As partitioning software, AOMEI Partition Assistant is as good as any program I've seen. It enables you to do almost anything with disks and partitions. The standard version is more than adequate for most users, and the pro version is as good as it gets. I have some nits concerning, but the Windows To Go trick trumps those gripes big time.
I'm a professional computer tech with my own concierge business. I've researched plenty of similar software. Yours is the best in the world! I basically gave up on trying to switch my HDD to GPT without formatting it. I found AOMEI partition assistant and switched it in seconds without deleting all my stuff! Keep up the great work.
Hi, I’ve been building PCs with Windows/Unix/NeXTstep since 1987.Your partition Assistant is AWESOME! I restored a 256GB SSD backup to a new 512GB SSD and got the dreaded “unallocated partition not next to active partition” issue. Your Partition Assistant fixed it in like 15 seconds, and that time is with me choosing the options! You guys are the best! Thanks!
Thank you for your product. I used it last night to copy my OS drive to a new, larger SSD. The process worked well, although it did generate an error when the copy completed but I was able to successfully boot from the copy. I also used your product to convert my MBR disk to GPT. Partition Master is a fabulous product and I thank you for it.
