BIOS Update for Thinkpad (x121e) in order to make Sandisk Cruzer Extreme finally bootable?

Question: BIOS Update for Thinkpad (x121e) in order to make Sandisk Cruzer Extreme finally bootable?

Hello, will there every be a BIOS update for Thinkpads (in my case x121e) so that it (the BIOS of the thinkpad) will finally be able to recognize and therefore boot from usb flash drives / sticks like Sandisk Cruzer Extreme??? (Once the OS is running, the drive is recognized just fine, but that's not what I'm here for.) My old desktop pc from 2006 has no problems with such a "modern" drive, but my 5 years younger x121e isn't able to boot from that drive? Come on, Lenovo, you can do better, at least you should...! I'm not sure, if that is the right place for such an inquiry, but as Lenovo apparently doesn't offer a proper support e.g. by email, I just try it this way. I once use the support by phone, only to find out that the lady on the other end had no clue whatsoever of computers and was just looking up answers in her system, which were, of course, not at all helpful. So, for now, this is my only hope, that someone from the technical team at Lenovo reads this and gets the BIOS programmers to work... Cheers,Mike [btw: I read about a similar entry where the guy finally marked his problem as solved just because he used another usb stick to boot the first one. That's not a solution, that's a work-around. I'm looking for a solution (= BIOS update), not a work-around!]

Preferred Solution: BIOS Update for Thinkpad (x121e) in order to make Sandisk Cruzer Extreme finally bootable?

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link (This link will automatically start a download of Reimage that you can save to your computer.)

Answer: BIOS Update for Thinkpad (x121e) in order to make Sandisk Cruzer Extreme finally bootable?

Hi, I have an x120e and when I get into the BIOS > Startup > Boot, I see the following list:Boot Priority Order1. ATA HDD0 Samsung SSD 830 Series (my main disk)2. USB HDD SanDisk Cruzer Fit (a tiny usb drive that is always attached and holds assorted files)3. USB CD4. USB FDD5. PCI LANThe device can indeed boot from a USB stick. I think you will have to follow this order of events: first attach the USB you want to boot from, yet boot only from your main hard drive, to let the system recognize the attached USB drive and put it in the Boot Priority Order list, then shutdown, restart and get into BIOS. F1: to either to change the ordering in the list to put USB FDD or USB HDD SanDisk first) or F12 (I think): to choose a temp device to boot from. Or....... (another thought), the USB you want to boot from hasn't yet been made "bootable" (I think you may have to go into diskpart > etc to set it active) so isn't recognized in BIOS. I've used a USB flash drive with my recovery partition on it to restore to factory state. That was also a Sandisk Cruzer USB. I've also booted directly into a WinPE sort of environment using another bootable USB made for the purpose of restoring from system images. Mine is an x120e; your x121e can't be much different. Cheers!

Hello there.
I have a Sandisk Cruzer usb and I accidentally erased the file that came on the usb itself and now the device is unreadable to some of my other devices (DVD Player, media players, ect.). I tried looking at the sandisk website for help, I tried google for about an hour and still can't find any thing thats even relevant to this matter. So if anyone knows how to fix this please help, I really need the usb to work again.

Hi,I want to update my laptop (Thinkpad T440p 20AW)bios to the latest version 2.24 released 04 Jun 2014, but I can't! As always I burn the iso file on a cd and try to boot with cd but after the first THINKPAD screen it doesn't go to the bios update screen and it returns to THINKPAD screen. I tried to install updates through an usb stick but the same. I mean moving(installing) the iso image on a usb and trying to boot with usb to update the bios but it doesn't work too. Here with F12 at boot time I choose the usb to boot but it doesn't boot and it returns to choose device list.Any advice?!

Answer:Thinkpad T440p BIOS Update Bootable CD doesn't boot

Is there something about that update that you really, really think you want to have? If not, forget it.  BIOS updates are often over-rated, and this forum is full of posts about bricked laptops as a result of a BIOS update going south.  Maybe the fact that you're having problems with this one is a signal from the muses that you shouldn't do it.

i just got a sandisc cruzer titanium, and have already screwed up. i have windows ME, which i thought was supposed to have the driver already loaded. so when i plugged in the cruzer, it said it recognized new hardware, and then a new dialogue box flashed up saying that i needed to reinsert my millenium cd. while my husband went to look for that, i unfortunately clicked OK on the dialogue box, then "cancel", and now i will not even recognize the new hardware. I don't know what to do next. anyone familiar with this scenario?

I have a buddy who handed me what a flashdrive, a Sandisk Cruzer Titanium 2 GB with U3, that he said no longer worked for him. Well several hours later, I can't make it work either. When the flash drive is plugged into multiple computers (XP x 4, Vista x 1 even though Vista is NOT supported), the light on the drive flashes and the computer attempts to find the "cruzer mini" driver, which will eventually fail (the light on the drive will remain on indefinately, however). I look in Windows Explorer and Disk Management and the drive is not recognized. I look in the device manager and there is an exclamation point next to exactly one "USB Mass Storage Device." I said screw this and brought out my big gun Recover It All software for data recovery and *IT* doesn't see the device. Interestingly, when the device is plugged in the Safely Remove Software button becomes available, but when I click on it, there is nothing to select (which tells me, "yes I see something but I don't recognize it"). I've attempted to install Sandisk's WONDERFUL drivers but they won't install UNLESS IT CAN SEE THE DAMNED DRIVE, which it can't. Bottom line: u3 drives suck. I know I'm preaching to the choir, but I wanted that to be excrutiatingly clear!

So here's my quesiton: I'm looking for suggestions on how I can force the recognition of a USB device that is not natively recognized by the Device Manager or Disk Management. Any ... Read more

Answer:cruzer sandisk problem

So you only tried saving your important work to the flash drive, and when that failed, you didn't save it anywhere else? Then your work is gone.

As for the drive, are you not able to create any new documents on it at all? Do you get any errors? Has it ever worked?

I have a 4gb cruzer thumb drive I labeled as "4gb drive". I also have a printer which I connect via usb when I need to print something. I labeled the printer as "printer". The thumb drive is the J-drive and the printer is the H-drive. The problem is somehow my laptop has confused the two. It calls the printer "4gb drive" and the thumb drive as "printer". Both items function without issue. I just can't rename them.
How do I rename each item? When I right click the icon, then rename the icon it goes back to the wrong name.

Windows cannot start this hardware device because its configuration information (in the registry) is incomplete or damaged. (Code 19)
Can this problem be resolved in Registry if so how WINDOWS 8

Answer:SanDisk Cruzer Micro 4GB

If you want to open the Registry Editor in Windows 8, you must first go to the “Apps” screen. You can get to the “Apps” screen even if you are on the Metro UI Start Screen or the Windows 8 desktop.
Step 1
If you are on the Windows 8 desktop, point the cursor at the lower right corner of the screen. Click the “Search” option as soon as it pops up on the left-side of the screen. If you are on the Metro UI Start Screen, point the cursor at the lower left corner of the screen and click the right mouse button. Now select the “Search” option on the context menu.
Step 2
When you perform either of the above actions, Windows 8 will load the “Apps” screen. Type “regedit” into the search bar located on the right side of the “Apps” screen.
Step 3
Click the “regedit” search result on the left side of the “Apps” screen. If you see a UAC dialog box, click “Yes” to open the Windows 8 Registry Editor.
Run regedit and navigate to registry key
HKEYLOCALMACHINE\SYSTEM\CurrentControlSet\Control\Class\ {4D36E965-E325-11CE-BFC1-08002BE10318}.
Highlight it and in the right pane, find the Upperfilters and Lowerfilters values.
Highlight each one in turn, right click and delete them.
Close regedit and restart the computer.
If in doubt make a restore point before making changes.

It appears to install ok on two other WIN98SE machines, but they cannot find the drive. I have installed and uninstalled it several times without success.

I recently purchased a Sandisk Micro Cruzer 4G with U3 formatting. I downloaded a lot of information of it and used it for several days before the device stopped working all together. It has a light that indicates power on it and while using it one day the folder closed and the light turned off. Since that moment I haven't been able to re-open the flashdrive.

I've only used it in my laptop- which runs Windows XP Service Pack2. My laptop still recognizes other flashdrives and the usb ports seem to be functioning normally.

There were a couple of things out of the ordinary though, when I used the cruzer. The flashdrive overheats and our AVG virus protection kept detecting a threat on the flashdrive itself. It only popped up when the stick was plugged in.

I have already browsed the forums and looked at other people's answers and tried all the suggestions. The stick does not show up using Device Management, re-booting the computer doesn't work, and it isn't listed under My Computer. So if anyone else knows how to make this stupid thing work--- PLEASE help me!!!! I would really like my files back since I cannot replace them.

After you connect the drive, go into My Computer and double-click on the driver letter corresponding to the U3 application and not the drive letter associated with the flash drive itself. You'll then be prompted to enter the password, and then you can browse the drive's contents or apply any U3 updates.

I've got some data stored on a 4GB Sandisk Flash drive I've had for a couple of years. Nothing critical, but I'd like to get it back. One day it was working and then it wasn't. I didn't drop it or damage it in any way I'm aware of. When I plug it into the USB port, no light on the device nor any indication of the usual systray icon that an external device has been connected. Just to be complete, I checked in Windows Explorer and sure enough, it's not there.

Any ideas/thoughts?

I am having this problem with my 8 gb sandisk cruzer when transfering files using windows me. When I connect my sandisk cruzer to a usb port it recognizes it but only shows that 615 mb is used . Then I try to transfer something it says write protected cannot transfer file. I am 100% sure that there is enough space on the flash drive. When I connect it to windows vista it worked fine. I also reformatted the flash drive.  Also when I try to transfer the same information on a cd it says the same error.

First off I have read a lot of the previous threads and cannot find one that fits my problems. I recently bought a sandisk Cruzer micro 1G and I put it into my laptop and it worked great. then I tried to move a document from my laptop to my desktop (Dell Dimension 2400) and I actually got it to work (I don't know how) but now everytime I put it in my desktop my entire computer freezes until I remove the Cruzer Micro. But it still works fine on the laptop (has worked on 2 different laptops) so I don't know if it is my computer or the flash drive.Help Please!

Answer:Sandisk Cruzer Micro gone wild

When the computer freezes, is the Hard Disk Access light on? Sometimes on my computer it just takes a while (1-2 minutes) searching for the driver for my USB stick. Try just leaving it in there for a while and seeing what happens.

I am currently trying to use my flash drive with my computer and it isn't working. It is a plug and play hardware that when plugged in, loads a progam (launchpad) to install the U3 program which is used by the flash drive to manage the programs and files within it. I am currently running Windows 2000 operating system and wasn't sure if the two just might not be compatable.

Answer:sandisk cruzer flash drive

It would appear that it should work with 2K. I just took mine in and plugged it into a 2K system, and I couldn't run LaunchPad, so maybe it's hit or miss.

I just tried another 2K system, and it loaded up fine. Don't know what was wrong with the first one, but it appears to work on 2K and XP here.

What minimum system requirements do I need to use a U3 smart drive?

My cruzer appears to work - the lights blink on the drive when you try to access it. But it can't really find the files. Still says the drive ISN'T FORMATTED.
Based on one post, I changed the drive letter away from the default F: to an unused letter. So far, so good.

But... No matter what I have tried, when I format it in a variety of ways, the info window works up to 99% complete and then tells me it can't format the disk. But won't say Why... So I have an unformatted Cruzer.

Answer:Related SanDisk Cruzer problem

Try formatting from a different OS or Computer or both. Then never format again, its flash memory not a hard drive. Fragmentation is essentially a non issue, and I don't see anything you are gaining from formatting over just deleting the file.

I have a Sandisk Cruzer Micro, running XP, and up until recently I had no problems. Now, whenever I insert the drive into a working USB port, the orange light on the drive just flashes 3 times, then a short pause, then flashes three more times, instead of usually always being on. I think it could be a hardware problem (concerning the drive itself) because while it was in the front USB port of my computer, it got knocked around back and forth a little bit. I looked inside the device, and none of the pins seem to be damaged or displaced, and when I opened up the plastic casing itself, all still seems well. Is there any thing else I can do to access the data on the drive? If it means resorting to soldering a new USB male head then by all means I'll do it!

I recently bought a cruzer Profile. The first time I used it I added fingerprints, Username and Password. Today I logged in (with a fingerprint) and deleted all the fingerprints, thinking I would be able to use it on my MP3 player. Now I can?t log in at all (or set up new fingerprints). The moment I insert my cruzer profile, it prompts me to run the software (unlock Cruzer Profile), and then it asks for a fingerprint. I've tried all ten and they all fail. I can't see how it will allow you to delete all ten and then ask you for one as you try to log back in.
I have tried formatting it, but it keeps coming up with "Windows was unable to complete the format".
My Computer and Device Manager shows 2 drives, one shows the Profile logo (Local Disk) and the other one Removable Disk. I can brose the Local Disk. There are several files (autorun, CruzerLoginSetup, CruzerProfile, CruzerProfileHelp, gdiplus.dll, tfm.dll, and movie clips). I ran the CruzerLoginSetup, witch installs the software and asks for a reboot, after that there is no way of accessing the software without a fingerprint, witch it keeps asking me. If I run CruzerProfile it directly asks for my fingerprint. I think I have tried just about everything.
There is no way that I can access the Cruzer Profile or software so that I can enter new fingerprints.
Has anyone had similar problems?
Is there any way to forcibly format the device and start from scratch?

Sometimes the drives just die. This shouldn't be a driver issue, do other flash drives work in the computer? Have you tried this drive in a different computer?

You could open up disk management and see if you can delete the partition and create a new one, or simply format the existing one as NTFS or exfat. WARNING: Doing this will cause you to lose any data you may have on the drive.

I've spent several hours attempting to get Vista (Ultimate) to recognize my Sandisk Cruzer (2Gb, U3, SDCZ6-2048, BE0608A1B). The flash drive works fine on my XP Pro notebook and worked on my Vista desktop before I upgraded to Vista.

This is the message I get after plugging the drive in (the light comes on for 3-4 seconds):
"USB devise not recognized. One of the USB devises attached to this computer has malfunctioned, and Windows does not recognize it. For assistance in solving this problem, click this message".

When I click the message I get a new window up which shows a list of USB Root Hub (8 ports), and one is listed as "Unknown USB devise".

I contacted Sandisk tech support three times and got three different answers:
1) Use the U3 uninstall tool from their website to uninstall and reformat the flash drive. I did that, but Vista still does not recognize the drive.
2) You are out of luck. Buy a new flash drive. The version I have (v 2.18) supposedly would NEVER work with Vista regardless of uninstalling and reformatting.
3) It is a driver issue. I was told to search for a Vista driver that would enable Vista to recognize my flash drive. After 2 hrs searching, I can't find anything.

I understand that the U3 software may not be compatible with Vista, but a formatted flash drive should not be a problem. It's a "dumb" drive. Or, so I thought.

I accidentally put my key through the washing machine and in the meanwhile, I am waiting for it to dry out so I won't short it out when I plug it in. Do the internal components of this product oxidize, so that I need to speed up the drying process somehow, or is it fine for me to leave to dry slowly?

Answer:sandisk cruzer mini 512MB

It should be OK if it dries slowly. Just be 150% sure that it's 200% dry before you plug it in. A friend was helping a guy clean some junk out of a back yard and in this junk he found an old Pentium2 IBM tower. The case hadn't been closed up properly and it had been sitting out in the elements for over 18 months: leaves in the power supply, mud, etc... He took it home, actually WASHED IT OUT with a garden hose, took it apart and let it dry in the summer shade for about 4 days. He hooked up a new power supply (the old one was a lost cause) and the darn thing WORKED, well, it posted. The hard drive was dead. Anyway, had an old 8gb HD laying around and he still has this PC running Win2000 to this day as an Office PC for Word, Excel, and internet business transactions. Runs like a champ!

U3 has been removed and is no longer on the drive.

I do not have access to WIN98, a computer with WIN98 and all the "HP Softpaq", and "X-format" links in ALL the threads for "drivers" are dead.

Answer:Sandisk micro cruzer huuugge problem

did you STOP the drive before removing it?
NEVER hot swap. ALWAYS stop flash drives before removing them.

If not, your data is corrupt. Also flash drives should NOT be used for essential data that is NOT backed up. Flash drives by their very nature are volatile.

You can download file recovery programs to try and recover some of your data - it may or may not be possible to recover all or some of it. The longer you wait and the more the stick gets written to - the less of a chance you will get your stuff back.

Unlike various threads I looked at, I want to reformat my SanDisk 4GB Cruzer Titanium Plus flash drive. It came with USB3 stuff that I don't want, and which hassles me every time. I just want 4GB that looks and acts like a single unrestricted USB drive when plugged into a WINXP or Vista PC. I would prefer NTFS, but I could easily live with FAT32. There's no data of significance on the Cruzer to worry about saving first.

I have a WINXP Pro SP3 machine, and a Vista SP1 machine. I could use either to do the reformatting once I learn how.

So far everything I've tried to accomplish this reformating has been thwarted, including using the DOS Format command. Can anyone point me to the procedure or other secret that will let me do this? Would appreciate any words of wisdom.

I've updated my U3 drive to the newest version. When I plug in it occupies J: (the "CD Drive") and K:. When I try to run the U3 launcher it tells me Windows has mounted it on a drive that was already occupied and that I can't start it.

Disk management won't let me change the drive letter of the CD portion of it, but it will let me change the other one.

Any thoughts?

Answer:Sandisk U3 Cruzer Micro won't load U3 software

The SanDisk drive you are seeing is a virtual cd drive not one generally available for use. That's part of the SanDisk builtin software package. Simply ignore that and look in the disk management tool at the 2gb, 4gb, 8gb, or 16gb actually less for each like 1.75gb, 3.75gb, 7.75, or 15gb roughly available depending the size.

With a reformat of the drive space will then become readily available in Windows where you can change the drive letter at any time. The screen here shows a SanDisk made into a usb key for the 64bit RC along with another one right above while the 96mb UI drive is actually only 96mb for the SanDisk program itself separate from the usable space.

Got a 16 GB SanDisk Cruizer flash drive and it did well - until I swapped my hard drive for an SSD.

Since the SSD conversion, the ReadyBoost file on it does not work - Windows won't use it because I have an SSD - that' fine. The real problem is the SanDisk became write protected - can't format, can't delete.

Don't have a problem with a 1 GB flash drive - a SanDisk problem?

Already tried rededit, going to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\StorageDevicePolicies and entering WriteProtect = 0

Answer:16 GB SanDisk Cruzer suddenly becomes write protected!

Well try to use a boot partition manager. This allows you to boot from a CD to manage partitions. You can use this to format your flash drive. Search google for boot partition manager.

Here's the problem. I have a Win. 98 in the other room and I have my MP3 player on it. I wanted to use my Cruzer Mini 512 to transfer files but it won't work. I've installed drivers directly from, but it still doesn't work. I've done it about three times (reinstalling that is), and the thing doesn't work. I don't have internet on it so I can't like scan the web for a driver or something like that. If anyone has a solution or has had this problem I could use some help. :suspiciou

It now reports itself as a Sandisk Firebird with 64Mb total and it is reported by Win7 Home Premium x64 as of type RAW, when I know it should be either VFAT or FAT32. Have scanned drive with Easeus Partition Manager (nada, except same report) and Minitool Partition Wizard Home Edition (also, same result). Still trying to figure out how to rebuild the MBR (which appears to have been corrupted by a badly-written Broadcom update!) but so far, no joy.

Since this drive was bought for me in March 2014, I think you can see the drive itself is not the issue. Anyone have any ideas what I can do? I am a computer professional, but this one has me puzzled. Badly.

Answer:Error with nearly-new 32Gb Sandisk Cruzer Glide

Here's another tool you might try. Highly regarded, but I have no experience with it.

TestDisk - CGSecurity

In my experience, USB drives are pretty flimsy and can just go bad for no apparent reason and aren't necessarily fixable. I had one suddenly show as "RAW" a few months back and could never get it fixed. Returned for RMA.

Ok, so I've got a new 4 GB flash drive to move all my pics/MP3's, doc's and what not over to, so I can do some formatting. My laptop is a Dell Inspiron B130. I plugged it into my USB port (and I tried both E: and F:, and had the same problem on both) and was able to move my MP3's and pics to it with Windows Media Player. However, I can't see it under "My Computer" so I can move my doc's and games to it. I was able to see it under "Safely Remove Hardware", and it showed up as already installed under "Add Hardware" (which it should! It's Plug and Play, no disc came with it). However, I can't find it anywhere that I can drag and drop files. I've tried right-clicking a file and checking "Send to..." and also "Move Selected Files" but it never gives me the F: or E: option. In trying to see if I could back the rest up on CD, I started up Sonic DLA. It couldn't read that I had a disc drive at all (which I obviously, do). I've spent 7 hours straight on this, and I'm at the point of wiping the whole 'puter and giving up all my addresses/programs/files. Can anybody give me any advice? Please?

EDIT to add: I forgot to mention that in my device manager, it says the device is working properly

anybody knows if it would work to replace the NAND chip from another U3? Does controller have ties to the NAND chip?
My problem is that the flash drive full of info is dead. The LED blinks few times and PC doesn't recognize it as a USB device. Seems the controller is broken. If I take a new drive and replace the NAND chip, hopefully I'll see my data (unless San Disk implemented some security features here).

I saw what was available in search on the Sandisk Cruzer.

My question is: What is the latest if anything on formating these thumb drives?

My install of Hirens to the Cruzer boots but issues a file not found error.

The format routine used was a tool from Hirens which invokes Grub4dos-- the Linux loader program.

How can I start over with this?

Erase Hirens which doesn't load

Reformat and put on the Raw Copy tool from HDD Guru to use as my
clone program. (I may have others to add.)

The cruzer boots but has a script to take it to Hirens and the Hirens issues
that file not found which-- Lon cannot find.

My memory stick was working fine, and all of a sudden it is telling me that it is either passworded or not found, I really do not want to format it again as I need to get at the documents that are on it. Please can anyone advise me what to do - is there anyway I can get the information off and even transfer elsewhere? Also, why did this happen as I always ensure that I ensure that it is safe to remove the stick from the computer before doing so.

This is really starting to annoy me. No matter what, this thing will not eject. It was working fine earlier today and just stopped ejecting properly. Even when using the LaunchPad ejection method, it still does not work. The drives show up in my computer even after hitting eject but they say not accesible. I have tried using unlocker, but it says nothing is locking the drives. So as you can guess I just unplug it, but whenever I try plugging it back in, the LED flashes for a second but goes out (as if it were disabled). This means I require a reboot. Forget rebooting normally, after an ejection ordeal, my computer hangs on shutdown/restart... So I have to use the reset button on my computer. After that I can plug in the drive and it works fine untill you want to eject... Please help.

Hi guys. I bought a Sandisk mini cruzer 512 pendrive 3 months ago. It was OK but 2 weeks ago it stopped working in any computer I plugged it in. The light would come on for 3 seconds or so and then it would turn off and it's not recognized by the PC at all. I suspect a pendrive hardware problem. I have read a lot of posts giving instructions to reformat, reboot and so on but none of these solutions work if your PC doesn't physically detect the pendrive. Before I throw the pen into the garbage can (and with it the 67$ it took from my pocket!), does anyone know if the pendrive could be brought back to life in any way?

W98SE computers are quite good for reformatting them in FAT32.

Brand new Flashdrive no longer working because of physical damage and yet I was told by a company they could retrieve the super important files for me for $375.

Here is a pic of the disk.

So I put into the computer USB port and it was working fine. I accidentally kneed it and the red back of the flashdrive cracked off but the green part stayed intact except that I do notice these sort of whitish cracks in the green part at the bottom of the chip. Does anyone...know how I can retrieve the data off this? Or even if it's possible. Although this company did assure me it's possible and they are pushed by Sandisk company.

Answer:Problem with SanDisk Cruzer Flash Drive

Welcome to TSG shansg!! Hope this helps...

At work you probably have a network drive mapped to the Letter the FlashDr wants to use. On the work PC disconnect the network drives (or remove the laptop from the network connection then login) for the letter that shows up at home (probably F:\). Insert the FlashDr and the pc should now see it. Go to Computer Management (my computer, right click, select management, go to storage, disk management right click and select 'change drive letter'. Pick a letter that doesn't map.

You'll have to reconnect network drive, easist to logoff and back on or reboot. But that computer should now recognize your FlashDr as the new letter.

I have a Sandisk Cruzer memory stick plugged into my laptop as usual and no problems. I removed it and plugged in my Freecom Tough Drive and all is OK. Then, I plug my Cruzer back in and laptop can't see the Cruzer. So, I remove Freecom but laptop still can't see Cruzer. I remove both and reboot and laptop sees the Freecom but not the Cruzer. I try another USB stick in my laptop and it sees it OK. So, I try my Cruzer in another PC and it sees the Cruzer with no problems. I plug the Freecom into another PC, no problems there either. I'm baffled - any ideas?

Answer:Conflict with a Ext Hard drive and Sandisk Cruzer

Could be a conflict with two devices trying to use the same drive letters.Open Explorer, right click on "My Computer" and select Manage then Storage then Disc management. This will show the discs available on the computer. If you right click on a drive you will see an option to change drive letter.Make sure you use a different drive letter for each device.Note than some discs may have more than one partition, each of which needs a drive letter.

SanDisk Cruzer 512mb Mini - Needs to be formatted somehow?????

So, it appears that you are having the same problem that I am having. Here is how my problem happened. I had it plugged into a computer that I was about to Fdisk and format. I thought that there was a small partition on this hard drive of 512mb, so I removed the partition, only to realize that the partition I removed was my SanDisk 512mb memory stick....So, any luck getting yours back. Essentially, you should be able to fdisk or create a partition and format again, but it doesn't work like a hard drive. It keeps asking me to insert a disk into my Drive E (the drive letter that is designated). On yours it could be E or F or whatever....Can't seem to get any help from SanDisk on line, so I am searching around the net. My e-mail address is [email protected] if anyone can help. Thanks. JT

Had used this to transfer info from an XP Pro machine to a 98/SE machine.
Worked fine for several weeks.

I wasn't aware of the USB Removal tool on the XP machine, so was
unplugging it hot.

Now it's quit accepting files (says the file cannot be created on the drive).
Properties shows it to be full, but the drive file window doesn't show any files.

Have tried to reformat, but maybe I'm not doing something right?

I am not certain into which category I should post this because it crosses Windows and Mac borders, but:

I just recently purchased a SanDisk cruzer mini 2.0 GB flash drive.

I run 2 Mac minis and a Compaq with Windows/XP. I attempted to copy the Compaq Documents folder to the SanDisk as the Compaq is being replaced with another Windows machine and I want to preserve the data. I also dumped the email and Contact info for later import.

I did the copy on the Compaq (using one of the USB connections):

When looking at the data on my mini:
-I discover that embedded folders/directories did not consistently copy- (the embedded FOLDERS, even several layers deep did copy), the DOCUMENTS did not. But documents in the first level (inside no folder except DOCUMENTS) DID copy.
-Then when I attempted to delete the (empty) folders the SanDisk hung. Then I restarted (nothing else would work) and attempted to replace the empty folders with real ones. Again the SanDisk hung.

Right now I feel like a I have a 2.0 GB necklace, but useless as a backup device.

Does anyone have a clue on what I can do to clear, then re-copy, the data?
