Looks like a WD 250GB drive will probably work - only one way to find out!
This isn't looking very promising, I might be better off sticking with 10.6.8 at this rate.
Did you get my PM about some tweaks for SMB Sheridan?
Eseentially, Mavericks is SMB2, but laughably, XP, W7 and W8 have different troubles connecting to it. The most common problem is the protocol for connecting, or the number of times connecting. (rejecting the credentials, then accepting them the 2nd time around)
Most commonly, checking the log you'll see the username has included the domain as well (ex. 'domainname\username')
Here's the notes I've compiled to help me out so far:
Here's the value we have the HKEYLOCALMACHINE\System\CurrentControlSet\Control\ Lsa\LMCompatibilityLevel
Windows XP set to: 3
Windows Vista and Windows 7 set to: 1
Windows 7 Fix:
1. Enter “gpedit.msc” in the Start Search box.
2. Open “Computer Configuration”/Windows Settings/Security Settings/Local Policies/Security Settings.
3. In the right pane, enable the following policies:
Manager Authentication Level to "Send NTLMv2 response only"
WE MAY NEED TO UNDO THIS the previous setting is:
Send LM & NTLM - use NTLMv2 session security if negotiated
Force your Mavericks Mac to use SMB instead of SMB2.
To do this you'll need tocreate a nsmb.conf file in your home directory with the path ~/Library/Preferences/nsmb.conf.
There are several ways to do this. First, you can up a terminal from Utilities and paste in the following line from the shell prompt:
echo "[default]" >> ~/Library/Preferences/nsmb.conf; echo "smb_neg=smb1_only" >> ~/Library/Preferences/nsmb.conf
The above must be entered as a single line with a return at the end. You can also create this configuration file with a text editor such as vi from the terminal. Do not, however, try to create this file with a word processor. You'll end up with formatting characters in the file that will ruin it for configuration purposes.
You can also try forcing Mavericks to use the older SMB variant,Common Internet File System (CIFS). To do this,simply edit your server connection URL so that it uses CIFS. Use the Finder to choose the "Go" menu and select "Connect to Server..." (or just use command-K) and type "cifs://YourServerName" and hit Return; the server should mount. If it doesn't, try entering the share's designation as well, e.g. "cifs://YourServerName/YourDriveName."
I did get your pm, sorry I haven't replied yet as I've been a bit distracted the last few days.
I'm in two minds about whether to stick with 10.6 or move to 10.9 now. Difficult to test unless I take a couple of Macs offline to set up a mini test environment.
