This is a first for me, and I hope someone knows the answer. I use my external harddrive to backup media and documents about once a week. I skipped a couple weeks over the holidays, and when I got back my external harddrive is blank. It is recognized by both my computer and laptop but is shown as empty. The computer says that all its memory is available, and I can transfer files to and from it. Is all my old data gone for good? And can I trust it to hold data again?
External Harddrive: Acomdata HD080U2FE-72 Format: NTFS OS: Windows XP

You have to backup all the require data to an external storage media first. If your are not familar with the software data backup. Ask your principal help or the person who operate on the system, to backup their vital data for to the external storage media, because you don't know which files are important.
Once you have install the OS, On installing "My Invoices & Estimates Deluxe" make sure the name the company file the exact same as the back up file name. If not you will not be able to load the backup files ie. you get errors opening the backup files.
I had a similar issue with windows 2008 and windows 7. the drive lost all its info and had to be reinitialized under both of those O.S.'s.. You can try that as long as it doesn't have any data you need.. Once you do that the drive will work and you can start using it. The file system under vista and above is slightly different than xp.
initially, pls verify that it is indeed an external storage problem rather than a laptop USB issue by trying other USB devices and determine if they are recognized and working;
disassemble the enclosure of the Acomdata external hard drive and remove the actual hard drive;
you would need the use of a 2nd PC, a desktop that could accommodate the HD from the Acomdata (IDE or SATA);
install the HD from the Acomdata as a Secondary Master or Slave internally to the 2nd PC;
boot the 2nd PC and determine if the HD from the Acomdata will be recognized as a local drive;
chances are that the partition of the HD from the Acomdata was messed up. This would explain the blinking blue light;
download and install a file recovery program. An example is GetDataBack (unfortunately not a freewarebut DEMO is available) and do a recovery. It would take some time based on the size of the HD from the Acomdata;
temporarily save the recovered data in the 2nd PC. You can burn this likewise into a DVD backup should the 2nd PC be capable of that;
after recovery, re-partition and format the HD from the Acomdata while still attached to the 2nd PC;
should the re-partition and format be successful, you can transfer back the temporarily saved recovered files;
a nice, simple, fast and safe partitioning/formatting software is Partition Magic (unfortunately not a freewarebut FREE TRIAL is available).
should the re-partition and format be not successful, you can replace only the HD and/or claim warranty.
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.
Good luck and kind regards. Thank you for using FixYa.
Once you save the data on the external drive it will stay there until you delete it from the external drive. I personally run (2) 1 terabyte external drives and I save My data on 2 separate drives. I have had them fail in the past. This is the only way to ensure you will always have a good copy no matter what. At the time I had only 1 500gb external hard drive and it was nearly full. I bumped it when it was running and lost every thing I had! With the low cost of external drives I recommend buying two of what ever capacity you require and making redundant backups, this will assure you your data will be safe.

If the problem is in the controller inside the case which in 99 percent of the times it is, This will certainly fix your problem. The MTBF(mean time between failure) of harddrives is 100,000 hours of operation. Also, any external case can be used that matches your hard drives specs...size, IDE, SATA ect...
What is the filesystem format on your external hard drive?
there are limits on certain file systems, like maximum size of a single file in fat32 is 4gb.
let me know the filesystem on your external hard drive and i will try to consult a few friends for you.
