Q: Mavericks corrupts external hard drive
-
Dec 11, 2013 7:56 AMby jeffsphoto21,BTW - I believe Western Digital does make the internals for the G Drives, but I reformatted them with Disk Utility before using. Never had a problem with them under Mountain Lion. And never used them in anycase with Mavericks. Checked Activity Monitor in Mavericks and dont see any WD. Still had the problem with the Seagate in Mavericks.

Dec 11, 2013 8:01 AMby Drew Reece,Activity Monitor is not a good way to check - many jobs launch 'on demand' they will appear & then disappear.
The job may launch when it finds an external WD HD, or when another set of conditions are met…
Can you check via EtreCheck or the command I mentioned back at

Sorry, but I guess I keep missing the point here. My Seagate drive now appears unformatted.
What exactly do you mean by unformatted? An unformatted drive has no partition scheme, no partitions, no file systems at all. It won't mount, won't show any errors, etc. Is that how your Seagate appears?
If not, please describe what (if anything) Disk Utility shows for its partition scheme, & the names & types of its partition(s).

Dec 11, 2013 9:53 AMby blindeyetom,estApple Yes, it does seem the WD RAID Drives need to be set up by the WD software. That's a bit troubling in itself, seeing as disk utility has those tools. If disk utility will not work in configuring them from the factory setting of RAID 0 to RAID 1 then perhaps uninstall the software after configuration, or check and triple check with WD & Apple before any OS upgrades that there's no compatability issues. I tell you, I thought I was paranoid before about this stuff but obviously not enough!
R C-R Indeed, I understand stuff sometimes (often) slips through the beta testing net, but this appears to have been a major incompatability issue between Mavericks and the WD software. Yes a relatively small percentage are using RAID drives (WD and other manufacturers) & have WD software installed & updated to Mavericks & plugged in via Firewire (which seems to be another common piece ofthe jigsaw) and have then encountered the 'reformat as MyBook' issue, but it's still occured enough to be quite a widely reported problem. I'd have thought a regular and thorough testing of the entire product range with all the interface cables and the software on an up to date OS would have been a given in the WD office, but then what do I know.... I also get the points you raised in regards as to why they may not be sharing information. Sometimes though I get to acting like the kid who asks 'why?' and won't take 'because it is' as a satifactory answer.... And though I may not understand everything right away, but that's how we learn right?
In any case, I personally have learned a few more tips and tricks on figuring out what's going on with my machines through this thread, so am finding it useful still...

Drew I looked at EreCheck and it something that I would not download after reading, sorry I won't be able to help. My Mac is running fine.
I wish to second PlotinusVeritas on his recommendation for EtreCheck.
I have had users run and post the reports here. After analyzing the report, we saw many things about the Mac that the owners were not even aware. It is a great tool for troubleshooting.
I would be curious to know what you read that caused you to make your negative comments about it. Please share a link to what you read.

Dec 11, 2013 10:21 AMby PlotinusVeritas,A detailed search of the Seagate forums yields only one match and mention as per this repartitioning and HD corruption.
As to specifics on the one post there, no details useful are given and WD software could, or course, be in play.
As I implored on Page 1 of this thread, unless there is dire necessity,....never ever use hard drive software.
Got a new HD?, plug it in and format the trashware off it, then use it.
Im still convinced, until it is shown otherwise,...that the WD smartware or otherwise WD-ware has / is / was causing a fsck corruption
Apple:

If you do run fsck, it is best if you use -n and -f flags so that it will not actually modify the volume.
Because running fsck to repair a file system which is mounted for read/write operations can potentially cause severe data corruption or loss, the file system is normally checked while unmounted, mounted read-only, or with the system in a special maintenance mode that limits the risk of such damage
f = force fsck even if clean (preen only)
n = assume a no response
p = just fix normal inconsistencies
q = quick check returns clean, dirty, or failure
r = rebuild catalog btree
u = usage
y = assume a yes response
In preen mode (-y response), the conversion is listed and done
if possible without user interaction.
-y Assume a yes response to all questions asked by fsck; this
should be used with great caution as this is a free license
to continue (editing) after essentially unlimited trouble has been
encountered.

EtreCheckRead more about EtreCheck.
EtreCheck is a simple little app to display the important details of your system configuration and allow you to copy that information to the Clipboard. It is meant to be used with Apple Support Communities to help people help you with your Mac.
EtreCheck automatically removes any personally identifiable information from the output.
EtreCheck is designed to run on OS X 10.7 “Lion” and above. People report that it works on 10.6 “Snow Leopard”, but some features may not report accurate, or any, results.
The last paragraph is the reason for not downloading the app.

Dec 11, 2013 10:21 AMby Allan Eckert,OK. I was aware of that. I still don't see where you get your negative response of not downloading it from that. If it is about personal information that is just a safe guard to check the report produced to be sure you are not telling secrets to the world.
