Cannot successfully format HDD in External USB Hard Drive Enclosure (Cypress AT2LP)
Posted on 2006-05-04
I'm having a problem with a HDD in an External USB enclosure. The enclosure is manufactured by Mad Dog Multimedia (MEGAVAULT 3.5" USB Anodized Aluminum Enclosure) and, up until a few days ago, it was working perfectly. Then, all of a sudden, XP starts asking me whether I want to format the drive every time I try to access it.
The HDD itself is fine - I verified it using SeaTools Desktop Edition and it passes all tests when installed internally on a PC.
I have tried to re-partition and format the HDD while it is in the USB enclosure. Partitioning seems to work fine - both Windows and Partition Magic do not report any errors when I partition the drive. However, I cannot format the drive successfuly when it is connected to my computer via the USB enclosure. I have tried formatting with Windows Disk Manager, the FORMAT command and through Partition Magic (v8) - all to no avail. I have also formatted the drive internally on a PC and then tried to access it via the External USB enclosure, but all I get is a XP's kind offer to format my drive.
-= Error Codes & Observations =-
Windows Disk Manager formats the drive to 100% and then returns the following error message: "The format did not complete successfully."
Partition Magic returns error code 626 - stating that it cannot access the drive at boot time.
Both Windows Disk Manager and Partition Magic are able to make partitions on the drive (I have verified the successful partition creation by re-installing the drive internally on a PC and checking with FDISK)
Just to reiterate - the drive does appear in My Computer and I can click on it.
Also, I believe my USB enclosure uses a Cypress AT2LP high-speed USB controller. I have checked with the manufacturer and there are no firmware updates.
