Using my sandisk cruzer glide (8GB), I was putting windows 7 onto the usb to install onto another PC. When halfway through, it said "This drive is read-only". I got confused, but then I went to computer and the I couldn't even open the drive. I checked it in diskmgmt.msc and it said "read only". Afterwards I checked the USB on gparted live and it turns out the partiton has changed to HFS+. After trying to rewrite the partition table (and it failing because of read-only) I tried using diskpart next  apparently I just had to do attributes disk clear readonly (with disk being the USB) but that did nothing. When doing attributes disk it still said Current read-only state: Yes even though below it says Read Only: No. I've also tried chipgenius, and only got this far:  Device Name: ++USB Mass Storage Device(SanDisk Cruzer Blade USB Device)  PnP Device ID: VID = 0781 PID = 5567 Serial Number: 2005485881119AF2F91A Revision: 1.20  Device Type: Standard USB device -   Chip Vendor: (No match record) Chip Part-Number: (No match record)  Product Vendor: SanDisk Product Model: Cruzer Blade  Tools on Web: (N/A)   What should I do now? I am completely out of ideas. (I have also tried BOOTICE, but that did nothing too)

When I plug in my USB flash drive, it shows up on my computer as write-protected or read-only. I am unable to transfer data to it, nor can I modify or delete any files already stored on it. I also cannot repartition or reformat the drive using Windows Disk Management, DiskPart, GParted, or other tools. The drive does not have a write-protect switch.  Why did this happen and what can I do about it? Is there a way to remove the write protection?  (Note that this can happen with some memory cards, too, as they often use controllers similar to those used in flash drives. In some cases, the system may report that the drive or card was formatted successfully even though it was never actually formatted; the original data reappears when the device is reinserted.)     This question comes up often and the answers are usually the same. This post is meant to provide a definitive, canonical answer for this problem. Feel free to edit the answer to add additional details.

I tried a few utils and none of them worked. Either USB wasnt supported or the drive was 'recognized'. I am trying to figure out if i should dump the drive or not. Its only a year old but the warranty is only a year which is a pity.

How can I tell which device the USB drive is assigned as?  Before inserting the USB drive:  $ lsblk NAME        MAJ:MIN RM   SIZE RO TYPE MOUNTPOINT nvme0n1     259:0    0 238.5G  0 disk  ├─nvme0n1p5 259:3    0  15.9G  0 part [SWAP] ├─nvme0n1p1 259:1    0 222.6G  0 part / └─nvme0n1p2 259:2    0     1K  0 part    After:  $ lsblk NAME        MAJ:MIN RM   SIZE RO TYPE MOUNTPOINT sda           8:0    1   1.9G  0 disk  ├─sda2        8:2    1   2.4M  0 part  └─sda1        8:1    1   1.2G  0 part  nvme0n1     259:0    0 238.5G  0 disk  ├─nvme0n1p5 259:3    0  15.9G  0 part [SWAP] ├─nvme0n1p1 259:1    0 222.6G  0 part / └─nvme0n1p2 259:2    0     1K  0 part    Is it /dev/sda??

When I type in lsusb, the device appears as ID 2357:0108  That's right, it's blank at the end. I've updated the usb ids yet its always blank. I have no idea what to install to make this thing work. I'm dual booting on mac osx

Depending on what's currently connected to a PC, a USB key does not always get the same drive letter.  This is an issue for me because I want to use this key as a backup destination, and I thus have to change the path that's used from time to time.  Is it possible to make sure that a specific key always ends up with the same letter?

Aiming to have a large internal HDD to store files, and several OSes on separate disks. They all need to read and write to one storage drive.  Ubuntu (13.04+) Mac OSX (10.8+) Windows (7+)   What format should the drive be? Would like to avoid buying third party software, here's what I have discerned so far:   NTFS - Can't be written to by Mac without buying third party software?      ext3 - Windows can't read, . Mac has  HFS+ -  exFAT - , but

I have a bunch of SD cards that do not have the little plastic switch for the read only setting. so Windows thinks it’s write protected or something. The card is not write protected by the software lock present on the SD card standard.  I’m using one with tape over the notch and it’s ugly. Also, the Thinkpad slot drags on the tape all the time so I’m afraid it will might loose in there eventually.  So, is there any way to tell Windows to ignore this lame write-protect feature?  I’m not interested on the SD card itself as it’s irrelevant for the issue at hand. Read this question as being about a 5.25” floppy disk drive instead of an SD card if you wish. I’m pretty sure the Windows settings are the same for both, really.  I’m  that there are 3 ways to secure an SD card. I’m talking about only the mechanical switch, which is the responsibility of the host to handle.

I have a  16GB USB flash-drive:     The weird part with this USB flash-drive is that despite the fact that I have zero-filled the flash-drive:   # dd if=/dev/zero of=/dev/sdc bs=10M dd: writing `/dev/sdc': No space left on device 1490+0 records in 1489+0 records out 15614803968 bytes (16 GB) copied, 3837.37 s, 4.1 MB/s #    ..it still represents itself like it has a partition on:  # fdisk -l /dev/sdc*  Disk /dev/sdc: 15.6 GB, 15614803968 bytes 64 heads, 32 sectors/track, 14891 cylinders, total 30497664 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00000000  Disk /dev/sdc doesn't contain a valid partition table  Disk /dev/sdc1: 241 MB, 241172480 bytes 64 heads, 32 sectors/track, 230 cylinders, total 471040 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00000000  Disk /dev/sdc1 doesn't contain a valid partition table #    gdisk shows different GUID for both /dev/sdc and /dev/sdc1.

Since I removed the USBs drive letter for the raw partition per the instructions , Windows 7s "Safely Remove Hardware..." taskbar icon no longer detects my USB. So, how should I safely remove my USB?  There doesn't seem to be anything on this problem in the TrueCrypt .

I have a blank USB flash drive I want to put a new filesystem on. If I try adding a new partition it complains "No partition table found on device /dev/sdc". Creating a msdos partition table seems to work correctly, except that when I go to add a new partition it complains with the same error. What am I missing?

I have a USB where I'm coping an ISO of 5 Mb aprox with a small OS with its own grub. If I connect the device and check it sudo fdisk -l I get:  ... Device     Boot Start   End Sectors  Size Id Type /dev/sdb1  *        1  9551    9551  4.7M cd unknown   If I copy with dd the ISO sudo dd if=my_os.iso of=/dev/sdb   14852+0 records in 14852+0 records out 7604224 bytes (7.6 MB) copied, 0.538487 s, 14.1 MB/s   It works perfectly. An boot from BIOS in other PC.  The problem is, sometime I forget to connect the USB after update the BIOS, so I do ff WITHOUT the USB connected,  the output is:  14852+0 records in 14852+0 records out 7604224 bytes (7.6 MB) copied, 0.00987684 s, 770 MB/s   Now, the /dev/sdb register is corrupted, the copy speed (770 MB/s) have no sense, and cannot user again dd until reboot.  I have tried to repair it with ddrescue and it doesn't work  sudo ddrescue /dev/zero /dev/sdb conv=noerror,sync   My question is, what is happening exactly and if is possible, how to repair /dev/sdb to avoid reboot and dd start working again?  Thanks.

I have a USB drive (SanDisk SDCZ40-016G) that mounts in a way I've never seen before. When inserted, two items appear in Places -> Computer:    "SanDisk Ultra Backup: 16GB" contains my data, and "CD Drive: U3 System" contains a Windows executable. The part with the Windows executable doesn't look useful to me so I'd like to remove it. I used GParted to delete the only partition listed on the device and then I created and formatted a new partition:    Strangely, the "CD Drive" containing the Windows executable was perfectly intact after this operation.  What's going on?

I'm not even sure if i worded my question right but, I'm familiarizing myself with Ubuntu and want to install it on a new desktop I just finished putting together so I'm trying it on my laptop via live usb first.    I had trouble mounting my NTFS windows partitioned disks, solved that problem but I also see a disk that has the exact amount of memory I alloted for persistence. I try to access it but it shows the same ACL error I got when my NTFS disks weren't mounting.    I've already downloaded some stuff and made some things with LibreOffice and want to know if those things have been save automatically or if I have to mount the usb disk for it to be persistent.

I have a following problem: when I plug-in my USB flash drive, it isn't shown in Windows Explorer or recognized by system at all. In device properties, it is shown as:     USB MEMORY BAR     There's no partitions on the drive, so I can't format it:    DISKPART:     Virtual Disk Service error:   There is no media in the device.   HP USB format tool:     There is no media in the specified device.   Any help will be greatly appreciated! Thank You!

When you want to create a bootable usb memory stick, then you must identify as a sudoer. Why is that? I have no difficulty understanding why unprivileged users shouldn't be allowed to fiddle with the installed system, but why shouldn't you be allowed to copy grub onto the memory stick if you have write access to it?

Recently, I bought an USB flash drive which has a cool design.  The seller said it is 256GB however, I've already known that capacity would be fake. Anyway, I bought it cause of its cool design and want to use this USB flash drive anyway.  What should I do?  I've tried to find a proper tool(vid 1908 / pid 1320) but couldn't. Can I repair this through Low level format? Or partitioning this through Linux?
