I've been having some issues with my usb external hard drive it's a Toshiba 350 GB about a little over a year old and up to this month it had no issues that I noticed.
I was about to do a backup of my regular hard drive onto it but first I wanted to free up some space. I attempted to do an online backup and started getting read errors after about 10 percent through a small test folder. Puzzled I tried running a scan disk f. For some reason it ran twice the first completing after some time finding a lot of unreadable files and the second failing to move after several hours at 2 percent in verifying folders and files. The same thing happened with chkdsk /r Figuring something was up I then attempted to rescue my files off the external. I could not get everything off as I got several crc redundancy errors but I got everything I basically wanted.
I then attempted to do deep reformat through windows which failed after hanging for several hours at 54 percent. A quick reformat however quicky purged the drive in under half a minute. (since the full one checks for errors I'm not surprised)
I then attempted again to do a chkdsk /r after the quick reformat. I didn't restart the computer however I went to the run box typed in cmd /chkdsk /r and chose to dismount before running. For what seemed like 2 hours it froze at 54 percent of stage 5 then 59 and after a few minutes 69. It stayed at 69 for about 2 to 3 hours before ratcheting up to 74 around the time I considered calling it quits. I'm not sure what to do at this point (besides considering buying a replacement drive) I've heard that it's not good to stop a chkdsk but its been at 74 percent since 3 am! I'm currently going to be away for 2 to 3 days and am wondering if I should leave the thing on and pull the plug if it hasn't budged by the time I come back. I'm leaning towards the notion that the drive is finished but because it's no longer covered by warranty I want to see if by some miracle chkdsk actually finishes. Should I bother? Should I connect the drive to another machine to run the chkdsk? I've had a suspicion my RAM is going bad and I heard somewhere that can somehow effect how efficient chkdsk is.
One other quick question I was searching in eventviewer for the original chkdsk f log which i think should be under winnit but I could not find such an entry. Might it be elsewhere? Seeing whether or not there were bad clusters would make this decision much easier. Thanks!
