I keep all of my personal files on an external hard drive. That 1TB hard drive was getting full, so I bought a new 2.5TB hard drive. I start working from the files on the new drive. After about 30 seconds or so, folders just show as 0 bytes and "There are no files in this folder". The hard drive works on other computers (HP laptop) but not my Dell desktop. This has happened (sort of) with three different, brand new external hard drives. What would cause this?
Super Long Version
I'm running a Dell Precision T5400 workstation with Windows 7 64Bit Home Premium. I keep two 1TB redundant drives at all times, synced monthly via SyncToy. The 1TB drives were filling up so I bought two 2TB Seagate external drives. And then this string of events happened:
1) Copied all of the data from the 1TB to a 2TB SEAGATE drive.
2) SyncToy'ed them to ensure that all of the data was definitely there.
3) Retired the old 1TB drive.
4) Began to duplicate the 2TB drive to the other 2TB drive.
5) In the middle of copying, I received the error, (something like) "Cannot copy files as the source file no longer exists".
6) Checked Disk Manager, and the 2TB drive shows up as RAW format now?! It was originally NTFS. Search Seagate forums and you'll find that this is a common problem.
7) Restart. Same problem. The other 2TB SEAGATE drive now has "USB device not recognized" errors.
8) Try restarting, copying over and over. Same results.
9) Plug both drives into my work laptop (Mac Bootcamp Windows 7 64bit). Both show up as "Drive needs to be formatted to proceed".
10) I format both of them and perform check disks on my Mac Laptop.
11) They're fine. Then I plug them into my Dell Desktop
12) I run SeaTools on them. One has an error and can be RMA'd. The other is "USB device not recognized". I RMA them both and mail them in.
At this point, I hate Seagate because they seemingly sold me two faulty 2TB drives.
13) I buy two new 2.5TB Western Digital Hard drives. (expensive. btw).
14) I un-retire my old 1TB drive and plug it into my Mac Bootcamp laptop. Disk has errors. Run the recovery tool. All seems well.
15) I copy my 1TB to one of the 2.5TB WD drives on my HP laptop (it's super old, and I had to go to work with my Mac)
16) I plug in the new 2.5TB drive to the Dell Desktop, and some of the folders show up empty?!?
17) Plug that drive back into the old HP Laptop all of the files show up.
At this point, I'm super confused. There's clearly something wrong with my desktop?
18) I perform the following while checking the disk in between each new trial: system restore, uninstall USB drivers/host controllers, start in safe mode. Nothing works. Same problem. Folders show as empty.
19) Plug the drive back into the HP laptop. Files are there.
20) Re-install BIOS on the desktop. Folders show as empty.
21) Run Malwarebytes, HiJackThis... nothing out of the ordinary.
22) The computer doesn't fully start up when the 2.5TB WD drive is plugged in.
23) I run startup recovery. It spits out a bunch of errors. Fixes some, some not.
24) Folders show as empty.
25) I post this long post to BleepingComputer.
If you read all of this: THANK YOU THANK YOU THANK YOU. I am so confused about this. Some thoughts are:
- Does my Dell Desktop not handle drives larger than 2TB?
- Is there something wrong with my USB ports?
- Other weirdness, I plugged in another USB drive (500GB) to this computer and it works fine.
