I have a 2TB external hard drive that I'm trying to format, however, although the computer recognizes the hard drive it isn't allowing me to name or format the drive. I'm running Windows XP. The hard drive was previously formatted on a Windows 98 PC.

Any suggestions would be helpful. Thanks.

Good troubleshooting so far from and — Disk Management seeing the disk but refusing operations usually points away from a simple “rename” problem and toward one of three things: the USB enclosure/bridge presenting odd geometry or locking the disk, a partition-table/size compatibility issue (MBR vs GPT), or a hidden/firmware area on the drive (HPA/DCO). For context on MBR/GPT and the 2TB boundary, see the GPT reference. (en.wikipedia.org)

Recommended, non-destructive sequence (in order of least-to-most-invasive):

  • Test the drive on a different Windows machine (Windows 7/10 will often handle odd cases XP won’t).
  • If possible, remove the disk from the external case and attach it to an internal SATA port (this bypasses USB-to-SATA bridge firmware which commonly causes “can see but can’t touch” behavior).
  • If the disk is still visible but not format-able, use DiskPart from an elevated command prompt to wipe/initialize and recreate a single NTFS volume (DiskPart is the supported CLI for this). Example DiskPart steps: 
diskpart
list disk
select disk N      # pick the disk number that matches the 2TB drive
clean
create partition primary
format fs=ntfs quick label=Backup
assign
exit

See Microsoft’s DiskPart documentation for details and safety notes. (learn.microsoft.com)
If Windows XP is the only available host and an exFAT volume is desired, XP requires Microsoft’s exFAT update (KB955704). (learn.microsoft.com)

Caveats and rarer causes: Windows’ GUI has long had limits for creating FAT32 volumes >32GB (use NTFS or apply special tools if FAT32 is required). (arstechnica.com) Also consider hidden firmware areas (HPA/DCO) or vendor write-protection on some enclosures — these require vendor utilities or low-level tools to detect/clear and can be destructive, so avoid destructive fixes if the data must be preserved. (forensics.wiki)

If all else fails, the enclosure is a common single-point failure; replacing it with a known-good USB‑SATA dock or connecting the drive directly to SATA usually resolves these symptoms (data‑first approach recommended). (300dollardatarecovery.com)

Hello,

In disk manager did you right click on the partition > properties, type a name and click apply/ok?

- Let us know how it goes.

Tried that and all that comes up is "Help?" I think I'm going to have to pull it out of its case and plug it directly into a desktop and see if that works.

Well, erase your hard drive and see whethers your hard drive allow itself to do so. Go and erase it, after that type in a name for the hard drive and all is well. Now you can use the hard drive. Hopes it helps

try this .. goto command prompt,, type the following command format X: /fs:ntfs or fs:fat32 where x is the name of your drive.. hope it works..
