Weird Macrium Reflect error
"The USB disk contains the maximum number of partitions allowed"
Macrium Reflect needs to make a new partition? As far as I know, being freshly formatted in current Windows 10, the USB flash drive has one partition. Copied a file to it. The file opens just fine. Something weird about Windows 10 format nowadays? The authors have developed a distaste for Windows? Thanks. |

It could be a false positive coming from some GPT info the program has detected. And this wouldn't be the first time, that uncleaned GPT info did that either. (Other tools will make bogus claims, if you don't do a good job of cleaning GPT off before switching back to MBR.) And I can't give you a good reason, why these softwares are doing that kind of sniffing either. In Linux, you can put four partitions (in MSDOS legacy MBR mode), and Linux can use all four. If the device is then handed to Windows, only the first partition mounts, and the last three are ignored. Windows supports one partition that way. I don't know whether putting GPT on the stick, changes the behavior or not. You can use HxD to examine the first blocks of the stick and make sense of it. As far as I know, a USB stick can begin with an MBR sector, or the first sector of the file system can be located at Sector 0 (no MBR). In the latter case, obviously there is zero possibility of adding another partition (linux or not) - without an MBR, there's no partition table, and no way to bootstrap GPT. I don't know whether TestDisk will scan a USB stick. The best collection of USB flash trivia, is here. https://www.uwe-sieber.de/usbstick_e.html Paul |

Perhaps that means the one and only partition must be completely empty. I ran into that exact issue a few days ago, Macrium complaining about 'maximum number of partitions'. There was nothing on the USB stick that I wanted to keep, so I blew away the single partition with MiniTool Partition Wizard. With no partitions on the stick, Macrium happily created what it needed without further ado. |
