Defragging external HD in W7 64 bit

  john bunyan 19:25 13 Dec 2009

Just changed from XP to W7 64 bit. My data is backed up in an external USB HD. When I used to (with MS XP defrag) defragment it, because I often deleted stuff and replaced it, defrag took a while and I could follow progress. I did actually drop this drive, but it seems to be working ok, with all folders visible ad accessable. However when I attempt defragging, it seems to stop at "Pass 1" 1% consolidated. In "My computer" it shows as 0% fragmented, but this is hard to believe. Any views? Does Defraggler (Piriform) work in W 7 64 bit; is it worth obtaining it?

Anyone with views?

Hi JB....different Defrag engines have varied methods in the way they analyze disk sectors/blocks etc:
Dropping the drive could have a bearing on the scan output you are seeing as this could be down to the read heads not traversing across the platters correctly..My advice is to try Auslogics Disk defrag..Its' a well behaved defragger and you can get it from click here .The Auslogics home site was under maintainance an hour or so ago and not available.
Try running a defrag with Auslogics (It's W7 and 64Bit capable) If you still get Defrag "read errors" the "Drive Drop" may have shook things up a bit too much..The tolerances between "Read Head" and Disk Platter are very fine and easily upset...

Thanks, Sonyboy, as usual. I will try Auslogics. The drive seems readable ok and I wonder if W 7 needs less? Anyway I have a second external HD which I will use as a back up as well in case the dropped one packs up.

Thanks, it did work. I suspect that I was a bit impatient with the Win 7 defragger - it was running slow, and due to the lack of information (I liked the progress report in XP) I got impatient and stopped it. Also I dislike the auto back up in W 7 which compounded the problem as it started as I was defragging the external drive where the W7 back up is stored. I prefer to do my own back ups etc with ATI 2010. I will use Auslogics defragger in future as it gives a more visual progress report.

• Step 1 Go to Start > Control Panel > System and Security. Under the Administrative Tools Section, Click on Defragment your hard drive.
• Step 2 The Disk Defragmenter will open. To run a Disk Defragment on a schedule, click on "Configure schedule..." To manually defragment your hard drive or hard drives, skip to Step 4.
• Step 3 You can schedule the Disk Defragmenter to run on a daily, weekly, or monthly basis. However, you aren't likely to see any benefit running a defrag any more than once per month.

Choose a frequency, day, and time and click "OK."

• Step 4 To manage your disk defragment manually, click to select the disc or discs under "Current status" that you'd like to defrag, and then click "Analyze Disk.
• Step 5 After the Disk Analysis is complete, Windows 7 will indicate if a defrag is recommended. Check the fragmentation percentage under "Last Run." If it is higher than 10%, running a disk defrag is recommended.

Click "Defragment Disk."
• Step 6 The Disk Defragment process can take a few minutes to a few hours depending on the size of your drive and the degree to which it is fragmented.
