I upgraded to Mac OS X v10.7 and it appears my Sandisk Cruzer Titanium USB flash drive isn’t recognized (no desktop icon). However, it shows up in System Information. 😕
iMac, Mac OS X (10.7.1)
Try using Disk Utility to repair it.

Do you have the Finder preferences set to show external drives?
Lion has them deselected by default.
Otherwise follow Kappy's suggestion. 😉
I ran disk utility and it says:
Disk Utility stopped verifying “Macintosh HD”
This disk needs to be repaired. Start up your computer with another disk (such as your Mac OS X installation disc), and then use Disk Utility to repair this disk.
Since I already installed Lion, how can I create a Mac OS X installation disc?
Yes, my Finder preferences are set to show the external drives.
Well, you were supposed to use DU to repair the SanDisk, not your startup drive. To repair the startup drive:
Repair the Hard Drive and Permissions - Lion
Boot from your Lion Recovery HD. When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
To boot from the Recovery HD restart the computer. After the chime hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
While plugged in, DU doesn't recognize my USB flash drive. It doesn't appear in the left column.
I recently picked up something that Disk Utility calls a "SanDisk Firebird" 8GB thumb drive. Plugged it in. The disk wasn't usable. Asked me to initialize. Took me to DU. Attempted to Erase the drive. Still sitting here half an hour later. I'm going to go out on a limb and guess there's something wrong with SanDisk under Lion...
I, too, have a similar issue. Mine is a SanDisk Cruzer Enterprise FIPS. It is fully recognized and mounted with my iMac without Lion. This USB drive worked similarly on my MacBook Pro until I "upgraded" it to Lion. When I inserted the SanDisk with Lion, I see the Cruzer image. When selecting that I only see the PKG to install. So I installed it again and rebooted. But I get the same Cruzer image and no prompt for password. The drive still works with my iMac, so I do not believe at DU would help any.
The Mac module on the SanDisk Cruzer Enterprise products no longer functions due to changes in 10.7.
There will be no future support for Mac with the Enterprise products - SanDisk issued an end of life November 2010.
This is an email I received from SanDisk:
"We have found that Apple made some significant changes to the USB stack in 10.7 (Lion) so no longer support the Cruzer Enterprise Mac modules.
Unfortunately the entire Cruzer Enterprise product range was issued an end-of-life from November 2011. As such there is no further product development, so in short, there is no fix or workaround for this issue."
And yet they keep selling them, and didn't make any moves to try to put together a fix in the ten months or so between the first Lion developer preview and the "end of life" for their product. Keep it classy, SanDisk.
I'm actually a member of the SanDisk Enterprise support team. There is an error in the end of life date that was emailed to tmavrk - it should have stated November 2010 not 2011.
I cannot comment on the retail devices that are experiencing issues on Lion.
With regards to the Cruzer Enterprise product range:
1) Resellers / ebuyers may still be selling their old SanDisk Cruzer Enterprise stock.
2) Developer time is expensive and many security vendors are cautious spending resources before an RTM version of the OS.
In fact the disk util has changed in Lion without any warning and caught out two full disk encryption vendors that I know of. The installation baulks requiring a script to be run to resize the root volume. Only then will their product install and encrypt the drive.
Are you saying a new script will allow hardware encryption with Lion OS?
I have a Sandisk Cruzer- you know, one of those regular ones you get from Staples.
Will that work with MAC?
So now we're at September 2013 and it still looks like nothing has been done to rectify the situation. I have an old SanDisk Cruzer 8GB flashdrive which works perfectly well on my WIndows PC, but not on my Mac.
Yesterday, I bought 2 SanDisk Cruzer "Pop" flashdrives yesterday, and both work fine.
Surely it wouldn't be too much to ask the folks at both Apple and SanDisk to get together over a coffee (I'll pay for it) and sort this out? Only one person is suffering here - the customer.
Sandisk compatibility issue with Mac OS X v10.7
