Hi, I am facing some issues regarding my Transcend HDD. It's not appearing in My Computer/Windows Explorer option however it is shown in windows notification icons as USB Mass storage installed. In Disk Management, the status of my ext disk shows as 'Unknown 465.76GB Not Initialized'. However, I can see my ext disk showing in Device Manager under Disk Drive and I can see the entry USB Mass Storage Device. I don't know why my ext Drive is not longer shown as E: drive in My Computer. In short: Before the status of my ext hard disk is: - My Computer: E: drive and correct name - Device Manager under Disk Drive - shown the model name - Disk Management - shown as NTFS Now - My Computer: disaappear - Device Manager under Disk Drive - shown the model name - Disk Management - shows 'Unknown 465.76GB Not Initialized' Will it erase all data from HDD if I select 'Initialise' option?

Can you please help further? Hi, I tried below things which are not working:( 1. I opened the disk management and the drive was in 'Online' status. I changed it to Offline and again made it 'Online'. I tried to find blue bar which would need a change in drive letter but could not find any blue bar and its a black bar instead.

Transcend Usb 3.0 Driver For Mac Pro

Uninstalled and re-installed the drivers for Transcend Storejet 500GB What i did not try yet is 'usbstor.inf' file option and 'initialise' option. I am afraid of storing usbstor.inf as mentioned in 1 of the options (copy code and save text file etc) as well as afraid of initialise option. @OtheHill: if i initialise the HDD, i hope the data will NOT be lost. Please advise. Thanks, message edited by rrege.

Hi, @OtheHill: To answer your doubts- -Full model number: Transcend`s 500GB StoreJet 25M -Backup software use: I did not try backup software tool from HDD -Same computer test: I tried HDD on my own Dell Inspiron laptop with Administrator login along with my office HP Probook laptop as other user login.Cable: I was using cable came with drive but with single usb port. And after this blunder, tried using both ends of cable at usb ports.Use of USB port: i m using HDD directly to a integrated usb port on laptop. There are two possible models. M2, which is USB 2.0 and M3 which is USB 3.0.

The M3 requires more power, which is the reason for the double USB connection. See the link below to determine which you have. The case color accents are different. There is also a support link there to deal with specific issues. As I stated above, IF all else fails you should be able to repair the partition, or recover data after a quick format, assuming you did not use their software, which can encrypt the data. I suggest you try their support process first.

2.5' USB powered externals are more problematic than AC powered 3.5' models. Also, External drives MUST be properly removed, or corruption may occur.

Bad External HDD Transcend StoreJet 1 TB 25H3 (USB 3.0) isn't showing in Disk Management. Pls read all the details.

Tnx in advance! My younger brother ignored virus checking for the HDD. Then he was asked to format it a few times. Then he ignored it also, after that he couldn't even access the drive, and then the drive stopped showing at all. He doesn't know what he did so the Windows can see it, but then when he enable it, he did chkdsk till about 95%, and the drive was showing once again.

Then he used EaseUS to recover the data, and he managed to do that but on his laptop which has 4 gb of RAM, and 50 gb of free hard disk space on the hard drive. Then he deleted some files from the external HDD and since it went to Recycle Bin, whe he deleted it he couldn't access the drive again. I gave him some advice about everything, but he wasn't listening to me when I said to him that he needs to copy or burn the important that if he opens the drive, he started deleting what he didn't need.

Now he gave me the drive because now again he's not showing in Disk Management and in Device Manager disk drive isn't showing and in USB controllers it shows a yellow triangle with an exclamation mark and I can't access it. When I plug it in, the backup button is glowing and I can hear that the HEAD is trying to read the data, I can hear it 3 times after about 15 secs, and then the backup button stops to glow and in Device Manager it's the same.

I really don't know what to do now. Uninstalling, disabling and updating driver software shows no results. It says that it's up to date and in Properties, tab General says: Location 0 (Port#0014.Hub#0001), and the Device Status: This device is working properly; tab Driver says: Driver date: 21.6.2006., Driver Version: 6.1.7600.16385.

So, do you have any suggestions for the second chance to access the data from the External HDD drive?
