USB and clicking on Migration Assistant. My Macbook Mavericks still doesn't read my WD but for some reason when I use Migration Assistant and follow the directions it worked. I selected the data, files and folders I wanted to Migrate to my Macbook and an hour or so later I had all I needed. What I am faced with now though is backing up Mavericks. I'm not sure what source of back up system to use is reliable. Hope this helps someone. Blessings! joe
