Hello,

I recently purchased a second-hand Transcend Storejet  25h3 1TB external hard drive, connected via USB 3.0.  It doesn't show up as an available device or drive from the menu on my Microsoft Surface Pro 4, but I can select it from the Safely Remove Hardware and Eject Media tab on the toolbar to disconnect it.

Please can anyone help me?

Many thanks.

Marti

    Hi,

    Your Transcend has no drive letters assigned, which is probably why it is not showing up properly..

    If you did not install or clone Windows to it, it must have been being used as some type of a boot drive previously.. Are you interested in saving anything on the drive, or just want to wipe it and start fresh ?

    You may be able to delete the 931gb partition from within Disk Management.. I'm not so sure about the 200mb EFI partition.. You could try if you wanted..

    You might want to switch it to a MBR drive as well.. Because it has a EFI partition it is p[robably a GPT which is required for UEFI Bios..

    All of these suggestions are available by right clicking on the Disk 1 or the individual partition, depending upon what you want to do..

    I would not advise assigning a drive letter to any partition prior to wiping it, as it may disrupt your normal OS drive..

    Hi,

    Look in Disk Management.. It may just need a drive letter assigned..

    Hi Marti,

    Thank you for writing to Microsoft Community Forums.

    Seems that the Transcend Storejet 25h3 1TB external hard drive is not showing as available device on the PC. We’ll certainly assist you to fix the issue. In order to get clarity and to assist you accordingly, please reply with the answers to the questions below:

    • What is the Version and Build of Windows 10 installed on the PC? (Type winver in Windows search/Run command)
    • Did you try connecting the hard drive on another device?
    • Does is it show as unallocated in disk management page?

    Please help us with the screenshot of the Disk management window after connecting the hard drive (Press Windows + x key and select disk management) for further investigation.

    You may also refer this article from transcend as an additional information: My computer cannot recognize my StoreJet, and the OS asks me to format my StoreJet (external-HDD). What should I do if data transferring is being interrupted?
