External HD not working after updating to os x maverick 10.9.2

I have a late 2010 macbook pro just updated to os x mavrick this week. My toshiba external hardrive was working fine with os x moutain lion. the hard drive is showing up under disk utility and is working fine on a frineds macbook he also is running Mavrick. I have run disk repair and verified the disk useing disk ulitilty. The only thing i can not do verify disk permission. Has anyone had any similar problems or know how i can fix this issue. I have apple care but i am deployed at the moment nd can not make it into a store. thanks in advance for any information.

MacBook Pro, OS X Mavericks (10.9.2)

See if Toshiba has any firmware update to make itself compatible with 10.9. If the Toshiba has its own built-in backup software, don't use it, and use Carbon Copy Cloner instead. Ask Toshiba how to remove it.

Alternatively, get a different hard drive from http://www.macsales.com/

If you find a solution, please let us know your Toshiba hard drive model, and the solution you find, as others are having similar issues.

My hard drive is a toshiba canvio. After reading the post above DOC- 602. I went under system prefrences and saw Tuxera NTFS, under about I went to there website. I had to download a new version for OS X. After the install my computer automatticly restated I popped my hard drive in and it is working fine. It is only a 15 trail version, the paid version is $31. I will wait and see what happens after thr trail version and may have to pay the $31. Additaional info I plugged a WD my passort in to my computer and it did not read as well before I updated the Tuxera NTFS. I just checked and it also worked with out any problems. I hope this helps other people.

google "toshiba portable tuxera ntfs update"

Tuxera offered a FREE upgrade for existing users. The version included with the Canvio should be installed. Download and install the 2013.2 version from the product page. Just install as normal. Should work fine as a fully-licensed version.
