Q: Did Mavericks drop support for express card SSDs?

(Follow up to the above message)

FWIW, here is what the System Information, System Report, PCI Card shows under Lion:

ExpressCard:

  Type:          AHCI Controller

  Driver Installed:          Yes

  MSI:          No

  Bus:          PCI

  Slot:          ExpressCard

  Vendor ID:          0x197b

  Device ID:          0x2363

  Subsystem Vendor ID:          0x197b

  Subsystem ID:          0x2363

  Revision ID:          0x0003

  Link Width:          x1

  Link Speed:          2.5 GT/s

(This is for a 48gb WIntec Filemate ExpressCard/34 SSD).

I think it may be Driver issues I use a Transcend express card to insert SC cards from my Camera (a Nikon D3200) Model a TS-RDF-1

IT caused a Kernel Panic. And I had to reinstall Maverick. If you insert the card Locks up the computer. I also have one fron SanDisk which don't like as well because it doesn't lock the card in place. I've inserted it and no issues.

I'll have to get intouch with Transcend to have them up date Driver.  I would advise all to contact  the various vendors giving trouble and tell them their driver files don't work with Mavericks.

I got the exact same word-for-word response.  I'd be curious how many inquiries they're getting.  I looked for the "as evidenced in the apple communitiy" and this thread is the primary 'evidence'.  I'm surprised it isn't generating more discussion than it is. 

In the past I've always held out for the 10.x.1 release, guess I should have this time too.

Same boat here.  17" MBP with a 96GB Wintec ExpressCard/34 SSD.  Working to get the driver loaded - the Menu Bar option to "Power off Card" still loads, though.

It's an Apple bug.  I initially thought it was a driver issue, but I've contacted every third party PCI card maker I use and got some new drivers from the GH release of Mavericks they tested w/ and the same results prevail.  No PCI card.  Nada.

This will be true for Sonnet, Caldigit, SilconImaging, Wintec and I'd imagine many many more.

I'm having the same problem

My Mac Pro is dead! since i upgraded.

Cant get past panic during boot.

t is a Apple BUG my PCI express, sonnet, MOtu, UAD Audio are all dead if i remove all the cards, it boots! but then what do i use the computer for Keynotes? I contacted the companys too they say it is Apple they said not to upgrade until apple fixes the pci buss bugs, and drivers compatibility issues.

How do i get to downgrade from time machine if it uses ESATA on a sonnet card? Recovery mode shows nothing, safe node cant even identify cards?

Clowns these beta testers. Apple needs to start using people like us that actually use their computers to make money and use external items like printers. Also Epson printers have problems my 20k printer will not even show up. Epson tech support stated to not upgrade.

Now i am SOL because of Apple again. Clowns at apple say do a clean install, but then you cant use any of your Raid farms, or audio or Film editing hardware or software or restore anything.

You NAILD it on the PCI express  buss issue. Apple needs to fix it asap! See they wrote the OS for there new computers comming in November.

Did you really just upgrade a production machine to a new OS that was only a couple days old? Without a clone of the old OS to restore from?

Shame on YOU. You can't blame Apple for that kind of stupidity.

just before installing Mavericks used SuperDuper to make a Bootable Clone of Mountain Lion (OSX.8.x) and as soon as the Cloning was over before I had to do anything else, I upgraded to Mavericks. Of course I received the kernel Panic. But shut down and started in recovery mode and just out curosity I unpluged my Transcend Express Card Then went to install OSX after Repairing premissions.  t downloaded and installed again. And worked this time.

I did have to Run Font book and get rids of 72 Duplicate fonts.

I have the exact same problem with my 96Gb Wintec Expresscard (boot drive).

But...

I have a second machine.  Both are running 10.9 and one still works fine with the express card.

Working machine - 17inch 2008 Macbook Pro

Not working - 17inch mid 2010 Macbook Pro

Now trying to upgrade the card in the older machine

Same here, with an Intel 80GB SSD in the main bay of my mid 2011 MacBook Pro (750GB standard drive in the optical bay).  Disk utility finds no problem with the drive.  I have attempted to find updated drivers for the SSD with no luck.  Re-installed Lion from my backup and it's working fine again.  Not sure if I should attempt another Mavericks installation, keep looking for a magic cure, wait for an update that will (maybe) solve this, or...?

Like KSC_Straker, I got mine to work (same card).  I did not redownload the driver though, just reinstalled it again after the Mavericks upgrade (which entailed setting my security preferences BACK to allowing installs of software from "unknown" developers).  After the install and a reboot, my sonnet card again allows my esata drive to mount.

So it seems like in some cases, Mavericks is deactivating drivers in some way and a resinstall fixes things.

Cool. Unfortunately, for those of us with wintec ssd express cards there are no mfg provided drivers. It used to "just work".

Unfortunately, searching on the model number of my Intel SSD doesn't provide any hits for drivers, so I can't even find any driver to install.

Playap[ixie, you're having a different issue. We are talking about expresscard SSDs, you are talking about a 2.5" SSD. different beasts.

FWIW- I have a 1TB Samsung SSD in my main drive bay (and a 1TB HDD in my optical bay) and they work just fine. No drivers.
